I am having a problem with getting the same level of gloss out of a Canon ipf8300 as I do out of my Pixma 9000. Basically the prints come out of the 8300 with the blacks looking a little duller than they do on the Pixma. Both printers are printing the same file, on the same paper (Lexjet Sunset Metallic). I have attached a couple pictures to give an example of what I am seeing. The glossier ones are from the Pixma 9000 and the slightly less glossy ones from the ipf8300.
Looking at the ink usage report, it shows mostly photo black, but with a small amount of matte black. (.015ml matte black vs .042ml photo black and also .083ml grey vs .034ml photo grey) I suspect that this might be what is causing my problem since the Pixma doesn't have a matte black ink. I am not sure, however, how to get the printer to not use the matte, or if that's even possible
I have tried lots of different paper settings (including the custom profiles from Lexjet's website) and none of them seem to make a difference. I made sure to double check that the paper settings I was using specified Photo Black in the profile and not matte.
The printer is using the latest firmware. I have tried printing from both the standard Photoshop print dialog, and the normal export plugin. Neither seem to make a difference. I have tried different rendering intents (perceptual, relative colorimetric etc) which also didn't seem to make any difference in the gloss level. I even cut some of the roll paper and fed it into the Pixma just to rule out the chance that the same brand of paper was somehow different in roll format.
Is there any way to get the glossier prints from the 8300 or is this just how it prints? It seems like it should be able to do at least what the Pixma does.
I would appreciate any ideas anyone has of things to try, or even wild guesses at this point.
