Italian to English Other Printing & Publishing Inkjet technology printing system

Good afternoon everyone!
I'm translating a website for a company that produces inkjet technology printing systems (mobile and fixed flatbeds) and I am having some difficulty in translating terms such as the following:
VALORE SOMMATORIO DENSITA 50% COLORE CMYK (sovrapposizione)

Are we talking of "TOTAL (INK) DENSITY VALUE"? or is there a more specific term?
So, far I have come up with this:

I would appreciate it so much if any of you are aware of any sector-specific IT>EN glossaries...
Thanks in advance
