calibratioN:

 

The integrated multi-channel color sensor is calibrated by a 

 

white  calibration.  After  performing  a  white  calibration  the  

 

device is long term stable. We recommend to make a white  

 

calibration  before  every  measurement  series,  to  ensure  the  

 

device is calibrated correctly. 

 

StaNDarDS:

 

The  measurement  device  is  manufactured  according  to  the 

 

recommendations  of  the  technical  standards  DIN  5033  part  

 

1-9, CIE and ISO 5-3. 

 

The accuracy of the device is checked during the manufactur- 

 

ing by spectral measurements on color samples which were  

 

measured and certified by the German Institute for Material  

 

Testing (Bundesanstalt für Materialprüfung, BAM).

 

The calculation of densitometric values is according to the for- 

 

mulas and tables of ISO 5-3 and the handbook of standardiza- 

 

tion of the German Printing and Media Industries Federation  

 

(Bundesverband  Druck  und  Medien  e.  V.)  and  Fogra  (For- 

 

schungsgemeinschaft Druck e. V.).
