Definitions

  • the present invention relates to a method for producing a planographic printing plate aluminum support by using a twin-roll continuous casting method. Particularly, the present invention relates to a method for producing a planographic printing plate aluminum support which is good in surface quality so that stripe-like surface-quality defects can be prevented from being generated in an aluminum plate continuously or intermittently in its rolling direction.
  • An aluminum plate (including an aluminum alloy plate) is used as a printing plate aluminum support, especially, as an offset printing plate support.
  • the aluminum plate is required to have both moderate attaching property and moderate water retention property with respect to a light-sensitive material.
  • the surface of the aluminum plate must be roughened to have uniform and fine particles. Because the surface-roughening treatment has a remarkable influence on both the printing performance and printing endurance of the plate material when offset printing is actually performed after plate making, the quality of the surface-roughening treatment becomes an important factor for production of the plate material.
  • An AC electrolytic etching method is generally used as a method for roughening the surface of the printing plate aluminum support.
  • an electric current an ordinary sinusoidal alternating current or a special alternating-waveform current such as a rectangular-wave current or the like is used.
  • a suitable electrode made from graphite or the like was used as a counter electrode so that the surface of the aluminum plate was roughened by an alternating current.
  • the treatment was generally performed by one step and the pit depth obtained therein was shallow as a whole, so that printing endurance was poor. Therefore, various methods have been proposed to obtain an aluminum plate adapted for a printing plate support having a grained surface in which pits each having a depth larger than its diameter exist uniformly and finely.
  • JP-A-53-67507 a surface-roughening method using a special electrolytic electric source waveform
  • JP-A means Unexamined Japanese Patent Publication (kokai)
  • JP-A-54-65607 the ratio of an anodic electric quantity to a cathodic one at the time of electrolytic surface-roughening by means of an alternating current
  • JP-A-55-25381 electric source waveform
  • JP-A-56-29699 combination of the quantity of current conduction per unit area
  • an ingot of aluminum is melted and held so that a slab (thickness: 400 to 600 mm; width: 1000 to 2000 mm; and length: 2000 to 6000 mm) is cast.
  • An impurity structure portion in a surface of the slab is subjected to a face mill cutter so as to be cut by a depth in a range of from 3 to 10 mm.
  • a heat holding step for holding a temperature in a range of from 480 to 540°C for a time in a range of from 6 to 12 hours is performed in a heat holding furnace in order to remove stress in the inside of the slab and make the structure uniform.
  • hot rolling is performed at a temperature in a range of from 480 to 540°C.
  • cold rolling is performed at room temperature to obtain a predetermined thickness.
  • annealing for making the structure uniform is performed so that the rolled structure, or the like, is homogenized, cold rolling is performed to a defined thickness to correct the plate to have good flatness.
  • the thus produced aluminum support is used as a planographic printing plate support.
  • the electrolytic surface-roughening is, however, particularly easily affected by the aluminum support which is a subject. Therefore, when the aluminum support is produced by the steps of melting holding, casting, face mill cutting and heat holding, metal alloy components etc. in the surface layer of the aluminum support may scatter to bring a cause of lowering of yield of the planographic printing plate even in the case where not only heating and cooling are repeated but also a face mill cutting step for cutting the surface layer is provided.
  • the following method for producing a planographic printing plate support has been proposed as a method in which not only variation in the material of the aluminum support is reduced but also the yield of the electrolytic surface-roughening treatment is improved to thereby produce an excellent-quality good-yield planographic printing plate (U.S. Patent No. 5,078,805 corresponding to JP-A-3-79798).
  • the method comprises the steps of continuously performing casting and hot rolling to form a thin-plate hot-rolled coil from molten aluminum, and performing cold rolling, heating and correction to roughen a surface of the aluminum support.
  • JP-B-52-23327 (hereinafter, JP-B means Examined Japanese Patent Publication), JP-A-2-290652, JP-A-1-215441, JP-A-62-248543, JP-A-61-1456, British Patent No. 2198976, U.S. Patent No. 4716956, Canadian Patent No. 619491, etc. are known as known patents.
  • stripe-like surface-quality defects may be generated continuously or intermittently in the aluminum plate in its rolling direction. That is, the flow of molten metal in the molten metal supply nozzle changes in accordance with the difference in the particle size distribution of a release agent applied onto the inner surface of the molten metal supply nozzle, so that the molten metal does not flow uniformly and stably. Accordingly, the flow-disturbed portions form stripe-like surface-quality defects. There arose a problem that the yield of production was lowered.

