We are doing are first Conastoga Trailer with the vinyl tarp. We have the screen printing inks, and are set to go. But I do have a couple questions.
What type of roller is better - the foam rollers or a reg good roller? We are painting through a mask....and wondering what the best way of getting the mask off is. Dennis did a test paint with the mask, let it dry, peeled the mask off...it wanted to peel up some of the edges. Any tips?
Thanks!

Are you using vinyl inks? They are extremely agressive. I've never used a mask but have taped top and bottom lines and never had a problem. You might want to remove the mask right away. I'm sure somebody will chime in about the roller but I'd be willing to bet vinyl ink will cause problems with a foam roller.

Thanks George, we are using Nazdar Inks,S250... that they recommended. We do need to thin it down with the thinner. That was our thought to on the foam roller. We are going white over black tarp....and not sure if we will have to do 2 coats on it.

I've done a few, but white over black is hard. Yuk! The danger in using a roller is the stuff will dry very fast and stringy, and the thinners will break down the foam or the glue holding the roller to the core.
Brush - yes, or I've airbrushed it-you don't have the lifting problem at the edges then-there's more of a 'break'
The 2nd coat of white might want to make a mess of the first though... and it might take three coats. I'd brush it and work wet and fast with a medium softish brush-possibly use retarders in the mix also, and allow longer drying time.

I'm with some of the others, in that you've got your hands full here.
Some thoughts: The solvents in the ink are going to attack the glue on the foam roller, and quite possibly the glue on the back of the mask..making the glue want to bleed under.
Normally, you'd want to remove the mask soon, to prevent bleed and leave a smoother edge. Now, since you are most surely going to need multiple coats, you're going to have to leave the mask on for awhile. This could tend to want the lift around the edges of the letters, making jaggedy edges....could.
I'd be tempted to do this with an airbrush or touch-up gun, and spray the first couple coats, thinned with a fast-dry reducer. Hopefully, that would "seal" the edges of the mask, to prevent bleed. Then, go with a couple more coats of less reduced ink, to finish it off. Then, carefully remove the mask, as soon as possible.
We'll be wishing you best of luck on this one.

Stay a bit light on the edges, or they will buckle & pucker, though...

Pat, If you bought the Super Opaque White, even thinned It should cover well. It's opaque printed through a 235 count screen mesh which is much much thinner than anything a roller would lay down. I'd give a letter a few fast passes, than some slower, passes with less weight on the roller and see how it looks. I'd use a short nap roller and if things are covering OK, pull the first letter mask after doing a few more letters. That should tack up pretty quickly. Do NOT roll or fold that tarp for a couple of days though. You are putting a whole lot more solvent on there than you would be if screen printing and you what that fully dry.

I would tint the white ink with either black ink (to make a very light grey) or blue ink (to make a very light blue) it will cover a lot better than a pure white colour and look just as good !! You might even get away with just one coat !!- good luck.

Thanks everyone for your help! We did it! We ended up using Nazdar inks, white, and applied two coats...using paint mask, and peeling it off very carefully when not quite dry all the way. It turned out great. Our customer was very pleased. We did the cab of the truck too, printing the Ranger Logos on our new HP Latex Printer, and added some cut vinyl as well.
