Four different scanning Color Electronic Pagination System (CEPS) devices were tested to study their conventional and Grey Component Replacement/Undercolor Addition (GCR/UCA) tone and color response in the 4 color Positive Acting Offset Lithographic printing process.

A new depiction of the full tone reproduction characteristics is presented for several different levels of GCR/UCA and conventional printing.
