The glossiness, brightness, and wear resistance of the brightness problem, whether it is ink or ink are not related to the production process, the different types of ink, but in daily work, often asked whether the color brightness of ink is less than the ink, in fact This is the reason for the brightness of the pigment itself. Ink manufacturers choose this product for routine inspections. For example, most printing companies believe that the red color of the yellowish phase is brighter and brighter, and each printing company in the region has its own Like or popular colors, each ink factory has a variety of different brightness, transparent or translucent colors for your choice, so the brightness of the ink and the brightness of the ink without any difference.
Gloss and abrasion resistance generally refer to the basic requirements for printing ink or ink when printing on a gravure surface. The performance of ink in this area is far better than ink. If the gloss of the table printing ink is about 70 degrees at a 60 degree angle, the anti-sticking phenomenon will occur under a certain temperature and pressure. When the gloss of the ink is at a 90 degree angle of 60 degrees, it is not under the same conditions. There will be anti-sticking, ink wear resistance is higher than the surface printing ink (except for the two-component exception). The abrasion resistance of ordinary surface printing inks and waterborne surface inks are tested under the same conditions. The ink will show traces (completely decolorized) when it is rubbed for the second time, and the inks will appear slight after the ninth friction. Traces (standard for ten times). Therefore, the gloss and wear resistance of environmental protection inks are better than inks.
The printability of ink and ink for different substrates, as long as the surface treatment requirements, such as PE, PET, PA, B0PP, CPP, aluminized film, metal foil, pearl film, etc., just use the same ink printing can be . The ink is highly targeted. To print such a variety of substrates requires five different inks to cope with. The type of solvent is more than seven, which not only consumes a lot of money, but also increases inventory. , And increase the risk of the existence of a large number of inventories of solvents.
Other characteristics of water ink Water-based plastic composite ink and solvent-based composite ink difference is that the solvent-based composite ink is divided into ordinary composite ink, high temperature composite ink, the price from 17 yuan / Kg of low-grade composite ink, to 24 yuan / Kg About mid-range composite ink, to 40 ~ 50 yuan / Kg of high temperature composite ink, and aqueous composite ink can only use one to meet its basic requirements, the unit price of 30 yuan / Kg, the overall cost of 15 to 16 yuan /Kg or so.
After printing with water-based compound inks, there is no special requirement for what kind of compound glue is used for composite processes. Soft pack companies can use post-process work according to their usage habits.
High ink solid content, high color density, low viscosity, solid content between 38% ~ 58%, color concentration higher than the same type of ink 20% ~ 40%, printing viscosity in the range of 9 "~ 13", suitable for high speed print.
The ink and ink properties written above represent the technical level of the current environment-friendly plastic ink, and its use technology, cost accounting, market prospects, etc. will be stated separately. Lower-cost, second-generation green plastic ink that will meet the requirements of soft pack companies will be launched this year. It will bring new concepts to soft pack companies, new printing technologies, and low cost in one step. It will certainly enable soft pack companies to reduce printing costs and create greater economic benefits.
