RE: How large without a preshrink?



I have "problems" with even 8x10" image size. BTW, the amnt. I find to be a problem to me is "something over 0.7mm for 8x10" image size". (Roughly 1/32".) It's a strict criterion; probably the same amnt. isn't considered as a problem by others... What I experience is somehow compatible with Christina's figure. (Twice the paper size, twice the registration error...)

Hi Paul,
I find that anything over 8x10 is problematic.  My gum prints are usually on 15x22 paper (half a sheet) and even with shrinking, the long side with multi layers will be off 1/16".  This is not only due to shrinking though with repeated washing, but due to the thicker gum which sucks up the paper a bit. You can see this on the back of the print--the areas with heavy layers are sort of indented and in reverse relief, if I can describe it that way.  Even with ironing the print between coats, which I do on my kitchen counter (the only ironing I ever do--I don't have a dry mount press at home) that relief is still there.

I have no problem, though, sizing unshrunk paper and then shrinking afterwards if, say, I have extra size and no more shrunk paper to coat.

I have heard of those who do not shrink at all with Fabriano Artistico but that doesn't work for me very well...
Chris

Hi all...

I was wondering among all your collective experience: How large can a multilayer gum print be made without a preshrink and without registration problems?
