A METHOD AND A PLATE FOR DIGITALLY-IMAGED OFFSET PRINTING

An offset plate sensitive to UV or visible light, prepared simply and imaged digitally therewith in a CTP method, and also processed in a simple manner. The plate is provided as a photopolymer plate with increased sensitivity, and is used in a simple imaging-on-press system, using the surface of a lithographic printing cylinder itself as a plate substrate. The method of preparing the printing plate begins by applying a photosensitive liquid coating to the substrate, digitally imaging the coated substrate, using an actinic light source to polymerize portions of the liquid coating in accordance with the imaging, and washing the liquid coating with an aqueous solution after the imaging to remove unpolymerized portions of the liquid coating. The typical constraints on coatings for offset lithographic plates are removed by utilizing sticky or wet layers as coatings so that little or no binder is present to interfere with the sensitivity or ease of processing.

Improvements in or relating to printing

A printing form precursor comprises a printing surface which comprises an inorganic metal compound, the printing surface being hydrophobic and capable of being made hydrophilic by energy but capable of becoming hydrophobic again, for reuse, if desired. An associated method of printing includes steps of subjecting the printing surface imagewise to energy so as to locally increase its hydrophilicity sufficient to make the surface differentiated in its acceptance of an oxophilic a printing ink; applying the ink to the printing surface and printing from the printing surface; causing or allowing the printing surface to undergo a reduction in hydrophilicity sufficient again to make the printing surface uniform in its acceptance of a printing ink; and,if wished, repeating these steps on multiple occasions. Thus the invention achieves the goal of providing a printing form precursor which does not need a chemical developer, and which can be used multiple times, to print different images.

ABSTRACT OF THE INVENTION A lithographic fountain solution concentrate is disclosed, the essential components of which comprises an aqueous mixture of: a) from about 0.1 to about 1.5 percent by weight of a water soluble film forming hydrophilic gum; b) from about 0.75 to about 8.5 percent by weight of Polyvinyl Pyrrolidone; c) from about 5.0 to about 30.0 percent by weight of a water soluble acid etchant; d) from about 20.0 to about 50.0 percent by weight of a water soluble or water miscible glycol; and e) from about 0.01 to about 1.25 percent by weight of a phosphate/phosphoric acid buffer system. The concentrate is adapted for further dilution by water to yield a fountain solution which when used in the printing process offers decreased scumming and blinding of printing plates while at the same time permitting a reduction in the amount of water applied to the plate. Improved print quality, reduced tendency to wet the paper, faster ink drying and improved ink/water balance is thereby achieved.

Plates for offset reprodn - correction using a universal solvent mixt

Proofreading compsn. comprises (a) DMSO for cleaning the sensitive resin layer, (b) at least one cyclic ether as resin solvent, (c) at least one alkyl acetate, ketone and/or chlorinated aliphatic or aromatic hydrocarbon, as ink solvent, (d) hydrofluoric acid as mordant and (e) finely divided silica as thicknener, the compsn. being in the form or a water-soluble colloidal gel. The compsn. may be used on all types of plate currently in use. It is easily and rapidly used on presensitised aluminium plates.

Aq. hydrophilising bath for treating offset printing plates - contains polynuclear metal complex, phosphate and acid

Offset prints are produced by using an aq. hydrophilising bath contg. (a) 5-60 g/l of >=1 multi-nuclear metal complex contg. Zn, Ir, Co, Ti, Fe, Cu, Ni, Pt, Mn, Ru, Rh, He, V or Be as nucleating metal, bonded to >=1 ligand, consisting of O, O2, F, CL, Br, NH, NH2, NO2, SO4 or AcO, (b) 5-100 g/l phosphate, and (c) an inorganic acid. The baths can be applied to electrophotographic and direct image printing plates. The baths have high hydrophilising capacity; quickly form a strong, hydrophilic film; resist light and heat and cause no health hazards. The complexes form hydrophilising salts which are solid, stable and difficultly soluble in water in the presence of metal ions. The combination of phosphate and metal complex improved water retention and printing ink repulsion.
