UV LABELs™ indicate the level of UV irradiation
 in various fields by change color!

UV labels contribute to monitoring the performance of UV lights
or preserving evidence of irradiation level for quality assurance.
Just paste a UV label indicator wherever you want. “they’re easy to handle, and easy to check”.

UV labels for use during the manufacturing process

*Curing resin
Micro lenses, precision devices, touch panels,  etc.

*Drying inks
Printing, coating for automotive parts, etc.

Semiconductor manufacturing processes

Features of UV labels for disinfection practices


*Checking the radiation dose level

*Increasing the reliability of disinfection for
  hard-to-access spots.

*Checking the performance of disinfection lamps with limited service life.

With the UV indicator, you can recognize the effectiveness of the UV disinfection system and confirm whether the work has been done completely and reliably.


Standard UV label for wide wavelength 
    Type: UV-S, -H, -M, -L
    Number of elements: One
    Content: 100pcs/pkg
    RoHS compliant


Special label for UVA wavelength
    Type: LED-1, -2
    Number of elements: One
    Content: 100pcs/pkg
    RoHS compliant

*The color tones and irradiance levels shown above are based on factory tests conducted using mercury lamps. The color tone and radiation reading may differ depending upon radiation conditions.
*The LED-1 label changes from white to bright blue. There is high sensitivity around UVA ranges 365, 385, 395 and 405 nm.
For more technical information about the UV LABEL™ and UV LABEL for LED, please read the following articles. 

Usage Example


UV labels can check if the UV light is working correctly when dicing silicon wafers on a dicing tape which is broken by exposure to UV light.


UV labels are used to prevent UV ink drying and curing defects caused by insufficient UV light irradiation.

Medical fields

For the production of dental models, orthodontics, and implant treatment.

How to use

  • The UV LABEL provides only qualitative information through color changes, not quantitative information.
  • The resulting color depends on multiple factors. The same radiation intensity and wavelength do not necessarily result in the same color if other conditions differ or if a different machine is used.
  • First, obtain reference color data (A) with a specific cycle (B) and lamp (C).
  • As long as (B) and (C) are same, the result should be (A).
  • To avoid differences between lots, we recommend obtaining new reference data for each lot.


  • Size, shape and designs can be customized.
  • Sensitivity and color tone should be based on standard products.
  • Prices differ depending upon design and order quantity. Please contact our sales office for further information.


Store unused products using the black light-blocking film which comes with the product. Avoid any irradiation
before use. Interior lamps and lighting can cause color changes.
Avoid high temperature and excessive humidity. Store at room temperature.
Colors may fade if the color change is insufficient or if stored in high-temperature conditions after color change.


    • For UV-S and UV-H types, colors may fade if the color is insufficient or if stored in high-temperature conditions after color change.
    • Always store using the black light-blocking film which comes with the product. Avoid any irradiation before use.
    • Remove water, oil, rust, and dust from the surface before applying labels.
    • Contamination and uneven surfaces can result in abnormal color changes or cause labels to come off.
    • Remove the release film, apply where temperature monitoring is required, and press the surface of the label gently with finger or cloth.
    • Strong rubbing might damage the label and affect performance,  (resulting in abnormal color changes).
    • Apply labels on flat surfaces. Labels are not designed to be applied on curved or corner surfaces.

Directive of RoHS

The UV LABEL and UV LABEL for LED do not contain chemical substances prohibited by the RoHS directive.
