  Product Inquiry

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.
