Some of the most common cleaning methods for anilox rollers include soda blasting, ultrasonic cleaning, and laser cleaning. These methods have been proven to be the most effective and efficient way to clean anilox rollers. However, it is important to take the time to determine which method is best for your particular case.

Chemical Cleaners
Generally, anilox rollers come into contact with inks, lacquers, and other cleaning agents daily. During this time, the roller accumulates a buildup of limescale deposits that can affect the print quality.
Chemical anilox cleaners aim to remove ink and other contaminants from the anilox roll. The process involves applying an appropriate cleaning solution to the surface of the anilox roll and then wiping it off. Chemical cleaners come in different formulas and are designed for specific applications.
Anilox roller cleaning can be a messy and time-consuming process. Therefore, it is important to have a care and maintenance program that outlines the proper handling and storage of anilox rolls. In addition, a regular cleaning program can help prevent damage to anilox rolls.
When using chemical cleaners, you should wear safety glasses and rubber gloves. You should also be sure that the chemical cleaner you are using is not harmful to the skin. You should also ensure that you properly clean the anilox roll after the cleaning process is complete.
Ultrasonic Cleaners
Several options will meet your needs, whether you’re looking for an ultrasonic anilox cleaner for your press or a solution for your daily maintenance. Ultrasonic cleaning machines are environmentally friendly and have no major safety concerns. They are also very easy to use.
Ultrasonic anilox roll cleaners are an effective way to reduce the downtime of your press. They can also help extend the life of your rolls. Ultrasonic cleaning machines can clean up to 12 rolls at a time. In addition, they are fully automated, which makes set-up and tear-down a breeze.
Anilox roller cleaning is done by loading the anilox roller into an ultrasonic cleaning tank and applying a cleaning fluid. The transducer inside the tank converts the ultrasonic frequency electric signals into high-frequency mechanical vibration. This creates hundreds of millions of water bubbles around the anilox roller.
Ultrasonic cleaning produces millions of bubbles imploding on the roll’s surface. This action agitates the cleaning chemistry on the microscopic level, removing contaminants and waste from the anilox cells.
Laser Cleaners
Using a laser cleaner for an anilox roller is a fast, safe, and user-friendly method. Unlike other methods, laser cleaners are fully automatic. They can clean multiple aniloxes at the same time.
This type of cleaning uses low-wattage lasers to vaporize coatings, adhesives, and ink. It also uses auto-focus to adjust to the size of anilox rolls.
Anilox rollers need to be cleaned at least twice a year. Most conventional cleaning methods should clean aniloxes better. These cleaning methods leave a residue on the anilox roll and can contaminate the ink.
A laser cleaner is the most efficient method for cleaning anilox rolls. The laser will clean dried ink from the anilox cells, remove caustic chemicals or varnish, and restore pick-up volume. It can also remove residue from the cylinder’s surface.
In addition to being safe and user-friendly, laser cleaners can clean multiple aniloxes simultaneously. This allows operators to clean without having to stop production from cleaning.
