Hi, i had this terrible problem. I printed the graphics in paper mate and I used transparent topsheet. After pressing the paper did not bont to the topsheet but the ink did. I am wondering what could be the best way to fix this problem. Instant glue? Or taking top shit and graphic paper away sanding a little it the top and putting a new top sheet?
By the way. Does aomebody use the same method as me for the graphics?
Topsheet Delam

using an inkjet or laser printer with a regular plastic topsheet won't work as far as my tests showed. all my sample pieces delaminated.
i'm now printing on regular matte paper (no coating), then apply a coat of white acrylic paint to the underside of the printed paper (to prevent epoxy from seeping through and then i apply several coats of polyurethane varnish to protect the graphic.

my paper is completely matte. it feels like regular paper. the one i use is called Sihl TrueColor but others work as well, just make sure they don't have a PE-coating or similar.
the acrylic goes on the side that touches the glass. bonds well. polyurethane varnish is commonly used on this forum especially by the guys that have veneer topsheets.

Cf as a top sheet?
Hello chrismp, I'm friend of Jose, we are together building our skis. We notice that the matte paper are not embedded of epoxy, not even the side with out the graphics, is the top sheet what makes that the graphics pull out? can you post us the link of your tests?
Have you tried to use one or two layers of CF as a top sheet?, instead or with clear top sheet? in Chile we found bi-directional cf in 90° and 45°, both in 5 oz.
Cheers.

so the whole paper delaminates from the layer of glass below it? i don't have photos of my test pieces, but all of them delaminated between the printed side and the topsheet.
sure, you can use CF as a topsheet, but with CF as well as with any sort of topsheet that has epoxy exposed to sunlight it is better to apply some sort of varnish to protect the epoxy from UV light. you could use some layers of glass as well if you don't want a plain black topsheet like with CF.

i would not suggest any paper as an outside layer.
use rice paper, graphics will still show but most unprinted parts of the paper will be virtually invisible, and if you do that, cover that with at least a thin layer of glass like a 4oz surf glass and wet that out too.
are you using a topsheet or no?