  • molten aluminum is supplied from the molten metal supply nozzle to finally form an aluminum thin plate having a thickness in a range of from 0.1 mm to 0.5 mm
  • the flow of molten metal in the molten metal supply nozzle is uniform and stable owing to the function of the release agent containing aggregate particles to prevent stripe-like surface-quality defects.

  • boron nitride (BN), graphite, table, molybdenum disulfate, fluororesin, zirconium silicate or the like is used as the release agent, and water, organic solvent or the like is used as the aggregate contained in the release agent.
  • a thin-plate continuous casting technique such as a Hunter method, a 3C method, or the like, has been put into practical use as the method for casting a plate-like matter directly from molten aluminum by using a twin roll to form a thin-plate coil.
  • Fig. 1 is a schematic view showing the steps of the method for producing an aluminum support according to the present invention.
  • a melting hold furnace 1 is tilted to thereby feed molten aluminum to a gutter 2.
  • the liquid level of the gutter 2 is detected by a liquid level sensor 7 and a melting furnace tilting motor 9 is controlled through an amplifier 8 to thereby control the supply quantity of the molten metal to keep the liquid level of the gutter 2 constant.
  • a crystal particle refining wire 10 is supplied to the molten metal as occasion demands. In order to suppress the generation of oxide of the molten aluminum and remove an alkali metal harmful to quality, inert gas purging, fluxing, or the like, is performed suitably.
  • the molten metal is supplied to a gap between a pair of cooling rollers 4a and 4b from a molten metal supply nozzle 3 having an inner surface which is brought into contact with the molten metal and which is coated with a release agent containing aggregate particles having a particle size distribution with a median size in a range of from 5 ⁇ m to 20 ⁇ m and a mode size in a range of from 4 ⁇ m to 12 ⁇ m.
  • the molten metal is rolled to thereby produce a cast plate.
  • the cast plate ejected from the cooling rolls 4a and 4b can be wound up by a coiler 6 or can be sampled suitably by a cutter 5.
  • the thus obtained plate material is rolled into a defined thickness by a cold rolling apparatus 11 shown in Fig. 2.
  • a heating step such as intermediate annealing, etc. may be performed and then the cold rolling apparatus 11 may be provided in order to make the crystal particle size uniform.
  • the plate material is corrected by a corrector to thereby give predetermined surface flatness, produce an aluminum support and roughen the surface of the aluminum support.
  • correction may be included in the final cold rolling.
  • the method for roughening the surface of a planographic printing plate support according to the present invention is used variously for mechanical surface roughening, chemical surface roughening, electrochemical surface roughening, combination thereof, etc.
  • Examples of a mechanical graining method include a ball grain method, a wire grain method, a brush graining method, a liquid honing method, etc.
  • an electrochemical graining method an AC electrolytic etching method is generally used, in which, as an electric current, an ordinary sinusoidal alternating current or a special alternating current such as a rectangular-wave current, or the like, is used.

  • the preferred etching quantity is in a range of from 0.01 to 1 g/m 2 (JP-A-1-237197). Succeedingly, desmutting may be performed as occasion demands, because alkali-insoluble components (smut) remains on the surface of the alkali-etched aluminum plate.
  • a stripe-like surface-quality defect appears as a result of the aforementioned etching with sodium hydroxide, or the like, when the stripe-like surface-quality defect is generated continuously or intermittently in the aluminum plate in its rolling direction.
  • AC electrolytic etching is performed in an electrolytic solution mainly containing hydrochloric acid or nitric acid.

If the sulfuric acid concentration is not lower than 400 g/l or if the temperature is not lower than 65°C, not only corrosion of a treating tank, or the like, increases but also electrochemically surface-roughened particles are collapsed in an aluminum alloy containing 0.3 % or more of manganese. Further, if etching is performed so that the quantity of the dissolved aluminum ground is not smaller than 0.2 g/m 2 , printing endurance is lowered. Accordingly, the quantity of the dissolved aluminum ground is preferably not larger than 0.2 g/m 2 .
