For printing detailed designs with silicone ink, you should use a higher mesh count, typically in the range of 160–230 mesh (63–90 threads per cm), depending on the level of detail in your design and the ink's viscosity.
Factors to Consider:
Detail in the Design:
Fine Details: Use 200–230 mesh (78–90 threads/cm) for intricate linework, small text, or detailed graphics. These mesh counts allow better control over fine details while preventing excessive ink deposit.
Moderate Details: For designs that are not overly intricate but still require accuracy, a 160–200 mesh (63–78 threads/cm) works well.
Silicone Ink Properties:
Silicone inks are thicker than plastisol or water-based inks, meaning they don't flow as easily through very fine mesh screens. To balance detail and ink flow, a mesh count around 200 is often the sweet spot.
Ink Deposit Requirements:
Higher mesh counts produce thinner ink layers, which are ideal for details.
Lower mesh counts (e.g., 110–160) are better for bold designs or when you need a thick ink deposit, such as for athletic prints with high opacity.
Fabric Type:
For stretchy or textured fabrics, you may need to slightly lower the mesh count (e.g., 160–180) to ensure the ink penetrates the fabric surface adequately.
Recommendations for Detailed Silicone Printing:
Start with a 200 mesh screen for fine detail.
Adjust up (to 230) or down (to 160) depending on the specific design, fabric, and ink flow during testing.
Additional Tips:
Thinning the Ink: If your silicone ink is too thick for higher mesh counts, use a compatible silicone ink reducer or thinner to improve flow.
Proper Off-Contact: Ensure your screen has the correct off-contact distance (around 1/16 inch) to prevent smudging and maintain sharp details.
Test Prints: Always perform test prints to fine-tune your mesh count, ink viscosity, and curing process.
By selecting the right mesh count and optimizing your setup, you can achieve sharp, detailed prints with silicone ink while maintaining its unique durability and stretchability.
