The improvement in printing offered

by the stochastic square dot

is comparable to the difference

between AM radio and FM radio.

FM

Over each square inch an average

of 40,000 randomly placed square

dots are printed side by side using

the wet on wet printing process to

smoothly blend continuous tones.

This allows double the resolution

to be printed on 240 - 260 mesh

without the fuzzy interference of

half tone screens. No static at all.

As opposed to the varying size dots

of a half tone screen, all the dots are

equal size. If one dot washes out, then

they all will. This eliminates the problems

associated with the smallest dots in

halftone screens that fall prey to

the fixed resolution of any given mesh.

No more dots that won't wash out, or

dots that get plugged up in production.

* While half tone dots work well for offset printing, they present many unique problems when used for screen printing.

Instead of the 150 line screens used in glossy magazines, screen printers instead must work in the 45 to 65 line range.

This leaves the half tone dots clearly visible, giving the final product a machine made appearance, and in the case of garment printers, a sandpaper feel to plastisol ink.

In addition to these drawbacks, screen printers must rotate the screen angles to avoid the dreaded Moiré patterns. Images also often fall prey to dot gain.

Screen printers also face enormous problems when printing in four color process.

The process inks for offset printing differ from those used in screen printing, and since all graphic software is calibrated for offset printing, it can be very difficult to reproduce images accurately.

Rendering fine type can also be a nightmare for screen printers.

SPS 2000 avoids these problems by printing all type elements in sharp postscript.
