Canon CLI-251XL BK & PGI-250XL PGBK Compatible Ink Cartridges - High Yield Replacement for Canon Pixma Printers - Perfect for Home Office Printing & School Projects

Gosh, these things are expensive. As I said in another review, I hate every time I am required to order a new one. But for printing high-quality photos on Canon paper, these Canon inks can't be beaten. Color accuracy, operation, and the all-important "end result" makes these the item of choice whenever printing a high-quality image, and the "BK" color is as important as the primary ink colors. I use mine on a Canon Pixma iX6820, a printer that uses two black cartridges, including this one, and when I print in high-quality mode on Canon's best glossy or matte 13 x 19" (A3+) papers, it still shocks me at just how good the results are. All inkjet prints will fade over time, particularly if you have the print in an area where sun or humidity are at play, but these genuine Canon inks will stand up over time more than off-brands.Note—and this is very important—that this is the "XL" version of the cartridge. It is the same physical size as the CLI-251 BK, but contains a higher quantity of ink than the standard cartridge. I try to purchase the "XL" versions whenever I can because of some increased (minor) economy, and the fact that the cartridge does not have to be exchanged quite so frequently.So, how do I handle the cost? I use third-party inks when printing handouts on plain paper for the office, but when printing photos, I stay with these Canon inks. In spite of the price, their superb, consistent performance make them a Five-Star item.
