Nov 06, 2017

Whether it is a general offset printing ink or bright fast dry ink, there is a problem of improving drying. Ink drying refers to the ink printed on the paper, due to the absorption of paper and the volatile ink solvent, so that the ink solid on the surface of the paper, without strong embossing or friction will not be on the back of the paper sticky performance.Green Offset Printing Ink 

Ink drying and ink manufacturing process technology and formula, but also with the printing equipment and printing technology. More than 10 years ago, most of China's Offsctdruckereien inks used rosin modified phenolic resin as the main binders, commonly used is bisphenol A and P-tert-butyl phenol technology route.Green Offset Printing Ink

In recent years, the use of the technology of phenol or phenyl phenol to improve the release of mineral oil, thereby improving the retention of ink. More than 10 years ago, the ink generally takes about 15 minutes to dry to solid, now only 10 minutes or even shorter time can be dried solid, the index has reached the best level of similar products abroad.Green Offset Printing Ink

Because the initial solidification drying time of the ink shorten, it also shortens the later period of oxidation of conjunctival drying time. In addition, in environmental protection, the use of aromatics-free or less aromatic solvents to reduce the harm to the human body, and this solvent on the ink solid drying has a clear accelerated role.Green Offset Printing Ink

Offset printing ink Another product-not conjunctival inks in the use of the process can be guaranteed within 48 hours (individual manufacturers do not reach) in the rollers do not crust, intermediate downtime also does not affect the printing quality, and does not affect the ink retention drying time, also does not affect the late oxidation of conjunctival drying effect, reduce the waste of cleaning inks, saving ink, Now it's a mature technology.Green Offset Printing Ink
