Proper flexographic plate storage plays
a vital role in achieving high quality flexographic printing. Therefore, the
following points should be noted in the daily storage process:
(1) Keep it in a place free from sunlight
and UV lamp irradiation.
(2) The ambient temperature is controlled
at 5°C to 35°C.
(3) It should be cleaned the ink and fully
dry on the surface as soon as possible after printing.
(4) The plate should not be placed on top
of each other (use paper or buffer material to separate between flexo printing
plates).
(5) Storage room should maintain good
ventilation.
(6) Use a cleaning agent that does not
swell the resin.
High printing pressure or hard rubbing of
the plate can cause damage to the flexo printing plate. Therefore, during and
after printing, cleaning of the plate should be avoided to make the plate
broken.
We know that the water-based ink and
solvent-based ink, after printing for a long time will be dry and cured. Once
cured, the ink is difficult to dissolve. Hard wipe cleaning will cause the
plate breakage. Therefore, after printing, the plate should be cleaned and
fully dried before the ink is cured and placed in a well-ventilated place for
storage. Proper plate washing time and storage environment can prolong the use
of printing plates and reduce the cost waste caused by flexo printing plate
damage.
