General [Abstract]
GENERAL	NOTE 1:- GENERAL a. Kornit Digital Ltd. (the “Company”) was incorporated in 2002 under the laws of the State of Israel. The Company and its subsidiaries develop, design and market digital printing solutions for the global printed textile industry. The Company’s and its subsidiaries’ solutions are based on their proprietary digital textile printing systems, ink and other consumables, associated software and value-added services. b. The Company has established wholly-owned subsidiaries in Israel, the United States, Germany, Hong Kong and the United Kingdom. The Company’s subsidiaries are engaged primarily in sales, and marketing, except for the Israeli subsidiary which is engaged primarily in research and development and manufacturing. c. On January 31, 2017, the Company closed a follow on and secondary offering where by 8,625,000 ordinary shares were sold in the transaction to the public. The aggregate net proceeds received by the Company from the offering were $35,077, net of underwriting discounts, commissions and offering expenses. d. On May 15, 2017, the Company made an underwritten secondary offering of 4,250,000 ordinary shares by the Company’s largest shareholder. The Company did not receive any of the proceeds from the sale of the ordinary shares. e. The Company depends on five major suppliers to supply certain components for the production of its products. If one of these suppliers fails to deliver or delays the delivery of the necessary components, the Company will be required to seek alternative sources of supply. A change in these suppliers could result in manufacturing delays, which could cause a possible loss of sales and, consequently, could adversely affect the Company’s results of operations and financial position.

Significant Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES a. Unaudited interim consolidated financial statements: The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. In the opinion of management, the unaudited interim consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s consolidated financial statements. The balance sheet at December 31, 2017 has been derived from the audited consolidated financial statements of the Company at that date but does not include all information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2017, included in the Company’s Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (“SEC”) on March 20, 2018. The significant accounting policies applied in the Company’s audited 2017 consolidated financial statements and notes thereto included in the Annual Report are applied consistently in these unaudited interim consolidated financial statements, except for changes associated with the new revenue recognition standard for the six months ended June 30, 2018, as detailed in Note 2 (e). Results for the six months ended June 30, 2018 are not necessarily indicative of results that may be expected for the year ending December 31, 2018. b. Use of estimates: The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. Actual results could differ from those estimates. c. Impact of recently issued accounting standards: 1. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (Topic 842) “Leases.” Topic 842 supersedes the lease requirements in Accounting Standards Codification (ASC) Topic 840, “Leases.” Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and must be adopted using a modified retrospective approach, which (following the amendment in July 2018) requires lessees and lessors to recognize and measure all leases within the scope of this ASU using one of the following transition methods: (i) as of the beginning of the earliest comparative period presented in the financial statements, or (ii) as of the beginning of the period in which this ASU is adopted. There are additional optional practical expedients that an entity may elect to apply. The Company is in the process of implementing changes to its systems and processes in conjunction with the review of lease agreements. The Company will adopt Topic 842 effective January 1, 2019 and expect to elect certain available transitional practical expedients. The Company is evaluating the potential impact of this pronouncement. 2. In June 2016, the FASB issued Accounting Standards Update No. 2016-13 (ASU 2016-13) “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is evaluating the potential impact of this pronouncement. 3. In January 2017, the FASB issued Accounting Standards Update No. 2017-04 (ASU 2017-04) “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019; early adoption is permitted. The Company does not expect that this new guidance will have a material impact on the Company’s Consolidated Financial Statements. 