①Technical Overview | Product Specifications
Retroreflection is a method of reflection that differs from ordinary reflection in that it is optically devised so that light is reflected directly back to the light source no matter from what direction it hits.
Retroreflective
Since it reflects the light that hits it straight back toward the light source, it appears to glow brightly when viewed by the driver.
Diffuse reflection
General light reflection. The light that hits the surface is diffused in different directions by the unevenness of the surface.

Flash PRINT is a patented product developed by SOKEN that can switch between two types of data using the above retroreflective sheets and printed materials, using an arithmetic data processing method that does not require addition.
About an arithmetic data processing method that does not require addition.
Printing technology with a special arrangement that is completed by inkjet.
How Flash Printing Works
This is a printing technology that allows you to see two different designs on one medium: a normal design in non-transparent ink printed on a retroreflective sheet, and a design in translucent ink that retroreflects when exposed to light.
About Color and Light
The retroreflective sees "light".
How retroreflection works
Ink specifications and weather resistance
MIMAKI - Genuine eco-solvent ink CMYKW
Weather resistance
Because of exposure to the outdoors, multiple conditions such as light, rain, wind, and the compatibility between the material and our inks It varies greatly. SS21/ES3/Eco-HS1/HS inks are irradiated with a xenon arc weatherometer at 180W/m² for 1560 hours. In the case of SS21/ES3/Eco-HS1/HS inks, we have confirmed that no significant fading occurs when the inks are irradiated with a xenon arc weatherometer for 1560 hours at 180W/m² and sprayed for 18 minutes during 120 minutes of irradiation.
②Notes on installation and use
Retroreflecting to the angle of incidence
Retroreflects in the same direction as the angle of incidence of light. It is not visible when the light is not irradiated or from an angle different from that of the irradiated light.
Cautions for the environment
In a typical bright environment, there is always an irradiated light. If your eyes are on the same line as the irradiated light, you will see the hidden reflected light. This is an unavoidable phenomenon due to technical characteristics.
The difference in visibility between flash photography in bright and dark environments
The results of the same output will vary depending on the environment. It cannot be reproduced outdoors in daylight.
The changing effect will be degraded under sunlight or in an environment that is too bright.

③About Triggers
Types of triggers to change the design of FLASH PRINT
| Trigger (1) |
| Flash photography only |
| Trigger (2) |
| Just set the headlamp. |
| Trigger (3) |
| Just look into the ring light. |
