Zero reference and target reference calibration
The FLUO measures relative fluorescence using a non-fluorescent reference
(0% or substrate) and a target fluorescent reference (100% target fluorescent
ink layer). Perform the following steps
1. Zero the FLUO on an area of the substrate clean of fluorescent ink or
use the black reference of the calibration target as zero reference.
2. Measure the 100% reference on a sample reference from your ink
supplier or your in house reference.
3. Measure on various locations of your printed product and check the
amount of fluorescent ink in relation to your reference.
Measure the zero reference
Position the FLUO with the aperture onto a non-fluorescent surface, for
example onto the substrate without fluorescent ink. Press down the ‘down’ key
and push the device to the front until zero appears in the LCD.
All measurement channels will be zeroed simultaneously.
Measure a single solid reference [C 0]..[C 1]
If the average number in the settings is set to zero, the calculation of an
average is disabled.
Position the FLUO with the aperture onto the fluorescent reference
surface, for example onto the substrate with fluorescent ink. Press down the
‘up’ key and push the device to the front until 100 appears in the LCD.
The max reference measurement measures all channels simultaneously and
sets the max. fluorescent signal for each illumination (near and far) separately
to 100%. The channel with the highest fluorescent response will automatically
be displayed. In case the Intensity mode is selected there will be set the
Intensity of the reference sample to 100% for near UV and for far UV.
