Is Your Canvas OBA Free? It NEEDS to Be!!!

P2C Says "NO" to OBA's! (Optical Brightning Agents)

Pixel2Canvas has always worked to ensure that the canvas artwork that we produce will last beyond our lifetime. This means that we use only the BEST products, from the canvas we print on to our frames and our backing Tyvek.

We view the collaboration of your imagery and our artistry to be the highest possible representation of your art. We take pride in what we do!In the past, people have asked all types of questions about our product, but one question is coming up more and more these days. It concerns the use of OBA's or Optical Brightning Agents in our canvas prints.

We can say with confidence that our canvas is, and has always been OBA free! But you might ask...why does it matter? OBA's are used to artificially enhance the brightness of a canvas media. They are typically found in less expensive canvas products. The problem is that over a short period of time...These OBA's break down and can cause significant deterioration of the image. Problems such as yellowing in white areas is a common problem when using OBA canvas. Even when protected with a UV coating, these additives in the canvas will cause a faster deterioration over time.

This is why we use only stable OBA free canvas for all our canvas prints!

So the question then comes up...how can I tell if my canvas is OBA free? Simple. If you have teenagers in the house, or on your street, you can likely find a way to obtain a BLACK LIGHT. Pass the black light over your canvas. If you see really no reaction, your canvas is OBA free. If it lights up like a white shirt in Mr. Toad's Wild Ride, the canvas is coated with OBA's and you will see it glow or flouresce. This glowing is a clear indication that your canvas was printed on OBA enhanced canvas.

If you are interested in further reading, check out Wikipedia.org : Quote "The Global OBA production for paper, textiles, and detergents is dominated by just a few di- and tetra-sulfonated triazole-stilbenes and a di-sulfonated stilbene-biphenyl. These are subject to fading when exposed long term to UV, due to the formation of optically inactive stilbene cis-isomers found at the center of the molecule.""...continued exposure to UV containing light will actually cleve the molecule and start the process of degredation."

The long and short of this story is that you want to make sure your canvas is OBA free...if you want it to LAST! When we say our canvas is archival and is made to last around 100 years, we really mean it!

We pride ourselves on being a GREEN SHOP. Our canvas is OBA free, our wood is cut from renewable, USA resources, and our coating is non-solvent and biodegradeable.
