Epson R1800 Red and Blue...

Is there anyone in this forum who can measure and post the nominal solid ink density Lab values for the Epson Red and Blue inks?


Regarding the Epson UltraChrome Red and Blue…

I’ve discovered that the Blue ink is not blue at all; it is is Violet.

Can anyone in this forum help me understand how Violet can also be Blue?

I have always considered Violet and Blue to be distinctly two different hues.


I can’t explain why they would call violet blue…maybe defined by its position in the spectrum…or simply marketing, but I have seen some hi-fi color systems expanding on hexachrome by adding a violet ink. And obviously the addition of this ink is to give the gamut a boost.
