![]() CANON PHOTO PLUS PAPER FREEThe presence of OBAs will cause the paper to glow brightly blue, while OBA free papers will remain dull. Testing for OBAs is simple enough if you have a UV flashlight. Papers without OBAs can be properly profiled with any spectrometer, namely the inexpensive ones like the SpyderPRINT or ColorMunki Photo. If the device includes a UV-cut filter or a source that produces no UV light (such as a white LED), then the resulting profile is incapable of compensating for the shift that the increased blue from the OBAs creates. ![]() Where OBAs can cause problems is with generating profiles using a reflective spectrometer. Moreover, in a framed fine art situation, where the print is behind UV blocking glass, their inclusion is largely pointless. OBAs aren’t inherently bad, but they can be problematic. These agents increase the apparent brightness of papers by absorbing UV light and reemitting it as blue light in the visible spectrum. I’ve tested this paper for the use of optical brightening agents (OBAs). This is obviously a good thing for printers, as it means that you don’t have to worry about the paper’s response is more stable with changing light levels. This in turn means that the paper shouldn’t change color or brightness with fluctuations in UV levels in the environment. CANON PHOTO PLUS PAPER PROIt’s also the same brightness as the Pro Premium Matt paper.īecause the brightness is less than 100, it doesn’t appear that Canon is using Optical Brightening Agents (OBAs) in this paper. It’s not as bright as the Pro Platinum (98 brightness) and is a little brighter than the Photo Paper Plus Semi-gloss (91 brightness). CANON PHOTO PLUS PAPER ISOIt’s given on a scale of 0 to 100, where 0 would indicate that the paper reflects little to no light, and 100 indicates the paper reflects all of the incident light.Ĭanon lists the brightness of the Pro Luster paper as 92 using the ISO standards for brightness. Brightness and Optical Brightening Agentsīrightness quantifies the amount of incident light the paper will reflect. To be honest, after spending a lot of time looking at the various qualities of various papers, at least to the extent I can, I’m not at all any more clear on what Canon’s logic is with their papers. However, looking at things like weight, surface texture, image quality, and so forth, it’s not entirely clear that at least some overlap in the Plus and Pro lines. The best I can work out, is that Canon’s paper matrix looks something like the above chart. If you go on price, the difference might not be so much? If you go on the names, you’d suppose that one should be better than the other. On the other hand, if you look at the pricing many of the Plus and Pro papers are priced identically or nearly identically.įor example, Canon’s two semi-gloss papers are the Photo Paper Plus Semi-Gloss, that lists for $99.99 for 50 A3+ sheets the other is Photo Paper Pro Luster, and it lists too for $99.99 per 50 A3+ sheets. The names of their papers indicate there are at least 3 distinct non-fine art lines: Photo Paper, Photo Paper Plus, and Photo Paper Pro. The Plus Semi-Gloss is one, the other is the Photo Paper Pro Luster.Ĭanon’s matrix of photo papers is, quite honestly, confusing. At the same time, it didn’t knock my socks off so much that I needed to order box instead of trying something else.įortunately, Canon offers two verities of semi-gloss papers. After having made a dozen or so prints on in, it’s not a bad paper. I already tried, and spoke briefly about, Canon’s Photo Paper Plus Semi-Gloss. Solving the surface reflection issue is a matter of moving to a more matte surface. It’s also relatively expensive for a mid-level paper, at just under $3 for a 13 x 19 print. The biggest of those are that it reflects everything in perfect detail. However, being a gloss paper, it does have some limitations. It’s a gloss paper that I find generally works quite well for reproducing color and detail at the level at which I’m printing. ![]() In the past, my mainstay paper has been Canon’s Photo Paper Pro Platinum.
