Jacquard Photo Emulsion & Diazo Sensitizer - Jacquard s Photo Emulsion (used with the accompanying Diazo Sensitizer) is a light-sensitive emulsion used to burn stencils directly into a silk screen for photo imaging. It is the staple emulsion for making screens with photos, lettering, logos or detailed images. Jacquard s Photo Emulsion is super durable, allowing for superior detail, and is easily reclaimed from the screen using diluted bleach.
