Talking about the performance index of flexible printing ink

First of all, the new acrylic type flexographic water-based inks can completely replace the alcohol-soluble flexographic inks in terms of fineness, brightness, adhesion fastness, fluidity, surface dryness other indicators, the printability is very good. Except for water-based inks with modified resin as connecting material, the adhesion water resistance of water-based inks with rosin modified resin as connecting material are very poor. This type of water-based ink can only print low-grade kraft paper, corrugated paper less demanding cement bags However, the drying speed printing suitability of this type of water-based ink are acceptable. It can be redissolved in water after drying (because this type of water-based ink is resistant to water after drying), it is necessary to clean the plate immediately after stopping during the printing process.

The new acrylic water-based ink is very good for printing paper, plastic, non-woven fabrics, etc. After printing, the brightness, adhesion water resistance are very good, because this type of water-based ink is very water-resistant after drying (soaked in tap water for 48 Hours do fade), so for this type of water-based inks to stop for a long time during the printing process, you must clean the plate the ink roller with clean water. Once the ink film is dry, you must use a special plate-washing liquid to clean, otherwise dry on the plate No ink will be applied when printing again.

Secondly; water-based ink itself is weakly alkaline, so in terms of acid alkali resistance, it is only resistant to weak acids weak alkalis, which is worthy of everyone's attention. Here I remind everyone to pay attention to the details when using water-based inks to print use correctly
