Colour Filters

Hide your messages and awards so only your customers can see them with Grifoll’s colour filters

A fun way to involve the consumer. Using a color as a filter you will be able to discover winning images, messages or codes in your promotions.

Characteristics of color filters

Grifoll’s technology allows images or texts to be encoded so that they are only visible if a color filter is applied to them. In addition, Grifoll produces magic glasses or magnifying glasses that allow viewing the encrypted content, being able to create integrated design promotions.
