From the traditional glass screen printing to the emerging of leds, touch panel, printing, screen printing technology throughout the glass industry, and play an important role in it.
As one of the important areas for screen printing industry, glass screen printing in the printing industry how plays important role?
Introduction to the glass screen printing technology
     Glass screen printing, is to use silk screen printing, the use of glass glaze, decorative printing on the glass.Glass glaze is also called glass printing ink, glass printing material, it is by the coloring material, links mixture and stir paste printing material.Coloring material by inorganic pigments, low melting flux (lead glass powder);Link is commonly known as for suet in glass screen printing industry.After printing glass products, to put in the furnace, in the temperature of 520 ~ 600 ℃ fire, printed on the surface of glass glaze on the glass to consolidation, form the colorful decorative pattern.If the screen printing and other processing methods and use of words, will give a more ideal result.For example, using methods such as polishing, engraving, corrosion in printing before or after processing was carried out on the glass surface, able to improve the effect of printing double.
The application scope of glass screen printing technology
      Application and market prospect of screen printing plate glass screen printing plate glass is widely used in every corner of our life: you can in the display window, building space partition, building appearance beautification, the place such as car windshields and Mosaic glass easily find them.At the same time. They are widely used in furniture decoration and game tools, as well as countless decorative and artistic creation.Screen printing has been become a part of the glass manufacturing creative design work.People can through the screen printing printing color image directly into the glass surface.In addition, it can also be used to cover for the time being no picture and text part of the glass surface, or in the area of the printing on the surface of the glass preservatives such as additives, make it not influenced by etching or grinding process.Relatively, can also direct special screen printing ink, producing etched or frosted effect.Sometimes.People will use the screen printing cover ability strong, such as on the glass printed on a thin layer of conductive material, used to make the window of the deicing device (cream).

     Screen printing expanding in the field of flat glass decoration.Except for its applicable to all kinds of substrates, another important factor is that it can meet in a wide range of different size and weight of flat glass substrates.And, as a result of screen printing in large format images of absolute advantage, strengthened its leading the development of the whole flat glass printing industry leading position.Especially in recent years, the demand of large plate glass printing sharply rising trend.In fact, as a result of screen printing in the rapid development in the field of large plate glass decoration, printing equipment manufacturers are also continue to improve, to adapt to the increasingly demanding of printing, such as flat glass, and other fields, in particular, causing many of the world's most flexible printing equipment is widely applied in construction.In the screen printing plate glass decorative applications will continue to develop, expanding its application field in glass decoration.Screen printing machine with substrate transfer system, faster, and more advanced power system, the joint powerful PLC (logic control unit)
In addition, the auto industry demand for glass screen printing technology is also very strong in addition to pure color optical applications use silk screen printing, all kinds of function layer (such as Windows after heat conductor) have also been modified conductive pathways and the best structure (such as the window after heating device) must be imprinted on the basis of stable in time, and ensure the excellent quality.
     Glass detection technology has attracted much attention
    The Shanghai glass show, we noticed another outstanding characteristic is the technology and equipment of the glass test received the widespread attention of people, especially for some high technology value-added glass screen printing products, such as LED, touch screen and the automobile glass, solar energy substrate, and so on.These products have strict requirements on quality and yield, so with the development of science and technology, more and more glass screen printing enterprises began to focus on and to control the quality of the finished product, glass making glass detection technology become another hot area nowadays glass industry.
Then the glass screen printing technology, tend to occur in the manufacturing process of the quality problem?
Glass screen printing process prone to problems

Paste version
      1.Paste version also called blocking version "refers to the screen plate by hole section in the printing ink can not be transferred to the phenomenon on the substrates.The emergence of this phenomenon will affect the print quality, serious when even can't be normal print.Occurring in the process of silk screen printing paste version phenomenon the reason is complicated.Paste version of the reason is analyzed from the following aspects: (1) the cause of the glass, glass clean surface without treatment, there is watermark, paper, printing, publishing, fingerprints, dust, dirt particles, etc.Thus cause paste version;The reason that the workshop temperature, humidity and the nature of the ink (2).Silk screen printing workshop requirements to keep a certain temperature around 20 ℃ and relative humidity of 50%, if the temperature is high, the relative humidity is low, the volatile solvent ink will quickly evaporate, silk screen printing ink on high viscosity, which block the mesh.Another point should be noted that if the downtime is too long, also can produce paste version phenomenon, the longer the more serious the paste version.Second, if the environment temperature is low, ink illiquid also prone to paste version;(3) the cause of the silk screen plate.Making good screen plate rinse clean and dry before using rear can use.If placed too long after making good version printing not in time.In the preservation process will be more or less dust on adhesion, printing if not clean, can cause the paste version.(4) the reason of printing pressure.Printing process medium pressure seal force is too large, can make the scraper, scraper with silk screen printing plate and the glass is not a line contact, the surface contact, each scrapping printing ink to shave, and leave a residual ink, after a certain time will paste version of the conjunctiva.(5) silk screen printing plate and glass improper clearance.Screen plate clearance between glass and not too small, too small clearance after scrapping printing screen version can in time out of glass, silk screen plate to lift, at the bottom of the plate must be ink stick, so also easy to cause the paste board.6. The cause of the ink, in the silk screen printing ink pigments and other solid particles is larger, is prone to the phenomenon of plug mesh.In addition, the selected number of wire mesh and hole area is small compared to the ink granularity, ink is not easy to make the coarser particles through the mesh and censorship occur also is one of the reasons.Of caused by ink particles larger paste version, can make ink from the address, the main method is to strictly control the fineness of the ink.
