I recently designed the layout on an album cover. Upon sending the files for print, they said that they have a problem "separating the template from the artwork" (the label provided a template to use for the layout) and thus requested a "layered PDF". I was wondering what is it? I already had sent them both a PSD file and a PDF file.
I did notice that in the save as window there is a checkbox for "Layered" upon choosing PDF, but it's checked by default, so all PDFs should be "layered" automatically by default? Assuming that's what they meant.
