Abstract
The invention belongs to the field of ink-jet printing, and particularly relates to an ink with high hiding rate for ink-jet printing and an application of the ink to the preparation of a flexible plate. The ink comprises the following components by weight percent: 5-30wt% of a polymer, 1-10wt% of an acrylate prepolymer, 0.01-5wt% of a dispersion stabilizer, 1-10wt% of a photoreactive monomer, 0.01-2wt% of a photoinitiator, 0.1-10wt% of an ultraviolet-light absorbing substance and the balance of a solvent. The ink is prepared by grinding and dispersing the components by a grinder until the diameters of nano metal particles are less than 300nm. The ink is jetted on the surface of the base of the flexible plate by an ink-jet printer to form a picture, and then the picture is printed on the base of the flexible plate in a conventional way, thus the procedures of film exposure, development and fixation are omitted, and the picture and the text on the flexible plate are clear and have good printability, excellent printing resistance and high printing efficiency when being printed by the ink-jet printer.
Description
Technical field
The invention belongs to the spray ink Printing field, be specifically related to spray ink Printing with high hiding rare, low-transmittance ink, more specifically relate to the application of this ink inside in gentle version preparation.
Background technology
Flexographic printing; this mode of printing is low with its printing cost, printable fabric is extensive, production efficiency is high, operate and maintenance is simple, be conducive to advantages such as environment protection and suitable print field wide ranges; be described as the printing process of " green printing " mode, " fitst water; the most promising ", obtained development rapidly in the whole world.
Types such as flexographic, photopolymer plate and digital photopolymer plate have been experienced in the development of flexible plate, wherein the flexographic method for platemaking is to form by engraving, mold pressing or the laser sculpture natural rubber through sulfidizing, wherein engrave needs pattern to change to open up, icking tool scribes process, because flexographic hardness is lower, picture and text copy and are very restricted, it is very high to printmaker's technology and experience requirement to add this method for platemaking, and low grade of production efficiency eliminated gradually.Mold pressing plate-making then needs to make earlier metal relief printing plate compacting matrix paper or metal matrix, by matrix masterplate compacting flexographic, flexographic is heated, pressurizes, adds sulphur again, and hardening is made forme after handling.Because this long in mode plate-making cycle, the plate-making thickness evenness is relatively poor, be unfavorable for that environment protection etc. does not re-use.The laser sculpture flexographic is newest fruits in recent years, but because the limitation of rubber itself and the extensive employing of photopolymer plate, this kind technology also is of little use.
Photopolymer plate is divided into solid photopolymer plate and liquid photopolymer plate.The solid photopolymer plate material therefor is selected from derivatived cellulose, polyvinyl alcohol derivative, butadiene styrene resin etc., and the fragility of version is bigger, and cost is higher.The liquid photopolymer plate is that support is made plate with the polyester film, mostly is unsaturated polyester series, and cost is low than solid photopolymer plate, and printing quality is also better.
The composition of photopolymer plate is seen accompanying drawing 1.
Must see accompanying drawing 2 through following treatment step during photopolymer plate plate-making.
By the plate-making process complex treatment process of the visible photopolymer plate of above-mentioned treatment step, higher to operator's technical requirements.
Computer directly flexographic plate processed is by the black film formation negative on laser ablation flexibility plate surface, carries out procedure of processings such as the exposure identical with photosensitive flexographic plate plate-making mode, development (flushing), drying, aftertreatment, post-exposure then.Compare with photopolymer plate commonly used, increased laser absorption layer (black film), changed exposure light source (laser imaging), and technology and photopolymer plate commonly used are loaded down with trivial details equally.
The present invention is intended to by ink-jet printer the ink of high hiding rare, low-transmittance to be sprayed on a gentle version version primary surface and forms an image, exposure under the UV-light that the gentle version version base that will be coated with described ink then is 300～450nm at wavelength, development, thereby omitted the treatment step that utilizes exposure, development, photographic fixing, the picture and text of the gentle version of gained are clear, have good printability and higher pressrun when last machine prints.High hiding rare of the present invention, low-transmittance ink utilize the mode of spray ink Printing, have omitted exposure, development, the fixing of film, have improved the efficient of gentle version plate-making.
Summary of the invention
Main purpose of the present invention is to provide a kind of ink jet ink for printing, and this ink has the characteristics of high hiding rare, low-transmittance.
