Pressure-sensitive Prescale film for measuring the distribution of surface contact pressures, HS range: 50 to 130 MPa (500 to 1300 kgf/cm²; 7250 to 18850 psi)
Fuji Prescale Film HS: Overview
Although the Prescale film was developed by Fuji Film in the late 1970s, countless additional applications have been successfully addressed using Prescale Film (see specific sections),
and even today, several years after its introduction, new applications continue to be added to those already known.
To better meet the variety of possible uses for Prescale, Fuji Film has developed this family of products, categorizing them into different measurement
ranges (which have been further expanded in recent years) to offer a product family capable of covering practically any application. Specifically, the
Prescale HS film can be used for all applications where contact pressures range from 50 to 130 MPa (from 500 to 1300 kgf/cm²; from 7250 to 18850 psi).
In the manufacturing and production sectors, there are numerous situations that require verification of the correct pressure application. Additionally,
the ability to control this important parameter can extend the operational life of machines and their parts, improve production quality levels, and in some
cases, even enhance personnel safety. The consistency and stability of the applied pressure value, in conjunction with the various production processes that
use it, therefore increase the final quality of production, as it indirectly allows for the control and improvement of process repeatability.
The Prescale product range is indeed a methodology for study, analysis, and verification, advantageously usable in the context of surface contact phenomena
without requiring specific skills or particular technical knowledge for its use. The use of Prescale pressure-sensitive film is very simple, fast, intuitive,
and does not require specific preparation; on the contrary, from its 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 colorimetric reference chart provided or through more accurate
and repeatable electronic measurement tools. Numerous studies conducted by authoritative and external parties have confirmed the validity, accuracy,
and repeatability of these results, even when compared to other survey methodologies characterized by different technologies. Indeed, many production
realities have "normalized" numerous internal quality checks based on the use of Prescale film.

Fuji Prescale Film HS: 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 technology requires the use of two different sheets (A and C), while for higher measurement ranges, the Prescale sheet becomes single.
The Prescale film with an HS range is available only in the single-sheet version (mono sheets type). The single-sheet type consists of a single sheet, 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 stress, the dye microcapsules break (in quantities proportional to the applied contact pressure and
distributed according to the actually stressed areas), causing the dye to be released, which is immediately fixed by the chemical reagent layer on the same
sheet.
Thanks to Fuji Film technology, it is possible to produce films with microcapsule layers characterized by different and optimizable breaking points during
production, effectively determining the availability of various measurement ranges while ensuring high repeatability and predictability of the breaking point.

Fuji Prescale Film HS: Usage Instructions
It is recommended to prepare the Prescale HS film well in advance of the test to allow it to adjust to the ambient temperature and humidity conditions in which
it will be used. Unroll an adequate amount of film for the test to be conducted, ensuring that it is placed on a clean, dry, and preferably dimly lit surface.
These preparatory actions will allow the film to flatten out, simplifying the subsequent cutting and positioning operations described in the steps below.
During these operations (and those that follow), only place the glossy side of the film on work surfaces (the matte side is the one that determines the density
and distribution of the recorded color), to avoid any accidental contact that might affect the film before testing.
Proceed to cut the Prescale HS film to the desired dimensions using a simple pair of scissors. For situations where the experience may involve contact with
surfaces that are not perfectly clean or are wetted with fluids that could contaminate the test, you can use the provided uncoated PET roll as a second
protective sheet.
For the reasons previously mentioned, handle the Prescale HS with utmost care and delicacy. If it is necessary to use the protective PET film roll,
overlay both sheets ensuring that the cut shapes match for both sheets (Prescale sheet and PET sheet), making sure that the matte side of the Prescale
film is protected by the PET sheet.
After protecting the matte (treated) side of the Prescale (where applicable) with the second 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 being analyzed and the timing, refer to the instruction sheet provided.
Evaluate the results of the test using the instruction sheet provided with the Prescale, which includes a color scale and reference graphs. The film will
display a map of the contact areas, recording the magnitude of the applied pressure according to the density of the developed color. This can be assessed
visually by comparing it with the provided color scale.
THE FOLLOWING STEPS ARE OPTIONAL AS THEY REQUIRE THE USE OF ADDITIONAL ANALYSIS TOOLS THAT ARE AVAILABLE FOR SEPARATE PURCHASE.
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 HS film has been advantageously used in various application scenarios, including:
calibration of contact pressures between molds and dies;
monitoring of contact pressures between rollers and surfaces;
calibration of contact pressures in calender rollers;
study and verification of tire footprints;
study and verification of contact pressures between brake discs and pads;
verification of pressures developed during the winding of high-performance films;
calibration of contact pressure for paste, adhesive, and coating distribution spatulas;
study and analysis of pressure distribution and magnitude generated by impacts on surfaces;
study and analysis in medical fields (e.g., plantar pressure, orthopedics, ergonomics, etc.).
