摘要：
Lithographic printing plates can be prepared with enhanced contrast between the image and background by coloring the imaged or exposed regions using a coloring fluid containing a water-insoluble colorant (dye or pigment) and an organic solvent that swells the imaged regions sufficiently for the colorant to be embedded or diffused therein.
