What is ink made of?

Ink is a mixture of water, glycols, alcohols, various additives to achieve the necessary physical values and dye or pigments for the desired color. The development is slowly moving from dye to pigment inks. These are much more UV and water resistant, but not quite as high quality in terms of color brilliance.

There is no precise, generally applicable formulation for inkjet inks. The formulations vary from manufacturer to manufacturer and are adapted to the respective devices. Inks for inkjet printers must meet certain technical requirements that normal inks do not have to meet. For example, the ink must not dry up in the print head, but must dry extremely quickly on the paper. The corresponding values for the drying speed are only known to the manufacturers. Refill inks are available for most printers. However, you should find out about their lightfastness and color fidelity, which may differ from the properties of the more expensive original inks.

As a rule, they are similar in structure to fiber pen inks, with less humectant (about 5%). However, selected low-salt and lightfast dyes are used. For black ink, the major inkjet printer manufacturers usually use a pigment (Pigment Black 7) instead of a dye. This then has excellent lightfastness, water resistance and color depth. Direct Blue 199, Acid Yellow 9, Reactive Red 180, Acid Red 52, Direct Black 19, Pigment Black 7 can be used as colorants.
