Nowadays, two main types of ink formulations are in use: dye based inks and pigmented inks.
As formulation is an important step in the printing process various projects are being carried out in our group.

One project deals with the preparation of new ink formulations with dyes and pigments using a liquid handling robot. The physical behaviour of these formulations is studied by high throughput screening on commercial and new substrates which are being designed for optimal performance.

Another project is to devise high throughput methodologies for covalently modifying pigment surfaces and test their improved performance in ink formulations

Pigments are useful materials in a number of applications. The surface properties of the pigments are an important factor in their performance. The aim is to devise high throughput methodologies for modifying pigments to change their solubility.

Pigments are widely used materials in inkjet inks and the surface properties of pigments are an important factor in their performance. The aims of this project are to devise methodologies for covalently modifying the surface of pigments. This could be done by adding different type of polymers which can enhance the performance of pigments in an ink.
