BTZS: Dr. Elliot Puritz, Steve Nicholls and I have been kicking around issues with paper ES test data. The ANSI density range for a G2 grade paper is .95 to 1.15. My tests with Ilford MG,VC,IV paper placed the EV, in agreement with Ilford's data sheet, at 1.0 or 100. This at the low end of the G2 range. We want to be at the high end of the range to give more "wiggle room" in printing. Setting the paper ES at 1.15-1.2 does that while keeping the G2 grade. |
