Overview
Reveal Surface Pressure with Fujifilm Prescale Film
Fujifilm Prescale is a unique pressure indicating film designed to reveal pressure distribution between contacting surfaces. This ultra-low pressure film provides a visual map of surface pressure, ideal for quality control, R&D, and process optimization.
Specifications:
- Film Type: Prescale Extreme Low LLLLW (4LW)
- Pressure Range: 7.2 - 28 PSI (0.5 - 1.97 kg/cm²)
- Dimensions: 3 ft. x 12.6 in.
- Features: Instantaneous color change, permanent record
- Applications: Heat seal planarity, roller set parallelism, impact analysis
Key Features
Characterize surface pressure between any two mating, touching, or impacting surfaces. The dimensions of this film are 3 ft. x 12.6 in.
Prescale provides a surface pressure “map” that illuminates actual pressure magnitude (in precise PSI or kg/cm^2) and distribution between your two surfaces. The pressure range of this film is 7.2 - 28 PSI (0.5 - 1.97 kg/cm²)
Prescale reveals the contact surface pressure by virtue of a color change. This color change is instantaneous (less than a millisecond) and permanent
Prescale comes on a roll, is super thin, and can easily be cut from the supplied roll with scissor or laser to your precise application requirement
The color intensity of the film is directly related to the amount of pressure applied to it
All films guaranteed to have 18 months of shelf life available.

Pros & Cons
👍 Pros
- Provides a clear surface pressure map, showing both magnitude and distribution of pressure between surfaces.
- Offers a wide pressure range of 7.2 - 28 PSI (0.5 - 1.97 kg/cm²), suitable for extreme low-pressure applications.
- Produces an instantaneous (less than a millisecond) and permanent color change, capturing transient pressure events.
- Comes on a super thin roll that can be easily cut to precise application requirements with scissors or a laser.
- The color intensity of the film directly correlates to the applied pressure, allowing for quantitative analysis.
- Guaranteed to have 18 months of shelf life available, ensuring usability over a reasonable period.
👎 Cons
- Requires visual interpretation of color intensity to determine pressure values, which may need calibration or comparison charts.
- The film has a finite shelf life of 18 months, requiring users to manage inventory to avoid expiration.
- The stated pressure range is specific to extreme low pressure, limiting its use in higher-pressure applications.
- While revealing pressure, it does not provide electronic data logging, requiring manual recording or photographic documentation.
- The dimensions of 3 ft. x 12.6 in. might not be ideal for very large or very small specific contact areas without cutting.
- The film is designed for single-use applications, which means a new piece is needed for each test.
Frequently Asked Questions
What is the primary function of Fujifilm Prescale LLLLW Pressure Indicating Film?
This film is designed to characterize surface pressure, providing a visual "map" that shows the magnitude and distribution of pressure between two mating, touching, or impacting surfaces.
What is the pressure range this specific film can measure?
The Fujifilm Extreme Low (LLLLW) Pressure Indicating Film measures pressures within the range of 7.2 - 28 PSI, which is equivalent to 0.5 - 1.97 kg/cm².
How quickly does the film react to pressure?
The film exhibits an instantaneous color change, occurring in less than a millisecond, and this change is permanent, allowing for analysis post-application.
