Setting Up the Kodak Process Control Densitometer
For complete instructions on setting up the Kodak Process Control Densitometer, refer
to the Operation Manual for the Kodak Process Control Densitometer, Publication Part
Number 635933, available from X-Rite (616) 534-7663.
Note
The Densitometer has 16 channels. Each channel monitors a single processor. Therefore,
it is necessary to dedicate and set up a channel for each processor in your department.
There are 4 parameters which should be monitored:
• Speed Index (S Index)
• Base+Fog (B+Fog)
• Customer Upper Density Point (CUDP)
• Developer Temperature (Temp
°
F)
Note
Contrast Index (C.Indx) does not need to be monitored.
It is recommended that the factory preset Densitometer value of “Dmax” be changed to
CUDP value to more accurately describe the variable monitored. For more information,
refer to the section “Determining the Customer Upper Density Point” on page 16–8.
