So I'm trying to get into inkjet printing (until now I've sent my files out to a lab for printing) and had a somewhat disheartening discussion with a printing expert at Foto Care on 22nd Street in NYC. I was picking his brain with an eye toward choosing and purchasing a printer, and he asked me what kind of monitor I'd be using to prepare my prints. When I told him that I used a 21.5" iMac, he shook his head and told me that I'd never get satisfactory prints out of it due to the monitor's gamma being optimized for video. He said the monitor would never correctly display my highlights, and suggested I should just continue sending my files to the lab. So my question is, does anybody with more inkjet experience than me have any tips on using an iMac monitor to process files in preparation for inkjet printing?
