The Lorentzen & Wettre Elrepho 07x / 07xE Series Paper Spectrophotometers are the paper industry's own
spectrophotometer. It measures colour,
brightness, opacity and whiteness of
paper, paperboard, tissue, pulp, coating
inks and fillers. The visual appearance
for a printed product is of crucial
importance and is expensive to achieve.
The Lorentzen & Wettre Elrepho 07x / 07xE Series Paper Spectrophotometers automatically measure according
to the conditions specified by the user,
e.g. D65 illuminant, C illuminant,
or a 420 nm cut-off filter.
The Lorentzen & Wettre Elrepho 07x / 07xE Series Paper Spectrophotometers are designed to make laboratory work easier. A sample
is placed on the measurement table, and then automatically
positioned against the instrument's measurement aperture.
For opacity measurements, the black cavity is controlled
automatically. In fact, the measurement software controls
everything
L&W Colour-Brightness software, is optimized for shift testing
and has complete user interfaces for identification, measurement, and reporting. Grades with limit values and target values can be set as required. The software reports most optical
characteristics. Calculations can also be implemented to meet
the user's needs.
The software automatically measures according to the
conditions specified by the user, e.g. D65 illuminant,
C illuminant, or a 420 nm cut-off filter. Measurement results
can be copied to other programs by a simple copy and
paste function. Alternatively, data can be saved in an Excel
compatible file. Sample identities can be retrieved from (and
measurement results sent to) other databases using standard
commands and tools.
Residual ink measurements of recycled pulp and paper
are made on a sheet and opaque pad according to the
ISO 22 754 and TAPPI T 567 standards respectively. This
measurement can alternatively be made on an opaque pad
only. This latter method is not standardized. An alternative is
to measure the ink elimination between two process stages
with the INGEDE method.
The program features a number of ways to display the
results graphically. The trend diagram is used to monitor the
production over a longer period, while the L*a*b* plot shows
the colour coordinates for a series of samples. The reflectance
curve provides important information about colour dyeing and
the fluorescence of the sample.
The Lorentzen & Wettre Elrepho 07x / 07xE Series Paper Spectrophotometers have been manufactured with with traceable calibration in accordance
with the ISO's hierarchy for photometric calibration and
UV calibration at level C and D65. The software has an
easy function for checking the calibration, or making a new
calibration, when necessary. A large number of reference and
working standards, with target values can be stored.
The Elrepho 071 Lorentzen & Wettre Paper Spectrophotometer with Measurement Table may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