4. In August 2017, the FASB issued ASU No. 2017-12 (Topic 815) Derivatives and Hedging — Targeted Improvements to Accounting for Hedging Activities, which expands an entity’s ability to hedge financial and nonfinancial risk components and amends how companies assess effectiveness as well as changes the presentation and disclosure requirements. The new standard is to be applied on a modified retrospective basis and is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements. 5. In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation - Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. This ASU supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees. The guidance is effective for the interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the potential effect on its consolidated financial statements. d. Recently adopted accounting standard: In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to revenue recognition: “Revenue from Contracts with Customers” (“ASC 606”), which outlines a comprehensive revenue recognition model and supersedes most current revenue recognition guidance. The Company adopted ASC 606 on January 1, 2018, using the modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. The new standard application had no material effect on the pattern of revenue recognition, nevertheless, the revenue recognition disclosure has been adjusted in accordance to ASC 606 guidance. See Revenue Recognition below for further details. e. Revenue Recognition: The Company generates revenues from sales of systems, consumables and services. The Company generates revenues from sale of its products directly to end-users and indirectly through independent distributors, all of whom are considered end-users. The Company recognizes revenues in accordance with ASC No. 606, “Revenue from Contracts with Customers”. As such, the Company identifies a contract with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to each performance obligation in the contract and recognizes revenues when, or as, the Company satisfies a performance obligation. Revenues from products, which consist of systems and consumables, are recognized at the point of time when control has passed, in accordance with the agreed-upon delivery terms. Revenues from services are derived mainly from the sale of print heads, spare parts, upgrade kits and sale of service contracts. The Company’s print heads, spare parts and upgrade kits revenues (collectively “Spare parts”) are recognized at the point of time when control has passed, in accordance with the agreed-upon delivery terms. The service contracts are recognized over time, on a straight-line basis, over the period of the service. For multiple performance obligations arrangements, such as selling a system with consumables, installation and training, the Company accounts for each performance obligation separately as it is distinct. The transaction price is allocated to each distinct performance obligation on a relative standalone selling price (“SSP”) basis and revenue is recognized for each performance obligation when control has passed. In most cases, the Company is able to establish SSP based on the observable prices of services sold separately in comparable circumstances to similar customers and for products based on the Company’s best estimates of the price at which the Company would have sold the product regularly on a stand-alone basis. The Company reassesses the SSP on a periodic basis or when facts and circumstances change. The Company periodically provides customer incentive programs including product discounts, volume-based rebates and warrants, which are accounted for as reductions to revenue in the period in which the revenue is recognized. These reductions to revenue are made based upon reasonable and reliable estimates that are determined according to historical experience and the specific terms and conditions of the incentive. Revenue disaggregated by revenue source for the six months ended June 30, 2018 and 2017, consists of the following: Six months ended June 30, 2018 2017 Systems $ 33,150 $ 28,766 Ink and consumables 25,700 21,640 Spare parts 6,621 4,168 Service contracts 1,525 1,117 Total revenue $ 66,996 $ 55,691 The following table presents revenue disaggregated by geography based on customer location: Six months ended June 30, 2018 2017 U.S $ 36,137 $ 28,422 EMEA 22,165 15,763 Asia Pacific 6,938 8,560 Other 1,756 2,946 Total revenue $ 66,996 $ 55,691 Contract liabilities include amounts received from customers for which revenue has not yet been recognized.

