Gray Balance Targets are composed of Yellow, Magenta and 
Cyan tints balanced to produce a neutral gray when all the 
pre-press conditions are in control. 
Making press corrections for slurring, doubling, ink water 
imbalance, etc. are fast and easy with ink key adjustments 
without stopping the press or wasted paper or downtime.
