While creating new profiles for my printers, I noticed that the Canon PRO-4100 is considerably more grainy than the PRO-1000. This grain is especially apparent in the yellows, but it exists across all colors. For months I thought this was just a limitation of the hardware, but now that I'm comparing the two printers side-by-side, it seems like the PRO-4100 may have an issue. The sample images I'm including here were produced using the same source image, software (Photoshop), paper (Hahnemuhle Hemp), and profile.
Has anyone else noticed grainy/noisy prints from the PRO-4100? I've tried a head cleaning, using different ICC profiles, and using different papers. I haven't done a system cleaning yet, but I wanted to check these forums before wasting anymore liquid gold than I already have trying to debug this issue.
In these images below, check out the color bands, especially the yellows...
