* HUDSON, N.H., May 24/PRNewswire/ -- Howtek, Inc. (AMEX: HTK) today announced that it had filed an additional claim for patent infringement


in its lawsuit against Tektronix, Inc. which was originally brought on March 24, 1993 in the United States District in New Hampshire. In an amended filing to the complaint, Howtek claims that the ink which Tektronix uses in its Phaser III PXi color printer infringes U.S. Patent No. 4,820,346 which is owned by Howtek. The original complaint claims that Tektronix is infringing Howtek patent Nos. 5,196,236 and 4,741,930 which describe a method for achieving subtractive color printing.
 Stewart Hall, Howtek's vice president general counsel, stated that "Howtek, holder of twelve ink jet patents, has invested over $25 million in developing its solid ink jet technology and will vigorously defend its proprietary interests in that technology."
 Howtek's product offering includes SCANMASTER(tm), a series of drum and flatbed scanners and COLORSCAN(R), a complete pre-press color separation and page make-up system for newspapers, publishers and graphic arts markets. Howtek was founded in 1984 by Robert Howard, who also founded Centronics Data Computer Corp. in 1969 and was co-founder of Presstek, Inc. in 1987 of which he is currently chairman and chief executive officer.
