Losing transparency when placing or pasting items into InDesign CS5
I know others have asked similar questions, but the answers don't seem to be working for me.
If I have an Illustrator file open and am also working in InDesign, I often copy/paste the vector image into a new layer in InDesign. Today, one of my vector images started showing up with a partially solid background. I can tell that it is behind the vector art, so I went back to the original thinking a fill colour of white must have been set. Not so. In fact, as demonstrated by the two images below, in InDesign there is a white box, and in Illustrator it is transparent (proven by the light blue box I drew behind it). The strangest part is that portions of text outside of the "area" that logo occupies ARE transparent.
I've ticked the "Show Import Options" box in InDesign, but the "Transparency" tick box is not always available.
Some of these logos come from other companies as .eps, so I don't have access to the original .ai files. Regardless of whether they're placed or copy/pasted, the same thing is happening.
Some files aren't giving me an issue while others are. I thought maybe if one document's settings were RGB while the other's were CMYK it might cause a problem, but changing the document settings and saving isn't fixing the issue.
EPS is a flat file format - something is either transparent or it is not - there's no in between. Blurs, shadows, and glows must be expanded and flattened when saved as EPS. In that heart image, the shadow is what is generating the background because it has to be flattened for the EPS format.
You can try re-saving the as .ai then place into InDesign. However, if the original EPS files already contains that background, there's little you can do other than to reconstruct elements or request the original .ai file rather than the flat EPS format.