Fair Value Measurements [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 4:- FAIR VALUE MEASUREMENTS FASB Accounting Standards Codification (“ASC”) No. 820, “Fair Value Measurements and Disclosures” defines fair value and establishes a framework for measuring fair value. According to ASC No. 820, fair value is an exit price, representing the amount that would be received for selling an asset or paid for the transfer of a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value : Level I: Unadjusted quoted prices in active markets that are accessible on the measurement date for identical, unrestricted assets or liabilities; Level II: Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level III: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). The Company measures its marketable securities, foreign currency derivative contracts and the contingent payments obligation in connection with acquisition (the “Contingent Payments”) at fair value. Marketable securities and foreign currency derivative contracts are classified within Level II as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Contingent Payments are classified within level III as the valuation inputs are based on significant inputs not observable in the market. The below table sets forth the Company’s assets and liabilities that were measured at fair value as of June 30, 2018 and December 31, 2017 by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. As of June 30, 2018 Level 1 Level 2 Level 3 Total Assets: Marketable securities - $ 77,998 - $ 77,998 Total financial assets - $ 77,998 - $ 77,998 Liabilities: Payment obligation related to acquisition - - $ 356 $ 356 Foreign currency derivative contracts - 52 52 Total liabilities - $ 52 $ 356 $ 408 As of December 31, 2017 Level 1 Level 2 Level 3 Total Assets: Marketable securities - $ 74,372 - $ 74,372 Foreign currency derivative contracts - 45 - 45 Total financial assets - $ 74,417 - $ 74,417 Liabilities: Payment obligation related to acquisition - - $ 334 $ 334 Total liabilities - - $ 334 $ 334 The following table set forth the change of fair value measurements that are categorized within Level 3: Total fair value as of January 1, 2018 $ 334 Accretion of payments obligation 22 Total fair value as of June 30, 2018 $ 356 The fair value of the payment obligation related to acquisition was estimated based several factors of which the most significant is the Company’s revenue projections. The Company used a Monte Carlo Simulation of the triangular model with a discount rate of 15%. Payment obligation related to acquisition is revalued to current fair value at each reporting date. Any change in the fair value as a result of time passage is recognized in the financial expenses; any other changes in significant inputs such as the discount rate, the discount period or other factors used in the calculation, is recognized in operating expenses in the consolidated results of operations in the period the estimated fair value changes. Payment obligation related to acquisition will continue to be accounted for and measured at fair value until the contingencies are settled during fiscal year 2018. Accretion of the payment obligation related to acquisition is included in financial expenses, net.

Derivatives and Hedging Activities [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	NOTE 6:- DERIVATIVES AND HEDGING ACTIVITIES The Company follows FASB ASC No. 815,” Derivatives and Hedging” which requires companies to recognize all of their derivative instruments as either assets or liabilities in the statement of financial position at fair value. Accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging transaction and further, on the type of hedging transaction. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. Due to the Company’s global operations, it is exposed to foreign currency exchange rate fluctuations in the normal course of its business. The Company used derivative financial instruments, specifically foreign currency forward and option contracts (“Hedging Contracts”), to manage exposure to foreign currency risks, by hedging a portion of the Company’s forecasted expenses denominated in New Israeli Shekels expected to incur within a year. The effect of exchange rate changes on foreign currency hedging contracts is expected to partially offset the effect of exchange rate changes on the underlying hedged item For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains or losses from contracts that were not designated as hedging instruments are recognized in “financial income (expenses), net”. As of June 30, 2018, and December 31, 2017, the notional principal amount of the Hedging Contracts to sell U.S. dollars held by the Company was $5,836 and $3,651, respectively. As of June 30, 2018, the fair value of the Company’s outstanding derivatives designated as cash flow hedging instruments was $52 which is included within “Other payables and accrued expenses” in the balance sheet. As of December 31, 2017, the fair value of the Company’s outstanding derivatives designated as cash flow hedging instruments was $45 which is included within” Other accounts receivable and prepaid expenses” in the balance sheet.

