RTP (Cold Print) Inks
Ferro’s RTP Series (Cold Print) organic inks are opaque screen process inks available in liquid paste form for single-print glass decoration.
Available in a wide range of standard colors, the SpecTrulite™ RTP series of liquid paste organic inks deliver durable and vibrant designs with superior glass adhesion.
SpecTruLite liquid paste organic inks are generally used for single-print applications, however, they can also be used along with our HTP thermoplastic inks in multi-print applications.
Greater Cost Savings
SpecTruLite™ liquid paste opaque organic inks are a ready-to-use single-component formulation requiring no dilution. They also do not require a white underlayer, which can reduce the total amount of white color necessary for decoration and yield cost savings.
RTP (Cold Print) inks work equally well on round, oval and flat glass containers. They must be cured after each print.
As these inks cure at a lower temperature than ceramic inks, less energy is used for heating. Our liquid paste organic inks can also be used on the existing printing machines and equipment already used with traditional inorganic glass enamels.
Vibrant Colors that are Environmentally Friendly
SpecTruLite™ liquid paste organic inks are environmentally friendly inks that are safe to handle and result in reduced emissions compared to 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™ liquid paste 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
