Ok understood that you printed GLOP bigger than the image.
But if you look carefully at the IGFS margins beyond the GLOP you'll see
that they are a bit blotchy with what I presume is GLOP splash or from Glop
on your rollers. Angled into the light it looks like a slight mould attack
might look. Its not obvious or irritating, but that's what I was referring
to. My guess is its GLOP off the rollers.
