Pressure-sensitive Prescale film for measuring surface contact pressure distribution, MW range: 10 to 50 MPa (100 to 500 kgf/cm²; 1450 to 7250 psi))
Fuji Prescale Film MW: Overview
Although the Prescale film was developed by Fuji Film as early as the second half of the 1970s, countless additional applications have been successfully
addressed using Prescale Film (see specific sections). Even today, several years after its introduction, new applications continue to be added to those
already known.
To better address the wide range of possible applications for Prescale, Fuji Film has developed this family of products, expanding it across various
measurement ranges (with the range further extended in recent years). This development aims to offer a product family capable of covering virtually
any application. Specifically, the Prescale MW film is suitable for all applications where contact pressures range from 10 to 50 MPa (from 100 to 500
kgf/cm²; from 1450 to 7250 psi). In manufacturing and production environments, there are countless situations that require verification of the correct
amount of applied pressure. Moreover, the ability to monitor this critical parameter helps extend the operational life of machines and their parts,
improves production quality, and, in some cases, even enhances personnel safety. Consistency and stability in the applied pressure, relative to the
various production processes utilizing it, improve the final quality of the production, as it indirectly helps control and enhance the repeatability
of the process itself.
The Prescale product range is indeed a methodology for studying, analyzing, and verifying surface contact phenomena, which can be advantageously used
without requiring specific skills or technical knowledge. The use of Prescale pressure-sensitive film is very simple, fast, intuitive, and does not require
special preparation. From the first use, the impression created with various shades of magenta will provide a clear visualization of pressure distribution,
which can be interpreted by directly comparing it with the provided colorimetric chart or through more accurate and repeatable electronic measurement tools.
Numerous studies conducted by authoritative and independent parties have confirmed the validity, accuracy, and repeatability of these results, even when
compared with other measurement methodologies using different technologies. Many production environments have effectively "normalized" numerous internal
quality checks based on the use of Prescale film.

Fuji Prescale Film MW: Technology Overview
Depending on their measurement range, Prescale films are available in two different formats: single-sheet and double-sheet. For lower measurement ranges,
Fuji Film's technology indeed requires the use of two different sheets (A and C), whereas for higher measurement ranges, the Prescale film becomes a single
sheet. The Prescale film with the MW range is available only in the double-sheet version. The double-sheet type consists of a first sheet called Film-A,
on which an extremely uniform layer of microcapsules (proprietary PSC - Particle Size Control technology) containing a coloring substance is deposited,
and a second sheet called Film-C, on which the fixative agent for the coloring substance has been applied.
When the Prescale film is subjected to surface contact stress, the dye microcapsules will rupture (in a quantity proportional to the applied
contact pressure and according to the distribution generated by the stressed areas), causing the dye to be released and immediately fixed by
the chemical reagent present on the second sheet. Thanks to Fuji Film technology, it is possible to produce films with microcapsule layers
characterized by different and optimizable rupture points during production, essentially providing a range of measurement fields while ensuring
high repeatability and predictability of the rupture point.

Fuji Prescale Film MW: Usage Instructions
It is recommended to prepare the Prescale MW films well in advance of the test to allow the films (Film-A and Film-C) to acclimatize to the environmental
conditions of temperature and humidity in which they will actually be used. Unroll an appropriate amount of film for the test to be conducted, ensuring that
it is placed on a clean, dry surface, preferably in a dimly lit area: these preparatory actions will allow the films to lie flat, simplifying the subsequent
cutting and positioning operations described in the sequence outlined below. During these operations (and those that follow), place only the glossy sides of
the films on the work surfaces (the matte sides are, in fact, those that will collectively determine the density and distribution of the recorded coloration),
to avoid any accidental contact that could expose the films before the tests.
Proceed to cut the Prescale LLW sheets to the desired dimensions using a simple pair of scissors. Since it consists of two films (Film-A and Film-C),
make sure to cut both films that make up the Prescale Film, ensuring that the dimensions you define are suitable for the area to be tested.
For the reasons mentioned earlier, handle the Prescale MW with the utmost care and delicacy. Then proceed to overlay the two films, ensuring
that the cut shapes match for both films. The films should be placed facing each other with their matte sides (glossy sides facing outward);
therefore, keep this in mind during the cutting process.
After aligning the two films with their respective opaque sides facing each other, place the resulting double layer in the area to be tested.
Apply the contact phenomenon to be studied to impress the Prescale. For details on how to reproduce the phenomenon being analyzed and the timing involved,
refer to the instruction sheet provided.
Evaluate the results of the test using the instruction sheet provided with the Prescale, which includes a colorimetric scale and reference charts.
The film will show a mapping of the detected contact areas, recording (according to the density of the developed color) the magnitude of the applied pressure,
which can be assessed visually by comparing it with the provided colorimetric chart.
THE FOLLOWING STEPS ARE OPTIONAL AS THEY REQUIRE THE USE OF ADDITIONAL ANALYSIS TOOLS THAT CAN BE PURCHASED SEPARATELY.
If more accurate and repeatable evaluations of the results obtained from Prescale are necessary, it is possible to scan the impressed films (for example, using an Epson™
Perfection scanner) to obtain electronic format images. These images can then be easily saved, stored, and archived (for potential future comparisons), but most importantly,
they can be analyzed using optional support software.
Once digital scans of the Prescale films impressed by the analyzed event have been prepared, you can use the optional FPD-8010E support software to perform further
analyses, such as evaluating colorimetric results using false colors, rendering three-dimensional profiles, calculating the average contact pressure, etc.
See package FPD-8010E for more details.
It is also worth noting the availability of the Prescale Safety Data Sheet and an initial guide to selecting measurement ranges, tailored to various application scenarios, complemented by an introduction to the FPD-8010E system:
The Prescale film with MW range has been advantageously used in the following application areas:
calibration of contact pressures between molds and dies;
pressure control between rollers and surfaces;
adjustment of contact pressures in calender rollers;
study and verification of tire footprints;
analysis of contact pressures between discs and pads in braking systems;
verification of pressures during the winding of high-performance films;
calibration of contact pressure for applicator blades distributing pastes, adhesives, and coatings;
study and analysis of pressure distribution and magnitude generated by impacts on surfaces;
medical studies and analysis (e.g., plantar pressure, orthopedics, ergonomics, etc.
