Definitions

  • the invention relates to a process for producing aluminum strips for lithographic printing plate supports, wherein the aluminum strip is produced from a rolling bar, which after optional homogenization hot rolled to a thickness of 2 mm to 7 mm and to a final thickness of 0.15 mm to 0.5 mm cold rolled.
  • the invention relates to a correspondingly produced aluminum strip having a thickness of 0.15 mm to 0.5 mm and a pressure plate carrier made of the aluminum strip according to the invention.
  • the aluminum strip for the production of lithographic printing plate supports is usually subjected to an electrochemical roughening, which should result in a blanket roughening and a structureless appearance without streaking effects.
  • the roughened structure is important for applying a photosensitive layer, which is subsequently exposed.
  • the photo-layer is baked at temperatures of 220 ° C to 300 ° C and annealing times of 3 to 10 minutes, typical combinations of burn-in times being for example 240 ° C at 10 minutes, 260 ° C at 6 minutes and 260 ° C for 4 minutes.
  • the pressure plate carrier must after burning as possible lose little strength, so that it is still easy to handle and can be easily clamped in a printing device.
  • the printing plate support and thus also the correspondingly produced aluminum strip must have the highest possible flexural fatigue strength, so that plate outlier can be virtually eliminated due to mechanical stresses on the printing plate. So far, these requirements have been well met with conventional aluminum strips.
  • the handling of large lithographic printing plate supports becomes more difficult with increasing size and consistent strength values.
  • the present invention has the object to provide a method for producing an aluminum strip for lithographic printing plate support and a corresponding aluminum strip available, the coil set is easily correctable in hard-rolling condition and from which also oversized printing plate support can be produced, which is easy to handle and only show a low tendency to plate tears.
  • Residual Al and unavoidable impurities individually max. 0.05%, in total max. 0.15%, during the cold rolling an intermediate annealing is carried out at a thickness of 1.5 mm to 0.5 mm, the aluminum strip is then rolled by cold rolling to a final thickness of 0.15 mm to 0.5 mm and for further processing to one lithographic printing plate support is rolled up in hard-rolled condition.
  • the aluminum strip produced according to the invention can provide a moderate increase in strength together with a very high flexural fatigue resistance and at the same time very good thermal stability. Coilset corrections are possible without difficulty due to the moderate increase in strength. At the same time, however, the handling of the printing plate even in a baked state, for example when clamping in the printing press, is simple, since a good thermal stability of the aluminum strip is obtained by the method according to the invention. If the aluminum strip is used for the production of very large lithographic printing plate supports, preferably the aluminum strip is cold rolled to a final thickness of 0.25 to 0.5 mm after the intermediate annealing.

Titanium is commonly used for grain refining during casting. However, an increased Ti content leads to casting problems. Zinc affects the Aufrauley, so that its content max. Should be 0.05 wt .-%.

  • the metal temperature of the aluminum strip is 200 ° C to 450 ° C.
  • the aluminum band will then be for at least one to two Hours kept at the metal temperature. This is usually done in batch ovens. Due to the intermediate annealing in the temperature range mentioned, the further processing of the aluminum strip can take place either in a recovered or recrystallized state or a combination of both.
  • the recrystallization starts at temperatures of about 300 to 350 ° C, which depends on the manufacturing parameters, in particular the introduced solidifications.
  • a regeneration annealing at lower temperatures merely results in a reduction of the solidifications, so that very low degrees of reduction after recovery annealing are possible.
  • the aluminum strip has a tensile strength of up to 200 MPa in hard-rolled condition along the rolling direction and after baking at a temperature of 240 ° C and a duration of 10 minutes of at least 145 MPa, as well as a bending resistance transverse to the rolling direction of at least 1850 cycles in the bending cycle test.
  • the aluminum strips according to the invention achieve bending cycle cycles of more than 1850, also transverse to the rolling direction, which means an increase of more than 70% compared with the standard alloys used hitherto. Due to the moderate increase in tensile strength measured to values up to 200 MPa in hard-rolling condition along the rolling direction, the coil set of the aluminum strip according to the invention can be further corrected in a simple manner.
  • the handling of the lithographic printing plate carrier produced from the aluminum strip is also good after a baking process. Even with very large lithographic printing plate supports can be facilitated by the increased strength after baking, the handling of the printing plates.
  • the high number of possible bending cycle cycles greater than 1850 both in the hard as well as in the baked state of the aluminum strip according to the invention that the tendency to As a result of mechanical stresses, plate cracks are small in the case of lithographic printing plate supports clamped transversely or longitudinally to the rolling direction.
  • the properties of the finished aluminum strip are thereby achieved process reliable, that the aluminum alloy has a Ti content of max. 0.05% by weight, preferably max. 0.015 wt .-%, a Zn content of max. 0.05 wt .-% and a Cr content of less than 100 ppm, preferably of max. 10 ppm.

  • the ingots cast from the various aluminum alloys have been subjected to homogenization prior to rolling, the ingots being annealed to a temperature of about 580 ° C for more than four hours. Subsequently, the hot rolling was carried out at temperatures of 250 ° C to 550 ° C, the hot strip temperature was between 280 ° C and 350 ° C.

  • the correspondingly produced aluminum strips for lithographic printing plate supports or litho tapes were subjected to further tests. All four aluminum bands are characterized by a very good roughening behavior.
  • the tensile strength in the hard-rolled state was investigated. In order to test the practical handling of the printing plates, especially for oversized lithographic printing plates, tensile strengths were measured even after a baking process of 240 ° C for 10 minutes.
