I tried a sample roll a few weeks ago. Definitely needs to be coated, for instance wiping gently with a dry cloth transfered coloration to the cloth, and I didn't have to press very hard to cause abrasions. And very easily damaged with a moist cloth.
Very punchy image, similar to Lyve, punchy print fans will like it.
Very rigid feeling substrate and a rather unusual texture that was more "pebbly" than "weavey" but still in the canvas ballpark. Don't have any samples where I am now, sorry.
I also didn't like the way light coming from my behind me hazed the uncoated surface. Would definitely coat it if only for viewability.
But the basic claim for not needing to be coated was not really vindicated. A little tougher than your average uncoated canvas, but the problem exists that people have come to regard coated canvas as a lot tougher than uncoated Crystalline really is, and that could lead to problems in the field with cleaning attempts.
Does anybody know why they pulled it?