Company’s shares: On January 31, 2017 the Company closed a follow on and secondary offering where by 8,625,000 ordinary shares were sold in the transaction to the public of which 2,300,000 were issued by the Company and 6,325,000 were sold by the selling shareholders (inclusive of 1,125,000 ordinary shares pursuant to the full exercise of an overallotment option granted to the underwriters). The aggregate net proceeds received by the Company from the offering were $35,077, net of underwriting discounts, commissions and offering expenses. b. Share option and RSU’s plans: A summary of the Company’s share option activity and related information is as follows: Number of shares upon exercise Weighted average exercise price Weighted- average remaining contractual term (in years) Aggregate intrinsic value (1) Outstanding at beginning of year 2,360,647 $ 10.76 8.05 Granted 3,333 13.40 9.64 Exercised (261,670 ) 5.69 8.79 Forfeited (99,326 ) 12.50 7.12 Outstanding at end of year 2,002,984 $ 11.5 7.78 $ 12,788 Exercisable at end of year 944,037 $ 8.67 6.95 $ 8,641 As of June 30, 2018, $7,124 in unrecognized compensation cost related to share options is expected to be recognized over a weighted average vesting period of 2.59 years. The weighted average fair value of options granted during the six months ended June 30, 2018 and 2017 was $18.05 and $10.81 per share, respectively. (1) Calculation of aggregate intrinsic value for options outstanding and exercisable as of June 30, 2018 is based on the share price of the Company’s ordinary shares as of June 30, 2018 which was $17.8 per share. A summary of the Company’s RSUs activity is as follows: Six months ended June 30, Outstanding at December 31, 2017 88,759 Granted 144,801 Vested (825 ) Forfeited (11,608 ) Outstanding as of June 30,2018 221,127 The weighted average fair values at grant date of RSUs granted for the six months ended June 30, 2018 and 2017 were $14.04 and $21.15, respectively. c. The Company’s Board of Directors approved Equity Incentive Plans pursuant to which the Company is authorized to issue to employees, directors and officers of the Company and its subsidiaries (the “optionees”) options to purchase ordinary shares of NIS 0.01 par value each, at an exercise price equal to at least the fair market value of the ordinary shares at the date of grant. Under the plans, options granted before 2014 generally vest in portions as follows: 50% of total options are exercisable two years after the date determined for each optionee, a further 25% three years after the date determined for each optionee and a 25% four years after the date determined for each optionee. Starting 2014, 25% of total options are exercisable one year after the date determined for each optionee and a further 6.25% at the end of each subsequent three-month period for 3 years. Under the Equity Incentive Plans and starting 2017, the Company grants Restricted Stock Units (“RSUs”). The RSU’s generally vest over a period of four years of employment. Options and RSU that have vested are exercisable for up to 10 years from the grant date of the options or RSU to each employee. Options and RSUs that are cancelled or forfeited before expiration become available for future grants. d. The following table sets forth the total share-based compensation expense included in the consolidated statements of operations for the six months ended June 30, 2018 and 2017: Six months ended June 30, 2018 2017 Cost of products $ 189 $ 204 Cost of services 152 83 Research and development 402 297 Selling and marketing 476 430 General and administrative 1,161 934 Total share-based compensation expense $ 2,380 $ 1,948 On January 10, 2017, the Company signed a master purchase agreement with Amazon Inc. under which 2,932,176 warrants to purchase ordinary shares of the Company with an exercise price of $13.03 were issued to Amazon as a customer incentive.

Significant Accounting Policies [Abstract]
Unaudited interim consolidated financial statements:	a. Unaudited interim consolidated financial statements: The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. In the opinion of management, the unaudited interim consolidated financial statements include all adjustments of a normal recurring nature necessary for a fair presentation of the Company’s consolidated financial statements. The balance sheet at December 31, 2017 has been derived from the audited consolidated financial statements of the Company at that date but does not include all information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2017, included in the Company’s Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (“SEC”) on March 20, 2018. The significant accounting policies applied in the Company’s audited 2017 consolidated financial statements and notes thereto included in the Annual Report are applied consistently in these unaudited interim consolidated financial statements, except for changes associated with the new revenue recognition standard for the six months ended June 30, 2018, as detailed in Note 2 (e). Results for the six months ended June 30, 2018 are not necessarily indicative of results that may be expected for the year ending December 31, 2018.
Use of estimates:	b. Use of estimates: The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. Actual results could differ from those estimates.
