There are two ways of doing this. The first (through the Epson print
dialogue) ... I forgot ;-) The second, better way is by adjusting
the gradation curve in the "Image" menu. Basically, you want the
curve somewhat flat at the top (i.e. in the shadows). In printing
terms this will result in depositing less ink for the blackest areas.
Just drag the top of the curve down until the blacks print crisply
without blocking and smear -- its a matter of experimenting. To find
the right curve I used a grayscale image. Please contact me offline
for a copy of the grayscale.
