PURPOSE:To obtain the processing method for the dampening waterless photosensitive planographic printing plate which has an excellent visible image characteristic after development, does not contaminate the printing plate, hands, fingers and automatic developing machine, etc., and allows the easy maintenance, management and handling of the automatic developing machine. CONSTITUTION:This processing method for dampening waterless photosensitive planographic printing plate contg. at least diazo compds., coupling agents and color developing assistants consists in incorporating at least one kind of the diazo compds., coupling agents and color developing assistants into microcapsules and developing the colors of image parts by heating and/or pressurizing these during and/or after the development of the dampening waterless photosensitive planographic printing plate. |
