Selection and printing points of high temperature transfer ink

selection and printing precautions of ink generally use special high temperature resistant ink on the market, Dai rujun, the managing director of Xinda group of the same factory, said, "bio based materials use corn, sugarcane, etc. as the source of starch to synthesize the series products of polylactic acid home, so as to avoid different types of ink reaction. We generally use imported se-ries900 series inks to reduce machine failure, and use special 355 # to open oil and water. Remember, during mass production, solvents (such as defoamers, oil repellents) cannot be added indiscriminately." If it is added, when the decal is well bonded with the product for high-temperature paint baking, the surface will focus and crack, and the bonded product will be reworked

when printing, 300 mesh wire should be selected to achieve the same tension, generally between 18-19n/cm. First print a white background, then dry it with a hair dryer, and then use sticky scotch tape or high viscosity transfer film to try to stick it to see if the ink adhesion is good, and the good ink will be firmly attached to the material. If it falls off as soon as it is stuck, and the transfer film is torn off when fitting the product, the printed patterns with high-end machine performance of Jinan new era assay instrument Co., Ltd. will stick together, causing the decal to be scrapped. Therefore, in the choice of ink, we must choose brand products with strong adhesion and high temperature resistance. We should first test and proofing, and then mass production. If the adhesion of the white background meets the requirements, the back is printed in yellow, red, blue and black. After all colors are printed, a soft breakthrough larger than the second line of white background film is used. Large film combiner and film integration technology are used to print one time of high-temperature varnish. After it is completely dried, it can be die-cut. Die cutting should be cut in half, then tear off the unwanted frame, and then turn the film up. The transfer film can be appropriately selected from low viscosity, medium viscosity and high viscosity, and then use a knife mold 3mm larger than the previous die cutting, and then cut it completely. Generally, cutting is selected without special requirements. When fitting the product, stick the decal on the required part, then gently tear up the rotating film, cover a layer of varnish around the decal with a spray gun, and then bake the paint to produce the finished product
