How is glass screen printing ink classified?

As we all know, silk screen glass materials mainly include silk screen, mesh frame, ink, etc. Among them, ink is necessary for silk screen printing. Without ink, there would be no pattern. Next, let's talk about which types of silk screen ink can be classified according to their different characteristics.

According to the processing temperature, it can be divided into:
1. Ordinary glass ink: Natural drying, surface drying time is about 30 minutes, actual drying time is about 18 hours. Suitable for printing various types of glass and polyester adhesive paper.
2. High temperature glass ink: also known as high-temperature tempered glass ink, with a sintering temperature of 720-850 ℃. After high-temperature tempering, the ink and glass are firmly fused together. Widely used in building curtain walls, automotive glass, household appliance glass, etc;
3. Low temperature glass ink: Concave convex plate and color crystal ink, baked at 100-150 ℃ for 15 minutes, with good ink adhesion and strong solvent resistance
4. Glass baking ink: High temperature baking, sintering temperature around 500 ℃. Widely used in industries such as glass, ceramics, and sports equipment.
5. Tempered glass ink: Tempered glass ink is strengthened by instant baking and instant cooling at high temperatures of 680 ℃ -720 ℃, which melts glass pigments and glass bodies into one, achieving color adhesion and durability. After coloring and strengthening, the glass has rich color, high structural strength, safety, and resistance to atmospheric corrosion. It has good corrosion resistance and covering power.

According to the solvent used for ink adjustment, it can be divided into:
1. Water based glass ink: Developed by Zhenbo Ink as one of the first successful batches, it is a non-toxic and organic solvent free glass ink that meets EU environmental standards. It is easy to clean and will not cause harm to personnel.
2. Oil glass ink: Due to the use of ink adjusting solvents and diluents, it has a strong irritating odor that evaporates. Long term use can cause significant physical harm to operators;

According to environmental standards, it can be divided into:
1. Lead containing glass ink: Ink pigments contain metallic substances such as chromium, nickel, and lead, which often pose certain pollution hazards.
2. Lead free environmentally friendly glass ink: Due to the use of ink pigments with relatively low lead content, it greatly reduces the harm of pollution, so it is often referred to as environmentally friendly glass ink.

The above is the classification of screen printing ink.
