If possible, please supply your artwork in CMYK with a FOGRA39 colour profile.
If that makes no sense to you whatsoever, don't worry about it. Our talented Studio team will work their magic and let you know if they spot any problems with your artwork.
If you require further assistance, our Customer Experience team is standing by to help between 9am and 7pm, Monday to Friday. You can reach us on 0345 222 0345 or email@example.com.
