I've creating a a4 advert for a magazine in InDesign CS6, I need to bring in a logo from Photoshop. The logo I'm using was originally transparent but was made up of a number of colours. I removed all of the colour so the logo was completely white but keeping the transparent background.
I've saved this .psd file and then placed it into my InDesign document. All looks fine onscreen, but when I come to print the transparent area of the logo is being picked up on the blue background, causing an overprint effect, so it shows up as a slighlty darker blue box shape.
I'm not sure if the issue is with the PSD file I'm reading in or our printer or what?
We have tried importing the artwork as a transparent .PNG, .TIF and .EPS file and it is still not changed.
