I like that you can see what your designs will look liketheyre going out in printing, it's easy for me as an amateur designer/marketer who needs quality work quickly while providing my customers high end products at low prices!The only problem is if there are too many errors or problems during uploading of files then sometimes we cannot use them later because they don't get printed correctly (elements do not match). It would greatly help us reduce time spent designing by 30% which saves money when doing business cards but also makes sure every design gets done perfectly before sending off into production.
