That's the theory. In practice, however, we have varying degrees of success in achieving exactly what we want. Properly implemented, the linearization process brings some relief, but it still leaves some problem areas, as well. Time and again, printers who make a stencil that prints a sharp dot discover that they simply can't use those screens to print accurate process color. They find their prints suffering from the effects of putting four passes of UV ink down in succession.
PITS can sabotage the best efforts at controlling the screen-printing process.
But we have other tricks at our disposal. Lacking a preventive measure for problems resulting from PITS, we have become chemists at the press. We doctor our inks with clear base to move our density down or we add toners to bring density up to adjust for color deficiencies. Unfortunately, large changes in color density have little impact on the overall image. We manipulate our print order.
