We detected and flattened transparencies in your file
I'm using Indesign CS3 for my book (http://bit.ly/161phxK) and the Content Creator Wizard prompts the following warning (and email)
We detected and flattened transparencies in your file.
That's fine with me. I checked the print-ready PDF and it looks unchanged. There are no problems. But I'd really like to find out where that transparency is located. All my linked files are JPG and I checked the "Effects" pallette to see if the objects had transparency adjusted. Nothing. It doesn't affect the book at all, but it really bugs me. Does anyone have any suggestions?
With best regards,
Eric C. M. Basir
