Hi - I'm a graphic designer and print broker. I'm doing postcards for a client, and found a good deal so I'm paying to have them printed then marking them up somewhat. The printer wants me to sign off on the job, as well as my client. I couldnt understand why they want my client to sign off as well. Being a broker I would like this to be transparent...am I asking too much by asking them to only require my signature? Thank you for any comments! - Greg
