Sandy ,

I do use quadtone rip to print negatives with Jon Con’s method 3 curve. But I’m not sure I understand, (there's no surprise there) why I couldn't print the HSL color Array on Pictorico, using the Quadtone rip driver with Jon Cone’s QTR Curve for OHP

(NewS9aNG2b-PictoricoUPohp.quad.)

Then print that to determine which color provides the best UV blocking…Picking up from there I would as previously described,

> Create a step wedge with the chosen grey/color blend, and determine the new Dmax exposure time for the tissue with this new color.

>

> Create Chart Thob step tablet filled with the color chosen and print it.

> Scan the print into photoshop and analyze with Chart Throb. Save the Chart Throb Curve.

>

> Create another CT step tablet (or use an image) with the new curve applied to a positive. Apply the color picked to the tablet and print.
