Definitions

  • the present invention relates to an aluminium alloy, which is useful for printing plate making, especially for (computer) direct-to-plate.
  • the invention also relates to an article produced from the alloy, which article is, e.g., in the form of sheet, strip or foil, and to a process of producing same.
  • Document JP2008063667 discloses an aluminium alloy material for lithography.
  • Document CN101182611A discloses an alloy composition for lithographic sheets.
  • PS plate presensitized plate
  • CTP plate computer-to-plate
  • the printing requires stringently on the plate, where the CTP technology requires particularly stringently on the CTP plate and the properties of the aluminium alloy sheet, strip or foil to produce the CTP plate, such as the appearance properties, physical properties and adaptability to electrolysis.
  • the current CTP plates are generally used for high grade of color printing plate-making.
  • the properties of the plate substrate are the foundation.
  • the printing field generally requires the follows:
  • the appearance of the aluminium alloy sheet/strip/foil is required to be clean and smooth; have no defects of crack, corrosion hole, corrosion spot, through hole, scratch, fold, impression, peeling, pine pattern mark or oil mark; have no press-in mark by a non-metal, sticking mark, peeling or wave on the surface; have no chromatic aberration or highlighting band; and have no swelling or wavy edges.
  • the grain of the substrate of the CTP plate is lower than that of the PS plate.
  • the CTP plate-making device generally uses a FM screening or FM/AM mixed screening, such that the reduction of fine screen dot and screen line is associated directly with the surface roughness of the substrate, i.e., the grain of the substrate. The greater the grain is, the worse the reduction of the screen dot and screen line is.
  • the appearance quality and the surface roughness of the substrate should be focused. If the appearance quality of the substrate is too bad, the defects of the plate surface cannot be eliminated without a strengthened electrolysis, resulting in a greater grain. If the substrate has a Ra ⁇ 0.30 ⁇ m, it is difficult to obtain a lower grain.
  • the inherent composition of the aluminium substrate is the core. That is, the components of the aluminium alloy to produce the aluminium plate are interested, which, in turn, are associated with the composition and contents of the specific metals of the aluminium alloy.
  • the process of preparing or treating the aluminium alloy is also concerned.
  • a good aluminium alloy sheet/strip/foil requires not only good mechanical properties but also good adaptability to electrolysis, so as to be useful for electrolysis with hydrochloric acid or nitric acid electrolyte.
  • a sensitivity of grain corresponding to the electrolysis is also required, so as to form a layer with fine and uniform grain without a strengthened treatment.
  • the aluminium alloy sheet/strip/foil for the CTP requires a high planeness, as most of the CTP apparatuses use scanning imaging, different from the printing-down for the PS plate where a vacuum is applied to tight the plate with the film. Then, if the plate has a poor planeness, the quality of the imaging by laser will be affected adversely. Therefore, the aluminium alloy sheet/strip/foil for CTP requires stringently on the planeness.
  • the AA1050 alloy is popularly used.
  • those skilled persons can refer to " Quality Requirements and Typical Defects Analysis of Aluminium Material for CTP", Aluminium Fabrication, 2008.3, Vol. 182 , such as the aluminium substrate introduced.
  • the quality of electrochemical roughening is affected by a plurality of factors, such as the electric current density, the linear velocity, the chemical components and the like.
  • an AA1050 alloy is generally used, where the content of aluminium is controlled to be 99.5% or more.
  • the controlling standard can refer to the International Designations Chemical Composition Limits for Unalloyed Aluminium, 2003, edited by The Aluminium Association, USA, see www.aluminium.org .
  • the CTP substrate prepared according to the Table above comprises the typical mechanical properties of: a tensile strength of 130-150MPa, a yield strength of 120-140MPa, and an elongation of 1.0-3.0%, at room temperature; and a tensile strength of 120-130MPa, a yield strength of 110-120MPa, and an elongation of 2.0-3.5%, at a baking temperature. It can be seen that the properties are not so stable, decreasing the printing quality.
  • the grain of the substrate of the CTP plate is lower than that of the PS plate.
  • the CTP plate-making device generally uses a FM screening or FM/AM mixed screening, such that the reduction of fine screen dot and screen line is associated directly with the surface roughness of the substrate, i.e., the grain of the substrate. The greater the grain is, the worse the reduction of the screen dot and screen line is.
  • the AA1050 alloy has poor uniformity for the internal structure, such that the electrolysis properties are undesirable, and the grains after electrolytic roughening are not uniform, resulting too poor reduction to satisfy the requirement by the high grade of CTP plate.
  • the aluminium sheet/strip/foil has a uniform internal structure, such that besides the high surface quality and good planeness of the plate, the sheet/strip/foil has improved mechanical properties at room temperature and improved mechanical properties at a baking temperature, and also can generate an excellent grain structure through electrolysis.
