 Re: We tried 4 color process printing today....
Postscript output devices all that a built in ability to adjust the calibration. The easies way to access the postscript function using the transfer function inside of photoshop. This same function has the ability to be embeded in the printer driver using by adding it to the printers Postscript printer description (.ppd) file.
When the film and exposure is correct, you should be able to print a graduated screen using a standard print stroke and have the resulting print look like the graduated stroke on the computer monitor.
Without the film being calibrate, the typical results is that on the light end, the smaller screen percentages get lost and on the dark side of the scale it all fills into 100% black.
