What is Infrared Transmittable Ink

IR Transmittable Ink (IR Transmitting Ink) has the special characteristics which allow IR (Infrared ray) to penetrate through the ink, but it will block the visible light and ultra violet ray (Sun light and etc.)

As for the designated wavelength, transmittance rate can be adjusted by different formation of printed ink layer on the transparent sheet.

Since the ink layer will block light rays other than the Infrared radiation, this ink is commonly used for signal light receiving window of remote controller and infrared ray receiving part of the mobile phone.

- Reaction Mechanism -

1) Outgoing near-infrared ray (900-1100nm) will penetrate through the filter (printed area by Infrared Transmittable Ink (IR Transmitting Ink)).

(It will prevent malfunction of device from fluorescent lamp and visible light by blocking the ultraviolet and visible light.)

2) Infrared ray, which has passed through the filter, will be received by the sensor.

3) Received infrared ray will be changed to electric signal, then amplified to activate the switch by phototube of sensor.

1. Pigment base ink

Generally, Infrared Transmittable Ink (IR Transmitting Ink) is known to use dye compound, but this type of ink does not have strong resistance in certain areas and it has a weak point of dyeing the squeegee and the stencil. Therefore we would like to recommend pigment base IR Transmittable Ink.

2. Hue

IR Transmittable Ink has a special characteristic of blocking Ultra violet and Visible light and it has a function of infrared ray to penetrate. Also in order to conceal the inner structure of filter from outside, the color of ink surface will be blackish color.

There is a limitation of hue adjustment due to functionality of the ink, however transmitting color can be controlled. (Transmittance rate varies by different colors) In addition, we have metallic inks for additional hue variation of the ink, but the transmittance rate of infrared ray will be 10 to 20% lower than standard IR transmittable inks.

3. Halogen Free

We have been developing Halogen Free type of IR Transmittable Ink and does not intentionally use compounds of Chlorine (Cl) and Bromine (Br) in raw materials. Halogen free means Cl < 900 ppm, Br < 900 ppm, and Cl + Br < 1500 ppm. Currently, we have IPX-HF, MRX-HF, and GLS-HF Ink Series for Halogen Free.

4. Compatible with various types of substrate materials

We have various types of ink series. If you have any questions regarding substrate materials and inks, please feel free to contact us.

if you use infrared ink to make marked cards, the cards mark is invisible, need to ues luminous ink glasses to check it.
