Inkjet Film

What Is Inkjet Film?

Inkjet film is a waterproof transparency film used to create film positives for screen printing exposure. The film is designed to accept ink from inkjet printers while producing dense black images that block UV light during the exposure process.

High-quality film positives help improve stencil detail, exposure consistency, and overall print quality.

Why Waterproof Inkjet Film Matters

Waterproof inkjet films feature a specially coated surface that holds ink on the film rather than allowing it to absorb into the material. This helps produce darker blacks, sharper image edges, and more opaque film positives than standard transparency films.

Improved image density helps create better stencil definition and more consistent exposure results.

The Importance of UV-Blocking Ink

The purpose of a film positive is to prevent UV light from reaching the emulsion in image areas during exposure. If the printed image does not provide sufficient opacity, UV light can pass through the film and expose areas that should remain unexposed. This can lead to loss of detail, poor edge definition, and stencil breakdown.

For best results, waterproof inkjet film should be paired with a high-opacity UV-blocking ink designed specifically for film positive output.

InstaINK™ Film Positive Ink is formulated to produce dense, opaque blacks that effectively block UV light during exposure. When combined with quality waterproof inkjet film, InstaINK helps create sharper stencil edges, improved detail reproduction, and more consistent exposure results.

EconoJet vs InstaJet Inkjet Film

EconoJet waterproof inkjet film provides an economical solution for producing film positives while maintaining excellent image quality for most screen printing applications.

InstaJet premium waterproof inkjet film is designed for printers who require maximum image density, superior detail reproduction, and consistent results for demanding exposure applications.

Both films are available in sheets and rolls and perform best when paired with InstaINK™ Film Positive Ink.

Roll Film vs Sheet Film

Inkjet film is available in both sheets and rolls. Sheet film is commonly used for smaller artwork and standard exposure units, while roll film is often preferred for larger graphics and higher-volume production environments.

Selecting the proper format depends on your printer size, artwork requirements, and production workflow.

Choosing the Right Inkjet Film

The best inkjet film depends on your printer, artwork detail, and production requirements. Both economy and premium films can produce excellent film positives when paired with proper printer settings and a UV-blocking film positive ink.

For maximum opacity and UV blocking performance, pair your waterproof inkjet film with InstaINK™ Film Positive Ink.
