Detailed printing of thermal transfer technology on metal

With the increasing popularity of fashionable handicrafts, a variety of transfer technologies for handicrafts have also been developed, attracting entrepreneurs and fashion owners. Among them, the most known transfer technology is the two kinds of water transfer and thermal transfer. What is thermal transfer technology? What are its characteristics and uses? How about the transfer operation and market demand? Below we continue to explore.

First, thermal transfer technology

Transfer refers to a printing method in which the graphic image on the intermediate carrier film is transferred to the substrate with a corresponding pressure. According to different pressures, the transfer can be divided into water transfer printing, thermal transfer printing, and air transfer printing. Screen transfer, low temperature transfer, etc. Among them, thermal transfer is the use of thermal transfer inks (ie, sublimation inks) for printing arbitrary images such as portraits and landscapes on a color inkjet paper (or a sublimation special inkjet paper), or the ordinary ink is printed on the film heat. The transfer paper is then heated by a thermal transfer heating device to a certain temperature within a few minutes, and the pattern colors on the paper are transferred to a special type of material such as porcelain, glass, metal, plastic, and cotton fabrics. Process.

It can be seen that using thermal transfer technology, even for patterns of multiple colors, since the thermal transfer process is only a process, customers can shorten the work of printing patterns and reduce the loss of materials (finished products) due to printing errors. In other words, a multicolor pattern can be patterned at a time using thermal transfer film printing. No color registration is required, and even a simple device can be used to print a realistic pattern. This greatly increases the scope of application and realizes the transfer. Operation.

Second, production tools and implementation process

The use of thermal transfer technology can be widely applied to objects such as porcelain, glass, metal, plastics, and cotton textiles, but thermal transfer is limited by the heated area and the shape of the article, so it is often required for articles with different areas and shapes. The use of specific production tools, of which the current common heat transfer production tools are mainly flat-panel machines (hot stamping machine), baking pan machine, baking cup machine and so on, but after all, their production methods are based on the principle of thermal transfer, So its production steps and processes are similar, but the application of thermal transfer tools is different. The following uses the tablet transfer image to clothes as an example to illustrate the steps and flow of thermal transfer printing.

The first step: print the image through a color inkjet printer.

Step 2: The printed pattern is placed on the side first, and the transfer begins about 15 to 20 minutes later. During transfer, when the printed image is placed on the garment, the pattern should be face down, then adjust the time (usually 20 seconds) according to the requirements of the thermal transfer equipment transfer, and close the device heating plate ( Note: Before the transfer of pure cotton T-shirts should be sprayed with a little deepening agent at the printing site, and must be dry before the thermal transfer, its role is to change the ink color by hot pressure, improve the effect of the ink on the clothing ).

Step 3: In order to prevent the clothes from yellowing due to too high temperature, an interlining cloth may be put on the clothes before thermal transfer. After the time of the thermal transfer equipment is alarmed, lift the heater plate, quickly open the pattern paper, remove the clothes, and turn off the power of the device.

Step 4: At the end of the day, the temperature of the clothes is cooled, and the bag is folded to complete the entire heat transfer process and become a finished product.

Promotional   Paper Bags (Gift Bags) have many varieties of different type:

Press material can be divided into: white cardboard paper, white paper bags, art paper bags, Kraft paper bags, there is a small amount of specialty paper manufacturing.

This kind of Shopping Bags is easy to carry.

White Kraft paper: white Kraft paper bursting high toughness, high strength, evenness of thickness of the colored image stabilizer, according to relevant national laws and regulations restrict the use of supermarket Plastic Bags, as well as foreign countries, Europe and other countries to promote environmentally-friendly paper bag trend, and strictly control plastic pollution, plastic bags are environmentally friendly alternative to paper bags, white kraft paper market prospects. 100% pure pulp manufacturing, environmental protection, non-toxic, environmentally friendly recycling, white Kraft paper toughness good, but do not film, is widely used in the production of environmentally friendly garment bag, upscale shopping bags.

Common thickness of 120 g -300 grams of brown kraft. Kraft paper is generally suitable for printing monochrome or color and the color is not complex manuscript. With respect to the white cardboard, white paper box coated paper, yellow Kraft paper lowest price.

Duplex board paper Shopping Bags: white paper is a positive white and smooth, mostly on the back of the duplex cardboard, common thickness of 250 g -350 grams of white paper side is white, one side is gray, relatively inexpensive white paper jams a little.

Black cardboard Kraft Promotional Paper Bag: as a specialty paper, double-sided black. Black cardboard paper is characterized by delicate, transparent black heart, strong thick, good folding, smooth surface, good stiffness, good tensile, high resistance to breaking and the like. Common thickness of 120 g -350 grams of black cardboard. Because black cardboard inside and outside is black, so you can not print in color pattern is only suitable for bronzing, hot silver craft. Made out of the bag is very beautiful, oh.
