01
Printing and decals
Screen printing works well for relatively simple artwork and controlled print areas. Colors are applied directly to the glass, creating a clean branded result. Multi-color artwork requires careful registration and may affect cost and tolerances.
Decals can support more detailed graphics or areas that are difficult to print directly. Buyers should confirm color references, artwork resolution, firing or curing requirements and the approved sample standard.
02
Coating, frosting and colored effects
Spray coating can create opaque, translucent, gradient or specialty color effects. Performance depends on the coating system and intended use, so discuss abrasion, moisture, heat and chemical exposure before approval.
Frosting provides a matte appearance and can be combined with printing or labels. Always approve a physical sample because glass color, wall thickness and lighting influence the final appearance.
03
Design for production, not only for a rendering
Keep critical logos away from mold seams, highly curved transitions and contact points where handling may damage decoration. Confirm printable area and tolerance using the supplier’s drawing.
For regulated products, decoration and labels must not obscure required information. FDA guidance notes that cosmetic labeling requirements may apply to both immediate and outer containers.
- Provide vector artwork and Pantone or other color references
- Define acceptable color variation
- Specify adhesion or abrasion expectations
- Approve a decorated sample before bulk production
