Hi,

I am experience a change in colour when uploading my artwork. All my artwork was created in CMYK space in illustator, saved as pdf, and then uploaded. When I look at the proofs, the colours are noticeably altered - am I doing anything wrong?

Here is what I see in illustrator:

Here is what I see on the proof window:

Any ideas?

Many thanks!

Hi Glen

I can see why that would be worrying.

However I can assure you that is not something to worry about. The proof images created are RGB jpegs (as CMYK jpegs are not widely supported).
When it comes to printing, we print your original files in CMYK so they should come out as you intend them (or as close as realistically possible).

I hope this puts your mind at rest.

Great ok thanks!
