However, I haven't used anything that is a likely substitute for Hahnemuhle Photo Gloss Baryta, even though it scratches somewhat easily and has OBAs. My conclusion was that I'd very likely be essentially equally happy using only Palo Duro Softgloss Rag going forward. Last night-after noting that Hahnemuhle's website said that Photo Silk Baryta was discontinued, and while trying to decide whether to order up a stock of it-I spent some time looking at and comparing my prints on that paper, Canson Platine, and Red River Palo Duro Softgloss Rag. I experimented with Barytas but their susceptibility to scratching put me off so I switched to Platine type papers instead. Note one error below-the Ilford does contain OBAs. Hoping to include in testing, the new Canson Baryta Photographique II and Photographic II matte versions, for example, but none of my suppliers have the new papers yet. ![]() My research project at Aardenburg Imaging for 2020 is to look more closely at these OBA and TiO2 induced yellowing issues in the Baryta class of inkjet media, but I'm off to a very slow start due to the availability issues here in the U.S. They contain other whitening pigments like TiO2 as well. ![]() Many of the so-called Baryta papers do not have a traditional 100% baryta whitening layer. OBAs in paper core are less prone to cause significant yellowing in the image bearing layer, for example, than OBAs in a coating layer containing TiO2. Also, OBA comments like "very low" are not all that useful because they don't tell us where in the material the OBAs are located. Otherwise, it's impossible to compare them on whitepoint properties and/or OBA fluorescence. The manufacturers should really give media color properties in CIELAB values. It's a dead ringer for Hahnemühle Photo Silk Baryta, IGFS, etc., so probably being coated at Felix Schoeller in Europe, and perhaps now discontinued along with the others noted. Innova Exhibition Photo Baryta also contains OBAs. So, am I missing any widely-available baryta photo papers? Do you think any chart entries are incorrect? And maybe most importantly, do you have any comments on why you do or do not like certain baryta papers? (4) Weights range from 300 gsm (Hahnemühle FineArt Baryta Satin and Red River Palo Duro Baryta Fiber) to 350 gsm (Hahnemühle Baryta FB). 0.4mm (Hahnemühle FineArt Baryta and Moab Juniper Baryta Rag). 0.3mm (Canson Baryta Photographique II Satin and Epson Legacy Baryta) to 16 mil i.e. Several other baryta papers claim "very low" OBA content. (2) Several baryta papers at least claim to be OBA-free: (a) Hahnemühle FineArt Baryta Satin, (b) Hahnemühle Photo Rag Baryta, (c) Ilford Galerie Prestige Gold Fibre Silk, (d) Innova Exhibition Photo Baryta, (e) Moab Juniper Baryta Rag, and (f) apparently-the information on the website is not totally clear-Red River Palo Duro Baryta Fiber. (1) (a) Only Hahnemühle Photo Rag Baryta, (b) (apparently) Ilford Galerie Prestige Gold Fibre Silk, and (c) Moab Juniper Baryta Rag are 100% cotton (d) Canson Baryta Prestige is a mix of (apparently mainly) alpha-cellulose with (apparently less) cotton and the rest are 100% alpha-cellulose. ![]() I can tell you no manufacturer lists specifications for all of those. I'm not positive how to assess / compare "brightness", "whiteness", "gloss", "opacity", and similar specifications. Note that different manufacturers quote different specifications, and sometimes appear to address the same basic specification in different ways. I've compiled a little chart, taking information from the paper manufacturers' specifications, with some basic comparisons of some common baryta papers. Semi-subjective properties are certainly important, and I'm interested in your opinions on those, but what follows tries to be a reasonably-comprehensive listing with some basic objective data. ![]() The discussions have covered the recent lack of availability of many baryta inkjet papers, most of them being alpha-cellulose instead of cotton rag, many of them having OBAs, and new ones replacing old ones. Judging by recent threads, there is significant interest in baryta inkjet photo papers.
