Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Description of Business . Revenue Recognition Cash and Cash Equivalents Fair Value of Financial Measurements . The hierarchy is divided into three levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records certain financial assets and liabilities at their carrying amounts that approximate fair value, based on their short-term nature. These financial assets and liabilities included cash and cash equivalents, accounts receivable and accounts payable. At December 31, 2015, the Company had $9,490,000 of available-for-sale investments. The Company had no available-for-sale investments at December 31, 2016. Available-for-sale securities were carried at fair value with unrealized gains and losses reported as a component of shareholders’ equity as accumulated other comprehensive loss, net of tax. Fair value for available-for-sale securities was based on quoted prices for similar assets in active markets or quoted prices for identical or similar assets in markets in which there were fewer transactions (Level 2). Amortization of premiums or discounts arising at acquisition, and gains or losses on the disposition of available-for-sale securities were reported as other income. Realized gains and losses, if any, were calculated on the specific identification method and were included in other income in the statements of operations and comprehensive income (loss). Accounts Receivable . Changes in the Company’s allowance for doubtful accounts are as follows: December 31 2016 2015 Beginning balance $ 79,000 $ 89,000 Bad debt provision 67,000 (5,000 ) Accounts written-off (5,000 ) (5,000 ) Ending balance $ 141,000 $ 79,000 Inventories December 31 2016 2015 Raw materials $ 123,000 $ 69,000 Work-in-process 27,000 4,000 Finished goods 175,000 318,000 $ 325,000 $ 391,000 In connection with the discontinued sale of The Like Machine, as of December 31, 2016, the Company deemed the value of the on-hand inventory related to The Like Machine to be impaired and recorded a $173,000 increase to the obsolescence reserve. Property and Equipment Production tooling, machinery and equipment 1 - 6 years Office furniture and fixtures 3 years Computer equipment and software 3 years Leasehold improvements are amortized over the shorter of the remaining term of the lease or estimated life of the asset. Internally developed software will be amortized over the estimated life of the asset, which is expected to be three to five years. Impairment of Long-Lived Assets Income Taxes Stock-Based Compensation . The expected lives of the options and employee stock purchase plan rights are based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected term at grant date. Volatility is based on historical and expected future volatility of the Company’s stock. The Company has not historically issued any dividends beyond one-time dividends declared in 2011 and 2016 and does not expect to in the future. Forfeitures are estimated at the time of the grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates. Advertising Costs Net Income (Loss) Per Share Weighted average common shares outstanding for the years ended December 31, 2016 and 2015 were as follows: Year ended December 31 2016 2015 Denominator for basic net income (loss) per share - weighted average shares 11,629,000 12,044,000 Effect of dilutive securities: Stock options, restricted stock and restricted stock units - 172,000 Denominator for diluted net income (loss) per share - weighted average shares 11,629,000 12,216,000 Due to the net loss incurred during the year ended December 31, 2016, all stock awards were anti-dilutive for the period. Options to purchase approximately 613,000 shares of common stock with a weighted average exercise price of $3.79 were outstanding at December 31, 2015 and were not included in the computation of common stock equivalents because their exercise prices were higher than the average fair market value of the common shares during the year.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Stock-Based Compensation The following table summarizes the stock-based compensation expense that was recognized in the Company’s statements of operations and comprehensive income (loss) for the years ended December 31, 2016 and 2015: Year ended December 31 2016 2015 Cost of sales $ 28,000 $ 34,000 Selling 52,000 69,000 Marketing 1,000 15,000 General and administrative 123,000 235,000 $ 204,000 $ 353,000 The Company uses the Black-Scholes option-pricing model to estimate fair value of stock-based awards with the following weighted average assumptions: 2016 2015 Stock Options: Expected life (years) 2.5 3.4 Expected volatility 41 % 45 % Dividend yield 0 % 0 % Risk-free interest rate 1.0 % 1.2 % 2016 2015 Stock Purchase Plan Options: Expected life (years) 1.0 1.0 Expected volatility 31 % 37 % Dividend yield 0 % 0 % Risk-free interest rate 0.6 % 0.3 % The Company uses the graded attribution method to recognize expense for unvested stock-based awards. The amount of stock-based compensation recognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company re-evaluates the forfeiture rate annually and adjusts it as necessary. As of December 31, 2016, there was approximately $12,000 of total unrecognized compensation costs related to the outstanding stock options, which is expected to be recognized over a weighted average period of 0.5 years. As of December 31, 2016, there was approximately $287,000 of total unrecognized compensation costs related to restricted stock and restricted stock units, which is expected to be recognized over a weighted average period of 3.1 years. Stock Options, Restricted Stock, Restricted Stock Units, and Other Stock-Based Compensation Awards In May 2015, the 2013 Plan was amended to increase the total number of shares available to a total of 1,100,000 shares. Under the terms of the 2013 Plan, as amended, the Company may grant up to 1,100,000 awards in a variety of instruments including stock options, restricted stock and restricted stock units to employees, consultants and directors generally at an exercise price at or above 100% of fair market value at the close of business on the date of grant. Stock options expire 10 years after the date of grant and generally vest over three years. The Company issues new shares of common stock when stock options are exercised.

