Oh now that's a whole nutter story . . . back in the day when all we had was a 2/c SORM we got a seven color job in and between the lack of process control and having to re-stack the sheets so many times (shot stack delivery) when we delivered the job it was refused because some were redder some were correct and some were bluer . . . so we went and got the job back . . . went through them and sorted them by hue . . reboxed and delivered the job in two weeks . . . viola job accepted no problems . . . it turned out that when they opened the first shipment you could see blocks of reddish next to blocks of blueish etc. . . . onvce we sorted it out you opened the box and they all looked the same . . . .
