     REGISTRATION STATEMENT ON FORM S-1; FILE NO. 333-06617

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-1 (File No. 
333-06617)(the "Registration Statement") filed by you, Raster Graphics, Inc.,
with the Securities and Exchange Commission on June 21, 1996 in connection with
the registration under the Securities Act of 1933, as amended, of 3,450,000
shares of your Common Stock (the "Shares"). The Shares include an over-allotment
option to purchase 450,000 shares granted to the Underwriters. As your counsel 
in connection with this transaction, we have examined the proceedings taken and
are familiar with the proceedings proposed to be taken by you in connection
with the sale and issuance of the Shares.

        It is our opinion that upon conclusion of the proceedings being taken
or contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
the various states where required, the Shares when issued and sold in the
manner described in the Registration Statement will be legally and validly
issued, fully paid and nonassessable.

        We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and in any amendment thereto.

                                   Very truly yours,
