I think people call them Digi stamps or Digi Stamping as a coined phrase just as in the UK they say they are "Hoovering" when they are actually using a vacuum cleaner of any brand . Hoover is a brand of vacuum cleaner , but everyone knows what they mean
Neither of these are the completely accurate names or terms , but we all know what the person means .
Most people know that printing a Digital image is not the same as applying ink to a piece of engraved or etched rubber or polymer material and transferring that image to paper
However, the results from both processes can be equally beautiful.
