Embodiment Construction
[0045] In the pre-press workflow, RIP software or digital workflow software can generate PPF files or TIFF files from imposition files in PDF, EPS or PS formats, in order to calculate the graphics and text of each ink area more conveniently and accurately The coverage, the resolution of the generated PPF file or TIFF file should be set according to the characteristics of the offset printing machine, the purpose is to make the number of pixels per raster an integer. For example, Roland 700 offset printing machine is used in this example. The resolution of PPF file or TIFF file is 50.8PPI. If a 1-TIFF file is generated, the resolution is 300PPI, and the number of screening lines is 30 lines / inch.
[0046] Use the input interface of the control computer to read in the PPF file or TIFF file generated before printing, input the width value of an ink area from the keyboard, take the centerline of the width direction of the digital image as the reference, and take the width of an ink ...
