In the process of plastisol ink printing, the cleaning of equipment and nozzles is of paramount importance. It not only affects the quality of the printed output but also directly impacts the overall performance and lifespan of the equipment. Below are some practical tips on how to effectively clean plastisol ink printing equipment and nozzles.
I. Understanding the Cleaning Needs of Plastisol Ink
Plastisol ink, with its high viscosity and easy-to-dry characteristics, makes cleaning a crucial task. If not cleaned promptly, the ink can clog nozzles, solidify on equipment surfaces, leading to decreased print quality or even equipment malfunctions.
II. Choosing the Right Cleaning Tools and Chemicals
Using Professional Cleaners
To ensure effective cleaning, it is recommended to use specialized cleaners designed specifically for plastisol ink. These cleaners can effectively break down ink residues, minimize damage to equipment, and are relatively environmentally friendly.
Avoiding Non-Professional Products
It’s important to note that while there are chemicals available that can thin out plastisol ink (chemicals to thin out plastisol inks), they are not suitable for cleaning equipment and nozzles. These chemicals can potentially damage equipment components or compromise print quality.
III. Daily Cleaning Procedures
Regular Nozzle Cleaning
Nozzles are the most prone to clogging, thus requiring regular cleaning. Use a soft cloth dampened with an appropriate cleaner to gently wipe the nozzles, avoiding the use of hard objects that may scratch them. For inks with high viscosity, such as chrome plastisol ink, more frequent cleaning may be necessary.
Cleaning the Printing Platform and Ink Delivery System
In addition to nozzles, the printing platform and ink delivery system are also prone to accumulating ink residues. After each printing job, these areas should be promptly cleaned to prevent dried ink from becoming difficult to remove.
Dealing with Clogged Screens
If the printing screen becomes clogged (clogged screen plastisol ink), immediately stop printing and use a dedicated cleaning solution or compressed air to clear the blockage. In severe cases, a new screen may be required.
IV. Deep Cleaning and Maintenance
For long-term use, it is advisable to perform deep cleaning of the printing equipment periodically. This often involves partially disassembling the equipment to thoroughly remove hard-to-reach ink residues. Deep cleaning requires professional skills and tools, and it’s best to have it done by experts.
Furthermore, inspect and replace worn-out components such as seals and nozzles to ensure the smooth operation of the equipment.
V. Preventing Ink Clogging and Contamination
To prevent ink clogging and contamination, consider the following measures:
- Use High-Quality Ink: Opt for inks with good stability and fluidity (e.g.,

- Keep Equipment Dry: Avoid exposing the equipment to humid environments for extended periods to reduce the likelihood of ink clumping due to moisture.
Conclusion
In conclusion, effectively cleaning plastisol ink printing equipment and nozzles is crucial for ensuring print quality and equipment longevity. By selecting the right cleaning tools and chemicals, following daily cleaning procedures, performing deep cleaning and maintenance, and taking preventive measures, we can minimize the risks of ink clogging and contamination, ensuring the efficient operation of printing equipment.
