How to Choose the Right Fujifilm Prescale Film for Your Application

Fujifilm Prescale pressure indicating film is one of the most versatile tools in quality control and manufacturing — but with multiple pressure ranges available, choosing the right film can feel overwhelming. This guide walks you through each grade so you can match the film to your application with confidence.

What Is Fujifilm Prescale Film?

Prescale is a thin, flexible film that reveals pressure distribution by turning red wherever pressure is applied. The intensity of the color corresponds to the amount of pressure — giving you an instant, visual map of contact stress across an entire surface. No wiring, no sensors, no calibration required.

Understanding the Pressure Ranges

Prescale films are categorized by the pressure range they detect. Here's a breakdown:

• LLLW – Ultra Super Low (0.5–2.5 MPa): Ideal for very delicate contact surfaces such as gaskets, seals, and soft material interfaces where even minimal pressure matters.
• LLW – Super Low (2.5–10 MPa): Great for applications like automotive seating, foam compression testing, and medical device contact surfaces. Shop LLW Super Low Film →
• LW – Low (10–50 MPa): A popular all-around choice for bolted joint interfaces, O-ring seating, and general assembly verification. Shop LW Low Pressure Film →
• MS – Medium (50–130 MPa): Well-suited for metal stamping, composite layup, and heat sealing applications. Shop MS Medium Pressure Film →
• HS – High (130–300 MPa): Used in high-load applications like press-fit assemblies, bearing contact, and forging. Shop HS High Pressure Film →
• HHS – Super High (300–1300 MPa): For extreme-load scenarios such as hardened steel contact, punch and die tooling, and heavy industrial presses. Shop HHS Super High Pressure Film →

Not sure where your application falls? Our Prescale Combo Pack includes LLLW, LLW, LW, and MS grades so you can test and compare before committing to a full roll.

Mono-Sheet vs. Two-Sheet Film

Some grades (like MS) are available in both mono-sheet and two-sheet formats. Two-sheet film (MW) uses a separate developer sheet and is better for applications where the film needs to be repositioned or used in tight spaces. Mono-sheet film is self-contained and easier to handle for most standard applications.

Analyzing Your Results

Once you've run your test, use the Fujifilm Prescale Mobile App to digitize and quantify your results. The app converts color density into precise pressure values, giving you data you can document and share.
