Do I have to read the patches from black-to-white or the other way around?
Printed the 21 step scale, read it with Spyderprint and exported it to a text file. Made 8 sets of measurements from light to dark.
Any text file dropped on "QTR-Linearize data" give me the same answer : 'The Lab values are not in order.
Cannot be linearized."
Don,t know if I like the way it goes…

Hi againsmall question: do I need to relinearize if I'm just changing the tray shadow value?I did increase it and I dropped the whole profile on to the QTR_Linearize date, then I changed the values in the linearize line. After that I made the quad file.Is it the way to do it?Thanks again
You don't want to mess with the ink limits, because that will throw off the gray values (cross over points) settings for each of the lighter dilutions and can cause banding in smooth gradients or even bad tonal reversals.To give the shadows more separation you can try increasing the GRAY_SHADOW=" " default is something like 4-8 but I've been using a shadow setting of 15-18 for this inkset)You can also try increasing the GRAY_GAMMA=" " start with an increase to 1.2 to see if that helps,You will need to then relinearize the profile.Richard BoutwellJacques Caron
