Canvas Spraying
A few more thoughts,
Canvas brands, to consider, Breathing color and Lexjet, I would stay away from the Epson brands. Breathing color currently has only a matte canvas, however Bill Atkinson has prepared a very good profile for this canvas for the Photo K3 inkset. Lexjet has a glossy and matte version, it's in their Sunset line. I helped prepare the profile for the glossy canvas for the K3 photo inkset and so far it has seemed to work fine.
Spraying, if you print canvas, you will need to spray it mainly for protection from handling, but also UV and fading. The two products that I seem to get the most consideration, are Clearstar and Glamour II. Both are water based and both have glossy, and semi-glossy versions. The Clearstar you need for Canvas is the Type C, either glossy or semi-glossy. I would recommend you use a HLVP sprayer, Wagner makes a nice one, that doesn't require a compressor. I spray before I stretch.
I prepare the print for Gallery wrapping, where the image will continue around the sides. I have an action that stretches the outside 2" of the image and then allows for the wrap. There are a ton of other ways to do this, but so far I like the results of the action. Depending on the size, I go with a 1" to 1 3/4" border.
I prefer to do a 40" x 60" on canvas. This is a size that is just easier to work with in Canvas. By the time you add a matt/frame and acrylic you have a big piece of art to handle. I wouldn't use glass due the weight and danger of breakage. 40 x 60 prints require special matting as the largest mat board I know of is 40 x 60. Most times you will see a junction style matting where a piece is put in the center to cover the gap. Note, on the 44" printer if you are going to Gallery wrap, you will need to make the print 38 x 60 to allow for the wrap.
One other note, it's a know issue that Epson's large printers have a problem on the set vertical width of the print. Example, if you print a 30 x 40, where the 30" is going the width of the paper, then you most likely will get a 29.75" x 40" print. I picked up a solution of adding 0.1875 to the vertical before I make the print, only to the vertical height. This at least gets you enough material to stretch.
As for mat cutters, I still use a Fletcher 2200 and 3000. The 2200 will do a nice job but it is very critical on the material being as square as possible. I purchased the 3000 used and it's not perfectly squared, I finally gave up on that. I need to purchased a entire new head for it sometime. I like the 3000 for cutting, both glass and mats. SpeedMat is a nice solution, but at the time I made the purchased the 3200.00 price point was too high (cutter and shipping). But it does allow you to handle all the operations that the 2200 and 3000 do in one machine.
There are just some observations from my work with Canvas.
