I have only used Alumigraphics, but from samples, they are pretty similar.
Tip 1: You must use the take up system. Run material out to the reel or use scrap material. We use scrap banner material, cut off about two inches of the liner and apply it to the banner. Run it through the machine until it gets webbed up. It's best to do this on a large table and make sure the scrap piece is squared up to the roll or else your machine may through skew errors.
Tip 2: None of the application tapes we've tried will stick to the textured materials so you'll have to be patient trying to lay graphics with holes or odd shapes that stick out. In a pinch we've used thin strips of the same material to hold pieces together.
Tip 3: It's extremely hard to cut on a plotter. In fact on my last job, we had to hand cut 800sqft+ of it because we couldn't get the machine to read the marks and we'd already used about $500 worth of material for testing and samples. Square cut is really easy to do by hand but ours were water drop style graphics. Was too late to get it cut on a partner's Esko. Also, be prepared to go through a few blades.
Tip 4: Installation is really simple. Get some knee pads or a foam pad because you'll be crawling around. Slit the backers before you get on site if possible. I start by positioning a graphic, get my helper to pull the liner back about few inches while I'm finish installing a graphic that's already been prepped. I typically press it down by hand or roll it as some is pulling the liner off. Squeegees will wear down pretty quickly on the gritty stuff. At an absolute minimum use a roller and some heavy pressure to seal the edges. I actually use cotton gloves to push the material into cracks. On square graphics and simple shapes, you can pull the whole liner off and lay it in position.
Tip 5: A light spray of Frog Juice or Clear Shield can help protect against ink abrasion and help prevent dirt from sticking, but don't expect much. As with all floor graphics, if a vehicle turns a wheel on top of the graphic, it'll sheer it right off the ground.
