Title: Pro-1000 color drop-out
Post by: MikeWhitten on February 02, 2020, 05:16:23 pm

Today I've been working with the new printer, making test prints and setting up paper templates. I've printed a couple canvasses, one 17x34 length and one smallish one about 10x17. Then I made five 17x22 prints on lustre sheet paper. Finally back to the canvasses. I printed two more on 17x34 sheets cut from roll canvass. The first came out fine, the last exhibited an odd color shift near the end of the print. I'll attach an image.

Right after I grabbed a sheet of 13x19 luster and reprinted the same image. No problem.

The printer never reported an issue; nothing sounded odd. Any thoughts welcome.

Thanks,
Mike

PS - there is a mildly dark shadow in the center of the print. That's my shadow; there was a lamp behind me.

The bottom right has reduced cyan, the top right reduced magenta and effects are even which says it's not an ink problem. I'd guess some sort of software issue.

It certainly looked like a digital error of some sort. All the inks have plenty capacity left.

For now I'll just be watching to see if it happens again. I posted wondering if anyone had seem something similar. Google didn't turn up much.

Thanks for the reply.

have you had any head strikes?..  maybe due to the paper not derolled well and curled, is the gap at the widest?

I don't see any signs of head strikes. I'll look again more closely. That canvass doesn't curl much so I want to say no but if this happens again I'll definitely give decurling a try.

Re the gap - the media type is set to the inbuilt "canvas." I'm not at home just now to check what gap that sets.

possible with the length of paper that the vacuum leaked and the paper bulked where the drop outs are??

Hi Bob - since this was right at the end of the print and the line where the dropouts happened is razor sharp I'll say no. Paper bunching I'd think would exhibit some blotchiness; as seen in the image this is a superbly sharp line.

Thanks for the reply!
