By the way, a 60-70% tint of each colour in a band all the way across the sheet (perpendicular to the sheet's direction of travel in the press) is another useful trick - an uneven screen is another immediately visible sign that duct settings were uneven. (I wouldn't be surprised if a profiling chart "tracked" through a screen to some extent, though, since the total ink coverage over the length of the sheet can change abruptly from column to column.)
Sounds like excellent advice. A CMY grey bar right across the page too (at the recommended percentage for grey for their press setup) is also probably a good thing. Graeme Gill.
