Today, when fashionable handicrafts are becoming more and more popular with people, various transfer printing techniques for making handicrafts have also been developed, and they have attracted many entrepreneurs and fashion lovers to use. Among them, the most well-known transfer technology at present is water transfer and thermal transfer. Before the water transfer technology, we have related in the article "Small Funds Start Water Transfer Shops to Grasp Fashion and Personality". Introduction, but what is thermal transfer technology? What are its characteristics and uses? How about its transfer operation and market demand? Let's continue the discussion below.
1.Introduction to Thermal Transfer Technology
Transfer printing refers to a printing method in which the graphics and text on the intermediate carrier film are transferred to the substrate with corresponding pressure. According to the different pressures used, transfer can be divided into water transfer, thermal transfer, air transfer, and Screen transfer, low temperature transfer, etc. Among them, thermal transfer is the use of thermal transfer ink (ie sublimation ink) to print any image of portraits, landscapes, etc. on color inkjet paper (or special inkjet printing paper for thermal sublimation), or ordinary ink on film thermal The transfer paper is heated to a certain temperature within a few minutes by thermal transfer heating equipment, and the color of the pattern on the paper is realistically transferred to porcelain, glass, metal, plastic, cotton fabric and other materials. Craft.
It can be seen that the use of thermal transfer technology, even for patterns of multiple colors, because thermal transfer is only a process, so customers can shorten the work of printing patterns and reduce the loss of materials (finished products) caused by printing errors. In other words, the use of thermal transfer film printing can make a multi-color pattern into a picture at a time, without the need for color register, even with some simple equipment can also print realistic patterns, in this way, greatly improve its scope of application and achieve transfer Operate.
2:production tools and implementation process
The use of thermal transfer technology can be widely applied to objects made of porcelain, glass, metal, plastic, cotton textiles, etc. However, because thermal transfer is limited by the heated area and the shape of the object, it is often necessary for objects of different areas and shapes. Use specific production tools, among which the current common thermal transfer production tools are mainly flatbed machines (heat transfer machines), bakeware, cup baking machines, etc., but after all their production methods are based on the principle of thermal transfer. Therefore, the production steps and processes are the same, except that the thermal transfer tools used are different. The following uses a flatbed machine to transfer images to clothes as an example to illustrate the steps and processes of thermal transfer production.
Step 1: Print the image through a color inkjet printer.
Step 2: Put the printed pattern aside first, and start the transfer after about 15-20 minutes. When transferring, when putting the printed image on the clothes, the pattern should be facing down, and then adjust the time according to the transfer requirements of the thermal transfer equipment (usually 20 seconds), and close the heating plate of the equipment ( Note: The cotton T-shirt should be sprayed with a little darkening agent on the printing part before transfer, and it must be dried before thermal transfer. Its function is to change the color of the ink through thermal pressure and improve the bright effect of the ink on the clothes. ).
The third step: In order to prevent the clothes from turning yellow due to the high temperature, a piece of interlining cloth can be put on the clothes for thermal transfer. After the time alarm of the thermal transfer equipment, lift up the heating sheet, quickly uncover the pattern paper, take out the clothes, and turn off the power supply of the equipment.
The fourth step: Finally, when the temperature of the clothes cools down, fold them and pack them, and then the entire heat transfer printing can be completed and the finished product can be made.
3: Analysis of market demand for thermal transfer printing
Compared with the current fashionable and mainstream water transfer printing, what are the advantages and disadvantages of thermal transfer technology? Specifically, the production of water transfer printing is more flexible and convenient, and will not be limited by the area and shape of the object. It usually does not require special tools and equipment (just a piece of water transfer paper), so its applicable range is more It is widely used, and the production cost is lower than that of thermal transfer printing. It is very suitable for home users, small workshops, and fashion jewelry stores.
Due to the heat transfer of the image, the color of the finished image will be stronger than that of the water transfer, and it will not be easy to fade. It has corrosion resistance, impact resistance, aging resistance, abrasion resistance, high temperature resistance, and fire resistance. , It can maintain the characteristics of no color change for ten to several decades, so thermal transfer technology is especially suitable for electrical appliances, daily necessities, building materials and decorations that have special requirements for image retention. For example, thermal transfer technology can be used to print trademarks, barcodes, labels, etc. on commodities. It is precisely because of the advantages and disadvantages of thermal transfer technology that this technology is usually favored and used by jewelry stores, printing manufacturers, and building materials departments with a certain scale.
In terms of market demand, with the continuous development of the commodity economy, various manufacturers and departments have higher and higher requirements for the trademark, label and packaging beauty of their own products. For the printing industry, the concept of printing is no longer what people think of. Traditional paper is printed. From our daily necessities to office appliances, to products in various industries such as telecom, decoration, crafts, etc., we need more, better and more practical external packaging, and most of these packaging are realized by transfer printing. , So the transfer industry has a very broad and deep market space.
Although water transfer printing will have a greater advantage in the transfer industry due to its convenient and flexible production and low cost, especially small and fashionable products, such as electrical appliances and metal aluminum materials have a problem with high temperature and image storage time. For more demanding products, the effect that thermal transfer can achieve is incomparable with water transfer. Therefore, thermal transfer technology will win its corresponding advantages due to its low production cost, firm imaging, and long storage time. Market share, so its market prospects are still very broad, not even lost to water transfer printing. Of course, water transfer printing and thermal transfer printing have their own advantages, and they can even complement each other before, so friends in the transfer industry may wish to consider both.
