Abstract: A method and an apparatus for transferring ink, varnish or adhesive during laminating or printing, particularly flexographic printing, operates with a roller in the form of a smooth roller for transferring the material from the smooth roller to a substrate. A plurality of spray modules arranged next to each other and individually controllable is provided for spraying the material onto one or more cylindrical portions of the smooth roller. A doctor blade is arranged following the point of transfer of the material as seen in the direction of rotation of the smooth roller.

Abstract: A method of manufacturing a flexographic printing plate having a base (polyester foil) and a soft caoutchouc mass which is enriched with photo-initiators (photo-polymer) and is arranged on the base, wherein a film with the image to be printed is fastened with precise fit on a free surface portion of the caoutchouc mass. The method includes removing the caoutchouc mass at the edges of the base intended for fastening. The base is provided with register holes in the areas of the exposed edges of the base and the base is placed with the register holes on register pins of an assembly rail. Spacer pieces are placed on the exposed edges of the base, wherein the thickness of the spacer pieces corresponds to the thickness of the removed caoutchouc mass. A film having corresponding register holes is placed on the register pins. Finally, exposure to light, washing and assembly in the printing machine are carried out.

Abstract: The invention relates to a method of mounting printing blocks on form cylinders of a flexographic printing machine for multicolor printing in correct positions determined by a mounting pattern, which is secured to a mounting cylinder or mounting table. Two television cameras are directed to two spaced apart points of the mounting pattern, two television cameras are directed to two spaced apart points of the printing block carried by the form cylinder. Said television cameras are disposed in exactly fixed and mutually corresponding positions relative to the mounting cylinder or mounting table and relative to each form cylinder, when the same is in mounting position. The two images of corresponding points of the mounting pattern and of the printing block are displayed under the control of a mixer by a television screen at the same time. The printing block is initially slidably mounted on the form cylinder and is adjusted until the images displayed on the television screen coincide.
