What’s "pre-flighting"? I’ve not heard the term before
Come to think of it I never heard the term either until I took a class at Calypso 🙂 Anyway, it’s just jargon meaning to do all the digital prep work ahead of time so they can dump the file into the printer without doing any other work on it (except to gang it with other such files).
Specifically, for their LightJet you’d do all the color corrections and soft-proof using one of their ICC profiles you downloaded earlier, resize to 304.8 ppi at the size you wish to print at (LightJet is res 12), sharpen, convert-to-profile using their profile, add a white canvas border (if desired) and add a black line to the edge for cutting (inside stroke 4 pixels wide). Then you send them an uncompressed 8 bit tiff and they don’t have to do anything else with it except print and cut. For doing all this you get a lower price.
