Now that I am printing a "full-sheet" 2x3 or 3x4 sign, I want to know if there is any problem in applying this vinyl directly to the PRIMED MDO. Since we would normally coat-out with paint, isn't putting on a coat of vinyl doing the same thing?
I'll still be priming/sealing the edges, so what, if any, would be the problem with just applying the "decal" without putting a "finish" coat onto the MDO?

Hiya Gene, I'm sure it would work with proper cleaning & prep, but I wouldn't trust it. My thought is it's like putting vinyl on flat latex paint. It may stick for a while, but for how long? I would assume that you're looking at going after development and job site sings? If so, for the extra $15 - $20, I would go with RTG and not worry about sealing the edges. Or, offer the client the option of getting trim cap.
Havin' fun,

All the cheapo shops around here apply vinyl to the primed faces. You can tell because after about 4-6 months the signs white area is washing off but the vinyl is still there.
I wouldn't trust it, but that's me!

Hmm, okay. These are factory pre-primed MDO boards, the gray stuff.
I already had some in stock, so I figured I could use it without an extra step (which I AM willing to do after I get a consensus). Thanks guys & girls.
Someone out there has done this I'm sure. Total failure???

Why not just get that paint on and be done with it? Unless you have a lot of time to kill redoing if it happens. (That is if the customer doesn't kill you first-if you're tied up with another important life situation or customer when he wants it redone). I've never, never had success getting vinyl to stick to latex and I swore I would never even entertain the thought again. just me 2 cents, good luck experimenting.

Personaly Gene, if your taking the time and effort to seal the edges and you have to paint the back why not paint the front and just be done with it. Why even risk it.
It is a ply-wood, primer is just that a primer, not a finish coat. if time is that much of a concern I'd just use a different substrate.

Gene, All day every day. No problems for better part of 10 years. Make sure you use a perm adhesive vinyl (Oracal 3640 or above or comparable) prime edges after and seals vinyl edge also. Not to be used for anything long term as the grain will pop within weeks. Downside? you'll be making too much money using up excess stock with your new printer.

Use your excessive amount of color-match fubars and mixing mistakes (if you have 'em) to paint the primed MDO. Not that I have any experience with digital stuff. Paint mix-ups, well of course I do! love....Jill

Evidently, if not finish coated, MDO means Mimaki Does Over.
Otherwise, it means Medium Density Overlay. It is plywood with a resin saturated Kraft paper overlay, thus presenting a smooth surface for lettering or concrete forming.

Pre-primed panels sounds like a good start. You can save time by top-coating with gloss latex. Several people told me that on this BB a few months ago, and they're right. If time is not essential, then I'd do as Jill said and get some use out of the FUBARs.
