Hi,
I am not sure that this point was discussed before or not. Which device should be better to the newspaper pressroom: densitomter or spectrophotometer? At present we are scanning gray bar (not black) on the color pages and try to keep the C, M and Y density values within given specification on the presses. We use status T (absolute) on densitometer. It happens that due to different shades of paper: same density may have different L, a and b values. Also spectrophotometer may be useful to check the Delta E between proofs and printed copies and also 'b' value of the paper. It would be great to have some information on which device we should apply and why?
Thanks.
