Re: maintaining meta data in eps files
Are all of your computers running the same software versions and operating systems? Are you finding images (processed on other computers) that do not have the metadata you want or have you watched this happen on your computer? Have you opened a jpeg with metadata, saved it as an EPS then not have been able to read any metadata? In other words, look for variables among the files.
It could just be that someone is opening the file in Photoshop and then copying the contents into a new document because they are afraid of messing up the original. That would definitely trash the metadata.
