Hi - hoping someone can help.
I sent the attached PDF - http://www.sensecreative.co.uk/custUploads/SENSE-36-7977-95928/77317/S ENSE-36-7977-95928-77317-2440.zip - to print with Sense Creative. The cards were printed and they've turned out quite visibly green on the reverse (where it should be white).
I've printed the artwork on several printers I have access to and it looks as it should, however SC are saying that the issue is with the artwork
"The green tinge you see on the reverse of these cards is prevalent in the artwork. The makeup of the background is approximately c-15 m-11 y-15 k-0. the predominant levels of the yellow and cyan will give you the green tint. Upping the levels of the artwork in or substituting the cyan, magenta and yellow levels with more black in Photoshop will likely give you the result you require. We are satisfied that in both instances, the artwork has printed correctly and the colours are well within tolerance given the nature of the artwork."
So, I'm in a bit of a pickle as the cards are needed for an event next week.
How do I change the image levels? Or are they talking nonsense and trying to pass the buck?
Help!
