There are basically 4 different ways to use these photo systems.
The Dichromate system, painted on a screen, hardens the gelatin imagewise using UV or daylight for exposure and is developed by a hot water rinse which removes gelatin where exposure did not take place. The remaining image can be used as-is, or it can be inked and used as a resist to allow the inked image to pass through the screen to a reciever. That accounts for two possible methods.
A silver halide emulsion can be used the same way, coating a screen and when exposed will yield an image on the substrate or screen in this case. But, since silver halide does not harden gelatin unless you use a tanning developer, if you wash with hot water, the image is lost. Therefore you can either harden the gelatin beforehand and then retain the entire image, or you can use a tanning developer to harden the gelatin imagewise to retain only the developed image.
With the first way here, you cannot pass ink through and it will not act as a resist, only a substrate for the entire image. With the second way, you get a resist with pores created imagewise just as with the dichromate system. All of these methods yield fine images, the differences being exposure time and light type and processing method.
We used to make 3 or 4 color decals using these methods and printing onto transferrable blank paper decal sheets. We also made multicolor t-shirts this way. That was so long ago, it was back when there was no digital at all! We kept a bolt of cheap fine silk in the shop and several types of cloth as well for achieving the different textures that customers wanted. This used to be a service of some photofinishers back then.
