Screen Printing Tools to Master the Variables

My Topic, HOW TO SCREEN PRINT LIKE A PRO explain what makes the difference from a Basic to a Professional Screen Printer.

It looks like a lot of a thing to control, but this is what it is, more control you have, so better will be the outcome this every-time.

As there are things that you need to observe, by just plain trying it. There are other things that you need to measure.

screen printing tools used by professionals

And for this, we have luckily some tools to do so.

For my part, we can even get obsessed with it,  but nevertheless, the goal is to have total control, and for sure, so more you know, so more control you have.

Let’s see, what Professional Screen Printers use.

Tension Meter

A tension meter in screen printing is an essential tool used for measuring the tension of the mesh or screen. The screen’s tension is a crucial factor in screen printing as it directly influences the quality of the print.

Accurate tension ensures that the mesh rebounds back to its original state after the squeegee has passed over it during the printing process. This proper rebound ensures the ink is deposited correctly on the material being printed, resulting in a clean and sharp image.

If the tension is too low, the mesh won’t rebound correctly, causing problems like blurred images or color registration errors. On the other hand, if the tension is too high, it may cause the mesh to tear or the frame to warp. Therefore, maintaining the right tension is vital for achieving high-quality prints, and a tension meter helps to ensure this.


In screen printing, a hygrometer plays a vital role in maintaining optimal humidity levels in the print shop environment. This device measures the amount of humidity and water vapor in the atmosphere, and screen printers use it to manage and control the photo stencil and printing environment, especially by printing with water-based ink.

A print shop environment that’s too dry might cause the ink to dry too quickly, potentially blocking the screen mesh and disrupting the printing process.

Furthermore, the correct humidity level also influences the exposure time of the emulsion, so maintaining the ideal humidity (usually around 40-50%) can significantly improve the overall print quality and productivity of a screen printing operation. Thus, a hygrometer is an essential tool in any screen printing shop.

Dehumidifier and/or Air Condition

The darkroom is a climate-controlled area where you can keep the humidity below 40% for best screen development, 24 hours a day, 7 days a week.


To dry the photo emulsion on the screen, it is advisable to use a heater during the drying process. This speeds up the whole process and you also get the humidity under control, so that the emulsion gets the desired %.

But never direct the air jet directly at the screen, because the photo emulsion is very good as a dust collector and this should be avoided as much as possible.

Moisture Meter

Special moisture meter for screen printing

A moisture meter confirms a screen printer that the emulsion has the right humidity level to guarantee proper exposure.

Please make sure that the contacts are flat and not spiky. We do not want to puncture our screen when measuring.

Exposure Calculator

The Exposure Calculator is a must-have Tool.

  • Accurate Timing: The exposure calculator provides precise timing for exposing screens. This is critical because underexposure or overexposure of the screens can lead to issues in the final print, such as loss of detail or durability issues in the stencil.
  • Cost-Efficient: An exposure calculator can help reduce waste by ensuring that screens are properly exposed the first time around. This helps to save on materials and reduces the costs associated with redoing misexposed screens.
  • Consistent Results: By using an exposure calculator, screen printers can achieve consistent results every time. This is particularly important when you need to re-create a design at a later date or when you’re creating multiple screens for a multi-color design.
  • Time-Saving: Experimenting with exposure times can be a time-consuming process. An exposure calculator can help to cut down on this experimentation time, allowing screen printers to be more efficient and productive.
  • Versatility: An exposure calculator can take into account different types of emulsion, mesh counts, coating techniques, light sources, and other variables. This versatility means that a screen printer can achieve optimal results regardless of the specific details of their process.
  • Quality Control: An exposure calculator can play a crucial role in quality control. It ensures that each screen is exposed for the correct amount of time, thereby minimizing the chances of errors and defects in the finished product.

