Anilox rollers are indispensable in printing machinery, yet prolonged use or immediate issues might lead to defects in print output. Here, we'll delve into prevalent issues such as scratch 

lines, abnormal wear, cell blockage, physical damage, and corrosion bubbles. We'll analyze their causes and provide effective solutions to tackle these challenges.

1. Scratch Lines

Cause Analysis: 

Scratch lines on the surface of an anilox roller occur due to hard particles mixed in the ink. When the doctor blade scrapes over the ink, these particles between the blade and the roller surface cause abrasions. These hard particles could stem from the doctor blade, metal fragments from pumps, dried ink, or impurities.

Solutions:

1.Install filters and magnetic blocks in the ink supply system to eliminate metal particles.

2.Maintain a clean ink supply system to prevent the formation of dry ink particles.

3.When using chambered doctor blades, ensure adequate ink flow to lubricate the blade, removing abrasive particles.

2. Abnormal Wear

Cause Analysis:

1.Uneven installation of the doctor blade, causing uneven stress.

2.Excessive stress or insufficient lubrication on the doctor blade.

3。Quality issues with the ceramic layer of the anilox roller.

Solutions:

1.Thoroughly clean the doctor blade clamp and backing blade before careful installation.

2.Enhance the quality of the ceramic layer on the anilox roller.

3.Improve lubrication methods.

3. Cell Blockage

Cause Analysis: 

Inadequate cleaning of the anilox roller after use results in the incomplete removal of debris.

Solutions:

1.Use a suitable magnification level to inspect the cleanliness of the cells.

3.Strengthen post-print cleaning of the anilox roller.

4. Physical Damage

Cause Analysis:

1.Direct impact with hard objects causing damage to the ceramic layer.

2.Improper cleaning methods and tool selection leading to damage on cell walls.

Solutions:

1.Exercise caution to prevent mechanical collision accidents.

2.When stored apart from the machine, use protective sleeves for the anilox roller.

3.Thoroughly understand various cleaning methods to select the most suitable, avoiding potential problems.

5. Corrosion Bubbles

Cause Analysis: 

Corrosion of the anilox roller's base material leads to surface warping and, in severe cases, localized ceramic layer detachment.

Solutions:

1.Provide manufacturers with information on the roller's usage environment for enhanced anti-corrosion measures.

2.Consider using stainless steel as the base roller material.

3.Use caution in cleaning to avoid strong acid or alkali chemical cleaners.
