Printer Ink - Regular

Printer Ink
- A pigmented liquid or paste
- A dark liquid ejected for protection by most cephalopods, including the octopus and squid
- A dispersion of a pigment or a solution of a dye in a carrier vehicle, yielding a fluid, paste, or powder to be applied to and dried on a substrate
- Fundamentally, inks are composed of four major material categories: (1) Colorants (which include pigments, toners, and dyes) provide the color contrast with the substrate. (2) Vehicles, or varnishes, act as carriers for the colorants during the printing operation. Upon drying, the vehicles bind the colorants to the substrate. (3) Additives influence the printability, film characteristics, drying speed, and end-use properties. (4) Solvents (including water), besides participating in formation of the vehicles, are used to reduce ink viscosity and adjust drying ease and resin compatibility. Ingredients from these four classes are weighed, mixed, and ground (dispersed) together or separately, according to the formulas preestablished in the laboratory

Health Aspect
- There is a misconception that ink isn't harmful even if swallowed. Once ingested, ink can be hazardous to one's health. Certain inks, such as those used in printers, and even those found in a common pen can be harmful. Though ink will not cause death, inappropriate contact can cause effects such as severe headaches, skin irritation, or nervous system damage. These effects can be caused by solvents or by pigment constituents such as p-Anisidine, which is used in the process of creating the ink's color and shine. The poison control center has stated that any consumption of ink should be reported to a local hospital or poison control center
Environmental Aspect
- Recycled ink and toner cartridges reduce its environmental impacts
- Dry ink printers generate 90% less waste than laser printers
- Buy recycled, Use recycled, Send to recycling
