With the improvement of people's living standard, the public's aesthetic and consumption also have greater demand, the beautiful patterns printed on the glass products become more and more popular.Glass appearance and changeful, and silk screen printing can be printed on any of the substrates, so it is one of the best adornment method to screen printing.The application of screen printing on the glass provides consumers with a gorgeous not only beautiful image and exterior decoration with labels.After screen printing glass products popular, greatly satisfy the people's life and aesthetic needs, a variety of beautiful glass handicraft emerge in endlessly.

Glass screen printing

      So-called glass screen printing is to use network edition, cooperate to use glass glaze, printing on the glass.In comparison with the decoration of silk screen printing is applied to the glass on the application in other substrates some time later, in the 1970 s, our country appeared directly with curved surface screen printing glass processing factory.At the same time, the system mirror factory also started using flat screen printing technology.In recent years, with the ceramic stick paper gray water move decal popularization in ceramic processing, the processing technology gradually by reference to the adornment of the glass bottle.Moving screen printing color paper pattern to glass surface and high temperature treatment, after such decoration, instead of sticker label of glass bottles, glass screen printed products are improved, and the aesthetic value and market effect is much better.So many breweries have adapt, change the bottle label decoration.And with screen printing technology is gradually perfect, the advertising industry, automotive industry also began to use screen printing decorative glass.

Glass screen printing process

       The glass screen printing process according to the principle of silk screen printing, printing ink to the glass surface, and then USES the ink curing measures, printing design firm durable.Its technological process: glass - cutting - edge grinding - dry cleaning - printing - sintering.

      1. The requirements of substrates

      Is suitable for printing glass, the shape can be rules, also can be irregular shape, then pour edge grinding, cleaning, drying.Pay attention to the glass surface dry.

2. The screen to choose

      Of the screen at the beginning of glass printing plate with general screen plate, according to the difference of different substrates corresponding choice.Glass screen plate can choose silk screen, stainless steel wire mesh, synthetic fiber mesh.When ordinary printing ink, screen can be chosen, above generally selected physical and chemical properties of stability and low cost of synthetic fiber mesh.Net edition China open aperture size of choice depends on three aspects: (1) the first consider the ease of printing ink through the mesh.(2) the printing pattern design precision.(3) the surface roughness of substrates.

3. The choice of net frame

      First of all, according to the printing size and features chosen corresponding net frame, net frame consists of wood, metal and plastic box.Advantages: light quality, cheap price, conveniently;Defect is easy to deformation, accuracy and therefore should not be used as a multi-color screen printing, screen printing and high precision and can not make substantial net frame.Metal frame advantage is not easy deformation, the stress is strong, can be used as a multi-color screen printing and high precision screen printing;The disadvantage is that the price is high, our quality of transportation is not convenient, encounter chemicals easy to rust, cut screen box side improper handling easier.Advantage is high strength plastic mesh box, box Angle by the button is linked together, easy tear open outfit freely, strong corrosion resistance, moderate quality;The disadvantage is that the harmful composition in plastic can cause pollution to the environment, easy to burn.When choosing screen frame should be based on the characteristics of Internet box to select the most appropriate.

4. Net tense

5. Plate making

      Plate making equipment and material required by all have, you can process.Photographic pattern method is the direct method and indirect method, direct method, three kinds of technical indexes of plate making method is essentially the same, just coated photosensitive glue or lamination process method is different.Direct legal process: clean screen - drying - scraping gum - dry - exposure - development - drying - retouching - censorship - proofing - hardening treatment.Through the above process is a qualified screen is completed.

Glass printing

Above preparatory work is completed, you can use the computer printing

      Must be noticed when printing glass color printing color sequence: and don't usually transparent substrates of different color series, glass is transparent objects, so the printing color sequence is the opposite of printing opaque objects.
