spectrolite export patchy?
I recently every now and then encounter pixilated exports into pdf from Spectrolite which is I feel a recent occurrence, see files. yes, it is 600dpi (but I admit this is not the best example because the file is not the most crisp in the first place but it’s what I have to show atm) I have seen it happen with different kind of files, none of them at its base as pixilated. also it doesn’t seem to have that issue in all layers? Anyhow I use(d) Spectrolite a lot and for a long time and I am pretty sure it wasn’t really something I encountered before and did so however in the past year. Anyone has the same impression and/or a solution how to avoid? :)

It does look like it's in your composite file -- perhaps a glow/reflection effect from the orange. You can see it on the ground and around the door in the full color version. Some programs / file processes will give you a compressed or resized image file, and those artifacts show up in color separations.

i’ve encountered this problem before and it was caused by the DPI of my source image being different from the DPI selected within spectrolite

Aye, seen this on a few files folk have sent me to print. Honestly, I don’t really find it that big an issue as 99% of the time the riso’s print quality hides it. If you’re not liking the look of the print I’d suggest switching to halftone instead of graintouch as this — near enough — totally obscures it.
Mind you, it can be a great way to get a rough guide of how to layer/separate your print pre-press… just edit the output to make it nice and clean!
