Inkjet technology and the printing flexibility it offers is enabling a rapid growth in industrial and commercial inkjet printing. Modern inkjet print heads can be designed and configured to print on many different substrates, and can produce functional 3D structures as well as 2D images. The inks used for a specific application must meet certain criteria; firstly they must be printable and secondly they must produce the desired decorative effect or functionality when printed. These two important criteria are related to the properties of the ink formulation and the properties of the dispersed pigment.
In the first webinar of our three part series, we focus on the importance of particle size measurements for evaluating and controlling pigment size and stability during the milling process. The particle size of pigments or other solid component is critical in determining the properties of the products in which they are used including opacity, color, hue, tinting strength, gloss, durability and also ink viscosity.
