I have been trying to do this for the past few weeks. I must have printed over 60 step wedges using various techniques.
My Development time is based on the print out of the Stouffler 21 step wedge which renders the first step pure black. I continually re-check this with each paper that I coat.
Using the text file that you kindly gave me I have printed your original and then which gave me many pure white steps, and hence reduced the ink levels 5%, 10%, 15%, 20%. The best result I got with the reduction of 5%, but even that produced only a print with a 95% reading of the pure black.
I think I must have a problem with my technique..
I have been using an epson 850 to scan the prints and measure their values in PS. I cover the a small area on the 0% area on the negative, with a small tape (used like rubilith which I dont have) and use this to set the white point in PS. It is always paper white.
I then use blur on the printout and contimue to measure the values of the print using the eye dropper.
I also have a colormunki which I could use (if you think it is a better way of doing things) to get LAB values but I dont know how to use these values after.
