LA-based innovation studio Lumi has produced a light-developing permanent ink suitable for a variety of base materials, called Inkodye. The wet inks can be used on wood, papers and fabrics to print or paint designs that develop when exposed to sunlight for between 5-8 minutes. Negatives can be used to block out areas of the dye, creating complex images as shown on the brand’s Vimeo channel.
The ink is produced in three colours – red, blue and orange – which can be mixed to create a broader selection of hues. Drawing from elements of photographic image production and textile printing, Lumi provides a new tool for designers who are interested in the use of colour.
