3.6.6 Measuring paper

 

For paper measurements, automatic color selection allows for    

 

quicker work, as no switching between the CMY colors is required.  

 

Color contrast is very slight with tones under 0%, so that manual  

 

color setting is recommended. For measurements on black, the    

 

color (K) must always be selected manually.

 

The iCPlate2 is equipped with a video camera, which measures the  

 

geometrical dot size, relevant for plate readings. For prints, the    

 

densitometric dot size needs to be measured, as this measurement  

 

corresponds to the visual impression. Therefore, the iCPlate2 is    

 

not the ideal device for measurements of the dot area on paper.   

 

Nevertheless, it can be used  for visual dot analysis of prints.

3.6.7 Measurement Values

 

3.6.7.1 Dot area

 

This value represents the area coverage of the measured patch.    

 

With the image analysis algorithm, dust and image errors are 

 

eliminated.

 

3.6.7.2 Screen ruling

 

Depending on the settings, the screen ruling is displayed either in  

 

Lines/inch or Lines/cm.

 

Important:

 The screen ruling is not shown for FM screening and for middle    

 

tones, especially for chain dots in AM screening. 

In a regular screen

, the  

 

 

screen ruling 

will always be shown if the dot area has closed dots 

 

(highlights and shadows).
