My print has got a plain dark grey background CMYK of 0, 0, 0, 90. This has just been rejected from the printers because 'it was black space and not CMYK'.. Not fully understanding this I decided to combine small amount of the other inks perhaps CMKY 30, 22, 22, 80 to create the dark grey. My problem now is that I have a lot of small white text over the grey so I'm worried that using a mixture of inks will make the text be blurred at the edges where the ink doesn't quite line up.
So I have a few questions really.
- Does anyone know why this was rejected at the printers - could I have saved it incorrectly from inDesign, or can I just not use the combo 0,0,0,80?
- Can anyone recommend a good CMYK for dark grey?
- Any tips for not ending up with blurred white text?
