TLDR
In this paper, a method of reducing printing artifacts in a printing apparatus including a plurality of printing plates, each of which is produced by successive scans of an array of imaging devices wherein the printing artifacts are caused by defective operation of one or more of the imaging devices was proposed.
Abstract
A method of reducing printing artifacts in a printing apparatus including a plurality of printing plates, each of which is produced by successive scans of an array of imaging devices wherein the printing artifacts are caused by defective operation of one or more of the imaging devices Printing artifacts are visually minimized by staggering the imaging devices used to produce separation plates By staggering the imaging devices, the distance between artifacts can be reduced thereby causing the artifact reproduced in the final composite image to be less accentuated

Method and apparatus for correcting and adjusting digital image output

TL;DR: In this paper, the authors proposed a method to compensate for imprecise device orientation and seam artifacts by starting imaging with the device having the greatest offset from proper orientation, and repeating at least one imaging swath to produce intentional transverse overlap between adjacent swaths.

Method of imaging an electrophotographic member and apparatus for carrying out the method

TL;DR: In this paper, a digital plate maker system was proposed to receive graphics and text data and selectively discharge incremental areas of a charged electrophotographic member to form thereon the latent images represented by the graphics, the imaged member thereafter being toned and output from the system.

Exposure controlled imaging system

TL;DR: In this paper, a rotary encoder is used to produce a fixed number of signal pulses per revolution, which are then multiplied by conventional phase-locked loop technology to generate a large number of clock pulses.