Options exercisable at December 31, 2016 had a weighted average remaining life of 5.55 years and an aggregate intrinsic value of $74,000. The weighted average grant-date fair value of options granted during the years ended December 31, 2016 and 2015 were $0.56 and $0.94, respectively. During May and June 2016 and June 2015, equity grants were made by the Company to the Board of Directors, pursuant to the 2013 Plan in the form of shares of common stock. The total number of shares granted to the Board of Directors was 54,036 and 37,233 during the years ended December 31, 2016 and 2015, respectively. The shares were issued at a weighted average value of $2.19 per share in 2016 and $2.82 per share in 2015, based on the stock price on the date of grant, for a total value of $119,000 in 2016, of which $109,000 included in stock-based compensation expense for the year ended December 31, 2016 and $10,000 was accrued for and expensed in the year ended December 31, 2015, in addition to $105,000 in 2015, which is included in stock-based compensation. During the year ended December 31, 2016, the Company issued 100,000 shares of restricted stock under the 2013 Plan. The shares underlying the award were assigned a value of $2.33 per share, which was the closing price of our common stock on the date of grant, and is scheduled to vest over the five years following the date of grant. No restricted stock was issued during the year ended December 31, 2015. During the year ended December 31, 2016, the Company issued 21,875 performance-based restricted stock units under the 2013 Plan. Each unit represents the right to acquire one share of the Company’s common stock. The units were assigned a weighted average value of $0.85 per unit, based on market condition assumptions, and are scheduled to vest with respect to 80% of the units if the price of the Company’s common stock during the applicable measurement period exceeds a minimum performance threshold or 100% if a maximum performance threshold is exceeded. No performance-based restricted stock units were issued during the year ended December 31, 2015. During the year ended December 31, 2016, the Company issued 68,000 restricted stock units under the 2013 Plan.

The Company issued 99,000 restricted stock units during the year ended December 31, 2015. The units were assigned a value of $2.71 per share, based on the stock price on the date of the grant, and vest over two years. Restricted stock and restricted stock unit transactions during the years ended December 31, 2016 and 2015 are summarized as follows: Number of Shares Weighted average grant date fair value Unvested shares at January 1, 2015 25,000 $ 3.03 Granted 99,000 2.71 Vested (8,334 ) 3.03 Forfeited or surrendered (27,000 ) 2.89 Unvested shares at December 31, 2015 88,666 2.72 Granted 189,875 2.11 Vested (23,167 ) 2.68 Forfeited or surrendered (50,499 ) 2.72 Unvested shares at December 31, 2016 204,875 $ 2.16 Employee Stock Purchase Plan. Stock Repurchase Plans. On October 30, 2015, the Board authorized the repurchase of up to $5,000,000 of the Company’s common stock on or before October 30, 2017. The plan allows the repurchases to be made in open market or privately negotiated transactions. The plan does not obligate the Company to repurchase any particular number of shares, and may be suspended at any time at the Company’s discretion. For the years ended December 31, 2016 and December 31, 2015, the Company repurchased approximately 128,000 and 664,000 shares at a total cost of $312,000 and $1,762,000, respectively. Dividends.

