Warranties for ink for printer

Some printers only use pigment-based ink for printer . Pigment-based inks are more expensive than the more common dye-based inks. Dye-based inks are absorbed into the paper. Pigment-based inks, though, are made of tiny particles that sit on top of the paper. Epson was the first manufacturer to make a printer that uses pigment inks. Few people put much consideration into the type of ink the printer is using.


Pigment inks have their own unique advantages. The dye ink for printer used in most early inkjet printers exhibited signs of fading or shifts in color after a short period of time. When exposed to the Sun's rays, a dye based printed document could fade in a matter of days.
 
For graphic artists, the choice to switch to pigment inks was a no-brainer. Under the right conditions, pigment ink can last for over 200 years. Wilhelm Imaging Research verified that pigment ink can, indeed, be used for archiving.


It's important to note that the paper, called the substrate, is as important as the ink in measuring print life. Glossy papers, with their slick finishes, are usually the worst offenders in terms of print life, but any paper with so-called optical brighteners, normally used to make a paper's finish bright white, will have some issues with either ultraviolet light or atmospheric pollutants.
 
Wilhelm Research discovered that gases like Ozone could quickly break down dye-based ink on unprotected documents. That's why natural-fiber papers are becoming so popular. Crane's, Moab, and Hahnemuehle are just a few that have become known for their quality, long-lasting papers. If you're not overly concerned with how long your printed documents last, you might want to switch to lower cost generic printer ink.

As great as pigment inks can be, they aren't perfect. They cost a lot more than dye inks and are less visually intense than dye inks. Dye based inks last pretty long themselves. For most purposes, 25-30 years is more than enough. Some dye/paper combinations show an archival life of nearly 100 years. That's exactly why dye ink isn't going away any time soon.

Most people who use pigment-based ink for printer use it for its color stability. If you're a photographer and are looking to sell some of your work, you might want to think long and hard about using pigment ink. Don't use pigment inks for all your printing needs, though. Why spend more money if you don't have to? For everyday printing, use dye-based generic ink cartridges.
