Regarding the EZ Glide and coating.
I run 3-4 inches of leader, another inch or so as a trailer. You've got to open the spreader and feed the canvas, then close it and velcro it down. You then pull it through and lay it on a table. I use one table to hold the coater, the second is to lay the print out for initial inspection of the coating and to rework if there are any glitches. The back is virtually dry and I haven't found any issues with that surface.
Since the canvas is very floppy once it's pulled from the coater, my solution is to use cheap wooden dowels and cloths pins at each end then hang it up to dry it on a cloths line in my garage where I do this. With the dowels in place, there is little curling and problems of the wet surface getting dinged during the handling to hang them. It takes about 20-30 minutes for the laminate to dry and then they are good to go. Haven't had any issues with runs, just a few lumps now and then. I run the solution through a screen when I fill the tray so I have few problems with the solids that seem to fall from drips by the lid of the jug.
Once the print is pulled from the EZ Glide, they are mainly damp and not runny. The back is run through the coating system (flood coated), but is squeegeed, so there is little on that surface. They dry pretty quickly, but if you need to rework the print with a roller after pulling, you've got a little time. If I see a problem after coating the print (last prints at the end of the day), I simply run a second coat with a roller.
Since I don't have a lot of space, the largest I've coated is 44x60. I visited my canvas supplier earlier this week and his machine is designed for an entire roll at once. He was telling me that a new machine was on the way for beta testing in a couple of months which will handle sheets and rolls, different coatings and both canvas and paper. We'll see what happens.
