Definitions
- the invention relates to an aluminum offset strip with a predominantly globulitically recrystallized and subsequently cold-deformed structure.
- Rolled strips and sheets made of aluminum or aluminum alloys are used in the thickness range from 0.1 to 0.5 mm to produce offset printing plates.
- the aluminum strip is provided with a light-sensitive photo layer, which is transformed by the action of light in such a way that it is insoluble for the developers used.
- a light-sensitive photo layer which is transformed by the action of light in such a way that it is insoluble for the developers used.
- an uncoated aluminum surface is present in the unexposed areas, which has hydrophilic properties.
- the rolled surface must be roughened mechanically or electrochemically or chemically to better anchor the light-sensitive layer.
- this roughening should be as homogeneous and fine-celled as possible.
- the object of the present invention is to further improve the strength and elongation values, in particular the thermal stability and rigidity, in the case of an offset tape of the type mentioned at the outset, the suitability of the surface for the subsequent electrochemical roughening being retained and a simplified method for producing such offset tapes to provide.
- the invention therefore aims at an Al offset tape with a predominantly globulitically recrystallized and then cold-deformed structure with a clearly fine grain structure and a strongly consolidated core area.
- the structure chosen means that the requirements for an offset tape can be met in an optimal manner without plating. Due to the significantly less steered rolling structure of the surface layer, mechanical and electrochemical roughening of the printing plate is possible, which has a homogeneous and fine-grained structure on the surface to be coated. The streaked rolled structure in the core ensures the necessary strength even after a possible thermal aftertreatment.
- the hot rolling process is controlled according to the invention in such a way that recrystallization cannot take place over the entire cross section of the offset strip, but only in the edge zones. This results in a non-recrystallized core zone with a streaked roll structure, which is important for the increased mechanical properties. Numerous tests have shown that a surface area of 10 to 30% - preferably 15% - with a globular structure is sufficient for the electrochemical roughening.
- the globular grain structure of the hot strip is lengthened by the subsequent cold rolling, but has a significantly lower stretching of the edge zone compared to the core.
- the grains elongated in the rolling direction have an elongation of s less than 8 on the surface, the core zone elongation values of s greater than 16.
- the evaluation method of R. Dederichs and H. Kostron was used.
- the comparative experiment shows that the method according to the invention leads to an offset band which has the surface suitable for electrochemical roughening with very favorable mechanical properties.
- the mechanical properties can be improved to such an extent that the decrease in strength that would otherwise be expected after a thermal treatment of more than 200 ° C. is only delayed and occurs to a much lesser extent.
- the yield point ratio is a measure of the stiffness of the belt. The stiffness must be sufficiently high for good handling, in particular of thin strips.
- the offset tape produced according to the invention is therefore superior to the material hitherto used for these purposes, which does not have sufficient rigidity after the stoving temperature frequently used for offset purposes.
