Hi Bill,
Just started using it in the past few months and have used a few rolls of 24 and a 44 inch roll for some test images for a large canvas job still in negotiations...
So far, no issues with the winding of the canvas and even uncoated. It stretches well and can easily be dry mounted in a press with excellent results.
I just liquid laminated several of our sample prints and that will add pop the colors and enrich the blacks, somewhat. I'm using an Epson 9800 with PK and both my client and pitchman both are impressed with the results.
The only issues I can tell you about are that the canned profiles I found for the 777 made the prints pink, thus I ran my own with a Munki and that profile is much better. After flood lamination, the prints did curl when they dried, but I was also pushing the limits by doing that process in an unheated and cold garage on a rainy day. Overall, though, the prints looked great after coating. I expect them to look even better once they have been pressed onto foam board.
Had Breathing Color responded to my inquiries regarding lamination and processing, perhaps I would have gone with them. But, as I said earlier, I get great support from Rick at Coastal Giclee in Monterey, Calif.
