How to use

Just cut and insert the film to the surface you need to measure

  • Cut Prescale or Presheet to the size you need

  • Insert Prescale between the surfaces you need to measure and apply the pressure

    *when using two-sheet type, be sure the matte side of the two films will be put together

  • Take off and check the color density visually

How it works

  • Two-sheet type (5LW～MW) Composed of two kinds of films: A-film and C-film

    • A-film: Base material (PET base) coated with a color-forming material (microcapsules)
    • C-film: Base material (PET base) coated with a color-developing material

    ‎

    The coated sides of each film (color-forming and color-developing) must face each other. These are the sides with the matte finish. When pressure is applied, the microcapsules are broken and the color-forming material transfers to the color-developing material and reacts, thereby generating a red color.

  • Two-sheet type (5LW～MW) Measurement is possible with a single sheet of film.

    • A color-developing material and color-forming material (microcapsules) are coated, one above the other, on a single base material (PET base).

    ‎

    When pressure is applied, the microcapsules are broken and the color-developping material absorbs the color-forming material and reacts, thereby generating a red color.

Type of Prescale

There are 9 types of Prescale and 6 types of Presheet according to the pressure range.

Please select the appropriate range.
