QTR-Quadtone RIP

Like others have said, 120 is too bright. Though I actually think 85 is too dim. I do not edit in a dim environment and just keep my display at 100cdm.

There are two other things to consider as well.

One: What tone is the boarder of your editing app window. Lots of image editors now default to a darker background which can make your image appear lighter than it will actually print. I set my Photoshop background to 98% white so that it more or less mimics the paper boarder and so I can see if any tone in the edges is lighter than 2%.

Two: with really deep Dmaxs or gloss papers, the midtones will always look to dark with linear lab l. I correct for this by mapping the quad values to an modified output curve where 50%K is mapped slightly lighter to 46-47% and the shadows map back to linear starting around 75% through the Dmax (I use my own software for all this).

The glossy prints appearing too dark with linear lab L is basically the opposite problem that matte prints have by appearing too light when mapped to linear lab l.

Hope that helps,
