On behalf of Bernard-Amsterdam who has a problem with big files recently. Information gathered by phone. Windows 10 recently updated, his guess as being the cause. Qimage Ultimate several versions including the last. Latest Canon iPF8400 and 4000 drivers. Printing four long leporellos on 44" wide paper, 24 cm wide 9 meter  long, 10" 30'. Scan line out of range error. The same when just one is printed on a small roll width, 800 MB image size, 8 bits file.

Met vriendelijke groet, Ernst

I just tried a 10 inch by 360 inch print on the Z3200 PCL3 and it printed without issue.  Can you give me the specs on the 800MB image: what is the resolution of that image?

Edit: also, the length limit on a Canon Pro 4000 is 125 inches.  How is he getting 360 inches?

Regards,
Mike

Mike,

I will ask for the file. The max print length of the Canon ImageProGraf Pro-4000 is 18 meters, 60' .  https://www.usa.canon.com/internet/portal/us/home/products/details/professional-large-format-printers/professional-photo-fine-art/imageprograf-pro-4000

The file would be good to have but in absence of the actual file, just knowing the exact resolution of the 800MB image and the exact print size chosen would help.

Attached is what I get when I try to create a custom size on the Pro 4000: max is 125.98 inches.  I did discover that if you click "Size Options" instead and SAVE a size, you can go to ~700 inches so there appears to be a way to do it.  Why they limit you on the custom size method, I don't know.

I may have discovered the problem.  In order to get an 800MB image in the 10 inch x 360 inch range, I have to go higher than 65,536 pixels on the long edge.  QU is currently (always has been) limited to 65,536 pixels in either direction and that may be the problem.  It should give you an "Image Read Error" instead of the mentioned error message but it shouldn't matter in the future.  The QU 20th Anniversary Edition releasing later this summer will have the capability to do twice that pixel size.

Mike, the odd thing is that Bernard etc finally decided to bundle 3 of the files in one image, total 2.5 GB, 8 bit, 280 PPI, >72x960 cm print area, and print from Photoshop on the iPF Pro 4000, with your size creation of the 4000 driver in mind. He phoned me at 75% of the length printed, fingers crossed, and the print was ready some hours ago. Now he has to fold the leporellos and cut them while folded .........

I guess further back in time they never hit that length in pixels (lower resolution files), though they reduced the resolution for the trials this time to get this job done and it failed with QU. Might still be another cause given the error text.

My jobs did not go beyond 5 meter if I recall it correctly. I used Qimage's print to file then to first set multiple images after another for a 5m long leporello image. Three of the files then on the print page, some white extra for tolerance at both ends,  1mm white +border and dashed lines along the length for cutting by hand later on. Folded after cutting, cut the extra white at the ends then. Worked well. Not my favorite jobs.

Met vriendelijke groet, Ernst

If printing leporellos, I think I'd just take the one massive file and cut it about halfway (at one of the folds) and just have a left and right half.  Then print the left half at the top and the right half on the bottom, butted against the top: similar to compact placement mode. 

In fact, if you are starting with one image per page in the leporello, there's no need to create one huge file.  Qimage can print each of those pages side by side (or top to bottom) using compact placement mode or by creating a layout.  Then just select all of the (I'm assuming probably 30-40) individual page images and let Qimage lay them out.

Thank you Mike for the advice so far,

Done all the possibilities. I like to have a continuing dash line along the length of the print (not between pages) and an easy nesting of 3 or 4 leporellos in the width of the roll of paper. So far it worked for me. Breaking up a leporello because it is more efficient on the roll paper when a single one has to be printed is harder to sell to a customer but price does wonders then.

Met vriendelijke groet, Ernst

Interesting to hear all the ways people print and the various needs for different kinds of jobs.  You could get close to that (a solid instead of dashed line) by using a thin photo mat on the prints.  For example, use a .1mm top and bottom mat on each print to give you a solid line at the top and bottom... or do it on the left/right if you are printing on a portrait page and the leporellos goes top to bottom.  I assume that line is for the purpose of cutting so it shouldn't really matter if it is dashed or if it has a small gap between pages.

Mike, never thought about that method, dashed or solid does not matter. I could use a bit more instruction on that method. Edit; more in the sense that I used that feature and abandoned it as it does things I would not expect when I change the images sizes on the print preview. Tried it again and it is the same. I doubt I would use that for the task discussed in the thread.

More often I had a need for just two lines to indicate where to cut and leaving the other opposite sides unmarked, the cut marks etc do not have that choice I think. For example when on a sheet or roll an image + border just fits when the print margin is added (5 or 12mm) so I do not use any cut marks etc in settings then and measure manually for the cut. The other example as a fast way to get an uneven border. I know you added a feature for the last, photo mattes. I would not object to a choice like that in the cut mark etc section. As a matter of fact I would not mind another feature; the possibility to have cut marks On or Off per image on the print page, had a job this week that could use that.

In the end, all roads lead to Rome.

Met vriendelijke groet, Ernst
