% In the Photoshop Color Settings Custom Dot Gain Grayscale dialog
box there
% are 13 dot area steps.
% You create a target with those halftone dot values and print them.
% Then you measure the print.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Here's Dr. Dotgain's Postscript code for a 1x6 inch target with 13
steps plus a solid patch and a zero patch...
% Put the following code in a text file named Gray_scale.eps and open
it in Photoshop...
% Change the resolution from 72 dpi to at least 300 dpi when
prompted, just to make the labels readable.
