claude72,
Nice examples. I've often thought of making something like that to use as a sort of tutorial for designers who use Photoshop for everything. When you save as a PDF from Photoshop, you will see that the fonts are embedded, however the text is still not rendered in the same way as it would be if set in Indesign, Illustrator, etc. Instead of the text being directly rendered with a fill color, it is used as a clipping mask to reveal parts of an image. If you place black text over a regular image, Photoshop will create an image in a rectangular area that extends past the edges of the text, and all of the pixels will be black. It then uses text in a font as a clipping mask to cut out the image so that only the text is visible. This is interpreted differently than normal text by the trapping process, and I believe it will not be trapped by the Adobe trapping engine no matter the settings. Obviously this is still much better than having it completely rasterized.
You said that screen dots cannot be cut to follow the ideal path when the type is rasterized. I assume you mean that the screen dots cannot be cut within the domain of a pixel of the raster image, since they are cut on the edges of them.
