Although I have not used Icefields, I have known about it for years. It was around back in the '90s when I owned an imagesetter. This is a very specialized application that produces a frequency modulated halftone (a random halftone). Basically, it is a RIP. Most RIPS for imagesetters (a machine that writes to film to make halftone negatives for offset litho or contact photo printing) produce amplitude modulated halftone screens. This is a real problem if you are trying to print a catalog with fabric samples because the regular pattern of the AM halftone screen combines with the regular pattern of the fabric (assuming you have enough resolution to resolve the fabric pattern) and the result is an awful MOIRÉ. This is a French term for an interference pattern. It is a THIRD pattern that is synthesized from the overlapping of two other patterns. Since the FM screen is random (actually, pseudo random) it does not combine with the fabric pattern to create a moiré. This is the value of a program like Icefields. If you think photographing fabrics is a rare situation then consider that interference patterns (moiré) are also a problem when reproducing to print brick walls or anything with a regular pattern. I used to love blowing away my students by taking two sheets of AM (amplitude modulated) imagesetter film and superimposing them over a light table. When you rotate one film against the other, the resulting moiré is nothing short of psychedellic! Hope this helps. I had to write it because I hate one star reviewers who don't understand the reason for a software app.
