Definitions

  • the present invention relates to a process for producing a support for lithographic printing plates and, more particularly, to a process for producing a support for lithographic printing plates composed of a surface-grained aluminum plate and suitable for offset printing.
  • aluminum plates have been widely used as supports for lithographic printing plates.
  • the surface of the aluminum plate is usually grained for improving the adhesion to a light-sensitive layer formed thereon, and also for improving the water retention property of the non-image portions (the region receiving dampening water and repelling an oily ink as well as the exposed or uncovered region of the support) of a lithographic printing plate produced using the support.
  • the above-described graining treatment is an essential step in the preparation of the support for lithographic printing plates and requires a skilled technique.
  • Graining is generally classified as a mechanical graining method or an electric graining method.
  • Examples of the mechanical graining method are a ball graining method, a wire graining method and a brush graining method.
  • the water retention property is better.
  • the surface of the aluminum support it is preferable for the surface of the aluminum support to have as uniform a roughness as possible. As a method for obtaining such a preferred uniform surface roughness, attention has been directed to the electrochemical graining method.
  • an aluminum plate having a uniformly grained surface is obtained if various conditions such as the composition of the electrolyte, the temperature, the electrolytic condition, etc., are maintained constant. But the range of applicable electrolytic conditions is very narrow and, hence, it is very difficult to have all of the conditions satisfy the desired ranges for the electrolysis. Also, since the electrochemical graining requires a large amount of electric power, such graining is disadvantageous from an economical standpoint. Furthermore, in electrochemical graining, there is the disadvantage that a large amount of aluminum ions is accumulated in the electrolyte during electrolysis, and the labor and chemical cost for the treatment of the waste liquid is high.
  • methods for forming an uneven surface on the aluminum plate include a method of using a rolling roller having an inversion graining surface as disclosed in JP-A-55-74898 (the term "JP-A", as used herein, means an "unexamined published Japanese patent application”).
  • JP-A as used herein, means an "unexamined published Japanese patent application”
  • JP-A-60-36195 and JP-A-60-36196 disclose a method comprising forming elliptical concaved portions having an average long axis of from 10 to 140 ⁇ m and an average short axis of from 7 to 80 ⁇ m on a support and, thereafter, chemically or electrochemically forming a fine unevenness of from 1 to 10 ⁇ m.
  • JP-A-60-203496 discloses an aluminum plate prepared by transferring an unevenness having an average diameter of from 10 to 100 ⁇ m to the surface of the aluminum plate by means of a roller having the embossed surface and, thereafter, subjecting the aluminum plate to a chemical etching treatment and an electrochemical etching treatment.
  • An object of the present invention is, therefore, to solve the above-described problems, and to provide a process for producing a support for a lithographic printing plate having a sufficiently uniform unevenness without the need for adhering to the working precision such as the cylindrical property of the transfer roller, etc., and also without need for controlling changes in the thickness, the elongation, etc., of the aluminum plate.
  • the present inventors have found that in a process of bringing an uneven surface into contact with the surface of an aluminum plate under pressure to transfer the roughness onto the surface of the aluminum plate, a sufficiently uniform uneven surface for the aluminum support of lithographic printing plates can be obtained without the need for the precision of a transfer roller such as the cylindrical property, etc., and with reducing the elongation of the aluminum plate by carrying out the transfer a plurality of times.
  • the present inventors have completed the present invention based on the above finding.
  • the above-described object can be achieved by a process which comprises bringing an uneven surface into contact with the surface of an aluminum plate under pressure to form the unevenness on the surface of the aluminum plate by transfer, carrying out the transfer at least 3 times.

  • Fig. 2 is a surface photograph (375 magnifications) of the aluminum plate obtained in Comparative Example 9.

  • the surface of the roller may be further subjected to a known etching treatment to round the square-shaped unevenness thus formed.
  • quenching, hard chromium plating, etc. may be applied to the surface of the roller for increasing the hardness of the surface.
  • the surface of an aluminum plate thus grained by the transfer is preferably subjected to a chemical or electrochemical etching treatment in an aqueous solution of an acid, an alkali, or a neutral salt and then electrochemically grained in an aqueous solution of an acid or a neutral salt using an alternating electric current, a direct electric current, or a pulse direct electric current, whereby the aluminum plate becomes more suitable as a support for lithographic printing plates.
