Best phd programs in sustainable development - Red river paper palo duro

overall slope of the Red curve from 1 to 30 looks similar in both graphs, the curve shape is not quite the same. The key observations here are: (i)

OEM better separates the mans black hair from the black background; (ii) OEM better separates shadow detail in the clothing, and (iii) OEM renders a slightly wider contrast range between the mans forehead and the darker parts of the. For the custom curve (M2) in relcol, the slope.4, while for the OEM profile (M3) it.65, again a large difference predicting superior deep shadow detail separation for the OEM (M3) profile using relcol Rendering Intent. Similar but different is a recurrent theme in the paper business these days. Key distinguishing features from the profiles data are: (i) the gamut of the M3 profile is 19 larger than that of the M0: 718K. The custom profiles fall in-between. L*17 for the M0 profile; the White points are the same and the chroma of the Black and White points differ very little. Relcol BPC reduces the difference between the results of these profiles, but it is still material. Red River Palo Duro Softgloss, Canon Pro1000 Printer. Its Black rendition and overall color vibrancy is very good for a matte paper, especially with the OEM M3 profile. RR Palo Duro Etching, Epson P-800 Printer, OEM M3 vs Mark M2 Profiles. The Average dE for the M0 profile.71 with Variance.12, while the Average dE of the M3 profile.49 with Variance.97. In his previous review he looked at the Moab papers and in this review he covers the Red River line of papers. My further work involved two things: (1) Black and White luminance testing for both my profile and theirs, and (2) making both color and B W prints using both my profile and theirs, then comparing. For the custom profile, the whole relevant range is below.0 with most of it below.75, which is very good. Now, leaving the world of curves and data, and turning to the test phd images for Moab Somerset Museum, I was going to include comparative scans of these photos, but I decided not to because the differences between them printed in Relative Intent are too subtle. Turning to the grayscale performance, Figures 66 and 67 show the results of the 21 Neutrals test for the Epson P800 and Canon Pro-1000 printers respectively. Red River Palo Duro Etching, Epson P800, M2 Profile, dE Graph. Red River San Gabriel Baryta Semigloss, Basic Data Gamut volume is right up there in the big league at about 972K for my custom profile and 947K for the Red River profile, not a significant difference, and both very large. The overall conclusion I draw from this testing is that I would select to use the OEM profile over the custom profile, regardless of what the numbers say about profiling accuracy (probably heavily influenced by the disconnect between profile creation and profile results measurement technologies. Over the relevant range for this PK paper (L*595 neither the Luminance nor the Chroma dE values exceed about.25, and the range of variance from one five-level interval to the next seldom exceeds.75, so the perceptual impact would be minimal if any. Recalling that the flatter the curves and the closer to zero the dE values the better, the OEM outcome looks rather unappealing over good parts of the curves. RR Palo Duro Etching, Epson P800 Printer, OEM M3 Profile Data. Its paper-white looks neutral-warmish, measured paper white being a bright L*98.2, b*0.2 (ever so slightly warm whereas a* is -0.7, a little bit cool). Finally, while I could not do it myself, I have been provided good reason to believe that if one measured the results of an M3 profile with the same polarizing-equipped spectrophotometer, the resulting data would show much greater profile rendition accuracy (lower dE) than reported. However, with the M3 profile, tonal distinction starts at a blacker level of L*1213, where after the measured values track the linear scale quite well, but at about 4 levels brighter. M3 dE Grayscale Graph relcol Looking at this same graph using Relative.I., the preference for the M3 profile holds. With this paper, if one print using Relative Intent with BPC (Figure 95) there isnt a lot of difference in the rendering of shadow detail. Unlike for igfs, there is no reported longevity testing data for this paper yet; however, the company is of the view that longevity should show as satisfactory once it does get tested because of the standards it adheres to, per their website: Archival grade materials;. I have more to say on M3 profiling just below.

At that level of Blackness in a real photo one wouldnt notice a b value of about. M2 versus M3 Profiles, epson P800 Printer, figures 79 and 80 show the graphs for abscol and relcol respectively. Output, interesting things to know about ink jet papers. Ii The Black point of the M3 profile is L12. Beyond which there is a close linear fit with the file reference values of 1 57 and the Total Average dE over the same range. Red River Palo Duro Softgloss, the cause of the high L dE values is that the measured deep gray values are considerably brighter than those in the test image reference file till about L4550. The largest being about 867K for the OEM profile in the Canon Pro1000 and the narrowest being about 818K for the OEM profile in the Epson P800 1 input, somehow 0, moab Somerset Museum M3 Profile Turning to full grayscale tonal rendition. RR Palo Duro Etching 602K, maximum printed white is around L98 for the four profiles just a tad brighter in the P800 than in the Pro1000.

Palo Duro, etching - 100 Cotton Fine Photographic Inkjet.Palo Duro, softGloss Rag - 100 Cotton Fine Photographic Inkjet.Red River Papers new, palo Duro, etching is a fine-art inkjet photographic paper designed to create the look and feel of fine-art darkroom prints.

Red River San Gabriel Baryta Softgloss The paper performs well for profiling accuracy. Then as ink jet coating started getting into main stream. The other colors are above, the paper mills started doing their own coating for little more than the cost of the base paper. Red River Palo Duro Softgloss, for the time being, the blackest tones look a trifle blacker in the Romans16 photo. The rest are inbetween, the Average dE for the 24colour test being. But avita printing with Relative Intent, epson P800 Printer, epson P800 Printer, epson P800 Printer, red River Palo Duro Softgloss, from this 2 Careful inspection of the B W segments in the Atkinson test image indicates that there is less deep quartertone separation in the.

See column I above.Lets spend a moment on why.For the M3 profile, L* brightness is consistently several levels above the reference curve, and shadow detail would begin to differentiate from about input value L*10, much as predicted from the profile analysis.


Red River Papers New Palo Duro Etching - Digital Photo

The M3 profile starts one level darker and finishes one level brighter than the M0 profile so slightly higher incremental tonal separation from the slope of the M3 curve, but its subtle.The characteristics of the M0 and M3 profiles are illustrated in Figure 90 (M0 was a better fit for the custom profile with this paper).The Baryta and the Semigloss components of the name are more self-informative.
