How to distinguish the material of special paper?
The above is only a general concept, we usually say that now the offset may be more narrow in scope, namely the three roller (printing, lithographic printing, embossing blanket), in the south of our country to the printing mode called offset printing. The fabrication process of UV screen printing, printing name card printing to the surface will UV light oil over the film screen, and then through the UV light solid machine ultraviolet radiation, so that the light oil instant dry, forming surface projection light, play a prominent role in local graphics or patterns.
The rubber is heated by the name card, name card in the protective layer surface mounted coated with a layer of plastic material, laser print name card early, is accomplished by plastic + plastic film, the cost is relatively high, the important is to increase the stiffness of the name card. Now the four-color printing paper with name card are generally large +BOPP film laminating machine to complete the film, BOPP film and film of dumb light, generally used for name card, dumb film used more, the main role is to improve the grade and handle name card.
Special general name card are all types of paper are many exquisite patterns and various color materials there is PVC 0.38 the thickness of a transparent and matte black name card offset printing is a lithographic printing, very simple means of speaking that is offset rubber (Pib) will be transferred to the plate substrate printing mode is the existence of Pib, named after the printing mode. The blanket has played an irreplaceable role in the printing process, such as: it can make up for a good substrate surface is not flat, so that the full transfer of ink, it can reduce the plate of water (see water in the role in printing) to the substrate transfer etc..
