Abstract: A water-based primer composition comprising an porous submicron silica dispersion, preferably in an amount from 10 to 30 wt.-% based on the weight of the entire composition, starch, preferably in an amount from 10 to 30 wt.-% based on the weight of the entire composition, and at least one component selected from the group consisting of a further polysaccharide, a hemicellulose, lignin, a styrene-acrylic emulsion, a polyvinylacetate and a sulfopolyester. Further, use of the composition for preparing a primer layer on a substrate, to a method of printing on a substrate, comprising the steps of preparing a primer layer on at least a part of one surface of the substrate using the composition, and printing on the primer layer using a liquid toner, as well as to an article manufactured with the method is disclosed.

Abstract: A printing method comprising the steps of providing, in relation to data of a print job to be carried out, at least one prediction for print data for at least one selection of print parameters using at least one set of sample print data (S107). At least one print parameter is optionally adjusted to provide a prediction which comes sufficiently close to the data of the print job (B109). A software product for performing the method is also disclosed, and the use of the software product for determining printing parameters for a printing method.

Abstract: The present invention is related to a printing ink, in particular flexographic printing ink, or an overprint varnish, comprising a nitrated lignin as at least one binder component, to a process for preparing the same as well as to the use of a nitrated lignin as a binder component in a printing ink, in particular a flexographic printing ink, or an overprint varnish.

Abstract: The present invention is related to a UV-curable printing ink comprising a binder system consisting of at least one reactive diluent and at least one polyurethane resin which is inert to said diluent, wherein said ink is solvent-less and said binder system has a viscosity in the range of 200-400 Poises, preferably 250-300 Poises, at 30° C. and a shear rate between 40.000 s?1 and 70.000 s?1, as measured with a Laray viscometer.

Abstract: The present invention is related to a radiation curable binder, comprising the reaction product of a polyisocyanate having 3 free isocyanate moieties with an acrylate having isocyanate-reactive groups and a component selected from the group consisting of a C12-C22 carboxylic acid having one isocyanate-reactive group or a C12-C22 fatty alcohol. The present invention is furthermore related to a radiation curable printing ink, comprising said binder, at least one diluent, at least one pigment, and optionally additives, as well as to a process of preparing said radiation curable binder. Said binder or said printing ink can be used in offset printing or letterpress printing.

Abstract: The present invention is related to novel photoinitiators, in particular to photoinitiators comprising amino groups within the molecule.
