Ink material from the perspective of the development of printing technology in the Ming Dynasty has the following characteristics: ① multicolor multicolour technique has been developed; ② ink technology have made great progress; ③ printing technology to further expand the scope of use, books, newspapers, advertisements, letterheads The prints are all the famous Ming Dynasty; ④ movable type printed book is also a great development; ⑤ bindings widely used. Glass screen printing ink temperature performance reflects the temperature according to the firing of ceramic printing method can be divided into two types: one is initially at a temperature of 700 ~ 800 ℃ were unglazed PP ink wholesalers, after unglazed glazed and then fired at a temperature of 1100 ~ 1300 ℃. Heat resistant temperature of the ink in this manner of firing required to achieve 1100 ~ 1300 ℃; the other is to be fired at a high temperature 1100 ~ 1250 ℃ in, and then glazed to a temperature of 900 ~ 1000 ℃ firing. Such a heat resistant temperature of the ink is required to be lower than the former, reaches 900 ~ 1000 ℃. Used in conventional high temperature ceramic and glass ink, relatively high temperature heat, in the above anodization ink wholesalers 600 ℃, even more than 1000 ℃. While printing in some glass containers, sometimes low plating ink wholesalers than the heat resistant temperature of the ink on the use of ceramics, such as 180 ~ 200 ℃, this ink is also called low-temperature glass ink, with an organic coating and an organic pigment or imitation gold materials instead of inorganic pigments and gold made for decorative glass, baking 10min at 200 ℃. In the current temperature of the ink, the heat temperature of 1800 ~ 2000 ℃ less ink, if the request at this temperature for a long time baking, the ink can meet this requirement even less. Currently, about 200 ℃ temperature baking ability does not change color ink almost no domestic, mainly rely on imports, but foreign manufacturers who are relatively small, and the production of heat-resistant ink is not very stable, such as the wheel after printing labels, printing should at a temperature of 200 ℃ baking willing 3h, often discoloration, the application can meet the requirements of its relatively high cost of ink. Currently, some screen printing industry in developed countries have developed inks, product prices relatively high, so the ink has a high value, can replace similar imported ink, reducing printing costs of production.