The underlying assumptions the Company uses in forecasting future taxable income require significant judgment and take into account the Company’s recent performance. The change in the valuation allowance for the years ended December 31, 2016 and 2015 was $31,000 and $0, respectively. The valuation allowance as of December 31, 2016, was the result of certain capital losses that the Company does not believe are more likely than not to be realized. The Company has recorded a liability of $554,000 and $528,000 for uncertain tax positions taken in tax returns in previous years as of December 31, 2016 and 2015, respectively. This liability is reflected as Accrued Income Taxes on the Company’s Balance Sheets. The Company files income tax returns in the United States and numerous state and local tax jurisdictions. Tax years 2013 and forward are open for examination and assessment by the Internal Revenue Service. With limited exceptions, tax years prior to 2013 are no longer open in major state and local tax jurisdictions. The Company does not anticipate that the total unrecognized tax benefits will change significantly prior to December 31, 2017. A reconciliation of the beginning and ending amount of the liability for uncertain tax positions is as follows: Balance at January 1, 2015 $ 486,000 Increases due to current year positions 18,000 Increases due to interest 24,000 Balance at December 31, 2015 528,000 Decreases due to current year positions (2,000 ) Increases due to interest 28,000 Balance at December 31, 2016 $ 554,000

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Description of Business	Insignia Systems, Inc. (the “Company”) markets in-store advertising products, programs and services to retailers and consumer packaged goods manufacturers. The Company operates in a single reportable segment. The Company’s products include the Insignia Point-of-Purchase Services (POPS®) in-store marketing program, thermal sign card supplies for the Company’s Impulse Retail System, and laser printable cardstock and label supplies. In October 2014, the Company announced the introduction of a new product, The Like MachineTM. The agreement under which the Company distributes this product expires on March 31, 2017. In December 2016, the Company decided not to renew the agreement and to discontinue the sale of this product upon the expiration of the agreement. Revenue from The Like Machine was not significant in 2016 or 2015.
Revenue Recognition	Revenues are recognized by the Company when persuasive evidence of an arrangement exists, shipment has occurred, the price is fixed, and collectability is reasonably assured. The Company recognizes revenue from Insignia POPSigns and The Like Machine ratably over the period of service. The Company recognizes revenue related to equipment and sign card sales at the time the products are shipped to customers. Revenue associated with maintenance agreements is recognized ratably over the life of the contract. Revenue that has been billed and not yet earned is reflected as deferred revenue on the balance sheet. We account for taxes collected for customers on a net basis.
Cash and Cash Equivalents	The Company considers all highly liquid investments with an original maturity date of three months or less to be cash equivalents. Cash equivalents are stated at cost, which approximates fair value. At December 31, 2016, $11,103,000 was invested in an insured sweep account and $1,164,000 was invested in a money market fund. At December 31, 2015, $7,815,000 was invested in an insured cash sweep account. The balances in cash accounts, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents. Amounts held in checking accounts and in insured cash sweep accounts during the years ended December 31, 2016 and 2015 were fully insured under the Federal Deposit Insurance Corporation (“FDIC”).
Fair Value of Financial Measurements	Fair value is defined as the exit price, or the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants as of the measurement date. ASC 820-10 also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect management’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy is divided into three levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records certain financial assets and liabilities at their carrying amounts that approximate fair value, based on their short-term nature. These financial assets and liabilities included cash and cash equivalents, accounts receivable and accounts payable. At December 31, 2015, the Company had $9,490,000 of available-for-sale investments. The Company had no available-for-sale investments at December 31, 2016. Available-for-sale securities were carried at fair value with unrealized gains and losses reported as a component of shareholders’ equity as accumulated other comprehensive loss, net of tax. Fair value for available-for-sale securities was based on quoted prices for similar assets in active markets or quoted prices for identical or similar assets in markets in which there were fewer transactions (Level 2). Amortization of premiums or discounts arising at acquisition, and gains or losses on the disposition of available-for-sale securities were reported as other income. Realized gains and losses, if any, were calculated on the specific identification method and were included in other income in the statements of operations and comprehensive income (loss).
Accounts Receivable	The majority of the Company’s accounts receivable is due from companies in the consumer packaged goods industry. Credit is extended based on evaluation of a customer’s financial condition and, generally, collateral is not required. Accounts receivable are due within 30-120 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. Accounts receivable outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company’s previous loss history, the customer’s current ability to pay its obligation to the Company, and the condition of the general economy and the industry as a whole. The Company writes-off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. Changes in the Company’s allowance for doubtful accounts are as follows: December 31 2016 2015 Beginning balance $ 79,000 $ 89,000 Bad debt provision 67,000 (5,000 ) Accounts written-off (5,000 ) (5,000 ) Ending balance $ 141,000 $ 79,000
Inventories	Inventories are primarily comprised of parts and supplies for the Impulse machine, sign cards, and roll stock. Inventory is valued at the lower of cost or market using the first-in, first-out (FIFO) method, and consists of the following: December 31 2016 2015 Raw materials $ 123,000 $ 69,000 Work-in-process 27,000 4,000 Finished goods 175,000 318,000 $ 325,000 $ 391,000 In connection with the discontinued sale of The Like Machine, as of December 31, 2016, the Company deemed the value of the on-hand inventory related to The Like Machine to be impaired and recorded a $173,000 increase to the obsolescence reserve.
