A study using a high-addressability inkjet proofer to produce AM halftone proofs matching Kodak Approval in color, screening, and subject moire.

摘要

An investigation of the feasibility of using a high-addressability inkjet printer as an alternative to the traditional proofing systems, such as Kodak Approval, was completed. The inkjet proofs must match the press sheet in terms of color, screening, screen angle, screen ruling, and screen dot size. The relatively low cost per print and the ability to incorporate color management makes inkjet technology a potential candidate also for use as a proofer for these requirements.Existing software and patents on halftone inkjet proofing were analyzed. A test form was designed to test the proofing models for screening, screen angle, and screen ruling observed in the proofs. Several workflow models were developed to generate proofs that matched the press sheet in color and moire. Solutions for the encountered problems were tested until, finally, an optimized model was obtained that was capable of generating halftone inkjet proofs matching the press sheet visually in terms of color and moire.This model is simple, cost effective and does not require any special software. However it is limited by the constraints of file size of Photoshop.
