when to spray print protector?
« on: April 27, 2013, 05:46:56 PM »

before or after mounting?

I would think after is the best time since it might not stand up well to 190degree heat in a press. But I was wondering what people are doing.

To some extent all coatings with stiffen up the print surface in a way that causes surface texture to get squashed down during dry mounting, the surface testure loses the ability to bounce-back after being pressed.  No big deal if you are mounting smooth, matte prints.  But if your prints have a texture that is important to the presentation, at least some of that quality will be ironed-out during dry mounting, and much more so on coated coats.  So do post-mounting coating if texture matters.

I'm sure manufacturers' data sheets have information about allowable temperatures.  I have one wholesale customer who dry mounts my canvases, with the squash-down result.  But the Glamour II coating can handle whatever temperature he uses with his Fusion 4000 tissue, I'm going to guess it's around 190F.

The only temperature issue I even ran into with dry mounting inkjet prints is that RC papers will quickly delaminate around 230F, although most any kind of inkjet media can take 200F for at least 10+ minutes, on a press without excessive temperature swings.
