Do I need fine filtration?

We will help you to find out and at the end of this presentation you will know !

Why filtration

Operation

Conclusion

ContentDampening solution fine filtration

4

Economic pressure demands increased machine availability

Stable and reproducible printing quality demand consistent dampening solution

IPA-reduced offset printing requires ideal dampening solution quality

Special printing processes (e.g. white ink) lead to further dampening solution contamination

IPA-free

Conventional, varnish or UV printing

Why filtration?

White ink

Paper dust

If your dampening solution / dampening pan looks like this, how can you control the printing process?

Why filtration?

6

Dampening solution dirt can consist of various components

such as ink, paper, germs, varnish, etc.

Contamination varies with every print job

Particles always vary in size distribution, by means the

contamination is not homogeneous

Filtration Principletechnotrans 2 step deep filtration technology

Step 1:Cartridge pre-filter

Step 2:Deep-bed main filter

The pre-filter serves to remove coarse particles and the contamination from the main fine filter

The main fine filter has a very high capacity for collecting dirt

By-pass filtration …

… does not effect the flow and circulation to the printing units

… is consistent and attuned to the filter elements

… is a continuous process also when press stops or production

ends

… filter quality is continuously monitored by pressure sensor

beta.fOperation alpha.f Filter maintenance and life time

Pre- and main filter are the only consumables

Filter life time depends on contamination, and contamination

depends e.g. on ink and paper quality as well as the application

itself (special colours, little or a lot of spray powder, etc)

First time filtration users should clean the entire dampening

circulation system (dampening tank, intermediate tank, pipes,

trays)

Filtration quality is controlled by filter mash size / filter

characteristic

In general the pre-filter has to be replaced more often than the

main filter

12

Permanently clean and clear dampening

solution ensures consistent printing

conditions and enables high print quality

Continuous filtration process reduces the

requirement for dampening solution

exchange and thus increases productivity

and machine availability

Significantly reduction in dampening

solution exchange cut cost for additives,

disposal and overall press operation

Continuous filtrations results in a clean

dampening solution system (unit, trays, etc.)

and thus reduces maintenance costs and

press down time.

ConclusionYour benefits with technotrans fine filtration systems

Conclusion

Do I need fine filtration?…if your dampening solution is dirty

…pans and pipes require a lot of maintenance

…the printing quality shall be further stabilized

…you will go for IPA reduced or free printing

…your target is to reduce waste

…the press down time shall be further reduced

…reduced consumption of press chemicals

…general improvement of quality

…increase productivity

If you say yes to one or all of the above, technotrans alpha.f is one solution to achieve your target
