Jose Rodriguez has a tutorial video on how to eliminate the 30mm border restriction on fine art papers with the latest version of Qimage, but I have been unable to achieve success. Attached, please find a screen shot of my settings and a photo of the actual result. Prior to printing, I also made sure to right-click the X'd out printer icon and clicked yes in the dialog box. Comments and/or suggestions greatly appreciated.

I have never seen Jose`s tutorial, but I defeated the 30mm trap years ago.
Stay off the paper selections that say 30 in the name.
Use either Other Fine art Paper 2 or Premium Matte N.
See my attached screen snaps
Works fine

A fine art paper must be selected, in order for the Pro 10 to print with MK ink, which is what you want when printing on matte papers. All fine art paper selections invoke the Art Paper Margin 30 requirement. My screen grabs show normal unrestricted borders for the standard Matte Paper selection, and cropped 30mm borders with the Other Fine Art Paper 2. I believe Mike Chaney informed Jose Rodriguez about the work-around in the latest version of Qimage, thus the YouTube video.

Keep in mind that this is a hack that has not been tested on printers other than the Pro-100 (which is why it is currently undocumented).  Your print seems to have defeated the large margin on the left but the print seems to be 1/4 the requested size.  I notice that your PPI is at 1200: shown on your QU screen shot.  You might want to try again with "Prevention of print data loss" set to "On (weak)" in the driver.  Click the properties button to open the driver, click the Page Setup tab, click "Print Options" on the lower right of that tab, and then set the "Prevention of print data loss" on the bottom to "On (weak)".  That should change the PPI listed in QU from 1200 to 600 PPI.  Of course, when you click "OK" on the driver dialog, it'll force you to change the paper size to one of the art margin sizes: go ahead and let it change that and when you get back to the Qimage Ultimate main window, drop down the media size and override it back to 8.5x11.

I'm thinking if the "Print res" value in QU shows 600 instead of 1200, it might solve the problem and print the correct size.  If that doesn't work, it is possible that the hack just won't work on a Pro-10.  You are the first to actually post results from a Pro-10 so thanks for that!  I'm encouraged by the fact that it did print without the large margin even though it reduced the print size by (what looks to be) half in both directions.  If the above suggestion still produces a 1/4 size print, there's one more hack we can try: where we put the page in freehand mode and then double the print size in both directions to see if we can force the proper size: that won't look right in the live view but may print OK.  But we'll see what happens with the first suggestion before trying that.

Regards,
Mike

Thank you very much, Mike, for your detailed reply. Yeah, I noticed the 1200ppi and didn't think much about it. But who knows, it could be what's preventing the image from printing the correct size. I will make the recommended change and see what happens.

BTW, there's a guy on the dpreview printing forum who says the hack works, so that's an indication that something is probably wrong with my setup.

Victory! Changed the default 1200ppi resolution setting to 600ppi and all systems were go. Thank you, Mike!

Does this use Matte black ink ?

Thanks

It should... but I would like someone to confirm that.  Is there any way to read the per-cart ink usage when you print one of these in order to confirm it was the matte black ink that was actually used?  If not, maybe weigh the photo black and matte black carts prior to a print and weigh them again after.  You'll probably waste a bit of ink each time you put the carts back in but as long as the matte black dropped more weight than the photo black (using an accurate digital scale), I guess the test would be valid if anyone feels like wasting a bit of ink to test.  I'd do it if I had the Pro-10 but I only have the Pro-100 and Pro-1000.

I'd be surprised if it didn't use the matte black ink.  When I tested the hack on the Pro-100, you can tell that it was using the driver settings for the premium matte under fine art: because you can tell the difference in print quality when you set it to the non fine art matte photo paper.

I was thinking about making matched prints, one with the standard matte setting, and one with the fine art matte setting, to judge, visually, if there is a difference. Or, perhaps, matched gray scale ramps. I make profiles for the papers I use, and I've noticed a greater black density on the fine art test charts printed with MK ink.

That sounds reasonable.  Or you could just print a normal fine art matte print without needing the hack: just use the art margins like normal.  Then print the same image but with the hack (without the margins).  The two prints should look the same except for the size.  I would think if it's not using matte black for some reason, you'd definitely be able to tell a difference in the black density.

This is an update to the 30mm margin work-around. I ran a controlled test with Canon Pro Premium Matte, with one print using Letter(Art Paper Margin 30), and one using standard Letter with Mike's work-around. Both prints were identical, with no perceivable difference in black density. For comparison, I also ran a test with the same image, using the standard matte paper setting and matte paper profile(resulting in the printer using PK ink). I was surprised at how close it was to the MK ink test prints. The only visible difference was slightly less "meat" in the lowest values. It's a good testament to the quality of the Pro 10 PK pigment ink.

Thanks again for doing the testing on this!  Sounds like you've proven that the proper inks are being used.  That's great news.  It's what I expected though because all the hack does is stop and restart the job.  Stopping the job kills the message about using the wrong paper size and when it starts back up, it just starts where it left off (just past the paper size error message).

Hi again,

I use Moab Entrada rag bright paper with the ICC profile provided by Moab with my Canon pixma pro-10. If I try to use the "Other fine art paper 2" paper choice or the "photo mat pro premium" paper choice I cannot make a print. I get a message asking me to choose a paper format with the fine art magins. On the other hand if I use the plain "photo matte" paper choice I can make a print that overrides the 30 mm border limit.

I printed a black and white image, making four prints.

- one 6 x 8 print with the fine art margins, the "other fine art 1" paper choice and black and white print choice checked in the driver.
- one  8 x 10 print with the "photo matte" paper choice and black and white print choice checked in the driver.
- one 6 x 8 print with the "photo matte" paper choice and black and white print choice checked in the driver, to compensate for an eventual influence of the size of the print on my perception
- one 6 x 8 print with the "photo matte" paper choice and black and white print choice unchecked in the driver

To my eye the differences between the three first prints are very minor. The darkest blacks might be a bit more intense with the "Other fine art paper 1" paper choice but on the other hand I get more details in the dark areas withe the plain photo matte.  I can live with all three prints.

And finally the fourth print seems practically identical to print no. three, with absolutely no color cast.

So, if needed, I can override the 30 mm constraint using the photo matte paper choice. From reading this thread, I was under the impression that this was also possible withe Te "Other fine art 2" paper choice and the "Photo matte pro premium" paper choice. If it is possible, what am I doing wrong ?

You can override the 30mm margin with all of the fine art choices. You need to watch Jose Rodriguez's YouTube video, which was a live stream and aired 12-15-18. The tutorial is towards the end.

Is Mike's hack the same as Jose Rodriguez's hack on his You tube video. I can not replicate this on my Pro-10
