I had ask awhile back about printing plackets on an auto and got some great answer's, I don't do alot of plackets but had an order I could tear thru quicker on the auto instead of the manual press. Today I think I might have found a cheap fix without buying all new pallets, I got some old rubber from one of my old pallets, cut it in half (giving me two pc) and cut a slot 2" wide by 5" long down the middle and put a little glue on the pallet and stuck it down works like a charm. The buttons fall in the slot just enough to make a nice full pass without any damage to the screen what so ever, thought I pass this on, just incase no one has thought of it yet.
