How to scale production with multiple flexo printer machines?

Comprehensive Guide to Flexo Printing Machines: Troubleshooting, Scaling Production, and Choosing the Right Equipment

Flexographic printing is a versatile and efficient method widely used in packaging and labeling industries. However, like any complex machinery, flexo printers can encounter various issues that may affect print quality and production efficiency. This guide addresses common problems, strategies for scaling production with multiple machines, and offers insights into selecting the right equipment, highlighting the advantages of Keshenglong and Shinko brands.

1. What Are the Common Issues in Flexo Printing?

Flexo printing machines may experience several issues, including:

• Ink Smearing or Set-Off: This occurs when ink appears smudged or transferred to the back side of the substrate or the next print. Possible causes include insufficient drying, excessive ink film thickness, or a poor drying system. Solutions involve increasing drying temperature or airflow, reducing ink volume, or using faster-drying ink.

• Pinholing: Small, unprinted dots within solid ink areas can result from low substrate surface tension, high ink viscosity, or dirty anilox rollers and plates. Treating the substrate surface (e.g., corona treatment), reducing ink viscosity, and cleaning anilox rollers and plates can help mitigate this issue.

• Foaming or Bubbles: Tiny bubbles or blisters in the ink film may arise due to excessive agitation during ink mixing, improper defoaming, or pump cavitation. Adding defoamer, using low-shear mixing, and adjusting pump pressure are recommended solutions.

2. How Can I Scale Production with Multiple Flexo Printing Machines?

Scaling production with multiple flexo printing machines involves:

• Implementing Servo Technology: Retrofitting existing machines with servo drives can enhance precision, reduce maintenance, and improve changeover speeds. This upgrade can extend the press's life by 5–10 years and improve print quality without the need for new equipment.

• Optimizing Workflow and Layout: Designing an efficient workflow and machine layout minimizes downtime and maximizes throughput. This includes strategic placement of machines, streamlined material handling, and effective scheduling.

• Standardizing Processes: Developing standardized operating procedures for setup, maintenance, and quality control ensures consistency across multiple machines, facilitating easier scaling and training.

3. What Should I Consider When Purchasing a Flexo Printing Machine?

When selecting a flexo printing machine, consider the following factors:

• Print Quality Requirements: Assess the machine's capability to meet your desired print quality, including resolution, color accuracy, and consistency.

• Production Volume and Speed: Ensure the machine can handle your expected production volume and speed requirements without compromising quality.

• Substrate Compatibility: Verify that the machine can accommodate the types and sizes of substrates you plan to use.

• Maintenance and Support: Consider the availability of technical support, ease of maintenance, and the machine's reliability to minimize downtime.

• Cost of Ownership: Evaluate the total cost of ownership, including initial investment, operating costs, and potential return on investment.

4. What Are the Advantages of Keshenglong and Shinko Flexo Printing Machines?
