Why do we need to care about the anilox rolls?
Anilox is the key factor in metering ink in the flexographic printing
process. To deliver consistent print quality from time to time, the
maintenance of the cleanness of the roll is critical as it dictates the
amount of ink to be delivered to the photopolymer plate and
subsequently to the substrate.
Poor maintenance of the anilox rolls not only leads to inconsistent
print quality due to ink plugging in the anilox cells but extra
wastage on the resources in the pressroom as well, this including
material(plate, ink,substrate), machine downtime(on-time delivery),
man power which all turns into extra operating costs. So, when is
the last time your press people struggled to get the correct ink
density while your customers are waiting for their order to be
delivered? Have you checked up the wastage in your pressroom can
be eliminated with a proper maintenance of the process control
including a predictable and consistent amount of ink?
Cells clogged with dried
ink will have a different
shape and, consequently,
a different ink volume.
This influences the print
quality and extra cost...

Keeping the Rolls Clean
Cleanliness is an important factor that directly influence the print
quality. Therefore, all anilox rolls should be cleaned after each print
job. Most printers claim cleaning with water does not give the
required results. Moreover, cleaning with water requires more
cleaning time as well as much water. This also results in large
quantities of slightly polluted water. Cleaning with cleaners may
lead to water being polluted more severely, but less water is
needed. Overall, this is more environmentally friendly and more
economical, since water needs to be processed regardless of the
degree of pollution."
