Thermal transfer printing technology
Heat transfer printing refers to the transfer of the image and text on the intermediate carrier film to the substrate with the corresponding pressure, and according to the different pressure, heat transfer ribbon technology can be divided into water transfer, heat transfer, gas transfer, screen transfer, low temperature transfer, and so on.Thermal transfer is the portrait, landscape, etc. Any image using thermal transfer ink (that is, the sublimation print in color ink jet ink on paper (or special thermal sublimation inkjet printing paper), or the ordinary ink to print on the film thermal transfer paper, through the thermal transfer heat heating equipment in a few minutes to a certain temperature, put the paper on the patterns of the vivid picture of transfer printing to porcelain, glass, metal, plastic, cotton fabric and other material on a special printing process.
Since heat transfer printing is only a process, customers can shorten the work of printing patterns and reduce the loss of materials (finished products) caused by misprints.In other words, the use of heat transfer film printing can be a multi-color pattern into a diagram, no need for color, even with some simple equipment can be printed realistic patterns, thus greatly improving its applicable scope and realize the transfer operation.
Specification
Application
Thermal transfer film in the market there are many sizes, at that time with the size of 48*64cm sheet and 60*100m roll is more common, in addition to the thickness of 75U and 100U, 75U used in the plane CMYk transfer, but for thick plate transfer, it is recommended to use the thickness of 100U material, because its thickness can better bear the weight of thick plate.One caveat: Thick plate transfer prints are more often displayed on baseball caps because the effect is more prominent and the colors are brighter
Attention
①The conclusion of temperature: temperature is too low will appear hot stamping or hot stamping is not firm, but also make imprinted hair;The temperature is too high and will make the color layer appearance oxidation, make the product lose luster, the color becomes dark, severe will bubble.To determine the best hot stamping temperature should consider the following elements: pressure, speed, area, room temperature, etc.Hot stamping temperature in the general range of 140 ° C - 180 ° C, once the best temperature is determined, should adhere to the stability, the temperature difference in ±2 ° C should be shaken.
② Pressure determination: hot stamping pressure is generally 4-6 kg/cm2.Pressure is too small, can not make hot stamping film and substrate adhesion, reduce the fastness;If the pressure is too large, and will produce substrate compression deformation increase, forming speckle deformation, thin print layer.If hot stamping messy uneven products, more to pay attention to the uniform pressure point common, on the bronching wheel and substrate pressure Angle requirements higher, otherwise, easy to appear part of the firm, part of the phenomenon.
③ The conclusion of speed: should be based on the hot stamping area to determine, together to consider the heating temperature power.It is primary velocity commonly, decide pressure again, decide temperature finally.
Company workshop
Dongguan Cowint New Materials Co., Ltd. is a professional manufacturer of thermal transfer film and its materials, with many sets of advanced automatic production equipment, can customize thermal transfer materials of different sizes and requirements for customers
Heat transfer film production process (Preparation of raw materials)
A. Preparation of substrate film
There are many kinds of heat transfer film carriers, the most widely used is PET, it has good dimensional stability, uniform tension, good heat resistance, good release.In particular, it has obvious advantages in the reproduction of chromatic gradient manuscripts.The film specifications such as width, thickness dimension and brand are selected according to the manufacturer's requirements.At the same time to check the film flatness, tube material whether there is "tendon", "lotus leaf edge" and other non-quality requirements.
B. Preparation of release agent
Mold release agent is a kind of mold, film and adhesive properties of the transparent resin of low viscosity, because the mold release agent in the solvent evaporation speed faster, so in the coating process, attention should be paid to control the viscosity, which control the solid content of the mold release agent, solid content is generally controlled at about 23%, if the solid content is below 19%, coating and mold release agent of thermal transfer film after transfer printing effect is not ideal.Also pay attention to the transparency of release agent, otherwise it will affect the effect of the printing layer.
C, Ink preparation
Heat transfer printing ink belongs to gravure printing ink, ink drying mainly depends on the volatile solvent, substrate film is determined, according to the use of printed matter and the nature of the substrate material or according to the requirements of the construction sheet to choose the appropriate ink.Check the ink fineness, viscosity, color, colouring power and other indicators, to see whether all meet the printing quality of the ink requirements.
D. Preparation of adhesive
Heat transfer printing with adhesives for hot melt adhesive, is colorless transparent or light yellow viscous liquid, coating dry film, film is transparent, in the coating good release agent and ink surface has excellent compound fastness and excellent flexibility, abrasion resistance, water resistance and acid and alkali and other medium ability, good weather resistance.
