Good idea ... in theory. When you load a roll into your 7900 and print at 360ppi and don't get the results you expect, you may want to do the test I outlined and look at the variables. Hint: the driver handles sheets and rolls differently.
2 + 2 never makes 4 in photography, and the nominal sizes can be very different to "real world", but I would have thought that 360 * 24 = 8640?
... and the sensor is 8956, so you would only lose a few hundred pixels?
Does the 7900 not print edge to edge on roll paper?
If it does not print edge to edge, hopefully the edge would be covered by the frame if I did not mount.
I will be using the ColorBurst RIP, Does that make any difference?
I have not put ink in my 7900 yet, as I would not have used it much, and I understand that they tend to clog if they are not used regularly.
