Product overview

IRX-HF ink is environmentally-friendly, two pack type IR transmittable ink for glass that does not intentionally use Halogen(Chlorine Cl, Bromine Br) compounds in raw materials. It has superior finish in terms of transparency and leveling properties, compared to IR inks of GLS-HF ink series.


  • Infrared sensor part of cell phones, PCs, home appliances, etc.

Features, Function

  • Transmits infrared rays and blocks visible light.
  • No intentional use of Halogen(Chlorine Cl, Bromine Br)compounds in raw materials. (Cl ≦900ppm, Br ≦900ppm, Cl+Br ≦1500ppm)
  • Compared with IR ink of GLS-HF ink series, it is possible to create printed materials with excellent transparency and leveling.


  • Glass plate


  • Z-705 SOLVENT (slow)
  • Dilution: 5 to 10%
  • *Do not use other solvents as they may cause contamination of halogen, curing, adhesion, stencil stability, and other adverse effects.

Catalyst, Promoter mixing

  • GLS GLASS PROMOTER 0.5% (Be sure to add it, otherwise ink will not adhere)
  • Pot life: 6 hrs.
  • *The ink will not turn to gel after the pot life (6 hrs.) has expired. Due to its poor adhesion and resistance, be sure to mix only enough to use.


  • SM-40 DEFOAMER less than 1% (For anti-foam and improving leveling)

Recommended cleaner

  • Screen Cleaner L2


  • T 300 to 420 mesh


  • 160℃ 30 min
  • Overprint
    Each layer  160℃ 10 min(tack-free)
    Final layer  160℃ 30 min

Introduction of
Color Guide

  • We offer color matching products according to your transmittance rate request.
  • HF001 VICTORIA is available for adjusting density at the time of printing.
  • When using HF001 VICTORIA, be sure to measure and confirm transmittance rate before printing.


  • Due to the possibilities of contamination with halogen compounds, only designated solvents and additives can be used.
  • Please check the squeegee rubber, emulsion, materials and substrates before use, as they may contain halogen compounds.
  • Checking before production: Adhesion and resistance properties may change due to differences in substrates, processes, printing and drying conditions. Be sure to check the adhesiveness and resistance properties before mass production printing
  • Ink shelf life: 6 months from production date, unopened. (12 months for HF001 VICTORIA)


  • UN No.: Not classified in the definition
  • UN Classification: Not classified in the definition


  • Use safety gloves and eyeglasses to protect skin and eyes. If the ink comes in contact with skin, wash with soap and plenty of water (or lukewarm water) and consult with a doctor.
  • Containers should be closed tightly after use and stored in a cool and dark place.
  • SDS is available upon request. Please request a copy and read it carefully before handling the products.

How do you use IR transmittable ink (IR Transmitting Ink) ?

After printing IR transmittable ink (IR Transmitting Ink) onto transparent PC or PET substrate sheet, the ink has the special function of blocking the shorter wave-length visible rays and ultra violet rays and allows the longer wave-length infrared rays to penetrate. One example of an application that this ink is used for is the signal receiving filter of remote control devices.

What is dead front (concealed) printing applying the IR transparency function?

As mentioned above, IR transmittable inks allow control of transmittable colors, and variation in hue can be achieved by overprint with metallic inks. Therefore, various decorations are possible with “dead front (concealed) printing,” printing that cannot be seen unless illuminated by light.

Note1) Transmittance varies slightly depending on the transmitted color.
Note2) Infrared transmittance decreases by 10-20% when over printed with metallic inks. Related Links Introduction of IR Transmittable Ink and Dead front Printing

What are the meanings of X and Q used in the ink names such as IPX, INQ, FMX, etc.?

X and Q are used to designate isophorone-free inks.
