Lumi ink is a light sensitive clothing dye which acts as if you’re in the dark room. Grab a simple photograph, a t-shirt or a canvas bag, some lumi ink and a sheet of acetate then you’re good to go.
Step 1: Convert your photo into a Negative using Photoshop or Paint.
Step 2: Print your negative photo onto a piece of Acetate.
Step 3: Place the image in the desired place on your fabric.
Step 4: Using the roll on attachment, apply Lumi ink to fabric.
Step 5: Lay it outside in the sunshine for 10-20 minutes.
Step 6: It should look more like this when its dry. Bring it inside and wash it.
Step 7: VOILA! Only the bits that were exposed will end up sticking to the material and you’ll end up with an awesome personalised garment.
