ABSTRACT:
In accordance with the present invention, there are provided methods for producing printing plates comprising rapid, efficient drying of solvent-containing resin compositions of the printing plates and apparatus useful therefor. Printing plates processed employing invention methods and apparatus are ready for use in printing applications in a relatively short period of time, especially compared to the time required for conventional convection drying. Moreover, printing plates processed according to the present invention method and apparatus are not subjected to excessive levels of heat, as is frequently the case with conventional convection drying. Excessive heating tends to be detrimental to the performance properties of the polymeric resin. In a particular aspect of the present invention, there are provided novel compositions which, upon drying according to the methods described herein, undergo a color change, thereby indicating when the drying process is substantially complete. When used for the production of printing plates, invention compositions provide finished printing plates which display a readily observed contrast between the floor and image portions thereof.
