Abstract
The present invention discloses a technology for directly printing images on plate glass by an offset press. The present invention has the key technology that first, the surface of the plate glass is corroded by a glass fiber processing agent; then, the surface of the plate glass is reduced by a reducing agent, so a layer of uniform particles which can not be seen with the naked eyes is formed on the surface of the plate glass, and the ink adsorption force of the plate glass is enhanced. Thus, the printed images have the advantages of vivid colors, sharp levels and clear transparence, and products of the present invention have the advantages of moisture prevention, heat resistance, weak acid resistance, weak alkali resistance, etc. The present invention solves the problem that the offset press can not directly print the images on glass plates in the prior art, and the present invention fills the blanks of the printing technology in the world.
Description
The present invention relates to a kind of printing process, particularly a kind of with the direct method of printing picture picture on plate glass of offset press.
In prior art, plate transparent glass is carried out the printing of coloured image, generally all adopt silk screen print method, the portrait poor definition that this method prints, image is coarse, and tone is stiff, and the distortion factor is big.China's number of patent application is that 88108317.8 hectographic printing method produces that plate glass is drawn and the patent of wooden splint picture then goes a step further than silk screen print method, but its essence is the polyurethane film of at first on the surface of plate glass or wooden splint, coating layer of transparent, and then the required various colored inks of picture are printed on the film with the hectographic printing method.Although the portrait effect that prints in this way is better than silk screen print method, the percent reduction of portrait is higher, and definition is also good, but its fatal weakness is the influence that finished product is subjected to humid air, polyurethane film separates easily with plate glass, causes product percent of pass low.Simultaneously, because film surface is smooth, poor to the printing ink absorption affinity, printing ink is touched easily and is come off.Moreover, because this method has been coated with thin film and just prints epigraph on the plate glass face, therefore, with regard to many films of one deck woven design shape, influenced the definition of product and attractive in appearance on the surface of glass.According to the result for retrieval of document, do not have yet so far and find to utilize the hectographic printing method directly to be printed on method on the plate glass to portrait.
The purpose of this invention is to provide a kind of method that can directly on plate glass, carry out the printing picture picture with the hectographic printing method.
The present invention realizes in such a way: because glass surface is bright and clean level and smooth, do not absorb water, surperficial absorption affinity is poor, and printing ink can not directly be printed thereon face, for this reason, make glass can adsorb printing ink, must handle the surface of glass.Key of the present invention is exactly to adopt finishing agent for glass fibre-aminopropyltriethoxywerene werene or silicic acid to be coated on glass surface, and left standstill 2-3 hour, glass surface is carried out slight corrosion, reduces with oxalic acid solution then, at last with clear water glass rinse well, airing.Glass through above-mentioned processing, detect by an unaided eye, its surperficial transparency is the same with original glass with smoothness, feel also is as good as, but use microscopic examination, can find that then the surface of glass has been corroded into particulate marshalling, uniform, thereby strengthen the adsorption capacity of glass greatly printing ink, at this moment, utilize the hectographic printing method just can directly be printed on printing ink on the glass plate.In order to protect picture better, available prior art is coated with transparency materials such as last layer polyurethane lacquer or unsaturated polyester resin on the glass picture.Also the undressed clean glass of another piece that available size is identical is bonding and seal with the glassy phase that has printed picture with adhesive.Like this, glass-painting just can keep prolonged constant, attractive and durable.
With the glass-painting goods that the present invention produces, have bright in luster, well arranged, transparency is clear, printing ink combines firmly with glass, is not afraid of humidity, is not afraid of water logging, advantage such as heat-resisting, little alkali of weak acid resistant.
The present invention is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a process flow diagram of the present invention.
Embodiment 1, lie on the operating desk with clean plate glass, on glass surface, evenly be coated with layer of glass inorganic agent-aminopropyltriethoxywerene werene, and left standstill three hours, then glass plate is put into and filled the reduction cell that content is 30% oxalic acid solution, with hairbrush the silane compound of glass surface is cleaned up, again with clear water glass plate rinse well, airing, be available offset press the portrait that designs with ink printing on glass plate, behind the airing printing ink product.
Embodiment 2, and step is with embodiment 1, and just finishing agent for glass fibre is used silicic acid instead.
Claims (4)
1, a kind of method with direct method hectographic printing glass-painting is characterized in that plate glass will corrode 2-3 hour with finishing agent for glass fibre before offset printing, with the oxalic acid solution reduction, then with clear water cleaning, airing.
2, method according to claim 1 is characterized in that described finishing agent for glass fibre can be an aminopropyltriethoxywerene werene.
3, method according to claim 1 is characterized in that described finishing agent for glass fibre can be a silicic acid.
4, method according to claim 1 is characterized in that oxalic acid solution is meant that content is 30% oxalic acid solution.