Stencil Thickness Gauge

A stencil thickness gauge, or an emulsion thickness gauge, is a valuable tool for screen printers for several reasons:

  1. Consistency: By using a stencil thickness gauge, screen printers can maintain consistent stencil or emulsion thickness across all screens. This consistency is important for achieving consistent print quality. If the thickness of the stencil varies, it can lead to differences in the amount of ink that is deposited on the substrate, which in turn affects the look and feel of the final print.
  2. Quality Control: A stencil thickness gauge can play a crucial role in quality control. It ensures that each screen meets the required specifications, thereby minimizing the chances of errors and defects in the finished product.
  3. Efficiency: Proper stencil thickness can prevent issues such as bleeding or smudging of the ink, thereby reducing the number of rejected prints and improving overall efficiency.
  4. Ink Consumption: Stencil thickness can affect the amount of ink used in printing. If the stencil is too thick, it could lead to excessive ink usage, and if it’s too thin, it could lead to inadequate coverage. By using a stencil thickness gauge, screen printers can optimize their ink usage, saving costs in the process.
  5. Experimentation: When trying new techniques or working with different materials, a stencil thickness gauge can help screen printers understand the impact of stencil thickness on the final print, enabling them to refine their technique.
  6. Professionalism: Using tools like a stencil thickness gauge demonstrates a commitment to quality and professionalism. It shows that the printer is serious about their craft and is willing to invest in tools that ensure the highest quality prints.

In summary, a stencil thickness gauge is a valuable tool that can help screen printers maintain consistency, improve quality, reduce costs, and refine their techniques. It’s a small investment that can have a big impact on the quality and profitability of a screen printing business.

Profile Meter

A profile meter, also known as a surface roughness tester or surface profiler, is used to measure the surface roughness or surface profile of a material. In the context of screen printing, here’s why a profile meter can be useful: to measure the roughness of the photo emulsion. It’s a nice tool to have if you have the pocket money for it. But if you are more low Budget and if you always do an additional face coating to your dry-coated screen, you should be fine without it.

Mesh Counter

A mesh counter, also known as a mesh count magnifier or a thread count magnifier, is an important tool for screen printers for several reasons:

  • Determining Mesh Count: The primary purpose of a mesh counter is to determine the mesh count of a screen. The mesh count refers to the number of threads per inch in the screen mesh. This is a crucial piece of information because it directly impacts the level of detail that can be achieved in a print, the amount of ink that gets deposited, and the types of inks that can be used.
  • Efficient Use of Materials: Different mesh counts require different amounts of emulsion and ink. By knowing the mesh count of their screens, screen printers can use their materials more efficiently and reduce waste.
  • Improved Communication: If a screen printer is outsourcing their screens to be made elsewhere, a mesh counter can help ensure that the screens are made to the correct specifications.
  • Quality Control: Consistency in screen mesh counts is important for maintaining print quality across different screens and different print jobs. A mesh counter allows screen printers to confirm that their screens are consistent and meet the required specifications.

In summary, a mesh counter is a critical tool for any screen printer. It enables them to select the correct screens for each job, maintain high-quality prints, use materials efficiently, and avoid potential printing issues.

Magnifying Glass and/or Digital portable Microscope

A digital portable microscope can be an extremely beneficial tool for a screen printer for several reasons:

  1. Detailed Examination: A digital portable microscope allows screen printers to closely examine the quality of their screens and prints. This can help them to spot any issues such as pinholes, misaligned fibers, or other flaws that could affect the quality of the print.
  2. Quality Control: The ability to closely examine screens and prints is crucial for maintaining high-quality work. A digital portable microscope can play a crucial role in quality control, allowing screen printers to identify and address potential issues before they become significant problems.
  3. Learning and Improvement: By allowing for a close-up view of their work, a digital portable microscope can help screen printers to better understand the effects of different techniques and materials. This can be valuable for learning and continuous improvement.
  4. Client Communication: In some cases, a screen printer might need to explain a particular issue or aspect of the work to a client. A digital portable microscope can be used to provide visual evidence to support these conversations.
  5. Precision Work: For particularly fine or detailed work, a digital portable microscope can be invaluable. It allows screen printers to check the precision and accuracy of their work in a way that wouldn’t be possible with the naked eye.
  6. Documentation: Digital portable microscopes often have the ability to capture images or videos. This can be useful for documentation purposes, allowing screen printers to keep records of their work or to track the evolution of a particular piece over time.

