It also kinks easier that 100% cotton, which is why I prefer the cotton. Some of these products do feel like a "paper" to me others like "card stock" or "cardboard."Īlpha Cellulose is what feels like cardboard. Freestyle Sales even has one 50 percent alpha cellulose 50 percent cotton.įor me, some of the distinction is much less quantifiable. Thus, if I have it right, Canson Baryta Photographique is produced of alpha cellulose stock Platine Fiber Rag of cotton. In addition to the OBA issues just cited, one big difference is some of these papers are 100 cotton others are made with alpha cellulose fibers. With the bounty of affordable fine art inkjet papers we know have, it does take a PhD to discern all of Hahnemuhle and even Canson's offerings. Unfortunately, some paper types always contain OBAs, like all Metallics and most Barytas (I've found one, Moab, that doesn't contain OBAs).Ĭompanies are in love with them, even those, like Breathing Color, who make loud noises against their use, but use them heavily anyway and then lie about it (their Lyve canvas is advertised as OBA free, and the coating is, but the canvas base is saturated with them). It's too confusing, that's why I try to avoid OBAs altogether if possible. As such, and even though there may indeed be a lower chemical concentration of OBAs in media like Photo Silk Baryta, they are typically more vulnerable to OBA burnout. However, the OBAs in PhotoRag Ultrasmooth are located in the paper core underneath the image receptor layer(s), but the OBAs in the Photo Silk Baryta are most likely contained in one of the coating layers (e.g., the baryta subbing layer). Yet Hahnemuhle classifies it as having moderate OBA content whereas Photo Silk Baryta is classified as low. Hence, for example, Hahnemuhle's Photo Rag Ultrasmooth paper does well in Aardenburg light fastnesss testing and is classified by its UV-included/UVexcluded Lab measurements in the Aardenburg database as having Low OBA fluorescence. The location of the OBAs within the media is also very important. Yes, Photo Silk baryta is listed by Hahnemuhle under "photo" rather than "fineart" which, IMHO, seems to be a totally superficial way of classifying these media because you will also find non RC alphacellulose OBA containing media designed to mimic traditional photographic papers under the "fineart" category as well.Īnother thing to be aware of is that Hahmemuhle's OBA classification (.e.g very low, moderate, etc" is potentially misleading because it doesn't necessarily correlate with the light fade resistance of those OBAs. It's still for sale at the major Canadian suppliers. I don't know about it being discontinued, but it's under the "Photo" section of papers rather than the "Fine Art section", lumped in with the RC media The FineArt Baryta Satin is listed as "new" so I assume it replaced it, which is why I linked to the new data sheet. That paper is no longer listed on Hahnemuhle's web site: Which indicates "very low" levels of OBA like many of the other a-cellulose baryta papers by various manufacturers. Which indicates "very low" levels of OBA like many of the other a-cellulose baryta papers by various manufacturers. the paper reference in the title is the following: It's also a "look-alike-print-alike" counterpart to the classic Ilford Gold Fibre Silk paper as is Epson's newer "Legacy Baryta" paper.Īccording to the data sheet the Baryta doesn't have any OBAs, but I haven't tested it personally: Photo Silk baryta is has an alphacellulose base with a semi-gloss coating. "Rag" in Hahnemuhle's naming convention is reserved for cotton base, so Photo Rag Utrasmooth is a cotton fiber paper with a full smooth matte finish coating. One is matte and contains OBAs and one is glossy and doesn't contain OBAs:īoth contain OBAs.
