The form of heat transfer printing is to transfer the text and text printed on the carrier film on the surface of plastic products, fabrics and other goods through heating and pressure, the process can be divided into two parts: heat transfer film production and transfer processing.So, what are the advantages of heat transfer process?
First, graphics and texts have durability
Most plastic products are durable, which requires that the pictures and pictures on the printing must be durable.Using heat transfer printing method, its graphic and text and plastic surface bonding firm, smooth surface, wear resistance and weather resistance can be good, and by adjusting the production formula of heat transfer printing film can also meet some special requirements, such as acid and alkali resistance requirements.Therefore, thermal transfer printing on the text and text with plastic products almost synchronous durability.
Second, improve the grade of plastic products
Plastic surface decoration and decoration, can use a variety of printing methods, such as screen printing, pad printing, hot stamping, etc.Although these methods have their own advantages, they also have their own disadvantages.For example, although screen printing can make graphic and text and plastic surface combination firm, not easy to peel, but the pattern is not clear enough, the dot is too thick, the surface is rough;Pad printing decoration area is too small;And hot stamping temperature requirements are very high.The method of heat transfer printing can overcome the shortcomings of these printing methods.At present, almost all the plastic thermal transfer film use the gravure printing method for graphic, when by heat transfer to the plastic products on the surface, compared with the other printing method, it shows a high precision, stereo sense is strong, rich layers, the characteristics of colorful, photo like the picture quality can be obtained, thus greatly improve the grade of plastic products, increase the value of goods.
The processing process is pollution-free
The operation process of transferring pictures and texts on the transfer film to the surface of plastic products is simple and fast, and the one-time transfer is completed without pollution.Pre-employment training for workers does not take much time.Heat transfer printing machine can be used with plastic injection molding machine at the same time, it can be used to inject plastic products at the same time, while heat transfer printing text and text and packaging products, forming a reasonable and efficient production process.
Expand the application range of printing
With the help of the heat transfer machine, the heat transfer film can decorate the plastic products of various shapes (such as plane, cylinder, polygon, cone, etc.), which is widely used in the surface printing of plastic products that is difficult to print directly, especially the printing of plastic products of different shapes that need multi-color printing effect.For example, to be on a triangular shape cup or a small penholder printing colorful, rich layers of patterns, heat transfer printing is the best decoration method.
