I have been trying to Linearize some Hahnemuhle Museum Etching and ran into a problem with the warm curve. I am using a 9900 and have mapped my LM to OR in the quad file and the spreadsheet. I make the initial 256 chart and all is good. I plug in the original warm quad and the measurements into the spreadsheet and copy the new curve. When I print the 256 chart with the new curve, it doesn’t look good at all. The middle is almost the lightest color. I opened the linearized quad file and there is nothing there for the OR which is my Warm Medium ink. I look at the original curve and there are numbers in the OR.
I then made a real simple 21 step chart and measured by hand. The same thing. I then tried to linearize it with another software and printed a 256 step chart and it came out right.
What am I missing? I attached an image of the bad chart. Don’t mind the stains, I pulled it out of the trash.http://gregbrophyphotography.com/warmchart.zip
