Function
Non-photo blue is a particular shade of blue that can not be detected by graphic arts cameras. This allows layout editors to write notes to the printer on the print flat (the image that is to be photographed and sent to print) which will not show in the final form. As well as this, it allows artists to lay down sketch lines without the need to erase after inking.

Famous quotes containing the word function:

Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
“Literature does not exist in a vacuum. Writers as such have a definite social function exactly proportional to their ability as writers. This is their main use.”
