Matsui Additives

What is an Additive?

An Additive is a substance added in small amounts to something else to improve, strengthen, or otherwise alter it. Additives are used for a variety of reasons. They are added to ink, for example, to enhance wash fastness or extend open time in the screen or to adjust viscosities.  Additives in our industry especially when printing water base are very helpful when used properly and as recommended.

Quick Additive

Mix 7-10% of Quick (All in One) Additive into ink to help extend the open time and keep the product from clogging in the screen. 35% humidity or above in your shop will also help extend the open time of water base inks, also better hand feel of a print.
