I use a x-rite 361T to check the UV density of my stepcharts printed on Pictorico with my piezo ink set. Best investment I’ve made but I’m worried I’m getting into paralysis by analysis. Take for example a 60% K patch. On the right side of the Pictorico that patch gets a UV reading of 1.08. On the left side it gets .97. Basically that is true for all the patches. The left side will have less density of the same patch if placed on the right side nearest the print assembly where it rests.
I’m using a 3880.
