Manual TECHKON DENS

Measurement on solid density patches:
In  this  example  the  measurement  has  been 
taken on a Yellow 

solid density 

patch.

DENS  recognizes  the  type  of  process  color 
and displays it as a color patch symbol. 

The  density  value  is  a  value  without  a  unit. 
It corresponds to the amount of ink applied 
on the paper surface. The higher the density 
value the higher the thickness of the ink layer. 

The  correct  density  value  is  dependent  on 
the  printing  parameters  (paper,  ink,  printing 
process). Usually, density values are between 
1.00 and 2.00.

Description of the measurement functions

The  current  measurement  function  is  indicated  on  the  right  side  of  the  display.  A 
switch to the next mode is done by pressing the MODE button. Thus the measure-
ment functions 

D

D %

and

 T %

 can be selected.

2.1 Measurement function D: Automatic density and gray  
balance measurement in reflection

TECHKON DENS comprises the essential functions related to density measurement. A 
very practical feature is the 

Automatic Density

 mode. By a push of the DENS button 

the relevant measurement values are displayed. Depending on the type of measure-
ment patch this can be:
