Pad printing inks are still dominated by solvent-based inks. Pad printing inks have been replaced with screen printing inks, and the effect is also very good. At present, most ink manufacturers treat pad printing inks and screen printing inks as one series . However, screen printing inks used in the pad printing process also have many problems. MARABU has pioneered the development of pad printing inks. In contrast, dedicated pad printing inks dry faster and more stable, and have better thixotropy. The ink layer of the pad printing process is relatively thin. To obtain more striking handwriting, the pigment purity in the ink is higher and the fineness is finer. These are the difficulties in manufacturing pad printing ink.
At present, in addition to MARABU company's special series of pad printing inks, German DUJO company's pad printing inks have begun to occupy a certain market. In addition, there are very few special printing inks, and the British COATES ink, which is famous for the production of screen printing inks, also has a large market share as an alternative to low-end products.
The printing ink market is vast and profitable, attracting the research and development of many domestic companies. The domestic ink production has recently developed very rapidly. The prominent ones are Zhongshan Zhongyi Ink Co., Ltd., Hangzhou Kewang Ink Co., Ltd., and Shenzhen Miramar Ink Ltd. etc.
UV ink has long been common in the field of screen printing, and now a final bastion is that UV printing inks can not be replaced with screen printing inks like solvent-based inks. The production process of UV screen printing ink is much simpler, as long as the ink permeability is good, the printing effect is easily guaranteed, and the UV pad printing ink requires the transfer of the pad to the acrylic resin monomer in the ink Well, generally speaking, the pads are made of silicone rubber, the affinity of silicone rubber and acrylic resin unit monomer is very poor, the transfer efficiency will be affected, on the other hand, the solvent ink must be added with necessary fillers to improve The trimming and trimming of the imprint, but UV pad printing ink can not add too much such filler, in addition to affecting the curing efficiency, the transparency of the ink will be difficult to guarantee: when developing UV pad printing ink, to ensure the color It is difficult to ensure a high concentration but ensure good transparency and good transferability. Now these problems have been overcome. MARABU, a professional manufacturer of pad printing inks, has fully launched their UV pad printing ink TPC series to the market.
The successful development of UV pad printing inks has solved some problems that have always troubled people. For a long time, the requirements of gloss and wear resistance of the text of computer keyboards have not met the requirements of customers. The use of UV inks has become the goal pursued by many manufacturers. However, printing UV inks by screen printing has a lot of troubles and is now used. The method of pad printing completes the transfer of UV ink, which can easily meet the requirements of customers. The characteristic of the pad printing process is to generate pressure from just above the substrate to complete the printing. Then, the printing process can easily prevent the product from shaking.
The product is mainly used as a food flavouring material, also used as a biochemical reagent and raw material for fermentation, and is also an amino acid drug.
