How's your spot color accuracy?

[virtu]

Hello,

I am just curious how accurate can you print spotcolors?

My best result:
4C UV-printer 138 inch : about 50%
12C - iPF9100: media manager says 95%

Depends on what delta tolerance I look at. I've got 48% at less than a DeltaE 2, but 94% at less than a DeltaE 10. My average DeltaE is 3.31. How that relates to the real world, I don't know. All I can tell you is that I never match dark blues or dark purples - they usually go quite gray due to my GCR levels... but my paper gets way oversaturated otherwise.

Hello,

Ok, i took a deeper look into it. I got 60,04% less then DeltE2, less then delteE5 77.7% and deltaE<10 96.55% with my 4C UV-printer.

The 2nd Tool Colorscale (if i translated it correctly) shows everywhere 0%. Can someone please explain what that means?
