Equipment and Steps for Cleaning Screen Printing Screens
Cleaning screen printing screens is an essential part of maintaining their performance and ensuring high-quality prints. To effectively clean your screens, you will need a few pieces of equipment. Here’s a breakdown of the necessary tools and steps involved in the cleaning process:
Equipment Needed:
- Paper towels
- Scrub brush
- Pressure washer
- Optional: Spray-out tank and dip tank
Steps for Cleaning Screen Printing Screens:
- Start by removing all tape from the screen. This will help ensure a thorough cleaning.
- Next, remove any excess ink from the screen. Use a paper towel or a rag to wipe away the ink. Be careful not to spread the ink around or push it deeper into the mesh.
- If you have a screen reclaimer, follow the manufacturer’s instructions to use it. This solution helps break up the remaining ink and emulsion for easier removal.
- Lightly scrub the screen with a brush to remove any stubborn residue. Be gentle to avoid damaging the mesh.
- Wash away the emulsion and remaining ink using a pressure washer. Start from the top and work your way down to ensure a thorough clean.
- After cleaning, it’s essential to increase the mesh tension. This step helps maintain the screen’s quality and longevity.
- Finally, apply a degreaser to remove any remaining contaminants and rinse the screen with the pressure washer once more. Allow the screen to dry completely before its next use.
Following these steps and using the appropriate cleaning equipment will help keep your screen printing screens in optimal condition, ensuring longevity and producing high-quality prints every time.
Dip Tanks for Screen Reclamation
When it comes to reclaiming screens, dip tanks are an invaluable tool. These tanks, typically made from polyethylene, offer a convenient and effective solution for removing ink and reclaiming screens for reuse. By placing a used screen in a dip tank containing a screen reclaimer solution, the ink loosens and disintegrates into the solution. This process ensures that the screen is thoroughly cleaned, free from any leftover ink or residue.
Using dip tanks for screen reclamation offers several advantages. Firstly, they simplify the cleaning process by eliminating the need for excessive scrubbing or manual intervention. The screen can simply be submerged in the dip tank, allowing the solution to work its magic. Additionally, dip tanks are designed to efficiently remove ink, emulsion, and other contaminants, ensuring that the screens are thoroughly cleaned and ready for reuse.
An important consideration when using dip tanks is the choice of screen reclaimer solution. Isopropyl Alcohol is a commonly used and effective solution for breaking down ink and emulsion. It is recommended to use a screen reclaimer solution that is compatible with the types of inks and emulsions used, ensuring optimal cleaning results. It’s important to follow the manufacturer’s instructions and guidelines when using dip tanks and screen reclaimer solutions.
Benefits of Dip Tanks for Screen Reclamation
Dip tanks offer numerous benefits for screen printers, including:
- Efficiency: Dip tanks streamline the screen cleaning process, saving time and effort.
- Thorough Cleaning: Dip tanks ensure complete removal of ink and residue, leaving screens spotless.
- Cost-Effectiveness: By reclaiming screens, you can reduce the need for purchasing new screens, saving money in the long run.
- Eco-Friendly: Reclaiming screens through dip tanks promotes sustainability by reducing waste.

Reusing Screens vs. Reclaiming Screens
When it comes to screen printing, the decision to reuse screens or reclaim them depends on the specific printing job and your goals for achieving quality prints. Understanding the differences between these two options can help you make an informed decision that aligns with your needs.
If you choose to reuse screens, you can save time and resources by simply removing excess ink and ensuring the screen is clean enough to see through the emulsion. This method works well when you have similar printing jobs or when the leftover ink doesn’t affect the next print. Reusing screens is a convenient option that allows you to streamline your printing process.
On the other hand, reclaiming screens involves a more thorough cleaning process. This method is essential when you want to completely remove tape, ink, and any residue from the previous print job. By using a screen reclaimer solution, you can break up the emulsion and ensure that all ink is removed, resulting in screens that are ready for the next print.
By choosing to reclaim screens, you are investing in quality prints and preventing potential issues that may arise from leftover ink or residue. Reclaiming screens is particularly beneficial when you need to switch between different designs or colors, ensuring that previous ink doesn’t interfere with the desired print outcome. It’s an extra step that guarantees clean screens, optimal printing results, and improved longevity.
Ultimately, the choice between reusing screens or reclaiming them depends on your specific needs and priorities. Whether you opt for convenience or prioritize print quality, properly cleaning your screens with the appropriate cleaning solution is crucial for achieving the best results in your screen printing endeavors.
The Importance of Proper Screen Cleaning
Ensuring proper screen cleaning is essential for achieving high-quality prints and maximizing the lifespan of your screens. Neglecting this crucial step in the printing process can result in several issues that compromise the overall print output.
One of the main problems that arise from inadequate screen cleaning is the buildup of ink. Over time, residual ink can accumulate on the screen, leading to poor ink transfer and inconsistent prints. By following a thorough cleaning routine, you can prevent this buildup and maintain the integrity of your prints.
In addition to ink buildup, failing to clean screens properly can result in stencil damage. This occurs when leftover ink and residue interfere with the stencil’s adhesion to the screen. As a result, prints may appear blurry or distorted. By carefully removing all ink and residue, you can preserve the stencil’s integrity and ensure sharp, clear prints.
Proper screen cleaning also contributes to the longevity of your screens. By removing all potentially damaging substances, such as harsh chemicals or abrasive materials, you can prevent premature wear and tear. This extends the lifespan of your screens, reducing the need for frequent replacements and ultimately saving you time and money.
