A comprehensive guide to selecting the right parts washing equipment for the print industry.
The print industry relies heavily on the smooth functioning of machinery and equipment to produce high-quality prints efficiently. To ensure optimal performance, it is essential to invest in the right parts washing equipment. Parts washing not only enhances the longevity and reliability of the machines, but also improves the overall print quality.
In this article, we explore the benefits of parts washing in the print industry and recommend suitable types of machines based on different printing processes.
Benefits of parts washing in the print industry…
- Improved Print Quality: Contaminants can negatively impact print precision and clarity.
- Increased Equipment Lifespan: Removes dirt, ink residues, and debris, extending the life of critical components and reducing downtime.
- Enhanced Efficiency: Clean parts operate more efficiently, reducing energy consumption and optimising print production.
- Cost Savings: Reduces the need for frequent repairs and replacements.
- Compliance and Safety: Promotes a safer working environment and adherence to industry regulations.
- Environmental Responsibility: Using eco-friendly parts washing solutions demonstrates a commitment to sustainable practices.
So which technologies are best for which type of printing?
Flexographic Printing:
Flexographic printing involves flexible printing plates and is commonly used for packaging materials, labels, and newspapers. Recommended parts washing equipment:
- Ultrasonic Cleaning System: Ultrasonic cleaning is highly effective for intricate parts, such as anilox rollers and doctor blades. The gentle yet powerful cleaning action ensures optimal ink transfer and print quality.
“The new anilox roller cleaner consistently delivered results within tolerance 100% of the time – something not previously achieved with solvent spray methods.”

- Aqueous Spray Cabinet Washer: For cleaning larger components like ink trays and press components, an aqueous spray cabinet washer offers efficient cleaning and is environmentally friendly.
- Manual Aqueous Parts Washers: Many of our customers combine manual parts washers with an ultrasonic cleaner. Ideal for ink trays and larger components, but also an option prior to using an ultra sonic cleaner. This is a good way of minimising the need to change the sonic bath as regularly.
Offset Printing:
Offset printing relies on transferring ink from a plate to a rubber blanket before applying it to the printing surface. For this process, the following parts washing equipment is ideal:
- Automatic Aqueous Parts Washer: Aqueous systems are an environmentally responsible option for many offset printing components, particularly ink trays, rollers, and general press parts. They help reduce reliance on solvents and provide consistent cleaning results.
There are, however, a few considerations to keep in mind:
- Ink Compatibility: Aqueous systems work best with water-based inks. Oil-based inks may require a tailored approach or an alternative cleaning technology.
- Plate Sensitivity: Metal plates can be moisture-sensitive, so aqueous cleaning should be applied carefully to avoid damage.
- Drying Requirements: Thorough drying is essential before cleaned parts are returned to production.
Where aqueous cleaning is less effective, Metalwash can recommend alternatives such as ultrasonic or solvent-based systems, ensuring the right technology is matched to each part of the process.
- Ultrasonic Cleaning System: While some components in offset printing, such as ink trays and printing cylinders, may be suitable for cleaning in an aqueous parts washer, other delicate or intricate parts may require more specialised cleaning methods, such as ultrasonic cleaning, to ensure thorough and safe cleaning.
Digital Printing:
Digital printing involves transferring the digital image directly onto the printing surface, eliminating the need for plates. Suitable parts washing equipment:
- Automatic Parts Washer: An automatic parts washer with programmable cleaning cycles can effectively clean various parts used in digital printing equipment, including print heads and ink supply systems.
- Ultrasonic Cleaning Tank: For delicate print heads and components, an ultrasonic cleaning tank can gently remove ink residues and debris without causing damage.
