Examples of molding products using pearl for the purpose of improved design.

4. Proposal of realizing both prevention of malfunction of electronic equipment and improvement of design

Realization of black ink and metallic ink with high resistance value:

Metallic inks and black inks containing conductive materials has the risk of static electricity flowing through the coating surface. Therefore, due to the risk of malfunction such as short-circuit of electronic circuit and radio wave interference, the use to electronic equipment was refrained.

However, by realizing nonconductive metallic ink and black ink with high resistance value, it is possible to pursue high design without fear of malfunction.


1) With high electric resistance value, it solves short circuit of electronic circuit and radio interference by energized ink layer.
2) Metallic design which was thought to be difficult for electronic equipment in the past is now made possible.
3) Black ink with high opacity can also be used for the window frame etc. of touch panel.
4) It is possible to create an ink that matches each substrate (glass, PET, PMMA, etc.).

Comparison of electronics resistance of non-conductive ink and conventional ink is as follows,

Ink Name Resistance Value of conventional ink Resistance value of non-conductive ink
Metallic ink About 104-5Ω 109Ω or more
Black ink About 105-10Ω 1012Ω or more

Application Example:

Smartphones, Touch Panel

5. Proposal of realizing both practicality and design improvement by phosphorescence function

Due to high emission luminance and long afterglow time (over 500 minutes), application range of phosphorescent ink is expanded:

Phosphorescent ink is an ink that has the function of absorbing light and emitting light. Due to its high emission brightness and long afterglow time, it exerts its power in safety and power saving applications such as safety display. Recently, applications such as utilizing the phosphorescent function for improving the design are expanding.

Ink name Color Characteristics Emission Luminance

(The part printed by Self-Restoring clear is restored, the transparency is maintained, and the non-printed part is pure white with scratches.)


8. Introduction of Sensor Ink (IR Transmittable Ink)

What is IR Transmittable ink ?:

IR transmittable ink is an ink transmitting infrared rays (IR) only and blocks other visible light and ultraviolet rays (ex. sunlight). Since printed ink layer formed by printing this ink on transparent sheet blocks those other than infrared ray, it is used for light receiving section of remote controller and infrared reception part of mobile phones.

Sensor compatible ink that can handle various wavelength light other than IR (infrared rays):

By adjusting the wavelength light to be transmitted, IR transmitted ink becomes a sensor-compatible ink that can be used for the light receiving part of various sensors.

Ink for IR sensor Application: Remote Control, IR Data transfer.

9. Proposal of new design applying IR transmittable ink

New design realized by adjusting the transmission wavelength of IR transmittable ink:

IR transmission ink can only adjust the wavelength of transmitted light while maintaining the same hue as normal ink. Since the wavelength of the transmitted light is also possible in the visible light range, a new design such as “concealing printing” in which the image appears only when irradiated with light becomes possible.

Application Example:

Automotive meter, Control panel for home appliances, Mobile Device

Although the center of the meter only looks like a rich black print.
(Woody texture like genuine parts are realized with High-Definition ink.)
