Definitions
- the present invention relates to a roller in the dampening unit, such as wet rubbing roller, wet transfer roller or dampening roller and their use in a dampening unit.
- Offset printing is an indirect printing process used in newspaper, magazine and catalog printing.
- a printing plate is created, typically a thin aluminum plate. This is clamped on a plate cylinder and is in the printing machine with dyeing and dampening in combination. Lipophilic areas of the printing form accept ink while hydrophilic areas remain colorless.
- the ink is transferred to the blanket mounted on a blanket cylinder or offset cylinder.
- the blanket cylinder then transfers the ink to the medium to be printed using a counter-pressure cylinder or another blanket cylinder.
- dampening solution water or aqueous-alcoholic mixtures
- enough ink must be transferred to provide the lipophilic areas with ink.
- Typical dampening units contain one or more rollers, often with soft surface, eg with an elastomeric coating, in contact with one or more hard rollers or other elastomer-related rollers.
- a soft dampening roller is in direct connection with the dampening solution supply. She "draws” dampening solution from the supply and transfers it to a hard roller. The hard roller transfers the dampening solution film to the dampening roller.
- the hard roller is referred to as dampening drive roller, as wet transfer roller or as a wet roller.
- the wet-type dipping roller is a hard roller which first transfers the dampening solution to a soft roller (wet transfer roller or dampening roller), which then transfers it to a hard dampening roller or wet transfer roller, which finally transfers to the dampening roller.
- dampening units there are further rollers, e.g. Rider rollers, which serve to smooth the dampening solution film or bridge rollers, which make contact between dyeing and dampening unit.
- Rider rollers e.g. Rider rollers, which serve to smooth the dampening solution film or bridge rollers, which make contact between dyeing and dampening unit.
- rollers are hard rollers, i. Rollers without elastomer cover.
- DE-AS-1257170 describes processes for the hydrophilization of dampening rollers by producing a coating containing a vinylsilane.
- the outer layer of the roll is formed by a silane.
- DE60120444T2 discloses dummy plates which are roughened and anodically oxidized aluminum plates. Such plates are mounted there on rollers where no ink is to be transferred to the web to be printed.
- the dampening roller which is in contact with the printing form, is wetted during operation with printing ink or a printing ink emulsion. It then transmits this successively backwards to the other rollers in the dampening unit, both on the wet dipping or Feuchtdosierwalze and on the dampening roller or Feuchtübertragswalze, so that it can even come to contamination of the dampening solution in the end.
- the transfer of the paint over time leads to color build-up on the surfaces of the dampening rollers and impairment of the printing process. As a rule, this will stop the printing process and require cleaning.
- the object can be achieved by a roller in the dampening unit, in particular dampening drive roller, wet transfer roller or dampening roller with a core and an outer layer, wherein the outer layer is selected from
- Alumina obtainable by plasma chemical anodic oxidation and combinations thereof.
- the rolls according to the invention show a reduced ink residue splitting, improved and more uniform dampening solution transfer and / or easier washability.
- a roller which has an outer layer which is an aluminum hard oxoxide or a layer of chemical nickel or an aluminum oxide layer obtainable by plasma-chemical anodic oxidation is used as a hard roller in the dampening unit, in particular dampening roller, dampening roller or wet transfer roller.
- Hard oxoates of aluminum are known to the person skilled in the art. They are obtained by anodizing in a cold, acidic electrolyte. The electric current forms a protective aluminum oxide layer on the surface.
- aluminum and aluminum alloys can be used as starting material.
- a roll is used in which the entire roll (monolithic) is made of aluminum.
- the roll includes a core of another material, such as a steel core, a carbon fiber or glass fiber core, or the like, and an outer shell of aluminum that is hard-anodized.
- PTFE polytetrafluoroethylene
- silicon carbide particles are incorporated into the outer layer during production of the anodized material.
- Chemical nickel is a process in which electroless nickel is deposited from a solution of nickel ions and a reducing agent (typically hypophosphite). The method of depositing nickel layers on surfaces is basically known to the person skilled in the art.
- a core selected from steel cores, aluminum cores and carbon fiber cores is used. It is also possible in this case that in the outer layer of PTFE, other fluorine-containing polymer or Siliziumcarbidpitate be stored.
- phosphorus is also typically incorporated into the layer.
- Another suitable outer layer is obtained by a plasma-chemical coating.
- a workpiece with an external power source can be connected as the anode.
- oxygen plasma discharges on the workpiece surface, melts it, and forms two layers of oxide ceramics, which mainly consist of corundum and boehmite; see also EP 0 545 230.
- further particles for example fluoropolymers
- further particles can also be included in these layers.
- the preferred layer thickness is 5 to 200, more preferably 20 to 100 ⁇ m, preferably 30 to 60 ⁇ m.
- the aluminum hardoxates a roughness of the surface of Rz 0.1 to 100, preferably Rz 0.5 to 8 microns is particularly suitable.
- the preferred layer thickness is 5 to 200, more preferably 20 to 100 ⁇ m, preferably 30 to 60 ⁇ m.
- the aluminum oxides (corundum, boehmite) is a roughness of Surface of Ra 0.05 to 20.0 preferably Ra 0.1 to 2.0 microns particularly suitable.
- the typical thickness is 2 to 40 ⁇ m, preferably 10 to 20 ⁇ m.
- a roughness of Rz 0.1 to 100, preferably Rz 0.5 to 8 microns is particularly suitable.
- Another embodiment of the invention is a roll according to the invention, as described above, in which a PTFE or fluorine-containing polymer layer is additionally applied, i. a PTFE or other fluorine-containing polymers are not incorporated in the layer, but form a separate layer.
- the invention also provides a dampening unit comprising at least one roller according to the invention and the use of the roller according to the invention as a roller, in particular dampening drive roller or wet transfer roller in a dampening unit.
- the rolls according to the invention exhibit good wet transfer rates with a reduction in color cleavage.
- FIG. 1 shows schematically the structure of a four-roll dampening unit.
- the wet dipping roller (5b) is a hard roller, which first transfers the dampening solution to a soft roller (6), which then transfers it to a hard dampening roller, dampening roller or wet transfer roller (4), which transfers to the dampening roller (3) , which finally applies to the plate cylinder (1).
- the plate cylinder is also in connection with the inking rollers (2).
- FIG. 2 shows schematically the structure of a three-roll dampening unit.
- a soft wet dipping roller (5a) is in direct connection with the dampening solution supply. It "draws” fountain solution from the supply and transfers it to a hard dampening roller or wet transfer roller (4).
