I use LR and PS CC on a Windows 7 machine, working on images on a Wacom Cintiq 12wx, and printing to an Epson R3000. I am calibrating the Cintiq with a Spyder4Pro (but the controls on this legacy Cintiq don't make adjustments easy).
This arrangement has worked well for me for years and is still working well: my prints are neither too dark nor too bright; the tonal range of the prints looks A-OK to me; and, at first blush, the print and the image on the Cintiq look close--close enough that I am not prompted to look more closely to see just what, if any problem, might be present.
Then, along came Mark's post about the Aardenburg monitor checker. Well, why not, I thought. So I downloaded it and checked the Cintiq. Here's what I found:
1. Gamma squares: of the six, the first and last squares are blended; the other four show distinct halves, that I would judge to be close but no cigar. If I add a curves adjustment layer and adjust the L-layer, those halves are easily made to blend.
2 & 3. Blackpoint & Whitepoint clipping: I'd say these are both OK. I need "to find" the X; the Z is more easily found.
4. Lateral adaptation: the horizontal L=50 band does not show any ripling.
5. Color checker: I don't have a color checker.
My question is: where in my set up do I make what adjustment to attempt to make the inner four gamma squares blend?
Using the Cintiq's "controller," I can adjust brightness, contrast and backlight of the display. Is it the contrast setting that I need to adjust to achive a better blend of the gamma squares?
I have color (within the display GUI) wherein I have the display set for 6500K. I notice there, that RGB values are set at 252, 236, and 250 respectively. I assume that the Cintiq software has set those values; let me put it this way, I have no recollection adjusting the RGB values to those.
So, back to my question: How do I go about trying to make a better blend in four of the gamma squares.
TIA for any comment, advice, instruction.
