LIQUID POLYMERS
General characteristics
Exemplary equipment
technology
for flexo plates
Many years ago, Asahi started systematic research work in the field of photosensitive
liquid polymers. Today the work is still continuing and in the area of flexo
printing excellent results on paper and corrugated board alike are being achieved
around the world with Asahi’s APR liquid photopolymers. This proves that plates
made from APR materials are suitable for many applications in flexo printing.
APR flexo plates can be made to a very high quality, economically with polymer
reclaim and within one hour by a process that is most compatible with the
environment.
The range of APR plate processing systems, with each system offering proven
technology and new developments, ensures this.
Each of the equipment systems - ASF 1216 and AWF 110 - consists of three units
with the following functions:
Lamination
Exposure
Plate transfer
Liquid polymer recovery
Wash-out
Finishing
Drying
Liquid polymer supply

FUNCTION
1
ASF 1216 E
Laminating/exposing unit
[ 1 ] The liquid photopolymer is
laminated over the negative film,
and exposed.
ASF 1216 P
Processor
[ 2 ] The exposed plate is transferred to
the processing unit.
[3 ] In the first module the plate is
squeegeed, recovering the
unexposed liquid polymer.
[ 4 ] The plate is then washed out in a
water/soap solution.
[ 5 ] After wash-out the plate is postexposed
submerged in water.
[ 6 ] After postexposure the plate is
dried.

ASF 1216 E
Laminating/exposing unit
Lamination/exposure processes
All functions and process sequences of the unit can
be input and checked via a programmable controller
and visualized on a colour display.
Flexo plates can be laminated to individual thicknesses
of 1.7– 7.0 mm at increments of 0.01 mm.
Exact plate thickness tolerance within +/- 30 µm
3.94 mm is ensured by electronically
monitored laminating speed and temperature
of the lower glass plate.
Two light-metering devices provide the basis for
consistency of exposure results.
A removable light-reduction screen enables the
operation to obtain extremely steep relief shoulders and
pronounced intermediate depths.
The upper lid of the ASF 1216 E unit
(for exposing the back of the plate) is lifted in horizontal
alignment. This ensures optimum handling of the
laminating-exposing frame from all sides.
The capping system makes it possible to laminate two
liquid polymers, differing in Shore hardness, one on the
top of the other.
[ 7 ] The recovered APR liquid polymer
is mixed with fresh APR liquid polymer
and used for further platemaking.

ASF 1216 P
Processor
The ASF 1216 processing system consists of five
modules operating independently of each other. Each
module (except the postexposure module) has a cylinder
on which the APR plate is clamped. Plate transfer
from one module to the next is a manual operation.
All functions and sequences are controlled via a freely
programmable controller. A built-in modem enables
swift checking of all function sequences should a
problem in operation (remote control) arise.
Plate transfer module:
The plate transfer operation to the processor is made easier
thanks to the transfer drum mounted on rails between the
exposure unit and the processor.
Photopolymer recovery module:
The recovery process is automatic. The unexposed APR
photopolymer is removed from plate surface and protective
film with a rubber squeegee – hot air supporting the process.
The APR photopolymer thus recovered is automatically
recycled into the photopolymer supply tank.
Wash-out module:
The aqueous wash-out solution is sprayed on the plate surface
through nozzles, rinsing it of unexposed polymer. Automatic
metering of additional fresh concentrated wash-out solution
after each spraying process increases consistency and life of
the wash-out bath considerably.
Finishing module:
The APR plate is horizontally carried in the module by a
chain system and receives its UVA/UVC post light treatment
submerged in water. The postexposure water is automatically
regenerated after each cycle.
Drying module:
The wet plate is quickly and efficiently dried using a
hot-air knife and hot air flow.
ASF 1216 T
Photopolymer supply tank
Two liquid base photopolymer tanks with a volume
of 200 l each provide a high capacity for continuous
working.
A capping-photopolymer tank with a volume of 36 l
provides sufficient capacity for continuous working.
All the photopolymer tanks are equipped with
dedicated heater and the base polymer tanks in addition
with an agitator. Recycled and fresh APR photopolymer
are therefore mixed homogeneously and without any
problem.
An air-controlled pressure system ensures a uniform
flow of photopolymer between liquid photopolymer
supply tank and laminating bucket of the ASF 1216 E.
