Definitions
- the invention relates to an aluminum alloy for the production of lithographic printing plate supports and to an aluminum strip produced from the aluminum alloy, to a method for producing the aluminum strip and to its use for the production of lithographic printing plate supports.
- Aluminum strips for the production of lithographic printing plate carriers must have a very high quality and are therefore subject to constant further development.
- the aluminum strip has to live up to a complex property profile.
- the aluminum strip is subjected to an electrochemical roughening, which must ensure a structureless appearance without streaking effects at the highest processing speed.
- the roughened structure of the aluminum strip has the task that photosensitive layers, which are subsequently exposed, can be permanently applied to the printing plate support.
- the photographic layers are baked at temperatures of 220 ° C to 300 ° C for a period of 3 to 10 minutes. Typical combinations of bake times and temperatures are for example 240 ° C for 10 minutes or 280 ° C for 4 minutes.
- the printing plate support must continue to be easy to handle, to allow a clamping of the printing plate support in the printing device.
- the softening of the pressure plate carrier after the Burning in should therefore not be too strong. Although it can be achieved by the highest possible tensile strength prior to baking, that the tensile strength after firing is sufficiently high.
- the straightening of the aluminum strip ie the elimination of a "coil set" of the aluminum strip prior to processing to the printing plate support is made difficult by a high tensile strength before baking.
- increasingly printing presses are used with the largest possible printing surfaces, so that the printing plate support no longer need to be clamped longitudinally to the rolling direction but transverse to the rolling direction in order to provide oversized printing widths.

It discloses an aluminum alloy having an Si content of up to 0.5 wt.%, an Fe content of up to 0.5 wt.%, an Mg content of 0.05 to 0.50 wt Mn content of 0.05 to 1.0 wt%, a Ti content of 0.001 to 0.1 wt%, B content of 0.0001 to 0.02 wt% , a Cu content of up to 0.3 wt .-%, a Cr content of up to 0.3 wt .-% and a Zr content of 0.001 to 0.1 wt .-%.
- the EP 1 293 579 A2 describes a printing plate support, which is made of an aluminum alloy. It discloses an aluminum alloy having an Si content of up to 0.5 wt.%, An Fe content of up to 1.0 wt.%, A Mg content of 0.1 to 1.5 wt. -%, an Mn content of 0.1 to 1.5 wt .-% and a Cu content of up to 0.2 wt .-%.

- the Si content according to the invention ensures that a high number of depressions which are sufficiently deep are produced in order to ensure optimum absorption of the photosensitive paint.
- Copper should be limited to avoid inhomogeneous structures when roughening. Titanium, which is introduced into the aluminum alloy for grain refining of the melt, leads to roughening problems at higher levels. The contents of zinc and chromium negatively influence the roughening result and should therefore be limited.

Since the aluminum strip according to the invention has a very good hot strength, it is possible by conventional process parameters to set the tensile strength values before the baking process in an ideal processing range, for example to perform the correction of a "coil set" and at the same time excellent handling and stability when used in oversized printing devices to enable.
- the object indicated above is also achieved by the use of the aluminum strip according to the invention for the production of lithographic printing plate supports according to a third teaching of the present invention.

- the intermediate annealing if an intermediate annealing is carried out, takes place in such a way that a desired final strength of the aluminum strip in the hard-rolling state is set by the subsequent cold-rolling process to final thickness.
- an intermediate annealing is carried out at an intermediate thickness of 0.5 to 2.8 mm, wherein the intermediate annealing takes place in a coil or in a continuous furnace at a temperature of 230 ° C to 470 ° C.
