Definitions
- This invention relates to a method for the production of a metallic support for use as a substrate for a lithographic printing plate. More specifically, the invention provides a method for the surface treatment of a metallic sheet, most particularly an aluminium sheet, whereby a substrate having particularly favourable lithographic properties may be obtained.
- aluminium substrates intended for use as support materials for lithographic printing plates and their precursors have generally been subjected to surface treatments prior to application of a light sensitive coating material. These treatments serve to improve the lithographic properties of the aluminium, in particular, its hydrophilicity. This is important during printing operations, since the basis of lithography is the ability of the lithographic plate to accept ink in image areas whilst rejecting ink and accepting water in background (non-image) areas, so that the printed image remains free from dirt and other contamination in said background areas.
- the light-sensitive coating of a lithographic printing plate precursor is imagewise exposed to radiation in order to change the solubility characteristics of the coating in the radiation-struck areas. The soluble areas are subsequently dissolved away by treatment with a developing solution, to expose the aluminium surface which must be capable of rejecting ink and accepting water.
- a typical surface treatment comprises an initial graining treatment, wherein the aluminium surface is roughened by either mechanical or electrochemical means, and a subsequent anodising treatment, by means of which a layer of aluminium oxide is formed on the surface of the aluminium.
- Anodising treatments may, for example, be carried out by passing a grained aluminium web through a bath of a suitable anodising acid, such as sulphuric or phosphoric acid, or a mixture thereof, whilst an electric current flows through the anodising bath and the web serves as the anode.
- post-anodic dip - is generally applied in order to improve specific lithographic printing properties of the substrate, such as clean up of background areas, coating adhesion or corrosion resistance, and will typically involve passing the aluminium through a solution, often an aqueous solution, of the chosen reagent.
- aqueous solutions containing, for example, sodium carbonate or bicarbonate, poly(acrylic acid) or various aqueous-soluble copolymers.
- the present invention seeks to provide a means whereby the costly and time-consuming substrate treatment steps involved in the preparation of suitable aluminium support materials for use in the preparation of lithographic printing plate precursors may be reduced in number and simplified, thereby facilitating substantial cost savings.
- a process for the manufacture of a support for a lithographic printing plate precursor comprising at least the steps of:
- Said metallic substrate may comprise any conducting metallic substrate but, most preferably, it comprises aluminium or an aluminium alloy containing small amounts of, for example, manganese, nickel, cobalt, zinc, iron, silicon or zirconium.
- Said substrate is generally provided in the form of a continuous web or roll of metal or metal alloy.
- said substrate is subjected to a degreasing treatment prior to said treatment with an aqueous solution of a salt of a metal.
- Said degreasing treatment is most conveniently carried out by means of an aqueous alkaline solution.
- said treatment involves passing said substrate through a bath containing a 5-20% w/v solution of, for example, sodium or potassium hydroxide.
- said substrate is rinsed with water prior to further treatment.
- Said treatment of said surface or surfaces with an aqueous solution comprising a salt of a metal from Group IB, IIB, IVA, IVB, VB, VIA, VIB, VIIB or VIII of the Periodic Table is preferably carried out by immersing said substrate in an aqueous solution, preferably containing from 0.001% to 5.0% (w/w) (more preferably from 0.01% to 1.0%) of said salt at a preferred temperature of from 5° to 80°C (more preferably from 15° to 40°C) for a preferred dwell time of from 1 second to 60 minutes (more preferably from 15 seconds to 5 minutes) at a pH of between 0 and 13 (preferably from 1 to 5, and most preferably in the region of 3).
- Said aqueous solution also preferably contains aluminium ions in an amount of from 0.1 to 50,000 ppm; said aluminium ions may be added to said aqueous solution in the form of any convenient aluminium salt or, in the case of an aluminium substrate, may be present as a result of dissolution from said substrate.
- Suitable salts which may be used for the said treatment include, for example, salts of titanium, zirconium, hafnium, molybdenum, tungsten, vanadium, manganese, nickel, copper, zinc, tin, niobium, tantalum, cerium, selenium, silicon, cobalt or iron.
- Said salts my include the metal either as the cation, for example in halide, sulphate or nitrate salts, or as part of a complexed anion.
