Photographic Screen Printing

The advantage to photographic screen printing is that virtually anything you create in black and white (or black and clear) can be reproduced by this process. You must start with a film positive (one for each color if you want to print in more than one color). Refer to the How to make a Film Positive help page for more information.

There are two methods of photo screen printing. In the direct method the photo-sensitive film or liquid emulsion is applied to the screen, allowed to dry, and then exposed to the artwork (film positive) with the proper light source. There are direct liquid emulsions that work for either solvent based or water based inks or both, and the Ulano CDF direct films are available for either type of ink.

With the indirect method, the photo-sensitive film is exposed to the artwork fist, developed in developing solution or water (depending on the film) and then applied to the screen while it is still wet. The indirect method is only for solvent-based inks.
