An indirect photographic stencil method involves six steps:

1. Exposure


2. Development


3. Washing


4. Application of stencil to the screen


5. Drying


6. Removal of the base material

Direct process:- It uses a wet
emulsion that is coated directly on
a screen. The emulsion is exposed
through a transparent positive to
harden the non-image areas. The
images area washed away with a
warm water spray. When the
emulsion is dry the stencil is ready
to print.

Five steps in preparing the direct
photographic stencil are :

1. Preparation of a sensitized
   emulsion


2. Application of the emulsion
   to the screen


3. Drying the emulsion


4. Exposure


5. Development

Direct/Indirect process:- This
process combines the indirect
and the direct photographic
process. An unsensitised film
material is placed under the
stencil side of the screen on a flat
table. The stencil emulsion is
stored in two parts, a liquid
emulsion and a sensitiser. When
the two are mixed, and coated on
the screen, they become light
sensitive and coat through the
