Water Based Printing Ink Formulation

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.

Water based printing ink formulation. 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. Polymers in emulsion or dispersion which improve the drying gloss adhesion and. Standard test methods for adhesion rub resistance and gloss were done on the printed polyethylene films.

In the case of water based pigment textile inks the carrier is mainly water 50 to 80 mixed with water soluble organic com pounds which are called co solvents and humectants based on their functions. Polymers in solution which improve pigment wetting and make re solubilising. Effectively reduce the amount of ink transferred water based inks have higher pigment concentrations by volume that solvent based inks. From ready for use rfu inks to newer formulations like high solid acrylic hsa inks.

Basf has expanded the dispersions product line for the formulation of water based inks for printing on non absorbent substrates for flexible packaging. All though the main solvent in water based inks is water there can also be other co solvents present. Quantitative methods for the assessment and evaluation of the three print properties were developed. 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.

Therefore less water based ink volume is required on the printing plate. Water resistance of inks. In water based formulations two. The simple answer is that water based ink is any ink which uses water as a solvent base to carry the pigment.

In water based inks two types of acrylic polymers are used. 3 water based inks have been in existence since around 2500 b c. Surface active agents surfactants especially emulsifi ers wetting and dispersing agents are used to emulsify and stabilize hydrophobic substances e g. Water based ink formulations containing wax surfactant and defoamer additives were prepared and printed on polyethylene film substrates.

These latest developments offer considerable advantages over traditional dispersions. But there are a few different varieties of water based ink that make up the full list. 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.
