21step.tif

21step.tif

2011-07-23 by Mel

I have printed off the 21step.tif using the QTR Graphical Interface with the following hardware, ink, paper and preset.

Epson 1290
Epson Enhanced Matte
UT2 inks
Neutral preset

I have used the X-Rite 810 for reflective measurements on the Visual setting and have recorded the following readings from the step wedge:-

100 1.59
95 1.43
90 1.30
85 1.17
80 1.05
75 0.97
70 0.88
65 0.80
60 0.72
55 0.66
50 0.59
45 0.52
40 0.46
35 0.41
30 0.36
25 0.31
20 0.26
15 0.21
10 0.17
5  0.12
0  0.08

The 810 is calibrated and gives the correct readings of 0.09 on the white patch and 1.79 on the black patch of the calibration plaque.

My question is, are the readings what I should expect of the paper/printer/ink/densitometer combination ?

My original post omitted the printing resolution of 1440 Super.
I have printed a further step wedge using a resolution of 2880 and record very little difference as shown below.

100 1.60
95  1.42
90  1.28
85  1.13
80  1.02
75  0.95
70  0.86
65  0.78
60  0.70
55  0.63
50  0.55
45  0.48
40  0.42
35  0.37
30  0.32
25  0.28
20  0.23
15  0.19
10  0.15
 5  0.11
 0  0.08

Incidentally I have heard it said that Epson Enhanced Matte is the same as Epson Archival Matte - this is not so as the Enhanced Matte is noticably a brighter white than the Archival Matte, although giving the same densitometer reading of 0.08. The Enhanced Matte is also considerably more expensive, certainly here in the UK. 

I would still appreciate the forums opinion as to whether thes readings what I should be getting.

It's fine. Copy and paste these numbers in a .txt file and open it with QTR-Create-ICC to get a profile. Numbers look typical of a Matte paper with ABW mode.
Epson printers seem to behave exactly in the same way with wether you select Archival Matte or Enhanced Matte.
