Abstract
A method of creating a digital mask in situ for use in a process of making digital flexographic printing elements. The digital mask is created by laminating the negative image that is the by-product of a thermal proofer to a photosensitive printing plate. Thereafter, the photosensitive printing element can be imaged, exposed, and developed in the usual manner.
Claims8
A method of creating a digital mask for imaging a photosensitive printing element, comprising the steps of:
- a) providing a donor element and a receptor element in a thermal proofer, wherein the donor element is capable of transferring material to the receptor element to create an image on the receptor element while retaining a negative of the image on the donor element;
- b) outputting a desired image to the thermal proofer;
- c) transferring material from the donor element to the receptor element to create the image;
- d) separating the donor element from the receptor element and retaining the donor element;
- and
- e) laminating the donor element containing the negative image therein to a top surface of the photosensitive printing element.
