Why automatic plate cleaning<br />
// Save time & money<br />
The cleaning of the printing plates takes a lot of time during your production process. We asked<br />
some customer without an automatic plate cleaning system, how much of the yearly time they waste<br />
for washing.<br />
20-25% of the effective machine production time<br />
is used for cleaning.<br />
20-25%<br />
This means for example a production with 2 shift operation<br />
with 3000 h/year has 600-750 h/year only for cleaning, when<br />
the printing machine is not productive.<br />
// Why do I need to clean so often<br />
High volume of cleaning time<br />
There are 3 effective situations when a cleaning is necessary:<br />
• Cleaning after job set up due to dry ink<br />
• Cleaning after 3000-4000 sheets due to dust or dry ink<br />
• Final cleaning after the job<br />
// We can offer 2 solutions<br />
• Quick Plate Cleaner (QPC)<br />
The QPC is a machine integrated system which removes dry ink & dust spots without stopping the<br />
machine. A quick interim cleaning within 120 seconds is possible, with about 8-10 waste boards. A<br />
final cleaning is not possible.<br />
• Auto Clean System (ACS)<br />
The ACS is a machine integrated system which is able to make an interim cleaning within 6 minutes<br />
and a real final cleaning within 2 minutes with stopping the printing machine.
Quick plate Cleaner (QPC)<br />
// What is it for<br />
• Cleaning of specific dust spots on the printing plates on request of the operator during production<br />
Increases quality output and reduce stand still time of the machine due to dust<br />
• Continuous (automatic) cleaning of the printing plates during production<br />
Especially for fingerprints, reducing the stand still times of the machine due to dry<br />
ink on the printing plates<br />
• Quick plate cleaning of the printing plates at feeder stop<br />
Quick start of the machine after jam up or feeder stop. Waiting time for cleaning is reduced<br />
to a minimum; about 8-10 waste boards<br />
// How does it work<br />
The system consists of a moveable<br />
cleaning head with a rotating special<br />
sponge. The cleaning head is moving<br />
along the printing cylinder and removes<br />
dust and ink. The distance to the<br />
printing cylinder can be set in micrometer<br />
steps through the touch panel.<br />
After cleaning the printing plates the cleaning head is moving back to an integrated cleaning station<br />
where the sponge is cleaned for the next usage.<br />
// What are the specialties<br />
• The cleaning head is cleaned inside the printing machine<br />
longer usage of 1 cleaning head without exchange<br />
• The cleaning head is flexible to the printing plates thickness<br />
Less set up time for each job necessary<br />
• The cleaning head can be cleaned outside the machine<br />
Reduction of the spare part cost<br />
• You can add for final cleaning the Duo-Technik Final Cleaning Station (FCS)
Auto Clean System (ACS)<br />
// What is it for<br />
The goal of the ACS system is not only to remove dust spots or dry ink but to clean the printing plates<br />
to the ground. For this the machine has to be stopped for cleaning. Especially for long inline production<br />
lines this is interesting as the ink dries on each stop on the printing plates. This dried ink is only hardly<br />
removal with an inline cleaning system.<br />
You get:<br />
• Full cleaning of all printing plates in use in<br />
6 minutes<br />
• The 3rd sheet after cleaning is sellable<br />
• Quick final cleaning in 2 minutes with<br />
wet printing plates<br />
• Final cleaning of the printing plates parallel to<br />
the set-up of the new job<br />
• Defined usage of soap for cleaning<br />
• Always a clichés in a good condition<br />
// How does it work<br />
• With nozzles a soap/ water mixture is sprayed onto<br />
the printing plates<br />
• Special nozzles are used which block each dropping<br />
of water after stopping the spraying<br />
• A static brush for cleaning is placed underneath<br />
the nozzles<br />
• With a rubber lip the system is sealed for any water drops or waste water<br />
Cleaning station<br />
• A suction channel in between brush and lip is removing the waste water. For this each unit has a<br />
separate suction ventilator<br />
• A drying unit dries the printing plates after cleaning<br />
• A machine connection transfers the data of printing units and board widths used. This is preselected<br />
automatically in the menu<br />
• The operator can set additionally individual for each unit the widths<br />
• The water and soap is mixed with a separate mixing unit which is part of the delivery<br />
