What are the temperature environment requirements for thermal transfer printing?

What are the features of thermal transfer machines that you don’t know? Thermal transfer processing machine uses thermal transfer ink to print any pictures such as portraits and landscapes on ordinary paper or high-precision printing paper, and then through some processes, the image on the paper is transferred to porcelain cups and porcelain cups with realistic colors. The writing on dishes, porcelain plates, clothes, etc. Let’s take a look at the characteristics of thermal transfer machines.

 Using a heat transfer machine, you can ensure beautiful pictures. Simple to use, one-time procedure, no need for steps such as color registration. The operation is simple and convenient, the printing work is exquisite and the cost is relatively low. It has strong adhesion and covering power. Compare and comply with green printing standards. What are the temperature environment requirements for thermal transfer printing? Different materials require different transfer temperatures. For plastics, the transfer temperature required for hard plastics (ABS, benzene, acrylic, etc.) is about 20°C lower than for soft plastics (PP, PE, etc.) . (The thermometer detects silicon and rollers, and the surface of the rubber plate is about 90℃-120℃), while the temperature required for PVC is lower (about 60℃-80℃). Since there is a layer of heat-resistant film between the heat source and the substrate during thermal transfer processing, and the contact time is not long (cot roller transfer is about 1cm/0.5-1 second, direct pressure of the rubber plate is about 1-4 seconds/time), It will basically not cause deformation of the printed object. However, if the printed object is a soft plastic plate less than 0.5mm, there will be a small amount of deformation.

Thermal transfer printing processing first requires a dust-free or less dusty environment at the production site to avoid dust spots falling on the substrate or transfer film surface, or defects on the pattern. The surface of the substrate must be free of oil stains, moisture, dust, and workers Wear pure cotton gloves to take out the substrate during operation to keep it clean. Keep the air source of the transfer material dry. The water filter should be drained every day to ensure smooth air path and normal cylinder operation.
