Lumi is a Los Angeles-based company founded by Jesse Genet and Stéphan Angoulvant producing a photographic printing process for textiles. The process is based on a photo-reactive vat dye manufactured by Lumi called Inkodye that develops its color through exposure to UV or sunlight. The process was designed to provide a simple do it yourself alternative to screen printing.

History[edit]

Jesse Genet began experimenting with different printing techniques as a teenager in 2004, attempting to print photographs on cotton t-shirts.[1] Unsatisfied with the results of screen printing and dye-sublimation she pursued her research and found what became a precursor to Inkodye, a chemical formula from the 1950s owned by a retired engineer.[1] After meeting Stéphan Angoulvant while studying at Art Center College of Design, the pair acquired the chemical formula and began modernizing it.[2]

Lumi launched a Kickstarter campaign on December 23, 2009[3] to fund R&D of the technology. The company raised $13,597 and rewarded its backers with wallets, bags and other products printed using the process. The project was an early success for the Kickstarter platform[1] and went on to win Kickstarter's Best Design Project of 2010.[4]

On June 30, 2012, Lumi launched a second Kickstarter campaign[5] with an initial fundraising target of $50,000 to commercialize its printing technology. The project was successfully funded reaching over 500% of the initial target and raising a total of $268,437. Rewards included Inkodye printing kits allowing users to create personalized photographic prints on cotton and other natural materials. The dyes are currently available in three colors (red, orange and blue) which can be mixed together and diluted with water.

Process[edit]

The process of printing with Inkodye resembles that of other alternative photographic processes though its chemistry is related to vat dyes such as indigo rather than iron or silver-based chemicals used in cyanotype or Van dyke brown which have higher toxicity.

A monochromatic digital negative is first printed on transparency film generally using an inkjet printer with black ink only. The negative is made to be the same size as the final print. Inkodye is then applied to the desired t-shirt or fabric in its undeveloped state. The negative is placed on top of the sensitized fabric and exposed to sunlight or UV light. Exposure times vary from 3 to 15 minutes depending on the desired color and intensity of light.[6] The exposure to sunlight develops the dye's color and binds it to the fabric. The final step is to wash out the unexposed dye using a washing machine and laundry detergent.[7]
