Re: green-yellow
That one below was a very nice explanation Alberto thanks! On the other hand your "plausible" explanation to my original "why green? (whereas I always find it to be yellow)" question contradicts to my knowledge on how printer works; printer has ink limits and to my knowledge the printer will never put more ink on a spot (area if you like) when printing with more than one inks. The limit is set and constant, whether you use a single ink or a combination of inks... This is the background of my question -> I'm not into colors and such but trying to figure out what is happening ink-wise and why others report contradictory (to mines) findings whereas my findings are consistent with 3 different printers using 3 different inksets. Maybe there's a chemical reaction when inks merge increasing the number of double bonds available per given area - who knows? Anyway, we can continue or not -> I'm indifferent. The primary purpose is to (being able to) make prints, the rest is mere rhetoric... (But can be also enriching sometimes!)
