New Metal Ink Is to use a large metal sheet metal ink particles reflect light Ershi with luster. Over the years, the metal ink is Mesh Print To produce metallic gold or silver sheen. Screen printing screen and print as slow bring the cost up, and metallic inks in the printing due to improper use, prone to poor ink drying, ink, and dull and so heap abuses. New metal ink is usually water-based UV ink and UV ink, the metal ink sheetfed offset press, or the use of flexo printing, can prevent the emergence of those abuses, but also necessary, to prepare the various colors. Metallic inks ( HC screen Special Indian network With map) Metal foil ink particles relies on reflected light Ershi with shiny metallic inks, foil large particles, then the reflected light and more, can better enhance the metal effect ink. Too fine metal particles, one prone to diffuse light, so that the loss of the metallic ink; second is easily oxidized, let alone produce a metallic luster. In screen printing, since the screen and the screen printing process of the limit, so that the metal sheet metal ink particles must not be too large. We all know, screen printing, the screen size of the mesh determines the accuracy of printed materials, but also determines the mesh size. The higher the mesh, mesh size smaller. The accuracy of printed materials need to aim high mesh screen, such as the mesh is too low, mesh is too large, the printed product will appear jagged marginal impact graphic precision. However, the mesh size is too small, the larger ink particles will be stopped the passage of time can cause serious reduction in the printing color density. Moreover, even without this happens, because too many particles in Screen, also make the ink scraping blade had to wash too many tablets together, so that the work would cause a standstill, it is worth the thing. Practice shows that the mesh size should be the average size of metal micro-chip is about 3 times more appropriate. At this point the metal sheet metal ink particles can be more smoothly under the action of scraper through the screen. General metal ink particles, the average size of 5 ~ 12 m, according to mesh size should be a piece of metal micro-about 3 times the average size of the principle of mesh used in the mesh up to 275L/cm (the mesh size 33 m) Obviously, the mesh with 275L/cm to printing, precision is not enough. New metal inks for sheetfed offset press, or can be used for flexographic printing presses, there is no objective limits screen mesh, so the metal sheet can be large particles, using a large metal sheet the role of particles to be more reflected light better enhance the metal effect ink, but because of metal micro-chip on the ink viscosity, making the metal flakes in metallic ink particles can not be too large. Metallic inks are usually known to us the organic pigment inks of different metal ink ink particles will not be improved through increased sophistication becomes viscous ink. This is mainly because the process of sheet metal produced in the flow of spin or swing, the required high-energy particles to be more common, larger micro-chip in the ink medium required a great thrust movement, so we should increase the viscosity of ink If the ink is too thick will result in uneven print density, and as a film phenomenon. In contrast, only a very small tiny microchip thrust, the mobile can achieve smooth natural viscosity Guer also show very low. Larger pieces of metal can better enhance the micro metallic ink results, but in order to obtain low viscosity and homogeneity of the effect of printing, they often require smaller microchip. Typically, the size ink sheet metal shape is not the same, to obtain a good printing effect, the new sheet metal ink particles mostly metal strip of micro-tablets, micro tablets of this shape to meet the size of the premise, can reduce the micro-chip in the ink media campaign thrust required to achieve the objective of reducing ink viscosity.