Property and Equipment	Property and equipment is recorded at cost. Significant additions or improvements extending asset lives are capitalized, while repairs and maintenance are charged to expense when incurred. Internally developed software is capitalized upon completion of preliminary project stage and when it is probable the project will be completed. Expenditures are capitalized for all development activities, while expenditures related to planning, training, and maintenance are expensed. Depreciation is provided in amounts sufficient to relate the cost of assets to operations over their estimated useful lives. The straight-line method of depreciation is used for financial reporting purposes and accelerated methods are used for tax purposes. Estimated useful lives of the assets are as follows: Production tooling, machinery and equipment 1 - 6 years Office furniture and fixtures 3 years Computer equipment and software 3 years Leasehold improvements are amortized over the shorter of the remaining term of the lease or estimated life of the asset. Internally developed software will be amortized over the estimated life of the asset, which is expected to be three to five years.
Impairment of Long-Lived Assets	The Company records impairment losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. Impaired assets are then recorded at their estimated fair value. There were no material impairment losses during the years ended December 31, 2016 and 2015.
Income Taxes	Income taxes are accounted for under the liability method. Deferred income taxes are provided for temporary differences between the financial reporting and tax basis of assets and liabilities. Deferred taxes are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or the entire deferred tax asset will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of the enactment. It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense (benefit).
Stock-Based Compensation	The Company measures and recognizes compensation expense for all stock-based payments at fair value. We use the Black-Scholes option pricing model to determine the weighted average fair value of options and employee stock purchase plan rights. The determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as by assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. Restricted stock units and awards are valued at the closing market price of the Company’s stock date of the grant. The expected lives of the options and employee stock purchase plan rights are based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected term at grant date. Volatility is based on historical and expected future volatility of the Company’s stock. The Company has not historically issued any dividends beyond one-time dividends declared in 2011 and 2016 and does not expect to in the future. Forfeitures are estimated at the time of the grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates.
Advertising Costs	Advertising costs are charged to operations as incurred. Advertising expenses were approximately $46,000 and $42,000 during the years ended December 31, 2016 and 2015, respectively.
Net Income (Loss) per Share	Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average shares outstanding and excludes any dilutive effects of stock options and restricted stock units. Diluted net income (loss) per share gives effect to all diluted potential common shares outstanding during the year. Weighted average common shares outstanding for the years ended December 31, 2015 and 2014 were as follows: Year ended December 31 2016 2015 Denominator for basic net income (loss) per share - weighted average shares 11,629,000 12,044,000 Effect of dilutive securities: Stock options, restricted stock and restricted stock units - 172,000 Denominator for diluted net income (loss) per share - weighted average shares 11,629,000 12,216,000 Due to the net loss incurred during the year ended December 31, 2016, all stock awards were anti-dilutive for the period. Options to purchase approximately 613,000 shares of common stock with a weighted average exercise price of $3.79 were outstanding at December 31, 2015 and were not included in the computation of common stock equivalents because their exercise prices were higher than the average fair market value of the common shares during the year.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.
New Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board ("FASB") issued guidance creating Accounting Standards Codification ("ASC") Section 606, "Revenue from Contracts with Customers." The new section will replace Section 605, "Revenue Recognition" and creates modifications to various other revenue accounting standards for specialized transactions and industries. The section is intended to conform revenue accounting principles with a concurrently issued International Financial Reporting Standards with previously differing treatment between United States practice and those of much of the rest of the world, as well as, to enhance disclosures related to disaggregated revenue information. The updated guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within that reporting period. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods, within that reporting period. We are in the process of determining the impact that the updated accounting guidance will have on our financial statements upon adoption. In February 2016, the FASB issued ASU 2016-2, Leases In March 2016, the FASB issued ASU 2016-9, Compensation - Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting
