I have just started with a company who make a 72pp catalogue of products. There are hundreds of linked eps files used for the product photographs (electrical trade products so typically white and awkwardly-shaped). The catalogue is put together in InDesign CC and sent to the printer's as a pdf.
As I understand it, eps files are used because they offer transparency, which is necessary when dealing with many images layered over blocks of colour etc. on the page, and I obviously don't want to (re)make clipping paths for thousands of images.
My first instinct is to try to move away from eps to pdf, for the sake of file size if nothing else, there are linked eps images ranging from 92kb to 185mb(!) in size for pictures never larger than just under A4 and generally only about 20mm wide.
I've googled around for a clear answer but anything about eps focuses on vector graphics, and there's no obvious finished image file answer for photos with a transparent background.
Am I right about moving to pdfs for such small images and if so, is it worth converting nearly 10k images?
