A pigment composition containing one or more luster pigments, a phosphate derivative and spherical particles having a particle size of 0.05-150 .mu.m useful, especially, in printing inks.

Pigment preparation and its use

The present invention relates to a low-viscosity offset printing ink which essentially comprises a binder, additives and 5-40% by weight of pearlescent pigments and has an improved transfer behavior for pearlescent pigments.

Offset printing ink

The gap (15) formed between the end portions (5) of a gravure printing plate (3) which is anchored in a groove (2) of a printing cylinder (1) on which the plate is mounted is covered with a sheet (6) which overlaps the end portions. The gap cavity (9) thus formed is then filled with a thermoplastic and/or hardenable material and when this has hardened the cover is removed.

Process and arrangement for sealing the gap between the ends of a

A process for underlaying flat-bed steel rule dies prior to producing sheet-like geometrical cut blanks, preferably from multi-blank sheets, in which varying tolerances, in the punching and cutting direction, of the steel rule cutters held in a rigid plate are compensated by a sheet, corresponding to the area of the sheet being cut, placed on the back of the steel rule cutter plate and consisting of a flowable hardenable plastic, the upper and lower platen being moved together so as to close the die and the sheet of plastic, bearing the relief formed thereon, then being solidified by an after-treatment.
