Claim:
A halftone screening method for Dry Offset printing, comprising the steps of: converting an original customer-supplied file into a desired continuous tone color space, the customer-supplied file including continuous tone images and a page geometry by accomplishing the following steps: converting the file image and page geometry from Cyan/Magenta/Yellow/Black (CMYK) to Red/Green/Blue (RGB) color space, converting the RGB back to CMYK with maximum ink density and no Under Color Removal (UCR), converting the RGB to CMYK again, but with maximum Gray Component Replacement (GCR), and combining the colors from the second and third conversion steps; subjecting the continuous tone images only to a screening process; subjecting both the continuous tone images and the page geometry to a screening process; combining the screening applied to just the continuous tone images and the screening applied to both the continuous tone images and the page geometry; constructing a final file, using the combined screenings, wherein, the final file is a useful form to construct printing plates.
