Abstract
A method for manufacturing a lithographic printing plate precursor includes the steps of providing a support as a web, coating an image recording layer on the front side of the support, and depositing a back layer on the back side of the support using a deposition technique which is capable of depositing the back layer according to a predefined image. The method enables stacking and recutting of lithographic printing plate precursors without the need for interleafs.
Claims16
A method for manufacturing a lithographic printing plate precursor, the method comprising the steps of:
- providing a support as a web, the support including a front side and a back side;
- coating an image recording layer on the front side of the support;
- and
- depositing a non-continuous back layer on the back side of the support according to a predefined image the predefined image including a cutting scheme defining predefined cutting edges of the lithographic printing plate precursor;
- and
- slicing and cutting the web along the predefined cutting edges;
- wherein the non-continuous back layer has a lower average surface coverage in sections within 1 cm of the predefined cutting edges than in neighboring sections of the web.
