PURPOSE:To obtain the process for production of the dampening waterless photosensitive planographic printing plate which is good in reproducibility of small dots in spite of an increase of the thickness of a silicone layer, does not contaminate the hands, clothing, automatic developing machine, etc., with a dyeing color and can form visualized images having stable image densities. CONSTITUTION:This process for production of the dampening waterless photosensitive planographic printing plate consists in exposing and developing the printing plate, then superposing the printing plate and a laminate having a layer contg. color materials or the precursors of the color materials on a base in such a manner that the laminate and these layer contg. the color materials or the precursors of the color materials, heating and/or pressurizing the plate and the laminate, and transferring and shifting the color materials or the precursors of the color materials in the line image part of the plate surface, thereby obtaining visualized images. |
