Abstract
A method of preparing a lithographic printing plate includes the steps printing a liquid on a lithographic support to form a printing area which corresponds to a raster image, wherein the raster image includes a section which has a tone-value from 90% to 100%, and the jetted liquid droplets for this section, on a corresponding part from the printing area on the lithographic support, are contactless with each other.
Claims16
A method of preparing a lithographic printing plate comprising the steps of:
- jetting liquid droplets onto a lithographic support to define a printing area that corresponds to a raster image;
- and
- curing the jetted liquid droplets on the lithographic support to define a plurality of cured drops as the printing area;
- wherein
- the raster image includes a section having a tone-value from 90% to 100%;
- after the step of curing, the jetted liquid droplets in a portion of the printing area that corresponds to the section having the tone-value from 90% to 100% do not contact each other at a top of the jetted liquid droplets;
- and
- when the section of the raster image has a tone-value of 100%, the portion of the printing area has a tone-value of no more than 98%.

A lithographic printing plate comprising:
- a lithographic support;
- and
- an image-wise distribution of cured ink accepting drops on the lithographic support that represent a raster image;
- wherein
- a portion of the image-wise distribution of ink accepting drops corresponds to a section of the raster image having a tone-value from 90% to 100%;
- the cured ink accepting drops do not contact each other;
- and
- each of the cured ink accepting drops has a height, corresponding to a maximum thickness of the cured ink accepting drop, between 4.0 μm and 50.0 μm.
