Halp!

I clearly don't understand how digital images work.

I've been merrily working on Lashings poster images in the GIMP - all finished and ready to go, but oops, they need to be in CMYK colour format. Only GIMP doesn't support CMYK colour. Oh well.. I think my work computer has PaintShop Pro on it.

So I bring the images to work, open them, and re-save them in CMYK...

And now the purples have gone red, and the emerald greens have faded to mint, and I don't know wtf is going on. Surely computers transfer colours seamlessly from RGB to CMYK every time you hit "print"... so why can't PaintShop Pro do it?!

Can anyone advise?

Luckily, these printers want me to submit my images as PDFs. But I have learnt a valuable lesson for next time...
