Does Inkodye work in cloudy weather? How about UV lights?

Inkodye reacts primarily to bright UV and full-spectrum light, such as sunlight. There are many things that can affect how much sunlight your print is receiving: time of day, seasons, altitude, latitude, cloud cover, even placing glass or acrylic over your print will dampen the sun's rays. For best results we recommend printing around midday on a sunny day. If you're printing in overcast weather, double your exposure time, or wait until the color appears fully saturated. If it is too cloudy, Inkodye might not be able to fully react. 

You can also invest in a UV exposure unit such as the ones used for screen-printing. Follow our step-by-step guide for how to print Inkodye with UV light.
