Kodak announced new ink that should last up to 100 years. This is considerably more than regular printer ink which lasts only 15 years. Also great news is that this ink costs less!
In fact, all of your 4x6-inch prints will be a lot cheaper with the new inks averaging 10 cents per print. Meanwhile, letter-size black and whites will run about 3 cents per print. The inks themselves will be priced at $9.99 for a cartridge of black ink and $14.99 for a five-color cartridge. Kodak claims this is 50% cheaper than what you'd spend on say an HP, Epson, or Canon ink refill. So we checked out their prices and in all instances, the Kodak ink saves you a pretty decent amount of cash. Whether the quality is as good—that we'll have to see for ourselves, but analysts have said good things so far.
