We used an ICC to print the Cone Editions print. The one on the left is a linear print.
Linear printing gives way more control over shadow and highlights detail but it requires one to soft-proof with any of the matte piezo softproof ICCs (installed on your computer already most likely) using “preserve RGB numbers” in Photoshop to see this linear effect on your monitor. It then requires an extra step (an adjustment curve) to bring the image back into good contrast. This extra soft-proof and adjustment step gives you much more control over shadows and highlights but is also more work especially if you initially imaged the photo without softproofing.
This is documented in the manual + there are many posts on this forum as well as at https://inkjetmall.com/blog and elsewhere about linear printing vs icc printing. In general we have always gone the harder route (left print) due to it’s better shadow control but I don’t always recommend this option if you simply need to match a print to your screen without soft-proofing.
Print with these profiles in Relative Colorimetric (with Black Point Compensation) mode to get the effect on the right.
