Pigment inks aren't perfect—they're typically costlier than dye inks, which they don't have the brightness and broad color vary that dye inks
have. And, most printer makers still push the print longevity of dye inks. Right now, several dye-based prints,
unbroken below glass and removed from direct light-weight, will last for up to twenty five or thirty years, that is over adequate for many of us. however Wilhelm has
tested many paper mixtures that show repository lifetime of nearly one hundred years —that's the first reason
why dye printers aren't going any time before long.
Another downside that some early pigment inks had was a development known as metamerism, that'sbasically
the human eye sleuthing a shift in color once viewing a print below completely totally different light-weight sources. as associate example, a picture may look traditional below fluorescent light-weight,however exhibit a dark-green color forged once viewed outside in bright daylight or below a lamp.
Metamerism infested the primary generation of pigment inks, but Epson, international organization agency
pioneered pigment inks as a thought technology, worked extensively to cut back this, and firms like Canon
and HP square measure reaping the advantages of Epson's initial forays into this market.
