Thanks for your help, Jim. I would have to agree with your predictions. I tried printing out sample arrays, and under a microscope the grid is entirely sporatic and random. Two last questions (and a bonus one):
1) Would a higher dpi printer alleviate this problem?
2) Would a different style of printer help (inkjet, etc)?
Bonus) What did you mean by pursuing a photographic path? I have no experience with this.
