Abstract: The application relates to a method for controlling a printing process for printing a decorative target image on a substrate, comprising providing the decorative target image to be printed in the printing process by at least one decorative parameter data set, simulating the printing process in a simulation step based on the decorative parameter data set, at least one printing process parameter data set and stored historical printing data sets, such that a digital decorative image is generated, verifying the generated digital decorative image based on the decorative target image to be printed and at least one verification criterion, and if the verification criterion is met, outputting the printing process parameter data set used in the simulation step for performing the printing process.

Abstract: A water-resistant photographic paper support comprises a base paper, coated on both sides with polyolefin, internally sized by the application of a hydrophobizing sizing agent, and surface-treated with an aqueous coating mass, which contains an anionic polyacrylamide and an oxidized starch as well as a soluble salt of an alkali metal or an alkali earth metal.

Abstract: There is described a water-resistant paper support for photographic layers with at least one coating hardened by electron beams, in which the base paper of the paper support contains at least one aluminum compound in a quantity, relative to the aluminum ion, of 1 to 12 kg/t of cellulose, preferably 3 to 6 kg/t of cellulose, and with a pH-value of the paper stuff of the base paper between 5 and 8.
