Speedball Diazo Photo Emulsion Kit

You’ve got your design, now it’s time to create your screen! At Speedball, we want to take the guesswork and frustration out of your creative process and have a suite of products to do just that--no matter what screen printing technique is your preferred method.


The photo emulsion method of screen printing offers unlimited creative potential by allowing artists to create fine line drawings, computer generated images, hand and commercial lettering and half-tone positives with excellent results. Speedball’s Diazo Photo Emulsion & Sensitizer offer professional-grade results and remove the need for expensive equipment and darkrooms. (For use with polyester screen fabrics) Speedball’s Diazo Photo Emulsion & Sensitizer may be used with any water-soluble or solvent-based ink and can be easily and only removed with Speedball’s Photo Emulsion Remover.


Speedball’s Diazo Photo Emulsion is a 2-step process where the photo emulsion needs to be “activated.” To activate the emulsion, sensitizer must be added. The sensitizer is a very thick oil and needs water to create the right consistency for adding it to the photo emulsion. The big advantage of Speedball’s’ Diazo Photo Emulsion is there is no need for a light safe environment. Simply working under normal light will keep the emulsion from premature exposure.
