Appl. No.:

11/051277

Printing Research, Inc. - Dallas TX

International Classification:

F26B 3/34

US Classification:

34268, 34269

Abstract:

A system for curing printing plates with controlled radiant energy sources. A conveyor moves a printing plate through a chamber having energy radiators above and below the conveyor. Power to the radiators is controlled for each radiator or to groups of radiators defining radiation zones. Curing time may be controlled by adjusting power to the radiators and adjusting the conveyor speed. Sensors detect a plate as it enters and exits the chamber. Heat sensors may detect chamber or plate temperatures. A color sensor may detect plate color as an indicator of degree of curing. A computer system stores curing scenarios and uses the sensor signals and operator inputs to control power to the radiators and conveyor speed to provide uniform curing of the plate.

International Classification:

F26B 3/34

US Classification:

34245

Abstract:

A printing plate curing system includes a color sensor that measures at least one color value of a printing plate. The color value is used to control a parameter of a curing system, such as energy output or conveyor speed. Multiple color sensors may be used to measure color values of a printing plate before and after imaging, developing and curing. Each sensor may measure multiple color values. The measure values may be used to control an imager as well as a curing system.
