The Moisture Meter for screen printers is designed to measure the humidity level of the emulsion, playing a vital role in maintaining precise moisture levels for consistent and top-quality screen printing results. By accurately monitoring and adjusting the humidity, screen printers can achieve sharp outlines, fine details, and overall excellence in their prints.
Importance of Controlling Variables
- Controlling variables like humidity is essential for achieving consistent results in the printing process.
- Testing humidity levels is a simple yet impactful way to ensure successful screen printing by controlling variables effectively.
- Maintaining humidity levels below 30% is crucial for optimal emulsion conditions in screen printing.
Risks of Excessive Moisture
- Leaving a dry coated screen exposed to excessive moisture poses risks to screen development.
- Absorbing water from the surroundings can lead to poor screen quality, resulting in blurry outlines and reduced longevity during production runs.
- Avoiding excessive moisture is key to ensuring high-quality prints and the longevity of screens.
Reliability of Touch Test vs. Moisture Meter
- Comparing the accuracy of touch tests with a moisture meter reveals the necessity of investing in precise assessment tools.
- Relying solely on touch for screen readiness can be unreliable, highlighting the importance of using a moisture meter.
- A moisture meter eliminates guesswork and provides clear indications of screen readiness for printing.
Benefits of Using a Moisture Meter
- Using a moisture meter designed for screen printing helps avoid damage to screens with spike mesh contacts.
- Ensuring accurate measurement of moisture levels with a moisture meter leads to sharp outlines and fine details in prints.
- Consistency in screen printing is crucial, and a moisture meter plays a key role in achieving optimal results.
Cost Savings and Efficiency
- Inadequate drying or excessive moisture can lead to costly screen breakdowns during production runs.
- Investing in a moisture meter leads to long-term cost savings and efficiency gains.
- Using a moisture meter minimizes production downtime and enhances productivity in screen printing operations.
How the Moisture Meter operates


Check out this short Video

You see the two metal contact points (picture above) are flat on the moisture meter for screen printers, not pointed as you often find them in wood or masonry. This is important because you don’t want to puncture your screen.
How to measure
On the screen dried with photo emulsion, press the moister meter lightly onto the screen with its two knobs so that both contact points touch the emulsion. At the same time, press the button with the water drop and read on the scale in which range the pointer deflects. Green means ready to go, orange means you should wait a little longer and if it’s red, you should definitely let the photo emulsion dry out longer.
Conclusion
A moisture meter is essential for maintaining optimal emulsion conditions and achieving superior results in screen printing projects. It is a key tool that helps screen printers ensure consistency and precision in their work. By investing in a moisture meter and adhering to best practices, screen printers can enhance the quality of their prints and streamline their production processes effectively.
The Product I worked with and used here is the Saati Aqua Check Moisture Meter, the price of it, is above 700USD.
Unfortunately, I have not yet had the opportunity to try out such meters to know if this could work, it would definitely be much cheaper. But I don’t know if it works. But if anyone else has tried it, please leave a note in the comments, I would love to hear about your experience.
