Inkjet printing can be classified in several ways, by application into the SOHO (small office, home office) and printing (WF); press technology is divided into thermal and piezoelectric. Also by printing mode is divided into continuous or select inkjet (DOD-Drop On Demand). Ink manufacturers are usually put into use inkjet aqueous and solvent resistance.Metal soap
In recent years, pigment-based ink jet technology acclaimed, primarily due to pigments and dyes generally performed better compared to water and light fastness. The current inkjet market, ink manufacturers and producers are increasingly demanding filling ink pigment pastes, including preparation, including a simple solution. Just added to the formulation of several of these additives and the "magic ingredient" ink jet printing can be made to meet the stringent requirements of high-performance ink jet printing. The following will explore both aqueous and solvent inks require fine pigment preparation.
Aqueous inkjet ink; Figure 1 describes a similar process for preparing an aqueous pigment, the first step is the right choice pigments. Inkjet printing usually requires black, red, blue, yellow four color combinations, so you must choose one kind of match with the desired color hue pigments. The water, dispersing agent and other additives such as pigment powder or wet cake was added after the mixing of the homogenized material and wet the pigment surface. Then the aggregates and agglomerates of the pigment particles are composed of a bead mill, a microfluidizer, or other suitable dispersing manner to that of primary particles.
Because the space between the molecules and the dispersion or electrostatic repulsion, native particles become very stable. The resulting pigment slurry was filtered, and by addition of water, a co-solvent (wetting agent), and other ingredients such as antimicrobial agents, chelating dilution. It must be emphasized, used in the first step of the pigment dispersed pigment channel technology influence.PVC impact modifier
