Scott is wrong. How wrong? Have you ever seen the movie, my cousin Vinny. remember when Vinny says.
Vinny Gambini: How could it take you five minutes to cook your grits when it takes the entire grit-eating world 20 minutes?
Claiming to produce a 75 degree screen in a digital world is very mush the same thing. It is simply impossible to make a 75 degree screen with a raster device as much as it is to cook grits in 5 minutes.
Raster devices are like checkered boards. The number of angles draw across the board is very limited. 75 degrees simply is not one of the option.
In a prior job, i wrote a postscript spot function which created tear drop shaped spot function along with a none linear transfer function which created a gravure cell structure for chemical etching, which was calibrated to a linear halftone curve. Is silk screening any different?
One thing which i tried early on, was to rotate the graphic, crop marks and all a negative 7 degrees. When exposed, the 7 degrees would be manually corrected at exposure, but result in a 7 degree shift in screens. So far, i have yet to see the need.
Fluid, you have any samples to share? I came to this group looking for information, not giving it. So far screen printing process color has gone much easier than expected. It seems easy enough that anyone willing to invest in good equipment can make a decent product. Am i wrong?
