Digital BW, The Print

Ukko,

I was also surprised by these comments. I posted some i1/Measuretool 
readings of a 21pt grayscale printed on the R2400 with the default 
Neutral/Darker setting - on Premium Glossy. Here they are again.


1      94.21    -0.20    -3.60
2      89.45    -0.02    -3.20
3      84.62    -0.01    -2.88
4      80.46    -0.03    -2.68
5      75.57    -0.07    -2.89
6      70.99    -0.35    -2.68
7      66.51    -0.10    -2.14
8      61.72    -0.30    -2.01
9      57.06    -0.53    -1.93
10    52.32    -0.44    -1.95
11    48.09    -0.49    -1.63
12    43.16    -0.58    -1.62
13    37.83    -0.36    -1.14
14    32.26    -0.40    -0.94
15    27.61    -0.41    -0.65
16    22.82    -0.27    -0.43
17    17.83    -0.18    -0.39
18    13.03     0.03    -0.35
19      8.57     0.21    -0.03
20      5.52     0.04     0.18
21      2.93    -0.07    -0.33

As far as I can see, the only 'color' is due to the cool color of the paper 
(Premium Glossy) progressively showing through the ink as the ink load gets 
less and lighter (1 is 255/255/255 with no ink, so just the color of the 
paper). Can other people see color changes with the more or less random 
variations in 'a' readings from -0.58 to +0.21?

Hello everybody

I am baffled.

Some of you have reported that there seems to be some "coloration" in their 
Epson 2400 B&W prints.

I have never seen any in mine.

Just to be sure, I just scanned a  Advanced B&W Mode "Warm" print on Epson 
Premium Glossy (Epson 4870, Vuescan, 600 DPI, Color Photo). It is dead 
neutral even at a magnification of  600 per cent.
