Pressure-sensitive Prescale film for measuring the distribution of surface contact pressures, MS range: from 10 to 50 MPa (from 100 to 500 kgf/cm²; from 1450 to 7250 psi).
Fuji Prescale Film MS: Overview
Although the Prescale film was developed by Fuji Film in the second half of the 1970s, countless additional applications have been successfully addressed
using Prescale Film (see specific sections). Even today, many years after its introduction, new applications continue to be added to the already known ones.
To better address the wide range of possible applications for Prescale, Fuji Film has developed this product line, offering different measurement ranges
(which have been further expanded in recent years) to provide a product family capable of covering almost any application. In particular, the Prescale MS
film can be used for all applications where contact pressures are between 10 and 50 MPa (100 to 500 kgf/cm²; 1450 to 7250 psi). The manufacturing and
production situations requiring verification of the correct amount of applied pressure are numerous. Furthermore, 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 cases, even enhances
ersonnel safety. The consistency and stability of the applied pressure, in conjunction with the various production processes that use it, therefore
increase the final quality of production by indirectly enabling the control and improvement of process repeatability.
The Prescale product range is indeed a methodology for study, analysis, and verification that is advantageously used in surface contact phenomena,
without requiring specific skills or technical knowledge for its use. The Prescale pressure-sensitive film is very simple, quick, and intuitive to use
and does not require specific preparation. From its very first use, the image impressed with various shades of magenta red will provide a clear
visualization of the pressure distribution, which can be interpreted by direct comparison with the provided colorimetric reference chart or by more accurate
and repeatable electronic measuring means. Numerous studies conducted by authoritative and external parties have confirmed the validity, accuracy, and
repeatability of these results, even when compared with other measurement methodologies using different technologies. Indeed, many manufacturing
environments have effectively "normalized" numerous internal quality checks based on the use of Prescale film.

Fuji Prescale Film MS: 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 requires the use of two different sheets (A and C), while for higher measurement ranges, the
Prescale sheet is single. The Prescale film with the MS range is available only in the single-sheet version (mono sheets type). The single-sheet type
consists of a single sheet that contains both a layer of fixing agent for the dye released from the microcapsules and a very homogeneous layer of
microcapsules (proprietary PSC - Particle Size Control technology).
When the Prescale film is subjected to surface contact stress, the dye microcapsules will break (in quantities proportional to the applied contact
pressure and according to the distribution created by the actually stressed areas), causing the dye to be released, which will be immediately fixed
by the chemical reagent layer present on the same sheet. Thanks to Fuji Film technology, it is possible to produce films with microcapsule layers
characterized by different and optimizable break points during production, essentially determining the availability of various measurement ranges
while ensuring high repeatability and predictability of the break point.

Fuji Prescale Film MS: Usage Instructions
It is recommended to prepare the Prescale MS film well in advance of the test, to allow the film to acclimate to the environmental conditions
of temperature and humidity in which it will be used. Unroll an adequate amount of film for the test to be conducted, ensuring that it rests on a clean,
dry surface, preferably dimly lit: these preparatory actions will allow the film to settle, simplifying the subsequent cutting and positioning operations
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 might impress the film
before the tests.
Proceed to cut the Prescale MS film sheet to the desired dimensions using a simple pair of scissors.
For cases where experience might involve contact with surfaces that are not perfectly clean or are wetted with fluids that could contaminate the test, you can use the provided PET roll (untreated) as
a second protective sheet.
For the reasons previously mentioned, handle the Prescale MS with the utmost care and delicacy. When it is necessary to use the PET protective
film roll, overlay both sheets ensuring that the cut shape matches 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 (if required) 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 in order to impress the Prescale. For details on how and when to reproduce the phenomenon under analysis,
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 the mapping of the contact areas recorded, indicating (based on the developed color density) the amount of applied pressure,
which can be assessed visually by comparing it with the provided colorimetric table.
THE FOLLOWING STEPS ARE OPTIONAL AS THEY REQUIRE 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 MS film has been advantageously used in various application scenarios such as the following:
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.).
