Definitions
- the present invention relates to rubber-coated ink transfer rollers, processes for their preparation and their use.
- Ink units in offset printing presses are often equipped with film inking units.
- the ink feed takes place continuously from the ink fountain via the ink ductor to the adjacent film roller.
- Between the ink fountain roller and the film roller is a gap of about 0.04 to 0.10 mm.
- a rubberized (rubber-coated) ink transfer roller in the hardness range of 20-80 Shore A is employed on the film roller.
- Rubberized ink rollers in offset printing generally have a smooth surface with average surface roughness Rz of ⁇ 20 microns, typically ⁇ 10 microns.
- EP 0 662 394 A1 relates to a pressure roller with grooves, by means of which a diamond pattern is formed.
- the roller described therein is employed in an inking unit to a ductor and corresponds to a film roller.
- DE 71 41 940 relates to a fountain roller for inking units.
- the fountain roller has crosswise depressions so that diamond-shaped surfaces are created.
- Object of the present invention was to avoid the problems mentioned, in particular to reduce the problem of paint spraying or color fogging.
- the surface of the rubber-coated ink transfer roller has an average roughness depth Rz of 30 to 80 ⁇ m and a maximum roughness depth R max of 40 to 120 ⁇ m.
- the rubber-coated ink transfer roller has a free specific volume Vi between 0.001 and 0.1 mm 3 / mm 2 .
- the rubber-coated ink transfer roller has a free specific volume V 2 between 0.02 and 1.5 mm 3 / mm 2 .
- the roughness depths are measured with a roughness measuring instrument using the stylus method (Perthometer) according to DIN EN ISO 4287.
- the average surface roughness is in the range of 40 to 60 microns and / or the maximum surface roughness between 60 and 100 microns.
- a suitable method for producing such ink transfer rollers is based on the processing of a rubber-coated roller with a hedgehog cutter. As a result, the uppermost rubber layer is removed, and it remains an irregular structure, which partially has a scale-like appearance (see Figure 1).
- the structures according to the invention are rough and uneven.
- the structure is scaly and random. It contains no superordinate structures such as grooves or diamonds.
- Suitable rubber materials for the ink transfer roller are acrylonitrile-butadiene rubber (NBR), hydrogenated acrylonitrile-butadiene rubber (HNBR), chloroprene rubber. rubber (CR), epichlorohydrin rubber (ECO), styrene-butadiene rubber (SBR), as well as copolymers and blends.
- the ink transfer roller has a core of a dimensionally stable material, for example made of steel, aluminum or carbon fiber reinforced plastics (CFRP) or glass fiber reinforced plastics (GRP).
- CFRP carbon fiber reinforced plastics
- GFP glass fiber reinforced plastics
- the free volumes Vi and V 2 can be measured with an RFT MicroProf ® with chromatic sensor (CWL).
- CWL chromatic sensor
- the samples are illuminated with focused white light.
- the sensor measures the wavelength-dependent (chromatic) distribution of the reflected light and uses this to determine the absolute height information.
- a surface topography is obtained as a quantitatively present data field so that any distances, heights and angles, roughnesses and undulations as well as flatnesses in images can be measured after the measurement.
- the volumes Vi and V 2 which can be calculated from the topographical recordings are suitable for characterizing the surfaces.
- the filling volume Vi is the filling volume from the lowest measuring point to the height of the middle level, which in this case is assigned to the height value 0.
- the filling volume V 2 is determined from the lowest to the highest measuring point within a topographic image.
- FIG. 2 schematically shows the differences between the filling volumes Vi and V 2 .
- the calculated volumes are presented by means of the gray area.
- the subject matter is also the use of a rubber-coated roller with an average roughness R z of 30 to 80 microns and a maximum surface roughness R ma ⁇ from 40 to 120 microns as ink transfer roller, especially in offset printing process.
- R z average roughness of 30 to 80 microns
- R ma ⁇ maximum surface roughness from 40 to 120 microns
- Another embodiment of the invention is an inking unit containing the ink transfer roller according to the invention.
- FIG. 1 shows a topographic image of the surface with a chromatic sensor (CWL).
- CWL chromatic sensor
- Figure 2 shows the difference between the free volumes Vi (left) and V 2 (right).
- FIG. 3 shows schematically parts of an inking unit. This comprises a Farbduk- gate 1, a film roller 2 and a ink transfer roller 3.
- a fountain roller 5 and a paint box 6 with a color 7 is additionally shown.
- a paint transfer roller having a diameter of 105 mm and a length of 1035 mm with a core of steel and an NBR coating was processed with a single grit rubber hog wheel. For this purpose, the following processing conditions were met.
- the roughness depth was measured on the roller thus obtained.
- the R max value was 80 ⁇ m, an average roughness R z was about 52 ⁇ m.
- Vi was 0.012 mm 3 / mm 2 , V 2 was 0.191 mm 3 / mm 2 . It is important that feed marks are avoided by a uniform processing.
