ABSTRACT:
A method of producing a screen for printing a heating line pattern which comprises the steps of: depositing a first photosensitive emulsion layer on a screen, masking a predetermined portion of the first photosensitive emulsion layer corresponding to a heating line pattern comprising bus bars and heating lines, exposing the first photosensitive emulsion layer except the masked portion to form the first cured emulsion layer, removing the unexposed portion of the first photosensitive emulsion layer to form the permeable portion in the first cured emulsion layer, depositing a second photosensitive emulsion layer at least on the first cured emulsion layer adjacent to the permeable portions corresponding to the bus bars, masking predetermined portions of the second photosensitive emulsion layer on the first cured emulsion layer, exposing the second photosensitive emulsion layer except the masked portions to form a second cured emulsion layer comprised of unmasked exposed portions, and removing the unexposed portion of the second photosensitive emulsion layer to leave unmasked exposed portions of the second cured emulsion layer on said first cured emulsion layer.
