Hello guys,
I finally decided to replace my old and beloved Canon Pixma PRO-1 with the brand new Canon PRO-300.
One of the reasons why I upgraded was the PRO-1 restrictions on margins because I couldn't print borderless (or let's say, with custom borders) using matte black.
I must confess that I really like the PRO-300 as everything seems to be much easier, starting from AM1X profiles to connectivity.
However, after a couple of prints on cotton paper (Hahnemuhle Photo Rag Ultra Smooth), I start to have doubts about the usage of MBK ink as the level never goes down unlike the photographic black

I try to summarize my questions here hoping that somebody already found an answer:
1) If I use a proper AM1X (proper means downloaded from paper manufacturer website) for cotton matte paper, should I expect that MBK ink is "activated" right?
2) Is there a way to "inspect" AM1X profile in order to check if everything is set properly?
3) Is there a specific way to print borderless (with MBK ink)? I ask this because even if I prepare an image correctly in terms of size (so let's just say that the image is smaller than the paper), if on Canon Professional Print & Layout (I suppose the new Print Studio Pro plugin) I check the "Borderless printing" box I get a magnification effect on the image. It's like PP&L is trying to fit the paper with the image instead of just letting me use the native image size (actually the magnification goes even wider than the paper). If I don't check the "Borderless printing" box, the image has a defined size whatever is the real image size. For the test, on PP&L I selected as "Apper Size" just A4, so not the A4 Margin 25 option.
Thank you!
