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).
Claims4
A method of high resolution printing, comprising:
- a. processing and analyzing data to alter the final image by at least one of three methods, said methods comprising:
- i. time-delaying the image data to achieve finer vertical control over print images;
- ii. horizontally offsetting pixel images to achieve finer horizontal control over print images;
- and
- iii. using pixels of fractional sized to achieve finer control over filling in print image.