- the hafnium, zirconium or titanium salt comprises a salt wherein the metal is present in a metal-complex anion, such as a chlorotitanate or fluorozirconate anion.
- a metal-complex anion such as a chlorotitanate or fluorozirconate anion.
- alkali metal fluorozirconates particularly potassium hexafluorozirconate.
- aqueous solution containing a metal salt may be incorporated in said aqueous solution containing a metal salt.
- polymers or copolymers of organic acids may be employed for this purpose, with particularly favourable results being achieved with poly(acrylic acid) or the copolymer of acrylic acid with vinyl phosphonic acid.
- Said materials my be added in an amount of from 0.001% to 5.0% (w/w) (preferably from 0.01% to 1.0%) to the treatment bath.
- the application of the constant voltage or constant current is preferably realised by applying a constant d.c., pulsed d.c., a.c. (sine and square waveforms), biased a.c. or half wave 1-6 phases rectified a.c. voltage of from 0.1 to 1000 V (preferably from 1 V to 100 V) across the treatment bath, using the substrate as one electrode and another electrical conductor, such as platinum, aluminium, carbon, stainless steel or mild steel as the other electrode.
- the aluminium substrate may form the cathode and the other electrical conductor may provide the anode; preferably, however, the aluminium substrate forms the anode, with the other electrical conductor providing the cathode.
- a surface film develops on said substrate, said film having a thickness of from 0.001 to 100 ⁇ m.
- said surface film may be produced with a textured surface finish.
- said substrate may be subjected to a graining treatment prior to said treatment with an aqueous solution of a salt of a metal.
- Said graining treatment may involve mechanical graining, wherein the surface of the substrate is subjected to mechanical forces which may, for example, be achieved by the use of a slurry of very small metal balls or via brush graining techniques.
- electrochemical graining may be employed; said technique comprises passing a substrate through a solution of a mineral or organic acid, or a mixture thereof, such as a mixture of hydrochloric and acetic acids, whilst applying an electric current to the acid solution.
- Typical graining conditions would involve the use of a bath of aqueous hydrochloric acid at a concentration of from 1-10 g/l and a temperature of 5-50°C, with a dwell time of from 1-60 seconds and an applied potential of from 1-40 V. The grained substrate is then rinsed with water prior to further processing.
- said grained substrate Following electrochemical graining, said grained substrate would be subjected to a desmutting treatment in order to remove by-products formed during the course of said electrograining treatment, and deposited on the surface of the substrate.
- a desmutting treatment in order to remove by-products formed during the course of said electrograining treatment, and deposited on the surface of the substrate.
- the process involves treatment of the grained substrate with an aqueous acid or alkali according to the methods well known in the art.
- the substrate is rinsed with water following desmutting.
- the support provided by the method of the present invention may subsequently be coated with a light-sensitive coating to give a lithographic printing plate precursor.
- coatings of the types well known to those skilled in the art may be applied for this purpose, for example, positive-working coatings incorporating quinone diazide derivatives, negative-working coatings incorporating diazo or azide resins or photocrosslinkable resins or silver halide based coatings.
- the coatings may be applied by any of the standard coating techniques known to the skilled person, such as curtain coating, dip coating, meniscus coating, reverse roll coating, and the like.
- the thus-obtained lithographic printing plate precursor may then be imagewise exposed and the non-image areas can be developed away to provide a lithographic printing plate which is subsequently used on a printing press to produce copies.
- Lithographic printing plates produced from aluminium supports obtained by the method of the present invention show good abrasion resistance, corrosion resistance, staining resistance and scumming resistance, both on plate development and on press.
- the surface film produced by the treatment according to the method of the present invention shows excellent coating adhesion in the image areas. Additionally, the plate exhibits very good exposure latitude and solvent resistance.
- a salt of this type may be incorporated in an anodising bath typically containing mineral acids such as sulphuric, phosphoric, nitric, hydrofluoric or chromic acids, or organic acids such as oxalic, tartaric, citric, acetic or oleic acids, or mixtures of these acids, thereby providing a support material which shows the advantageous properties previously discussed when incorporated in a lithographic printing plate.
