HTP (Hot Melt) Inks
Ferro’s HTP (Hot Melt) organic inks are opaque screen process inks available in solid thermoplastic form for multi-print and over-print container glass decoration. Available in a wide range of standard colors, the SpecTruLite™ line of hot melt organic inks deliver durable and vibrant designs with superior glass adhesion.
Ferro’s SpecTruLite™ HTP Series of hot melt organic thermoplastic inks offer decorators and designers a wide range of opaque standard colors that covers the Pantone spectrum. We also offer other ink options, including CMYK-equivalent inks, special effect inks, metallic effects inks and frosts, and many existing commercial brand color matches.
Greater Cost Savings
Our hot melt organic inks are a ready-to-use, single-component formulation designed for multi-print glass decoration and do not require a white underlayer, which can reduce the total amount of white color necessary for decoration and yield cost savings. As these inks cure at a lower temperature than ceramic inks, less energy is used for heating. They can also be used on the existing printing machines and equipment already used with traditional inorganic glass enamels.
SpecTruLite™ hot melt organic inks dry immediately after printing, allowing the next print to be instantly applied when using a high-speed multi-color decoration machine.
Vibrant Colors that are Environmentally Friendly
Ferro's organic inks are environmentally friendly inks that are safe to handle and result in reduced emissions compared with traditional ceramic inks.
The organic formulation is ideal for post-consumer recycling as the contaminant-free inks can be eliminated when the glass is melted.
Ferro’s SpecTruLite™ HTP Series organic inks are heavy metal-free and comply with the following regulations:
- Packaging and Packaging Waste Directive 2004/12/EC
- CONEG Legislation
- TSCA
- California Proposition 65
