Replying to my own post, it helps to convert your 21 step file to GG2.2 for piezography. I was printing untagged which was causing the odd results. Dumb

You can measure the 51 step target and then graph a chart in Excel or or Numbers or google sheets, and observe if the shadows block up at the end of the scale.

You can make custom targets with the RGB values in ColorPort and then convert it to greyscale afterward and then print through QTR. You can paste this below
