pattern unsuitable for use in laying out patterns in the etchant resist the prior art use of the silicone layer 40 was used to protect the top surfaces of the opaque emulsions from accidental having to support any foreign object ironically in contrast to the prior art that attempted to avoid placement of foreign objects on top of the opaque projections the present invention deliberately places spacers on top of the opaque projections and on the compressible emulsion layer adjacent the opaque projections in order to compare the evacuation paths formed by the present invention and the prior art reference should be made to fig5 and fig6 fig5 shows a prior art emulsion master pattern on a photo printing plate 10 located on emulsion layer 12 are the opaque master patterns 16 that represent the interior region of the mask and the opaque master patterns 15 that represents the continuous strip line located on top of the emulsion layer is a coating of silicone 40 that is used to prevent dirt particles from clinging to the photo printing plate during use and reuse of the photo printing plates during the printing process the layer of etchant resist on the metal web would be in contact with top surfaces 42 43 and 44 note that in the prior art without the island spacers such as shown in tiala the evacuation paths from the center of the mask to the outside.
