METHOD FOR OBTAINING OPTICAL INTERFERENCE EFFECTS BY MEANS OF DIGITAL INK-JET TECHNIQUE

摘要

The present invention relates to a method for obtaining optical interference effects on enamelled or non-enamelled ceramic or glass surfaces or enamelled metallic surfaces by means of the digital ink-jet technique. Said method involves applying "ink-jet effect inks" with a high refraction index on a laminar interphase with a sub-micrometric particle size with a low refraction index. The invention additionally comprises a ceramic, glass or metallic product decorated by means of said method.
