I learned this 15 years ago. Now it bites me in the ass.
Somehow the computer went to default on Energy setting. So it was going to sleep before the print was done.
Fixed
If too much ink is laid down it will take longer to dry or not dry at all. Black ink on baryta Gloss is an example. I use a wet polymer coating on canvas and heavy areas will bleed if not enough drying time is given.
BTW This is with an ipf8300 OEM Inks and 3rd party papers
Yes I stated that billboards are low dpi.
Giclee Fine Art Reproduction needs 300 dpi.
A friend that prints landscape also uses 300 dpi.
Both my artists and myself see the difference.
I have printed that size many times. Since I mostly work with artists reproducing their work, I always print 300 dpi files.
The questions you need to ask are what is the ink set. Are you okay with Aquous where the print will need to be coated, or would you rather use a latex or solvent based...
Over the decades I made many hand coloured B&W portraits and landscapes. These usually started with sepia, selenium or gold toning silver bromide or silver chloride papers. Several techniques and materials are still available to photographers. I suppose I migrated to an alcohol-water based...
Not in this case. The image started in a medium format B&W film camera. A traditional wet darkroom print was made on Silver bromide dodging and burning under an enlarger. Then the image was hand coloured with water-based dyes. Next I copied the image onto 4x5 Ektachrome film.
After digitizing...
Some printers allow you to print multiple times on a sheet but others do not. My older now decommissioned 9600 would allow but my ipf8300 does not, or at least I have never been able to. I think a sensor sees that the paper is not fresh and won't load. Try experimenting with your Canon. Try...
This forum doesn't allow large images. My post #3 shows an infrared false colour pano. Here is a detail out of a building in the right quarter. It shows people going up the stairs that I did not know were there. BTW the image is not stitched. The scan at 50% res took 63 seconds.
I bought the same circuit cables, but, when I got into the ColorMunki the cable was still good and, the plastic that held the reflectors was also okay. It turned out that the reflectors weren't reflecting because they were fading. See post #26. I decided to fix only the reflectors and all...
Another image;
Interesting story. I was weed whacking and I caught a stone. It took fight and then took out the glass pane on the next door neighbours deck. As the sun started to set I seized the opportunity to place my pano rig in that very opening which was accidentally created. Then five...
