Special Effects in Screen Printing

Special effects represent one of the most creative and rapidly growing areas of modern screen printing. This guide offers a practical framework on how to manage them professionally and reproducibly.

1. Operational Workflow

  1. Define aesthetic and technical objectives.
  2. Select special inks (metallic, glitter, phosphorescent).
  3. Prepare screens with suitable mesh and coating.
  4. Set correct deposit parameters.
  5. Monitor curing and visual performance.
  6. Document results for repeatability.

2. Technical Reference Parameters

Parameters Table
Effect Recommended Mesh Operational Notes
High density 86–109 threads/inch Requires high EOM
Glitter 81–109 threads/inch Wide mesh opening
Phosphorescent 109–196 threads/inch Requires uniform exposure
Metallic 196–229 threads/inch Dense pigments
Soft-touch 305 threads/inch Delicate surface effect

3. Common Errors and Solutions

  • Using too fine mesh with glitter leads to clogging.
  • Insufficient drying → reduced durability.
  • Incorrect curing → loss of brightness.

4. Best Practices

  • Develop process sheets for each effect.
  • Perform tests on different fabrics.
  • Integrate digital systems for parameter traceability.

5. Real Case

A fashion workshop increased margins by 30% by creating an exclusive range of eco-compatible glitter effects.

6. Advanced Checklist

  • Is the required effect defined?
  • Is the mesh adequate?
  • Is correct curing guaranteed?
  • Have tests been recorded?
  • Is the result consistent with standards?

7. Technical Glossary

  • EOM: emulsion over mesh.
  • High density: raised effect.
  • Soft-touch: velvety feel.
  • Metallic pigment: particles with brilliant reflection.
  • Luminescence: ability to emit light.

8. Conclusion

Special effects offer a strong competitive advantage, but must be handled with technical rigor to ensure quality and repeatability.
