Menu: Measurement conditions
When the “soft key” in the right section of the lower bar is activated, a window opens
where you can set the measurement conditions which dene the parameters of the
measurement, e. g. which lter will be applied.
The measurement conditions 4. – 18. are described in detail together with the corre-
sponding measurement functions in chapter 2.
1. The device has an integrated Polarizing l-
ter, which can be activated or deactivated by
a push of a button. Polarizing lters compen-
sate for measurement dierences between
glossy and non-glossy surfaces (e. g. freshly
printed and dried sheets). The technical stan-
dards in Europe recommend the use of such a
lter for densitometric measurements. On the
other hand, colorimetric measurements (e. g.
L*a*b*-measurements) should be taken with-
out a polarizing lter.
By selecting Auto from the menu, this will be
taken into account and there will be automat-
ically the right lter setting.
2. There are two possibilities for dening the
White Reference: Density measurements
usually are referred to the white value of the
paper printed on. Colorimetric measurements
refer to an absolute white reference which is
supplied as a ceramic tile on the charging
console.
By selecting Auto from the menu, there will
always be the right setting according to the
measurement mode which is selected.
3. Depending on the regional technical stan-
dards dierent Density Filter settings are
required. SpectroDens as a powerful spectro-
photometer has the great advantage that any
lter specication can be exactly calculated
out of the spectral data. There is no limitation
known from conventional lter based densi-
tometers with xed lters built in.
In Europe lter ISO E is to be selected as the
standard lter.
