Pressure-sensitive Prescale film for measuring the distribution of surface contact pressures, range HHS: from 130 to 300 MPa (from 1300 to 3000 kgf/cm²; from 18850 to 43500 psi)
Fuji Prescale Film HHS: Overview
Although the Prescale film was developed by Fuji Film in the late 1970s, countless additional applications have been successfully addressed by the Prescale Film (see relevant sections).
Even today, many years after its introduction, new applications continue to be added to those already known.
To better respond to the multitude of possible applications for Prescale, Fuji Film has developed this product family, organizing it into different
measurement ranges (which have been further expanded in recent years) to offer a product family capable of covering virtually any application.
Specifically, the Prescale HHS film can be used for all applications where contact pressures range between 130 and 300 MPa (from 1300 to 3000 kgf/cm²;
from 18850 to 43500 psi). The situations in the manufacturing and production sectors that require verification of the correct pressure applied are numerous.
Additionally, the ability to control this important parameter helps extend the operational life of machines and their parts, improves the quality levels of
production, and in some circumstances, increases personnel safety. The consistency and stability of the applied pressure value, within the various production
processes that use it, therefore increase the final quality of production, as it indirectly allows for controlling and improving the repeatability of the process
itself.
The Prescale product range is essentially a methodology for study, analysis, and verification, which can be advantageously used in the context
of surface contact phenomena without requiring specific skills or technical knowledge. The use of the Prescale pressure-sensitive film is very simple,
fast, intuitive, and does not require specific preparation. From its very first use, the image impressed with the different levels of magenta red will
offer a clear visualization of the pressure distribution. This can be interpreted by direct comparison with the provided reference colorimetric chart or
through more accurate and repeatable electronic measuring tools. Numerous studies conducted by authoritative and external parties have confirmed the validity,
accuracy, and repeatability of these results, even when compared with other survey methodologies characterized by different technologies.
Many production facilities have indeed "standardized" numerous internal quality checks based on the use of Prescale film.

Fuji Prescale Film HHS: Technology Overview
Depending on their measurement range, Prescale films are available in two different formats, namely single and double sheet:
for lower measurement ranges, Fuji Film technology requires the use of two different sheets (A and C), while for higher measurement ranges,
the Prescale film is a single sheet. The Prescale film with HHS range is only available in a single sheet type (mono sheets type).
This single sheet type consists of a single film, on which both a layer of fixative agent for the dye released by the breaking of microcapsules
and an extremely homogeneous layer of microcapsules (proprietary PSC - Particle Size Control technology) are deposited.
When the Prescale film is subjected to surface contact pressure, the dye microcapsules break (in quantities proportional to the
amount of contact pressure applied and according to the distribution from the zones actually stressed), causing the dye to be released
and immediately fixed by the layer of chemical reagent present on the same sheet. Thanks to Fuji Film technology, it is possible to
produce films with layers of microcapsules characterized by different and optimizable breaking points during production, essentially
providing various measurement ranges while ensuring high repeatability and predictability of the breaking point.
If you have any doubts, further useful information can be obtained by consulting the FAQ Prescale.

Fuji Prescale Film HHS: Usage Instructions
It is advisable to prepare the HHS Prescale film well in advance of the test to allow the film to adapt to the ambient temperature and humidity
conditions in which it will be used. Unroll a sufficient length of film for the test, ensuring that it is placed on a clean, dry surface, preferably
in a low-light environment. These preparatory actions will allow the film to lie flat, making the subsequent cutting and positioning operations easier,
as described in the sequence below.
During these operations (and those that follow), place only the glossy side of the film on the work surfaces (the matte side is the one that will
determine the density and distribution of the recorded coloration) to avoid any accidental contact that could expose the film before the tests.
Proceed by cutting the Prescale HHS film to the desired dimensions using a simple pair of scissors.
In cases where experience might involve contact with surfaces that are not perfectly clean or are damp with fluids that could
contaminate the test, you can use the provided roll of untreated PET film as an additional protective layer.
For the reasons previously mentioned, handle the Prescale HHS film with the utmost care and delicacy.
When it is necessary to use the protective PET film roll, overlay both sheets ensuring that the cut shape matches for both the Prescale
film and the PET sheet. Make sure that the matte side of the Prescale film is covered by the PET sheet.
After protecting the matte (treated) side of the Prescale film (if required) with the additional PET sheet, place the single sheet (or
the double layer obtained with the PET sheet) in the area to be tested. Then apply the contact phenomenon to be studied to impress the Prescale.
For details on how to reproduce the phenomenon and timing, refer to the instructions provided with the product.
Evaluate the test results using the instruction sheet provided with the Prescale, which includes a colorimetric scale and reference charts.
The film will display the mapping of the contact zones, recording (based on the density of the developed color) the magnitude of the applied pressure.
This can be visually assessed by comparing it with the colorimetric chart included in the kit.
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 the HHS range has been effectively used in applications such as:
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.