Impact of recently issued accounting standards:	c. Impact of recently issued accounting standards: 1. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (Topic 842) “Leases.” Topic 842 supersedes the lease requirements in Accounting Standards Codification (ASC) Topic 840, “Leases.” Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and must be adopted using a modified retrospective approach, which (following the amendment in July 2018) requires lessees and lessors to recognize and measure all leases within the scope of this ASU using one of the following transition methods: (i) as of the beginning of the earliest comparative period presented in the financial statements, or (ii) as of the beginning of the period in which this ASU is adopted. There are additional optional practical expedients that an entity may elect to apply. The Company is in the process of implementing changes to its systems and processes in conjunction with the review of lease agreements. The Company will adopt Topic 842 effective January 1, 2019 and expect to elect certain available transitional practical expedients. The Company is evaluating the potential impact of this pronouncement. 2. In June 2016, the FASB issued Accounting Standards Update No. 2016-13 (ASU 2016-13) “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is evaluating the potential impact of this pronouncement. 3. In January 2017, the FASB issued Accounting Standards Update No. 2017-04 (ASU 2017-04) “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019; early adoption is permitted. The Company does not expect that this new guidance will have a material impact on the Company’s Consolidated Financial Statements. 4. In August 2017, the FASB issued ASU No. 2017-12 (Topic 815) Derivatives and Hedging — Targeted Improvements to Accounting for Hedging Activities, which expands an entity’s ability to hedge financial and nonfinancial risk components and amends how companies assess effectiveness as well as changes the presentation and disclosure requirements. The new standard is to be applied on a modified retrospective basis and is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of adoption on the Consolidated Financial Statements. 5. In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation - Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. This ASU supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees. The guidance is effective for the interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the potential effect on its consolidated financial statements.
Recently adopted accounting standard:	d. Recently adopted accounting standard: In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to revenue recognition: “Revenue from Contracts with Customers” (“ASC 606”), which outlines a comprehensive revenue recognition model and supersedes most current revenue recognition guidance. The Company adopted ASC 606 on January 1, 2018, using the modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. The new standard application had no material effect on the pattern of revenue recognition, nevertheless, the revenue recognition disclosure has been adjusted in accordance to ASC 606 guidance. See Revenue Recognition below for further details.
Revenue Recognition:	e. Revenue Recognition: The Company generates revenues from sales of systems, consumables and services. The Company generates revenues from sale of its products directly to end-users and indirectly through independent distributors, all of whom are considered end-users. The Company recognizes revenues in accordance with ASC No. 606, “Revenue from Contracts with Customers”. As such, the Company identifies a contract with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to each performance obligation in the contract and recognizes revenues when, or as, the Company satisfies a performance obligation. Revenues from products, which consist of systems and consumables, are recognized at the point of time when control has passed, in accordance with the agreed-upon delivery terms. Revenues from services are derived mainly from the sale of print heads, spare parts, upgrade kits and sale of service contracts. The Company’s print heads, spare parts and upgrade kits revenues (collectively “Spare parts”) are recognized at the point of time when control has passed, in accordance with the agreed-upon delivery terms. The service contracts are recognized over time, on a straight-line basis, over the period of the service. For multiple performance obligations arrangements, such as selling a system with consumables, installation and training, the Company accounts for each performance obligation separately as it is distinct. The transaction price is allocated to each distinct performance obligation on a relative standalone selling price (“SSP”) basis and revenue is recognized for each performance obligation when control has passed. In most cases, the Company is able to establish SSP based on the observable prices of services sold separately in comparable circumstances to similar customers and for products based on the Company’s best estimates of the price at which the Company would have sold the product regularly on a stand-alone basis. The Company reassesses the SSP on a periodic basis or when facts and circumstances change. The Company periodically provides customer incentive programs including product discounts, volume-based rebates and warrants, which are accounted for as reductions to revenue in the period in which the revenue is recognized. These reductions to revenue are made based upon reasonable and reliable estimates that are determined according to historical experience and the specific terms and conditions of the incentive. Revenue disaggregated by revenue source for the six months ended June 30, 2018 and 2017, consists of the following: Six months ended June 30, 2018 2017 Systems $ 33,150 $ 28,766 Ink and consumables 25,700 21,640 Spare parts 6,621 4,168 Service contracts 1,525 1,117 Total revenue $ 66,996 $ 55,691 The following table presents revenue disaggregated by geography based on customer location: Six months ended June 30, 2018 2017 U.S $ 36,137 $ 28,422 EMEA 22,165 15,763 Asia Pacific 6,938 8,560 Other 1,756 2,946 Total revenue $ 66,996 $ 55,691 Contract liabilities include amounts received from customers for which revenue has not yet been recognized.
