Abstract
Improvements in coating colour management in a paper mill
will enable significant waste reduction and prolong the
running cycles of coating colour batches. It is well
understood that it is important for a mill to regularly
monitor coating colours and to have an up-to-date
reference database regarding the properties of the used
coating colours. This "best practice" simplifies the
evaluation of quality issues which may occur and
consequently lead to serious problems. A database can be
used for the evaluation of both the raw materials and
ready-made coating colours. Currently, the quality
control in coating colour kitchens is often performed
with a simple viscosity measurement, such as a Brookfield
viscometer, and in most cases, both pH and dry solids
content after coating colour make down are also
monitored. However changes in coating colour properties
during different process steps should also be measured in
order to understand how to improve the long term
performance of a coating colour. An optimized coating
colour will not only help to achieve a mottle free print
quality but also to reduce coating colour waste and to
improve the efficiency of the coater.
