yes. Remember, we stated how playfields are made. All inserts are inserted and glued in. Then they are sent through a plainer which sands off about 1/16-1/8" off the top of the field to make it flat, level the inserts to the playfield and scuff the playfield to get ready for screen printing so the ink sticks. Then it's screen printed. Then cleared.
So i'll repeat this for the 10th time in this thread alone. The reason it ghosts at the edges is because.........wait for it..........wait............wait for it........... Because of the Wood, expanding and contracting to the edges of the plastic insert. *Gasp*. So here we go again. Lets review.
Expanding and contracting of the wood
Plastic insert does not expand and contract
There for, creating a fault line on the edges of the insert. Allowing air to sneak in the back, up under the clear. and......>TA-DAAAAAAAAAAAAAA. Ghost pocket.
Now factors that can cause and accelerate this process. are.
Humidity and temp changes
Insert cutout too large allowing slop in the insert
Insert cutout too small allowing the insert to be forced upwards
Shrinking of the insert from the plastic shrinking (takes years and decades for this to happen)
insert made to the wrong spec and made to small or too large
silicone somehow got on the playfield
gremlins snuck into the factory and started banging on the inserts from the backside with a drill bit and a hammer.
