The classification ink
If the color-based classification, ink can be divided into :
Dye-based ink that is ----- dye to color-ink, is currently the most used inkjet printer ink.
----- Pigment-ink pigment is the base for color ink.
If the ink is to distinguish between solvent, classified as :
Waterborne Mexican ----- water and the water-soluble solvent dissolved as a base color of the major components.
----- Oily ink to the non-water-soluble solvent dissolved as a base color of the major components.
Over the concept in the actual process of the use of cross-cutting, such as paint-aqueous ink is ink can also be oily ink.
But from the very nature and the practical requirements for printers, ink and water oily ink is absolutely impermissible in a print header mix.
Ink impact Print and Print results of the first performance factors
General printer ink used by the quality of the following factors decision :
* Viscosity and surface tension : that the viscosity of the liquid flow resistance of liquid surface tension is related to the formation of droplets, in general, have an inkjet ink low viscosity, high surface tension, in order to ensure a good flow properties and droplets form.
* PH said liquid pH is the concept, the more acid solution, pH lower, on the contrary, the more alkaline solution, the higher the pH. To prevent corrosion nozzle ink, PH should normally be between 7-12.
* Conductivity : the ink, the conductivity value which is used to reflect the level of salt content. Generally, salt content must not exceed 0.5% of the nozzle to avoid crystallization.
* Dispersant : Surfactant is a, and its role is mainly to improve the ink surface of the physical properties, and the ink sponge enhance the compatibility, wettability. It is generally through the cavernous storage, conduction of ink contain dispersant.
