In Flexo, companies are looking to print higher quality. In that regard, the average screen count is reaching 1200lpi, with cells between 2 and 3u. This is delicate and requires a very special device to clean thoroughly and safely.
Understanding Our Foil Test Tip Trick
If you have an ultrasonic technology system, there is an easy way to see if it has the potential to damage the Aniloxes.
Tear off a strip of tin foil and vertically insert for 20 seconds. If you pull out the sheet and there are pin holes in the foil, the system has the potential to damage an Anilox.
If you own an Alphasound unit, conduct this trial and you will see no holes in the foil. This will showcase that the sound is even and safe for Anilox cleaning.
The spikes of sound within a milli-volt range are small. Yet, it is the incessant spiking of every few seconds that will erode a cell wall over time. It may take months or years, but if the spikes are in the machine, they will punch holes in the tin foul. Thus indications, the potential for roll damage.
This is a rudimentary way of safely checking your machine.
