Inks, pigments, dyes

Inks are strongly tinted liquid or pasty substances used to mark paper and all other printable materials.
Made up of dissolved dyes which impregnate or bite the support such as dyes, or dispersions of pigments in a binder such as paints, from which they are distinguished only by their use.

  • Dye-based inks diffuse little light resulting in saturated and vivid colors when printed. This ink allows excellent color dispersion, thus preserving the glossy appearance of the support.
  • Pigment inks are much less fluid, they adhere and dry quickly without ever penetrating the substrate. With this type of ink, it is also possible to play with colors, shades, gradients… The precision is better than printing with dye inks.
