Ltd - Servicing Works
There are many advantages to regular servicing of machinery.
Regular servicing enables early identification of any changes in
the machinery and monitoring of wear and tear. This in turn can
reduce the likelihood of large repairs and unplanned prolonged machine
down time, which can cause administrative problems in a busy studio
or workshop. Any damage to the machine found at the time of service,
can be assessed and recommendations made.
Regular servicing will also enable the machinery to work to its
best ability. Adjustment of the machine to prevent problems such
as paper crease and blanket creep will enable a professional print
quality, vital for any print workshop or studio conducting end of
year exams. Re-levelling of platens can vastly improve the usability
of the Relief presses such as Albion and Columbian Presses and this
can be undertaken during the service as necessary.
Checking of items, which may have become damaged over time, is
essential to make sure the equipment is safe for you, your students,
other printmakers and those with access to the studio, a vital tool
in risk management.
Having a professional print engineer visit the workshop to service
your equipment has the added benefit of providing the operator with
a refresher, in the setting and daily maintenance of the individual
press, necessary for safe usage and to prolong the life of the equipment.
The following are a number of symptoms that may indicate a service
