[7] Some users mix inks to create their own colours. Some combinations of inks may cause unexpected colour changes, even if the inks are from the same manufacturer.
The desired coating material is typically dissolved or suspended into a precursor solution or slurry (sometimes referred to as "ink") and delivered onto the surface of the substrate through a precise coating head known as a slot-die. The slot-die has a high aspect ratio outlet controlling the final delivery of the coating liquid onto the substrate.
Gel pens. Compared to other inks, gel ink has higher melting point viscosity, which supports a higher proportion of pigments in the medium.The pigments are typically copper phthalocyanine, carbon black and iron oxides, and the gel is made up of water and biopolymers, such as xanthan gum and tragacanth gum, as well as some types of polyacrylate thickeners.
These values are usually multiplied by 1.5 or 2 when one of the colors is black. The trap is not visible since the lighter color is spread underneath the—almost—opaque black.
