I want to print simple business cards and I have my design ready in PDF format which I made with Adobe InDesign, but one printing service is asking me for the original file, along with all the fonts and images I used for my design.
I called a different print service to ask if it was necessary for me to give them them editable files, and they said all that they needed was my PDF file with good print quality.
I understand that if I give them my master file, they can claim ownership of it and use it as their own. Should I give them my editable file? Do they really need it to for print? Why are they asking for it?
