You may be using a ink jet printer which tends to smear ink easy, you may need a laser jet printer. I use those avery full sheet shipping labels print and stick then cut, to remove I use a old hair dryer turn on low heat start heating it up using a razor knife get it to peel up then start peeling it off keeping the area I am peeling heated up and it peels right off. Just becareful the heat from that hair dryer can be hot and burn your hands, I use a pair of needle pliers to hold the patter as I am peeling it off till I get enough to use my hands with out getting hot. You can get a pack of 100 shipping labels on amazon for about 23 bucks, or go to a office place or even walmart and get a smaller pack of 10 for 4 bucks to try them out to see if it will work is what i did. Since then I veered away from the painter tape and glue.
