Choosing the Right Ink and Mesh: A Beginner's Cheat Sheet

Screen printing is a creative yet technical process, and mastering it requires understanding the right combination of materials to get the best results. One of the key decisions you'll face as a screen printer is choosing the appropriate ink and mesh. The ink type determines the texture, opacity, and finish of your print, while the mesh affects the amount of ink transferred to your substrate and the level of detail in your design. The right combination of both is essential for achieving high‑quality prints.

In this guide, we'll walk you through the basics of choosing the right ink and mesh for your screen printing projects. Whether you're just getting started or looking to refine your skills, this cheat sheet will help you understand the essentials and make more informed decisions in your printing process.

Understanding Screen Mesh

The mesh is the fabric that holds the stencil or design and controls the amount of ink that passes through. It plays a critical role in the quality of your prints, as it dictates both the level of detail and the amount of ink deposited on the surface. Mesh count is typically measured in threads per inch (TPI), and the right mesh count depends on the type of design you want to print.

Low Mesh Count (25--80)

• Characteristics : Large holes, thicker threads
• Pros :
  • Allows heavy ink deposits, making it ideal for dark fabrics or bold, solid designs.
  • Good for printing large images, logos, or text with little fine detail.
  • Suitable for specialty inks like puff ink, glitter, or high‑opacity inks.
• Cons :
  • Not suitable for fine detail work, as large holes can cause ink bleeding and loss of clarity.
  • Prints may have softer, less defined edges.

Best Uses : Bold designs, printing on dark fabrics, or using thick inks.

Medium Mesh Count (100--160)

• Characteristics : Balanced hole size
• Pros :
  • Versatile and works well for a variety of designs, including moderate details and solid color prints.
  • Ideal for standard textile printing on both light and dark fabrics.
• Cons :
  • May not achieve the finest detail required for very intricate designs.
  • Ink deposit is more controlled but may be insufficient for certain specialty inks.

Best Uses : General‑purpose prints on various fabric types, solid color prints, and designs with moderate detail.

High Mesh Count (160--355+)

• Characteristics : Smaller holes, thinner threads
• Pros :
  • Perfect for fine lines, intricate details, and high‑precision work like photo prints or small text.
  • Provides crisp, sharp lines and cleaner edges.
  • Ideal for light‑colored fabrics or materials that don't require heavy ink deposit.
• Cons :
  • Limited ink flow, which may be problematic for designs that require thick ink deposits or specialty inks.
  • Slower print speeds due to the smaller holes and thinner threads.

Best Uses : Detailed work, fine art prints, photo‑realistic designs, and printing on light‑colored fabrics.

Types of Ink and Their Applications

Choosing the right ink is just as important as selecting the correct mesh. Different inks have varying characteristics, and each works best with specific mesh counts, substrates, and design types. Here's an overview of the most common types of inks used in screen printing:

Plastisol Ink

• Characteristics : Thick, opaque ink with a rubber‑like texture.
• Best For : Dark‑colored fabrics, high‑opacity prints.
• Pros :
  • Highly opaque and vibrant on dark fabrics.
  • Durable and long‑lasting once cured.
  • Easy to work with for beginners.
• Cons :
  • Requires heat to cure properly.
  • Doesn't dry on its own; the printed design must be heated.
  • May feel heavier on fabric compared to other ink types.

Mesh Count : Use a low to medium mesh count (80--160) for best results.

Water‑Based Ink

• Characteristics : Water‑based, thinner ink that dries through evaporation.
• Best For : Light fabrics, eco‑friendly printing.
• Pros :
  • Softer feel on fabric, ideal for lightweight designs.
  • Dries naturally without the need for heat (although heat curing is still recommended for durability).
  • Environmentally friendly, with low emissions and waste.
• Cons :
  • Less opacity on dark fabrics, may need to apply a white underbase.
  • Requires more precise mesh selection to avoid over‑inking or insufficient coverage.

Mesh Count : Typically used with higher mesh counts (160--305) for fine details and thinner ink deposits.

Discharge Ink

• Characteristics : Water‑based ink that removes the color from fabric and replaces it with the desired color.
• Best For : Printing on dark fabrics without using a white underbase.
• Pros :
  • Produces a soft, vintage feel on dark fabrics.
  • The fabric remains soft and breathable, as no thick layers of ink are deposited.
• Cons :
  • Requires heat to activate and discharge the dye from the fabric.
  • Limited color options and works best on natural fibers.

Mesh Count : High mesh counts (160--305) are ideal to ensure a smooth, even print.

Solvent‑Based Ink

• Characteristics : Ink that uses a solvent to dissolve the pigment and create a smooth, durable print.
• Best For : Printing on non‑textile materials like plastic, glass, and metal.
• Pros :
  • Extremely durable and resistant to wear and tear.
  • Works on a wide range of substrates beyond just fabrics.
• Cons :
  • Requires specialized equipment and ventilation due to toxic fumes.
  • Less eco‑friendly compared to other ink types.

Mesh Count : Low to medium mesh count (80--160) works best for solvent‑based inks, depending on the material being printed.

UV Ink

• Characteristics : Ink that dries instantly under UV light.
• Best For : High‑speed production, detailed designs, and non‑textile surfaces.
• Pros :
  • Cures instantly under UV light, making it ideal for high‑speed printing.
  • Provides excellent durability and color retention.
• Cons :
  • Requires a UV curing system, which can be expensive.
  • May not work well with all materials, especially fabrics.

Mesh Count : Medium to high mesh count (110--230) for accurate and detailed prints.

Combining Ink and Mesh for the Best Results

The relationship between ink and mesh is a balancing act. If your mesh count is too low for the ink type, the result may be over‑saturated prints, smudges, or lack of detail. On the other hand, using a mesh count that is too high for a thick ink like Plastisol may cause the ink to deposit insufficiently, leading to a weak print.

Here are a few guidelines to help you match the right mesh count with your ink choice:

• For Heavy Inks (Plastisol, Puff Ink):

  • Use a low to medium mesh count (80--160) for the best ink deposit and opacity. These inks require larger holes to pass through and deposit thick layers of ink.

• For Thin Inks (Water‑Based, Discharge Ink):

  • Use a medium to high mesh count (160--305) to control the ink flow and ensure fine details without over‑inking.

• For Specialty Inks (Glitter, Metallic, Foil):

  • Low mesh count is often best for these specialty inks because they need more ink to create the desired effect.

• For Fine Detail and Precision:

  • Use a high mesh count (230--305) with inks that do not require heavy deposits, such as water‑based or UV inks, to achieve sharp, crisp prints.

Conclusion

Choosing the right mesh and ink for screen printing may seem overwhelming at first, but once you understand the basic characteristics of each, it becomes a lot easier to select the best materials for your project. By carefully considering your design, fabric type, and ink requirements, you can make more informed choices and produce high‑quality prints every time.

Remember, experimentation is key to mastering screen printing. Don't be afraid to test different combinations of ink and mesh until you find the perfect setup for your needs. Whether you're printing t‑shirts, posters, or specialty items, understanding how mesh and ink work together will take your prints to the next level.
