PROS:

  • no knowledge required

CONS:

  • expensive and time-consuming personal supervision
  • dependent on the person
  • lighting conditions related
  • uncontrolled metamerism
  • no repeatability
  • initial swatch-book inaccuracy
  • instability of color samples (aging, dirt)
  • different substrate / OBAs
  • unpredictable issues of opacity, overprints and tints 
  • undefined matter of issues
 

PROS:

  • numerically expressed color differences

CONS:

  • expensive and time-consuming personal supervision
  • uncontrolled metamerism
  • initial swatch-book inaccuracy
  • instability of color samples (aging, dirt)
  • different substrate / OBAs
  • unpredictable issues of opacity, overprints and tints 
  • instrument precision and stability, inter-instrument agreement issues
 

PROS:

  • numerically expressed color differences
  • stable color definition
  • exchangeable color definition
  • the possibility of remote control

CONS:

  • limited color definition
  • only one lighting condition specified
  • uncontrolled metamerism
  • unpredictable issues of opacity, overprints and tints 
  • instrument precision and stability, inter-instrument agreement issues
 

PROS:

  • numerically expressed color differences
  • stable color definition
  • exchangeable color definition
  • lighting condition independent
  • controlled metamerism
  • the possibility of remote control 
  • trackable instrument precision and stability
  • optional inter-instrument agreement harmonization

CONS:
