Breathing Color Pura Smooth paper with "Chromata white"
2013-08-17 by Paul
This is a potentially interesting paper. See http://www.breathingcolor.com/action/bc_shop/224/ Breathing Color has a coating technology they call "Chromata white." This has been used on canvass, but their (relatively new, I believe) "Pura Smooth" matte paper is the first use of this technology on a matte paper. It's a paper that might be very useful to me and others printing with Eboni-6 inks as well as other inksets. The company claims the paper is the first bright wide matte paper with no OBAs. My testing is consistent with this. UV light indicates no OBAs, yet the Lab B is less than one. My current favorite inkjet paper for Eboni-6 is Epson Hot Press Natural. This is, in part, because it looks the most neutral of non-brightened (no OBA) papers. So I used Epson HPn as a comparison. Reading the two papers at the same session (same calibration), the Pura Smooth Lab B = 0.4 while the Epson Hot Press Natural Lab B = 2.45. (Of course there are lots of OBA containing papers with lower Lab B's.) The other visually interesting aspect of Pura Smooth is that the paper Lab A = 1.8, compared to Epson HPn Lab A = 0.5. This more "selenium" "pinkish" hue is one many like. I do. It's one of the things about my old favorite Premier Art Smooth BW (has OBAs) that I like. The Pura Smooth Lab B rise with Eboni-6 when printed with the 7800 is a bit more than the Epson HPn -- 3 v. 2.5. The absolute max. Lab B of the Pura Smooth is 0.7 units less than the Epson HPn -- 3.76 v 4.46. Visually, the Epson looks a bit yellow in comparison. The Pura Smooth dmax is a bit less -- 1.67 v. 1.71. When viewed under a magnifier, the Pura Smooth had a bit more microbanding than the Epson paper, particularly a few positions at relatively high ink loads. By keeping the ink limits below these points for the inks where the issue showed up, the final print was very smooth, essentially equal to the print on Epson paper. The net reaction of more than one casual viewer is that the Pura Smooth paper and image look better with Eb6 than does the Epson Hot Press Natural. I will definitely be looking more closely at this paper when I run out of my current Epson stock. Breathing Color sells trial rolls (17" x 20') for $25. They claim this is their cost, and it's less that half the cost of pre-cut sheets. I would be most interested in anyone's experience with this paper or the Breathing Color "Chromata white" coating technology. Paul www.PaulRoark.com
