Re: Epson R2400 inks density - DISCLAIMER



- the absorption of a colour reduced by 50% (e.g. for Y: 255, 128, 255) is as low as about 15-20%. This is really puzzling to me, and I have no explanation.
Mark,
While the values in RGB are Linear, the actual densities are not.
I know, but 15-20% is less than what is espected converting transmittance in absorbance (50% T = 0.3 A).
