Review on COLORETTO Printer Ink Cartridge Replacement for Canon PG-240XXL, 240 XL & 240 XXL (2 Black) - Compatible with Pixma & MG Series Printers - Combo Pack by Nick Walker

At first I really thought I would like this ink but I've noticed that if the print rubs against something for at least 2 minutes after printing it will smudge. One of my main uses is to print shipping labels (on plain paper), so I tend to stick them on the boxes soon after printing so I don't mix up the orders. I had to reprint some of the labels because they are so smeared I'm afraid the post office won't be able to read them. I should note that the problem may be made worse by the paper I'm using, and maybe less so by other paper. However, I have never noticed this problem with other cartridges.
