Title: Screen and its production
Inventor: MASUDA TOSHIROU
IPC: G03F5/12
Filed: 1981-08-24
Abstract: PURPOSE:To eliminate a moire to be generated on a gravure screen, by using a pattern including a combination of an irregularly folded lines and smooth curved lines or irregularly and curved smooth lines. CONSTITUTION:The intersections (e.g., A-F) of a pattern containing 2-dimensional regular squares adjacent to each other are shifted at random (e.g., average shift distance: about 1/4 length of a side of a square, standard deviation: about 1/8 length of a side of a square; shift direction: all angles around intersections). Then the obtained points A'-F' are connected in correspondence to the forming segments of lines of the original square to obtain a pattern containing folded lines. Using this pattern, a gravure screen is formed. Each segment of line of a pattern including irregular folded lines can be converted into a segment which is approximated with a smooth curved line.

Abstract: PURPOSE:To obtain a reproduced picture image with high quality even if the resolution of an input device is different from the resolution of an output device by sectioning a binary-coded data subjected to dither processing into the unit of prescribed blocks and using a reference table to attain other arrangement. CONSTITUTION:An original picture image subject to raster scanning in an input device is subject to dither processing by a dither matrix and converted into a binary-coded picture and transmitted to a 2-line buffer memory 11 from an input terminal 10, fetched in a register 12 in the unit of 2X2 blocks and becomes input address information to a ROM13 written in the reference table. On the other hand, a horizontal synchronizing signal H-SYNC16 transmitted from the printer side is inputted to an address information counter 15 to designate to which line of the threshold value matrix the scanning line of the printer corresponds. The ROM13 outputs information (4-bit's share) for one line's share of a 4X4 matrix in parallel as an output data and the result is outputted from an output terminal 17. Thus, since the data is converted at each block, the memory capacity is less.
