2nd Srurface
I believe he is refering to sub-surface backpainted acrylic
signs/plaques. I have done these for years, provides an elegent look and prevents kids from picking off vinyl. Clear acrylic with mirror image cut vinyl or digital prints on clear vinyl applied to backside of acrylic then back painted (bulletin enamel), after paint is dry I always apply a layer of opaque vinyl over the paint, I mount these with foam tape, VHB tape and or Silicone and have never had a problem with then failing.
Correct!
This is the type of
sign we produce in large volumes. I posted this to get a consensus on what you have done to assist or assure they are the most durable once hanging in the field. Also, to get feedback on how the types of
signs have failed.
I print a mirrored image on a Roland CCVP (clear adhesive) then apply that to the backside of non-glare plex. They do provide a very durable
sign with a higher perceived value.
Through my experience so far when they fail it has just been by way of the DF tape or adhesive used to adhere the imaged panel to a backer or wall once installed. Simply put the
sign adhesive on the CCVP is pulled from the backside of the plex creating viods or pockets seen from the face of the
sign. Two ways this has happened to me in the past are the use of silicone which waits about 6 months then begins to contract (powerfully) and pulls the print. The other is not applying enough DF tape to a
sign and essentially not distrubuting the weight of the
sign across enough surface area of the panel. This causes too much stress in the areas that have the tape which then delaminates the print from the
sign face.
I hope this helps explain it all. I am trying to give my boss some confidence that more
signs dont keep coming back for fixn.
thanks guys!
