Abstract
A system and method for matching spot colors in a PDL document with actual printed output is disclosed. A pre-press workflow application identifies spot colors in a PDL document and creates a table of potential substitute color tiles, each having color characteristics similar to the original spot color. These tiles are then printed in a “swatch page” of numerically assigned colors and reviewed by the user for potential selection over the original spot color values. A substitute color may then be selected from the swatch page and the pre-assigned numerical value for the selected color tile input into the workflow application. The PDL document is then altered to record the color change. The resulting printed document more closely matches the desired spot color and the process can be repeated for any print environment to allow for more consistent printing results and lower print job costs.
