Abstract
A system and method for generating a master screen for a silk screen imaging process. Photo activated emulsion is applied to a printing screen and the emulsion is exposed according to a digitized pattern using a light emitting diode (LED) source. The LED source in one embodiment is an array of UV emitting devices which scans the printing screen in a line by line basis.
Claims11
A method of producing a digitized image on a printing screen comprising the steps of:
- coating the printing screen with a photo activated emulsion;
- exposing the emulsion in accordance with a digitized image utilizing a LED source to thereby selectively activate the emulsion, such that the LED source alone defines the location of the activated emulsion which corresponds to a pixel of the digitized image;
- and
- treating the screen so as to remove inactivated emulsion.
A system for generating a master screen containing an image for screen printing comprising:
- a coating unit for applying a photo activated emulsion to a printing screen;
- a computer to screen assembly for digitizing an image to be created on the screen;
- a LED source to receive the digitized image and to expose the emulsion in accordance with the digitized image, the LED source alone defining the location of emulsion to be exposed;
- and
- a developer unit to remove unexposed emulsion from the screen.
