The Definition Of An Original Print

'Proofs either in black or in colour, drawn from one or several plates, conceived and executed entirely by hand by the same artist, regardless of the technique employed, with the exclusion of any and all mechanical or photomechanical processes, shall be considered original engravings, prints or lithographs.
'Only prints meeting such qualifications are entitled to be designated Original Prints.' Third International Congress of Plastic Arts, Vienna 1960

When the edition is complete the plate is cancelled by scoring with an etching needle.
