Water Based Printing Ink Formulation

These latest developments offer considerable advantages over traditional dispersions.

Water based printing ink formulation. On the other hand promoted by voc legislation and health issues water based inks were presented as an alternative to polluting organic solvent based formulations. Here s an overview of the wide ar. In this study the design of experiment used is a mixture design where three components of an original water based ink formulation are used as variables prior to the mixture design the original formulation was initially modified by adjusting the fraction of the emulsion polymer the wax and. In water based formulations two.

But there are a few different varieties of water based ink that make up the full list. From ready for use rfu inks to newer formulations like high solid acrylic hsa inks. Typical flexo gravure ink formulation. Terence kenneth will share how to best combine latest generation of raw materials biobased sma resins others to achieve the desired wb inks.

Polymers in emulsion or dispersion which improve the drying gloss adhesion and. One vehicle is solely based on emulsion polymer another contains solution polymer and the third is a 50 50 blend of these two. Basf has expanded the dispersions product line for the formulation of water based inks for printing on non absorbent substrates for flexible packaging. Table 1 shows the identity of the different components of the ink formulations.

Formulation 70 ratings formulate water based printing inks that equal solvent borne inks performance and avoid issues like slow drying foaming tendency poor press stability. These co solvents typically are voc s. The commercial water based inks that were used in both studies vary in type of pigment and acrylate polymer vehicle and in pigment vehicle mixing proportions. A water based ink is an ink that has either the pigments or the dyes in a colloidal suspension in a solvent with the solvent being water.

Besides eco efficiency and cost effectiveness the improved performance in terms of resolubility resistance and adhesion was confirmed in tests carried out with supply chain partners and presented at print4all. The simple answer is that water based ink is any ink which uses water as a solvent base to carry the pigment. Water resistance of inks. Polymers in solution which improve pigment wetting and make re solubilising.
