Ink & Printing
Ink is a liquid used to produce markings on a surface. Printing is the process of transferring ink from a printing press to a surface. The most common printing press is the offset lithographic press. Inks are made from colorants, solvents, resins, and fillers. The properties of inks and printing media are important factors in the quality of printed products. Colorfastness is the ability of a dye or pigment to resist fading when exposed to light or other environmental factors. Adhesion is the ability of ink to stick to a surface. Abrasion resistance is the ability of ink to resist being scratched or scraped off. Viscosity is the thickness of ink.
