“27th FINETECH JAPAN” is the General Technology exhibition event that brings together the development and manufacturing technology on electronic display, organic electronics (organic EL, solid-state illumination, organic solar cells), and IoT equipment.
In this exhibition, we introduced our latest printing and ink technology by mainly focusing on High Definition Ink (High Quality and High Definition Screen Ink) we announced in July 2016.
Period: April 5 - 7,2017
Venue: Tokyo Big Sight

IR Transmittable Ink is the ink transmitting infrared ray (IR) only and blocking other visible light or ultraviolet ray (e.g. 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.
For example, using IR Transmittable Ink for IR receiving section of enables seamless design (with no borderline), as shown below.
IR Transmittable Ink is the ink applicable to sensor which can be used for receiving section of various sensors by adjusting wavelength light transmitted.
|Ink applicable to sensor (IR Transmittable Ink)||
Application: Remote controller, IR data transmission.
|WHITE IR Transmittable Ink||
IR transmittance of white color which was hard to realize can be realized in combination with TORAY PICASUSR125-QP4A.
|Ink for human detection sensor||
Application: Sensor people or obstacles in surroundings. IR transmitter and receiver are as 1 set.
|Ink for eyespot authentication sensor||
Application: Illuminate specific lump to the face and sense light reflected from eyes.
|Ink for camera sensor||
Application: camera focusing.
|Ink for environmental thermal sensor||
Application: Sensor detecting heat in surroundings.
|Ink applicable to sensor for environmental light-dark (ALS)||
Application: Sensing environmental light-dark and adjust electricity in surroundings and screen light-dark.
Normally, when illustration image and photo image are printed by screen printing, colors are multilayer printed tailored to the image hue. Therefore, more number of colors increase the number of stencil and printing process, and consequently increases cost.
However, High Resolution color separation ink can reproduce the image with the similarly high resolution in 4 colors and reduce the number of stencil and process, which enables printing illustration image and photo image with lower cost.
High Resolution image printing
- Dyne value of printed ink layer is over 42, which realizes stable printed ink layer.
- Therefore, the ink is excellent in post-processing property for using bonding and double sided tape.
- It enables drying at lower temperature (120°C) compared to that of conventional ink for glass (150°C).
- It demonstrates excellent Solvent resistance to MEK, acetone, etc.
- It enables sharp printing on the edge face by adjusting fluidity and thixotropic property.

The causes of transmittance defect occurring in Smoke print and IR transmittance printing are the following 4 factors.
1) Particle of pigment used
2) Leveling of printed ink layer
3) High thickness of printed ink layer
4) Change of ink viscosity
MIX-HF and TOC-HF inks with high transparency solves the above factors and realizes high-quality transmittance printing.
Transmittance rate and haze value of each ink are as follows.
|Ink name||Transmittance rate||Haze value|

At the time of printing Metallic and Pearl materials, ink viscosity change and ink dripping on stencil from squeegee may change density and orientation of Metallic and Pearl materials and cause unevenness in printed ink layer.
However, High Definition Ink maintains excellent physical property value even after containing metallic and pearl pigment material, which enables printing without unevenness.

- Substrate: Polycarbonate, Acrylic
- The ink provides high resistance to chemicals such as sunscreen cream, lactic acid, etc.
- It enables 300％ elongation in forming.
- 2 pack type Clear.
Pre-curing: Heat drying at 80℃ for 60 minutes
Forming: vacuum forming, Super-pneumatic forming
After-curing: Accumulated light energy: 250～300mＪ/cm2, peak intensity: 3 50mW/cm2
The ink realizes beautiful expression and design with high resolution.Printing fine line of about 100µm hair with 100µm～116µm accuracy.
High Definition Ink enables simultaneous printing of solid pattern, thin line, and gradation, which enables significant cost reduction by reducing the number of stencil and man-hour.
Saw edge below 10µm realizes beautiful straight line and true circle without concavo-convex.
High Definition Ink realizes both productivity improvement and reduction of defective rate. It enables continuous printing of 1500 sheets with 100µm～116µm of fine printing.
High Definition Ink enables high-speed printing of 800～1500 sheets/hour by cylinder press even in 100µm～116µm of fine printing.
It enables reprinting even after covering ink on stencil and leaving for 1 hour. Operation property significantly improves such as reduction of time waste while interruption of printing operation.
High Definition Ink enables reduction of the number of cleaning stencil up to one fifth of that of conventional ink.
Operating Hours 9:00 - 17:30(except Sat, Sun & Holidays)
