As one of the indispensable important materials for printing adhesive label , its quality and usage are related to the printing effect of adhesive label. Therefore, on the basis of selecting high-quality ink, it is very important to master the use of ink.
1, the viscosity of the ink must be determined according to the printing speed, it is necessary to know that the ink has the characteristics of "thixotropy", when used to determine the viscosity according to the area of the printing plate and the speed of printing.
2, the use of the old ink, to use more than 80 mesh filter to filter out impurities and then use, in order to prevent the occurrence of quality failure;
3, in use, generally in the background overprint, the use of gradually increase the ink viscosity and gradually increase the ink PH method to help the ink dry, it also prevents the post-printed ink from muddy the already dried base ink.
4, in the adhesive label printing , ink bucket need to maintain a certain amount of ink, in order to achieve normal ink printing, so there will be a certain amount of residual ink, and the remaining ink do not continue to use, this may cause waste, increase its production costs.
5, due to the water-based ink is a liquid nature, and offset printing, embossing ink, it is prone to stratification or precipitation phenomenon, so in use or sampling, should be fully mixed ink evenly and then put into use, in order to ensure the stability of the printing color quality.
of course, there are many things to pay attention to in the use of ink. improper use of ink is likely to lead to poor printing effect of self-adhesive label , so special attention is needed.

Break down technical barriers! China's inkjet print head can no longer rely on foreign technology
A few days ago, the ZTE incident came to life after a storm. This crisis without gunpowder smoke has triggered a discussion among Chinese people about independent core technologies. In fact, in the 3D printing industry, there are many domestic technology subject to foreign, piezoelectric inkjet print head is one of them. China's "storm" strong counter-attack piezoelectric inkjet print head in the sand 3D printer, as the chip in the semiconductor, the importance is self-evident. Previously, companies such as German Voxeljet and Exone in the United States have already had relatively mature commercial applications in sand mold 3D printing technology, while Chinese companies limited to nozzles have few brands.

Digital printing will cross the label, rapid development in all areas of packaging
Mr. MichaelFairley believes that label processors still have time to find new business opportunities in the production of flexible packaging and folding cartons with their understanding, expertise and skills in digital printing. At the 2019 Asia International Label Printing Exhibition (LabelexpoAsia2019) held at the Shanghai New International Expo Center from December 3 to 6 this year, about 30 digital printing equipment-related manufacturers participated in the exhibition, including: u.S. Amica (Amica), Domino, Dilli, Haotian, Konica Minolta, Runtianzhi, Yunbo (Shanghai) Internet of Things Technology, Changzhou Temine, Hefei Runjie, Nebula Computer (GCC), Hanhua Industry, Saikang, Zhuo Jue, Dragan and Ningbo Worry, etc. Among these exhibitors, the use of inkjet technology accounts for the vast majority, thanks to the rapid development of nozzle technology, the improvement of printing materials and ink formulations, and the unprecedented progress made by color inkjet printers in terms of performance and market applications. The development of digital printing in the label industry has been more than 20 years. The first to enter this field was toner technology, followed by inkjet technology, and now Landa's nano digital printing technology. This is 20 years of rapid development. So far, the global label industry has installed about 4500 digital printing machines, of which HPIndigo and Saikang toner printing machines account for more than 2/3 of the total installed capacity.
