Thermal transfer film refers to the pattern (actually refers to the graphics and text with release agent, protective layer and adhesive) printed on the surface of the film in advance. Under the combined action of heating and pressure, the graphics and text are separated from the carrier film, which is firm Special function printing film attached to the surface of the substrate.
High-definition heat transfer film is a new type of heat transfer film. It is a new type of heat transfer film with thick pattern ink layer, strong hiding power, high overprinting accuracy, high color reproduction, and excellent chemical resistance. The transfer film has the advantages of environmental protection, strong three-dimensional impression of the pattern after hot stamping, and variable data for personalized customized printing. Because the high-definition thermal transfer film adopts the method of full digital typesetting, there is no need to make a printing plate roller, which greatly reduces the cost burden of the manufacturer, and also greatly shortens the entire production cycle (the fastest delivery can be achieved within 24h); the production process adopts electronic Stable and reliable printing technology such as photography, realizing a true output of 1200dpi resolution and a four-digit variable dot density of 1200dpi×3600dpi, adding screen lines up to 240lpi, can print natural and realistic pure colors and mixed colors, and accurately restore clear , The details of Octavia. In order to distinguish it from the traditional thermal transfer film, it is called a high-definition thermal transfer film.
Routine application
The characteristics of thick ink layer and strong hiding power and its application examples
Once upon a time, dark-colored workpieces (substrates) were almost an unwilling area in the thermal transfer process. Due to the relatively thin ink layer of traditional thermal transfer, when the pattern is hot-stamped on the dark-colored workpiece, such things as Rejuvenation, discoloration, and penetration, among which discoloration is particularly serious. For example, when the pattern is hot-stamped on a dark red workpiece, the blue part of the pattern will become purple-red, and so on. According to the past process experience, a white pad between the pattern and the substrate is generally used to block the influence of the substrate’s background color on the pattern, and the darker the substrate color, the more layers of padding (up to three layers). Layer white), in addition to increasing the cost of plate making, it often increases the difficulty of pattern overprinting, which affects the quality of the flower film.
And now, with the advent of high-definition heat transfer film, this process problem is easily solved. The ink layer of the high-definition transfer film is mainly composed of printing toner. The thickness of the ink exhibition can reach about 30m. The formed pattern has full color, thick ink layer, strong three-dimensional effect, and high hiding power, which can meet the needs of business applications. Colored substrates have requirements for hiding power, even for dark-colored workpieces, the pattern can be perfectly reproduced.
The high-definition heat transfer film, with its unique full color, thick ink layer, and high hiding power, will eradicate the stubborn disease of dark workpieces that are easy to change color during the heat transfer process.
In addition, for some products originally printed by the screen printing (UV printing) process, after the pattern is formed, the surface of the pattern is required to have a certain touch, and it can also be completed by the high-definition thermal transfer process. Because the ink layer of the high-definition heat transfer film is relatively thick, the thickness of the ink layer is up to about 30μm, which is comparable to the thickness of the ink layer of screen printing (UV printing), and it can be packaged after printing and forming without taking up space for drying. Drying or curing greatly improves work efficiency.
