Chapter
1 Maintenance after the Printing
3. Cleaning the Cylinder Section
A WARNING
Stop
the
crawl
operation before cleaning. Failure to follow this instruction
may
result in a
serious
injury.
The
materials that are used with the press have a high degree
of
acidity and alkali which have a negative effect
on
the
press. The use
of
these strong chemicals may cause the metal parts to corrode
or
rust, so proper maintenance
of
the press
is very important after finishing the operation for the day. Because the cylinder section greatly influences the printing
quality, proper maintenance should be done
on
it every day.
1) Clean the plate cylinder.
Maintenance Edition - 6
Take
off
the plate and under sheet from the plate cylinder after printing is
finished. Wipe off any stains such
as
ink, etching solution, and plate cleaner
on
the plate cylinder
surface
with a
cotton
rag
containing
water
and
cleaning solution.
Also,
when
using the
gauge
film with
the
plate cylinder,
take
off
the
gauge film and clean the plate cylinder at least once a month.
«NOTICE»
1.
Do
not use plate cleaner
to
clean the plate cylinder. When cleaning
the plate, be careful that the plate cleaner does
not
adhere on the
plate cylinder surface.
If
the plate cleaner adheres on the plate cylinder surface, wipe it
off
with a cotton rag containing water
and
cleaning solution immediately.
2. When using the gauge film with the plate cylinder, clean the cylinder
surface well
and
dry it completely before mounting the gauge film.
Also, mount the gauge film so that
it
contacts the entire surface
of
the cylinder.
If
there is
any
clearance between the film
and
cylinder,
water, etching solution,
and
the other chemicals will enter into the
clearance
and
rust will form.
3.
When the hydrophilic properties
of
the plate surface cannot
be
kept,
wipe
off
any
ink
and
oil with a cotton rag containing chrome roller
cleaner. Then wipe
off
the chrome roller cleaner completely with a
cotton rag containing water.
