Flexographic inks

Flexographic inks are very similar to packaging gravure printing inks in that they are fast drying and have a low viscosity. The inks are formulated to lie on the surface of nonabsorbent substrates and solidify when solvents are removed. Solvents are removed with heat, unless U.V. curable inks are used.

These inks consist of colorants, which may be pigments and soluble dyes along with a binder and various solvents. Both Solvent based and water based inks commonly contain various types alcohol as the primary solvent or drier. Alcohol rapidly dries through evaporation and contributes to VOC emissions. The inks may also contain glycol ether and/or ammonia which facilitates drying.

The HYDROCRYL is a water-based ink used in corrugated boxes, both brown Kraft and top white liners for packing all types of items.

The FLEXOL is a water-based ink used in a wide variety of paper, like notebooks and paper-pad liners.
