The subdivision of heat transfer (thermal transfer) can be divided into industrial heat transfer and inkjet heat transfer. Industrial heat transfer is suitable for batch operation. It needs to be printed with a large-scale printing machine. The start-up fee and plate-making fee are relatively high. Usually this process can be used for at least 100 copies, otherwise the cost is too high. The proofing fee is usually several hundred yuan. Inkjet heat transfer refers to the need for an inkjet printer to print on special transfer paper, which can be printed in a single piece, so the proofing cost is very cheap, only a few tens of yuan, suitable for small workshops in the family. However, this process is inefficient and the resolution is slightly inferior to the process heat transfer, and it is not suitable for the printing of dark clothes.
The principle of dot color printing: dot color printing is actually a type of screen printing, but it uses too many dots to form a pattern. In this method, the excessive color is expressed by the density of the dots. The thinner the dots, the lighter the color, and the darker the converse. Through the superposition of multiple sets of dots such as C, M, Y, K to form colorful transitional colors and complex color patterns.
Dot screen printing advantages: good color fastness. The pattern is soft and natural. Can basically express the gradient color, excessive color.
Insufficient screen printing of dots: When expressing very delicate portraits and 3D game patterns, excessive colors are not fine enough to see dots, and there is more than 20% color difference.
Principle of heat transfer thermal transfer: first print or print the pattern on special paper, and then "stick" or "stick" the special paper to the clothes through high temperature, so this process is also called heat transfer, heat transfer, transfer printing , Digital thermal transfer, etc.
Advantages of heat transfer: it can print high-precision character photos, 3D game patterns and other very complex, excessively delicate patterns, which can be very close to computer design drafts.
Disadvantages of heat transfer: the fastness is a little low, like a piece of leather, it has a plastic feel. It is not suitable for making large-format patterns, because it will be too breathable and a little boring. The larger the pattern, the easier the corners to lift and fall off. It is also not resistant to washing. If it is washed in the washing machine, it will easily fall off locally. It is recommended not to use this process for long-term wear. If you wear it for a long time and can compromise the color and fineness, it is more appropriate to use dot color printing.
