Before printing silicone ink, proper surface treatment is essential.
Shoe materials like PU leather, EVA, or rubber often have low surface energy, which affects adhesion.

Tips:

• Clean oil and dust
• Use primer if necessary
• Test adhesion before mass production

Different shoe materials require different silicone ink formulations.

For example:

• High elasticity silicone for sports shoes
• Strong adhesion silicone for leather
• High-density silicone for 3D effects

Choosing the wrong ink can lead to cracking or peeling.

Printing thickness directly affects the final appearance and durability.

Recommendations:

• Use proper mesh count for silicone ink
• Control layer thickness for 3D or flat effects
• Avoid overly thick layers to prevent curing issues

Curing is one of the most critical steps in silicone screen printing.

If not properly cured:

• The print may feel sticky
• Poor wash resistance
• Reduced durability

Standard suggestion:

• 100–150°C curing temperature
• Adjust time based on thickness

Always test before bulk production.

Common tests:

• Stretching test
• Washing test
• Peeling test

This ensures the silicone print meets quality standards for footwear applications.
