Facts About Cleaning Anilox Rolls

To increase the lifespan and improve the performance of your anilox rolls, you must clean them every time you use them. Otherwise, the ink can dry inside the cells, which decreases the print quality and forces you to replace the rolls sooner. While cleaning the roll may sound easy, it can be quite challenging. Here is some more about anilox cleaners and how to use them properly. 

Use a Good Cleaner

Several different cleaner options are available, ranging from water to chemicals. One good option is to use an alcohol-based cleaner. The next best option is to use a chemical cleaner. Chemical cleaners are available as both liquids and powders that you mix with water. 

Set Yourself Up for Success

Before you begin cleaning your anilox rolls, you need to make sure you set yourself up for success. The first step is to gather your cleaning liquids. Ensure they are within the appropriate pH range for your anilox material. Otherwise, you can damage the roll. Additionally, make sure the cleaner you have is environmentally friendly and not a harsh chemical. This can help you protect the environment and your anilox rolls. The last step is to gather the brush you need to apply the cleaner. Steel brushes are most common for ceramic rolls, and brass brushes are perfect for metals. 

Use the Proper Technique

The first thing you need to do is apply the cleaner to the roll and let it soak. Then, take your brush and clean the surface. Do this with a circular motion and firm pressure. Keep the roll wet while you are performing this step. 

After cleaning, rinse the roll with hot water. Wipe it dry with a roll wiper or other type of lint-free cloth. Check the roll for cleanliness and repeat if necessary. Once it is clean, be sure to wipe all of the excess water from the surface. Make sure you wipe away any moisture that has gotten into the crevices of your roll. Then, allow the roll to air dry the rest of the way while in a vertical position. Complete the process by storing the roll in a safe location after it has dried. 

You need to clean your anilox rolls if you want them to last. While this may sound like an easy task, doing the wrong thing can do more damage to your rolls. Following the tips in this guide is a great way to start cleaning your rolls.