In summary, a digital portable microscope is a versatile tool that can help a screen printer to improve the quality and precision of their work, to learn and develop their skills, to communicate more effectively with clients, and to document their work for future reference.

Better is, to use a vacuum to remove the water and keep your screen clean.


The Thermometer is very important for the Screen Printing Shop, as it provides an indication, under what condition you are working. And to be sure, your ink stock does stay well, important for water-based inks.

Squeegee Sharpener

For a Quality Print, you will need a sharp Squeegee. The only way to maintain a sharp Squeegee is to have a Squeegee sharpener.

Pantone Capture

Identify the colors and match them.

Even slight variations in color can have a significant impact on a design’s look and feel. A Pantone color capture tool helps ensure consistency, both within a single project and across different projects.

Viscosity Meter

By measuring the viscosity of the ink, a screen printer can achieve consistent results across multiple print runs. This is especially important when working on large projects or reprints, where consistency is key.

Electronic Balance

An electronic balance, also known as a digital scale, can be very useful in a screen printing environment for a number of reasons:

  • Ink Mixing: Many screen printers mix their own inks to achieve specific colors. A digital scale allows them to precisely measure the components of each mix, ensuring consistency and reproducibility. If a specific color mix is successful, having accurate measurements allows it to be reproduced exactly in future print runs.
  • Cost Management: Knowing exactly how much ink is used for a specific print run can help screen printers estimate costs more accurately, contributing to better budgeting and pricing strategies.
  • Inventory Management: By weighing the remaining amount of ink, a printer can better manage inventory, knowing when it’s time to order more supplies.
  • Waste Minimization: By accurately measuring ink, screen printers can ensure they are only using what is necessary for each job, thus reducing waste and increasing sustainability.

Pantone Formula Guide

Pantone is a standardized color-matching system, utilized by various industries to ensure accurate color reproduction. Here’s why a screen printer needs a Pantone guide or system:

  • Color Matching: The Pantone system allows for accurate color matching. Each color in the system has a unique code that refers to a specific mix of pigments. This allows a screen printer to match colors with precision and consistency.
  • Communication: Using the Pantone system simplifies communication between the printer and the client or designer. Instead of trying to describe a color, they can just refer to the Pantone number.
  • Consistency Across Prints: Using the Pantone system can help ensure color consistency across different print runs and even across different printers. This is especially important for brands, which often need their logo and other materials to be a consistent color.
  • Professionalism: Using the Pantone system demonstrates a commitment to high-quality, professional work. This can help attract more discerning clients.

Light Booth

A light booth, also known as a color viewing booth or light box, is a crucial tool for screen printers for the following reasons:

  1. Color Accuracy: Different lighting conditions can dramatically affect how a color appears. A light booth provides a standardized environment for viewing printed materials, enabling screen printers to see the true colors of their prints. This ensures the color accuracy of the final product.
  2. Consistency: A light booth can replicate different types of lighting (such as daylight, fluorescent, incandescent, etc.), allowing screen printers to see how their prints will look under these conditions. This helps ensure the consistency of prints across various lighting conditions.
  3. Client Satisfaction: Using a light booth can help meet client expectations by ensuring that the colors of the final printed product match the colors of the design proof.
  4. Quality Control: Light booths are essential for quality control in screen printing. They allow screen printers to detect any issues or inconsistencies in the print before it is delivered to the client.
  5. Reduced Reprints: By catching color discrepancies early, light booths can reduce the need for costly reprints.
