Definitions

  • the present invention relates to a heat-sensitive material for preparing lithographic printing plates.
  • the invention is related to a processless heat-sensitive material which yields lithographic printing plates with no scumming and a good ink acceptance.
  • Rotary printing presses use a so-called master such as a printing plate which is mounted on a cylinder of the printing press.
  • the master carries an image which is defined by the ink accepting areas of the printing surface and a print is obtained by applying ink to said surface and then transferring the ink from the master onto a substrate, which is typically a paper substrate.
  • ink as well as an aqueous fountain solution are fed to the printing surface of the master, which is referred to herein as lithographic surface and consists of oleophilic (or hydrophobic, i.e. ink accepting, water repelling) areas as well as hydrophilic (or oleophobic, i.e. water accepting, ink repelling) areas.
  • Printing masters are generally obtained by the so-called computer-to-film method wherein various pre-press steps such as typeface selection, scanning, colour separation, screening, trapping, layout and imposition are accomplished digitally and each colour selection is transferred to graphic arts film using an image-setter.
  • the film can be used as a mask for the exposure of an imaging material called plate precursor and after plate processing, a printing plate is obtained which can be used as a master.
  • EP-A- 786 337 discloses a process for imaging a printing plate, wherein the printing plate is charged over the whole surface and over the whole surface is covered with toner particles, which are charged oppositely. Thereon is the layer, formed by the particles imagewise fixed or imagewise ablated by infrared exposure on the surface of the printing plate. Thereafter the parts which are not fixed are removed and optionally the non-ablated areas are fixed by heating over the whole surface of the plate. This process requires a cumbersome development.
  • thermal materials disclosed in the prior art are suitable for exposure with either an internal drum image-setter (i.e. typically a high-power short-time exposure) or an external drum image-setter (i.e. relatively low-power long-time exposure).
  • an internal drum image-setter i.e. typically a high-power short-time exposure
  • an external drum image-setter i.e. relatively low-power long-time exposure
  • thermoplastic polymer beads for making a negative working non-ablative lithographic printing plate

  • thermoplastic polymer beads have a diameter between 0.2 ⁇ m and 1.4 ⁇ m, preferably a diameter between 0.5 and 1.2 ⁇ m.
  • the printing plate shows scumming, while when the thermoplastic polymer beads are bigger than said diameters , the printing plate does not ink up sufficiently.
  • Thermoplastic particles with a to small diameter adheres to well to the metallic support and are not completely removed by the ink and/or fountain solution.
  • Thermoplastic polymer beads with a to big diameter even after coagulation by the infrared irradiation, does not adhere well enough to the metallic support on the imaged areas. Only thermoplastic polymer beads with a diameter in the claimed range strikes the right balance between adsorption in the imaged areas and removal by ink and/or fountain solution in the non-imaged areas.
  • thermoplastic polymer particles used in connection with the present invention preferably have a coagulation temperature above 50°C and more preferably above 70°C. Coagulation may result from softening or melting of the thermoplastic polymer particles under the influence of heat.
  • the coagulation temperature of the thermoplastic hydrophobic polymer particles there is no specific upper limit to the coagulation temperature of the thermoplastic hydrophobic polymer particles, however the temperature should be sufficiently below the decomposition temperature of the polymer particles.
  • the coagulation temperature is at least 10°C below the temperature at which the decomposition of the polymer particles occurs.
  • hydrophobic polymer particles for use in connection with the present invention have a Tg above 80°C.

  • the roughening of the aluminum foil can be performed according to the methods well known in the prior art.
  • the surface of the aluminum substrate can be roughened either by mechanical, chemical or electrochemical graining or by a combination of these to obtain a satisfactory adhesiveness of a silver halide emulsion layer to the aluminum support and to provide a good water retention property to the areas that will form the non-printing areas on the plate surface.
  • the electrochemical graining process is preferred because it can form a uniform surface roughness having a large average surface area with a very fine and even grain which is commonly desired when used for lithographic printing plates.
  • the roughening is preferably preceded by a degreasing treatment mainly for removing greasy substances from the surface of the aluminum foil.
  • the aluminum foil may be subjected to a degreasing treatment with a surfactant and/or an aqueous alkaline solution.
  • Preferably roughening is followed by a chemical etching step using an aqueous solution containing an acid.

  • the aluminum oxide surface may be rinsed with a citric acid or citrate solution. This treatment may be carried out at room temperature or may be carried out at a slightly elevated temperature of about 30 to 50°C.
  • a further interesting treatment involves rinsing the aluminum oxide surface with a bicarbonate solution.
  • the aluminum oxide surface may be treated with polyvinylphosphonic acid, polyvinylmethylphosphonic acid, phosphoric acid esters of polyvinyl alcohol, polyvinylsulphonic acid, polyvinylbenzenesulphonic acid, sulphuric acid esters of polyvinyl alcohol, and acetals of polyvinyl alcohols formed by reaction with a sulphonated aliphatic aldehyde It is further evident that one or more of these post treatments may be carried out alone or in combination.
  • image is used herein in the context of lithographic printing, i.e. "a pattern consisting of oleophilic and hydrophilic areas".
  • the material that is made according to the present invention is negative working, which means that the areas, which are exposed to light, are rendered oleophilic and thus ink accepting due to said exposure.
  • the feature "negative working” may be considered as an equivalent of the feature “non-ablative", since in ablative materials the functional layers are completely removed from the underlying (hydrophilic) metal support upon image-wise exposure so as to obtain a positive image (exposed areas are hydrophilic, ink repelling).
  • Analysis of the exposed areas of the material made according to the method of the present invention indeed showed that the layer or stack of layers is not removed upon image-wise exposure but is converted into a hydrophobic surface on the metal support.
  • the unexposed areas are hydrophilic.

  • the imaging element is image-wise exposed. During said exposure, the exposed areas are converted to hydrophobic and oleophilic areas.
  • Said image-forming can be realized by direct thermal recording wherein the thermal transfer is effected by heat radiation, heat conductivity or inductive heat transport. On the heated areas the hydrophobic polymer particles coagulate and forms a hydrophobic area.
  • Said image-forming can also effected by irradiation with high intensity light.
  • the heat-sensitive material should then comprise a compound capable of converting light into heat.
  • Image-wise exposure in connection with the present invention is preferably an image-wise scanning exposure involving the use of a laser or L.E.D.
  • a laser or L.E.D Preferably used are lasers that operate in the infrared or near-infrared, i.e. wavelength range of 700-1500 nm. Most preferred are laser diodes emitting in the near-infrared.
