Can someone give me a primer on color postscript ? Basically: we are interested in buying a QMS Colorscript 100 printer to print 24-bit RGB images. Is this a good idea ? More specifically, how complicated will it be to write the necessary programs, to, for example, take a 24-bit raw raster image with color lookup table and output it on the QMS. Who will do the color dithering ? How long will a 512x512x3 image take to transfer ? Does anyone have a better way of producing good quality color image output for less than $10K ? Please email responses. Thanks. Cheers, Dan Ts'o 212-570-7671 Dept.

The gray scale info will be simulated using the same kind of dithering approach that a laserwriter uses to simulate gray levels. The results are certainly worth looking at, but are not photographic quality. As for speed, calculate the time it takes using your favorite communications line to transmit the image (512*512*3 bytes) and add about 20 seconds to actually print the thing. That's about how fast it will run. - Geof
