Gigi,
It's when I send it to Scal from Inkscape I think, but I will check later whether it's happening if imported directly into Scal.
I think I tried that but the image was too low a resolution to work on in Scal that's why I used Inkscape.
I have managed to isolate the part that disappears and saved it as a PNG, I can import that into Scal, but again it's a very low resolution on screen to draw accurate cutting lines on.
If I save it as an SVG that doesn't work either.
I can import the PNG image into SCAL after I've drawn the cutting lines on the image imported from Inkscape because the image all prints at a decent resolution from SCAL. It's a bit of a fiddle though to fit correctly being a curve and I need to do it eight times
It's a possibility that because I'm importing from a locked PDF that that might be where the problem is.
I can use some software to unlock the PDF to be able to open it in Photoshop and I think it could be the same for Scal not being able to open the locked PDF, but Inkscape and possibly Gimp as well have no problem opening it but I can't get into using Gimp so tend not to bother with it.
I think I imported an unlocked PDF direct into Scal, but again the screen resolution is too low for me to work with.
I'll post the solution I end up using and if the locked PDF will import directly into Scal I'll send it, but if the screen image is a low resolution for puting the cutting lines it won't work for me.
I will get a work around somehow but would like a simpler and less fiddley way of doing it.
