How Capillary Film Works in Screen Printing
Film Application to the Screen
Capillary film is placed onto a wet screen, where moisture draws the film evenly into the mesh openings. Once dry, the film becomes firmly bonded to the screen.
Exposure and Image Development
The screen is exposed to UV light through a positive film. Exposed areas harden, while unexposed areas wash out during rinsing, forming the stencil.
Ready-to-Print Stencil
After drying, the screen is ready for ink application with clean edges and consistent ink flow.
Key Benefits of Using Capillary Film
Consistent Emulsion Thickness
Factory-controlled thickness ensures predictable ink deposit and uniform print results across multiple screens.
High Detail and Sharp Edges
Capillary film excels at reproducing fine lines, halftones, and detailed artwork.
Reduced Setup Variability
Unlike hand-coated emulsions, capillary film minimises inconsistencies caused by operator technique.
Cleaner Screen Reclaiming
The uniform layer often makes reclaiming faster and more efficient after printing.
Capillary Film vs Liquid Emulsion
Precision and Repeatability
Capillary film provides superior consistency, making it ideal for repeat jobs and brand-critical prints.
Setup Time
While liquid emulsion is quicker to coat for high-volume setups, capillary film requires more careful handling during application.
Cost Considerations
Capillary film is typically more expensive per screen but offers time savings and reduced error rates.
Best Use Cases in Custom Apparel Printing
Capillary film is commonly used for:
- High-detail logo prints
- Fine text and line artwork
- Halftone and photographic designs
- Long-run production requiring consistent results
Australian screen printers often choose capillary film for premium apparel and retail-quality garments where precision is essential.
Fabric and Ink Compatibility
Plastisol Inks
Capillary film performs well with plastisol inks, delivering controlled ink deposit and clean prints.
Water-Based Inks
Its smooth stencil surface supports even water-based ink flow when exposure and drying are properly managed.
Fabric Types
Capillary film is suitable for printing on cotton, cotton blends, and select synthetic fabrics.
Practical Considerations When Using Capillary Film
Storage and Handling
Capillary film must be stored in a cool, dry environment to maintain sensitivity and performance.
Exposure Accuracy
Precise exposure times are critical, as capillary film is less forgiving than liquid emulsion.
Training and Experience
Proper technique is required to apply and expose capillary film successfully.
Capillary Film in the Australian Printing Environment
Australian print shops working with detailed artwork, fashion prints, or brand-sensitive designs often rely on capillary film to meet quality expectations. Its reliability supports consistent output across large runs and repeat orders.
The Role of Capillary Film in Professional Screen Printing
Capillary film plays an important role in achieving high-quality, consistent screen prints in custom apparel production. By offering superior control over stencil thickness and detail, it helps Australian garment printers deliver precise, durable prints that meet professional standards across a wide range of applications.
