Substrate Options —‘Paper or Plastic?’

Plastic suppliers have to be extremely sensitive and responsive about dyne level, notes Robin Reis, executive vice president, Serigraph. "I don't think I've had to reject a shipment over a dyne level issue in a number of years. It's really become a non-issue as plastics become more available."

"If we do reject a batch of plastic, it's because of slime spots or other defects in the surface," Tenyer adds. "Some of these plastics are calendered, others are extruded, and sometimes the finishes can be inconsistent. There might be dust around the edges from a paper cutter that will get into the work."
