Are you prepared to deal with the environmental issues? (Ink Series corresponding to RoHS Directive, WEEE Directive and ELV Directive)

Products sold in EU are subject to various regulations such as RoHS, WEEE, ELV, etc. Even if a company does not export its products directly to EU, if its products are incorporated into another company’s products that will be exported to EU, the products will be regulated by these directives. Therefore any company who makes products for export must be very careful to abide by these regulations. We recognize that the environmental issue is our most important issue and are making our best effort to supply “environmentally friendly products” to our customers. We were one of the first companies to address the environmental issues and have developed environmentally friendly inks, which are free of hazardous solvents and which conform to RoHS, WEEE and ELV regulations as well as regulations expected in the future.

Ink for printing on glass (Heat Curing Organic Ink versus Calcination Inorganic Ink)

Teikoku Printing Inks has developed a screen ink for glass. It is called GLS Ink and is offered as a solution to the problems intrinsic to inorganic glass inks. When printing on glass, inorganic calcination inks have been used which involves heating the ink to 650 degrees Celsius causing it to melt onto the glass substrate. Some of these inks may contain heavy metals and are suspected to be a health hazard. The inorganic calcination inks may provide good adhesion and resistance, but few color variations are available which may limit the range of design possibilities. GLS Ink is a superior alternative from the point of view of environmental safety, versatility in design, good resistance, and ease of use. See the table below for a comparison of the advantages of the GLS Ink versus inorganic glass inks.

INQ Ink Series (Non-toxic and low odor 2 pot IMD ink)

INQ Ink series are 2 pot insert molding decoration (IMD) inks, which do not contain toxic solvents such as benzene, toluene, xylene and isophoron and which have little odor. The inks are suitable for IMD, which is widely used for nameplates, car parts and cell phones, because these inks have good adhesion when printing on PET and polycarbonate film. INQ Inks are soft and flexible, and have good heat-resistance.

MAB Ink (2 Pack Ink for Hard Coated Acrylics)

Hard coated plastic plates are widely used for the windows of electronic games, cellular phones, flat-panel displays and other electronics. In order for these windows to be scratch-resistant, they are manufactured using hard coated plastics, but it is difficult to obtain good adhesion to these hard-coated surfaces with traditional screen inks.

Technical Topics

IR Transmittable Ink (Infrared light transmittable / UV & visible light non-transmittable)

The areas printed with this ink transmit infrared light whose wavelength is longer than 850 nm, but it does not transmit visible light (400-750 nm) and ultra-violet light (190-400 nm). The major application for the use of this ink is in the manufacture of remote control devices, which are widely used for electronic appliances such as TVs and air conditioners. IR transmittable ink is designed to be used to make filters for IR-receiving windows of remote control devices.
