Paul W: This is similar to using the QTR Stepwedge Tool Photoshop plugin and the tiffin/kodak q-13 grayscale target. I will have a small section on using alternative means of linearizing profiles, including the scanner and spreadhsheet as well as theQTR stepwedge tool. I think a densitometer/spectro is much much much more useful and accurate, especially when making the six-gray profiles. I just don't know if consumer-level scanners will provide precise enough readings to make the calculations necessary for establishing the five gray_val= settings. I will test it out and will be happy if I am am proved wrong since it will be easier for people to make better profile.
I am finishing up my testing of the 1430 and EB-6 inks this week and will be writing a post about what makes a good profile along with scans of problem prints and measurements. Its too bad that the inks are changing, I hope ther is enough in stock at MIS to last a while before the replacements are available.
