GROWinK is a regenerative printing system that merges CMYK inkjet technology with fungi and bacteria, turning prints into living, temporary media. Designed for designers, brands, and cultural institutions working with posters, textiles, and graphic communication, it offers an alternative to petroleum-based inks. Using fungal pigments and dormant bacterial spores, GROWinK eliminates toxic chemicals and activates decomposition in humid or landfill-like environments. Its innovation lies in reframing print as a life cycle where color exists briefly, then safely returns to the earth.
