"He who marches out of step hears another drum." ~ Ken Kesey
AccuRIP has a test film that you print out; then, each block (5% increments) needs to be read with a densitometer, to see what it really is (10% might actually be 8% or 13%, and so on). When you get the readings back, put the corresponding readings into the boxes; AccuRIP will compensate using those readings; let's say your 30% block came out 27%, AR will bring it up to 30% as it should be, and so on for each tone...Steve
Good to know if I ever have to upgrade...Steve
