Abstract: A printing sleeve includes a first and radially inward layer having an inner side for directly contacting the outer side of a printing cylinder, and an outer side which is radially opposite the inner side. The first and radially inward layer has a glass fiber reinforced compressible compound such that the glass fibers may absorb the forces that arise in the circumferential direction and/or in the longitudinal direction, and the compressible compound elements may absorb the pressures that arise in the radial direction. In this way, the materials which to date act separately in the base sleeve and the compressible layer are combined in one common layer in which said materials each may perform their function.

Abstract: An ink transfer medium, in particular a printing blanket, in particular a printing blanket for flexographic printing, has a cover layer for transferring an ink via a printing side and an adhesive layer for fastening the ink transfer medium to a base, in particular to a cylinder of a printing machine. The ink transfer medium is characterized by a support layer which is disposed between the cover layer and the adhesive layer, wherein the adhesive layer is disposed directly on that side of the support layer that faces away from the printing side, and wherein the support layer is a film/foil.

Abstract: The invention relates to a printing sleeve (1) comprising a first, radially inner layer (11) that has an inner side (11a) for making direct contact with the outer side of a printing cylinder (10), and an outer side (11b) which lies radially opposite said inner side (11a); as well as a second, radially outer layer (12) that has an outer side (12b) for forming a printing surface, and an inner side (12a) which lies radially opposite said outer side (12b). Said printing sleeve (1) is characterised in that the outer side (11b) of the first, radially inner layer (11) and the inner side (12a) of the second, radially outer layer (12) lie directly one against the other, and in that said first, radially inner layer (11) is designed to be able to absorb both forces occurring in the circumferential direction (U) and/or longitudinal direction (L), and pressures that arise in the radial direction (R).

Abstract: The invention is directed to a method for grinding a printing form in the area of flexographic or relief printing wherein the material to be ground is an elastomer material or an elastomer-containing material. A feed or first speed (v) is imparted to the material to be ground. The material is grindingly abraded with a grinding belt or grinding paper moving at a second speed (V) at least five times greater than the first speed (v).

Abstract: A printing form is for use in relief printing, in particular flexographic printing. The printing form is configured as a single or multilayered cylindrical layer structure having at least a first layer having a vulcanizate based on at least one elastomer. The first layer is extruded.

Abstract: A multilayered structure is for use as one of a printing blanket and a printing plate for relief printing including flexographic printing. The multilayered structure has a first layer including a vulcanizate based on at least one elastomer and at least one further layer adhesively connected to the first layer in such a manner that the first layer is peelable or strippable from the further layer.

Abstract: A metal-backed printing blanket includes the following layers: a printing layer, a metal foil and a cover layer bonded to the surface of the metal foil that faces away from the printing layer. The cover layer is irreversibly bonded to the metal foil by a chemically-curing adhesive.

Abstract: A metal-back printing blanket (2) includes a printing layer (4), a metal foil (10), a cover layer (14) which is bonded via an adhesive layer (12) to that surface of the metal foil (10) which faces away from the printing layer (4). The cover layer (14) is made of a nonwoven fabric.

Abstract: The invention relates to a multilayer sheet material (20) in the form of a printing blanket having a printing layer (21) made of a polymer material, at least one compressible layer (22, 23) and at least one reinforcing base layer (24, 25), the individual layers forming a bond with each other, characterized in that the printing layer (21) has an additional coating (27) locally bounded at at least one location of the printing layer (21) and completely preventing ink transfer at the locally bounded location, wherein the additional coating (27) is built up of at least one resin and/or at least one paint and/or at least one polymer. The invention further relates to a method for making such a multilayer sheet material (20).

Abstract: The invention is directed to a multiple-layer flat structure (1) in the form of a printing blanket or a printing plate for flexographic and letterpress printing with: a printing layer (2) which is made from a polymeric material and is provided with laser engraving; at least one compressible layer (3); and, at least one strength-support layer (4); wherein the individual layers form an adhesive connection among one another. The multiple-layer flat structure (1) according to the invention is distinguished by the fact that the polymeric material of the printing layer (2) is a vulcanizate. Advantageous materials are proposed in this regard. The printing layer (2) expediently lies directly on a compressible layer (3). The compressible layer (3) is in turn in direct contact with a strength-support layer (4).

Abstract: The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02, 18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner.
