Abstract
Higher quality printing is difficult in implementation in spatial light modulator printers. The two major problems are accomplishing gray scale within the line time constraints, and eliminating staircasing artifacts within the images printed (81). It can be improved by using an alternate way of resetting cells on the spatial light modulator when data is being loaded onto the cells, timing delay (86), horizontal offset (84), and differently sized pixels (80, 82).
Claims5
A spatial light modulator array with and optically active level and an electrically active level comprising:
- a. spatial light modulator cells of a standard size centered about an x-y grid;
- b. spatial light modulator cells of fractions of the standard size centered about an x-y grid;
- c. spatial light modulator cells of fractions of the standard size horizontally offset from said cells centered about said x-y grid;
- and
- d. spatial light modulator cells of standard size horizontally offset from said cells centered about said x-y grid.
