Hello, I'm in the process of creating somewhere around 50 layouts in Photoshop. I was planning on sending these layouts to be printed. I was instructed that "Ideally" they would receive the layouts as one or two .pdf files so that they wouldn't have to deal with each layout individually. My question is: Will there be any quality drop off when saving as a .pdf? Are there some things that I should watch out for when doing so? Also, can I continue to add to a .pdf without having the full version of Adobe Acrobat? Thanks
