Image has background when i print but not on the screen
I have put a psd images in my illustrator document, when I made them in Photoshop I made the background transparent and the images look like they have no background on the screen but when I print it out you can see it has a slight shadow around the image which dulls the colour behind were I have put the image. Any advise appreciated.
If you used a layer mask, make sure your black color recipe is 100% in all CMYK (Cyan 100, Magenta 100, Yellow 100 and Black 100).
If you use the default black to do your masking, it's possible there will be a bit of transparency on your mask and show the background. It's often hard to see so maybe that's why your background looks perfectly transparent in Photoshop!
