Abstract:
The Digital Prepress System is a workflow process that can be used for preparation and design artwork using different software and hardware as selected by the user and job requirements. The process frequently finds problems in data transferring, fonts, loss of images data, separation, etc. Identifying these problems will enable them to be corrected quickly and efficiently saving the user valuable personal and computer time. The purpose of this research is to design and develop tools for evaluating digital prepress systems designed to address the problems of tone reproduction, font, spot color, trapping, hairline, gradation, UCR and GCR etc, using graphic and application softwares such as Adobe Photoshop 7.0, Adobe Illustrator 10.0, Macromadia Freehand 10.0 and CorelDraw 10.0 etc. in various formats and then applying them with such software as Adobe Pagemaker 7.0, MS Word 2000, MS Excel 2000, and MS Powerpoint 2000. The identical files will then be taken to two different prepress service centers. Each center will output film separation through an imagesetter and make a proof. The two proofs will then be evaluated for quality and differences indentified. This test will enable us to consider the problems and know the limitations of systems used by the two different service centers. This tool can solve many of the communication problems between the printing firm and the printing firm.
