[Ink stained Fingers]

There is a black dye, but the driver mixes dark grays down to about 95% darkness with CM, and then phases over to black, and RGB=0 as black is printed with the black ink, but sometimes depending on the printer settings the driver is even adding then some C or M to tune and neutralize a cast in the black dye. This is very prominent with the text black, set the driver to normal paper, gray scale option on and print a black spot, that comes out as a dark brownish gray, now remove the gray scale option and print again - the black is getting darker, with the help of a C byprint. Similar things can happen with other paper/driver settings. That's happening in the driver and beyond your control.

Here are the results of one more week of my fading test. Here is IS inks for PGI-x20/CLI-x21. Notice that only Cyan seems to have faded noticably and not much more than after one week. It looks like the ink set could be improved very much with a better cyan. Click to enlarge:



Here is test of the cheap compatible cartridges. It can be seen that they are now also starting to fade, but to a lesser extent, and it seems cyan fades most. The B/W images and the greyscales are shifted slightly towards red/magenta, meaning that the fading is mostly cyan. Click to enlarge:
