Abstract: Device for determining information which is indicative for a particle size and/or a particle shape of particles in a sample, wherein the device comprises an electromagnetic radiation source for generating electromagnetic primary radiation, an electromagnetic radiation detector for detecting electromagnetic secondary radiation which is generated by an interaction of the electromagnetic primary radiation with the sample, and a determination unit which is adapted for determining the information which is indicative for the particle size and/or the particle shape based on the detected electromagnetic secondary radiation, wherein the determination unit is adapted for selectively determining the information firstly by means of an identification and a size determination and/or a shape determination of the particles on a detector image which is generated from the electromagnetic secondary radiation, and/or for determining the information secondly from temporal changes of the electromagnetic secondary radiation between

Abstract: Disclosed is a printing sheet for offset printing, comprising at least one image receiving coating and optionally one or several pre-coatings beneath said image receiving coating, said coatings comprising a pigment part, a binder part, and optionally additives, wherein the pigment part essentially consists of one or a mixture of fine particulate pigments selected from the group of carbonate, kaolin, solid or vacuolated polymer pigment, wherein said binder part comprises waterglass.
