摘要：
A color contrast image in imaged lithographic printing precursors can be obtained by contacting the imaged precursor with a coloration solution containing a colorless form of a photochromic compound. Residual amounts of this compound attached to the oleophilic surface of the imaged precursor can be changed to its colored form when exposed to UV light. The coloration solution can be an alkaline or acidic developer or an alkaline or acidic solution used separately after development. The coloration solution can also be a gum solution.
