Optically controlled black ink product lineup
This website uses automated machine translation. Please note that translations may not be fully accurate and may differ from the original Japanese text.
We introduce three types of black inks that excel in optical control.
We offer a lineup of low-reflectance black inks achieving reflectivity below 1%, infrared transmission black inks that combine high blocking in the visible light range and high transmittance in the near-infrared range, and light-blocking black inks that achieve high light-blocking performance in thin films.

Low-Reflection Black Ink SS MATT911
This black ink achieves a reflectivity of less than 1%.
Enables more precise control of ghost flare.
By blocking light from the lens and suppressing stray light, it contributes to improving image quality.
