the image of fig1 the image is the outline of a 34 t 34 with regularly spaced substantially parallel vertical lines within the 34 t 34 once the film positive is taped to the screen the screen is exposed to ultraviolet light the photoemulsion exposed to the ultraviolet light becomes water insoluble the portion of the screen covered by the black opaque image however is not exposed to the ultraviolet light and therefore does not become water insoluble thus after exposure to ultraviolet light the photoemulsion from the portion of the screen comprising the design may be washed away with a gentle spray of cold water the partial cross sectional view of fig8 also illustrates a screen from which some photoemulsion has been washed away a gap 87 formed by two edges 89a b of hardened photoemulsion has been formed in the stencil by exposing the photoemulsion covering the screen to ultraviolet radiation with the exception of the area indicated by the gap because the stencil is of greater thickness than normally utilized ink forced through the gap is deposited in a more uniform manner having a sharper more well defined vertical edge for the design being printed the process for preparing a screen is then repeated for a second screen the black opaque image placed on the film used for the second screen is of a slightly different decorative image however this different decorative image is similar to that of the first decorative image but a portion of the regularly spaced substantially vertical lines has been removed to form.
