Digital BW, The Print

Again tonight I tried Paul's curves on Kirkland paper, with the same
ill-fated results. I must have a different driver (latest), or ink
batch (Nov 04), or printer firmware (who knows), than Paul. My
comparison to QTR is here:

2005/01/roark-curves-vs-qtr-for-kirkland-paper.html

In comparing EvenTone dither with Ordered, I found Ordered dither to
be slightly (but still visibly) darker, perhaps with more contrast. I
was not able to quantify the dot pattern differences.

Looking forward to your full report, Jim.
