Overview
Key Features
Characterize surface pressure between any two mating, touching, or impacting surfaces. Roll length and width are 1 ft x 12.6 in (2 m x 310 mm)
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 for this film is 0.87 - 7.3 PSI (0.06 - 0.51 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 visual pressure map showing both magnitude and distribution across the entire contact area.
- Color change is instantaneous and permanent, allowing detailed post-analysis without time constraints.
- Ultra-thin film conforms to surfaces and can be cut to any shape for precise application fit.
- Covers the ultra extreme low pressure range of 0.87–7.3 PSI for sensitive contact analysis.
- Guaranteed 18-month shelf life ensures reliability when stored for future use.
👎 Cons
- Roll dimensions of 1 ft x 12.6 in may be insufficient for large-surface applications without purchasing multiple rolls.
- Single-use film cannot be reset or reused once pressure has been applied.
- Requires a separate Prescale analysis tool or color reference chart to convert color intensity to precise PSI values.
- Sensitive to environmental factors such as humidity and temperature, which can affect accuracy if not stored properly.
Frequently Asked Questions
What pressure range does the LLLLLW (5LW) Prescale film measure?
This film measures surface pressure in the ultra extreme low range of 0.87 to 7.3 PSI (0.06 to 0.51 kg/cm²).
How does Prescale film indicate pressure?
The film changes color instantly—in less than a millisecond—when pressure is applied. The color intensity corresponds directly to the amount of pressure, and the change is permanent for later analysis.
What are the dimensions of the roll?
The roll measures 1 foot in length by 12.6 inches in width (2 meters x 310 mm).
Can the film be cut to fit specific applications?
Yes, Prescale is super thin and can easily be cut from the roll with scissors or a laser to match your exact application requirements.
What is the shelf life of this film?
