The Hewlett Packard C6658AN (C6658A) / HP 58 Photo OEM inkjet cartridge, in conjunction with the HP 57 tri-color and the HP 56 black inkjet print cartridges provides six-ink, virtually grain-free photos that have exceptional fade resistence for generations - a significant improvement in the light-fastness of dye-based inkjet photos. HP C6658AN / C6658A and printers are designed to work together for crisp, sharp output everytime. This photo ink cartridge contains 1/3 black, 1/3 light cyan and a 1/3 light magenta. You replace your black cartridge with this photo color inkjet cartridge. It goes in the black slot, not the color slot. When you have the photo and regular color cartridge in your printer it produces better looking photos. Instead of only having four colors to print with (black, cyan, magenta, and yellow) it now has six colors. Photo inkjet cartridges are great for people who print lots of photos or color documents but not recommended for people who print mainly text. This is because the photo cartridge has about a third as much black ink in it compared with a black cartridge. Once this ink is out the cartridge has to be replaced. Even if the light cyan and light magenta sections are full of ink you will need a new cartridge. Printers these days print photos well with four colors but excellent with six colors. -Print photos that last twice as long as most traditional processed photos -HP Photoret IV in six-ink color printing
Specifications
Page Yield (?)
Page Yield is an approximation of the number of standard pages that can be printed with one cartridge, usually measured at 5% page coverage. 5% coverage is a standard 8.5 x 11 inch page with a light letterhead, address and three paragraphs of text double spaced. If you print mixed text and graphics or WebPages your page coverage is closer to 15% and therefore the number of pages printed with each cartridge will be less. If you are printing photos your page coverage is close to 100% and the number of printed photos will be much less than the amount the number of pages you would be able to print if you were just printing standard text documents.
