Question #2

Graded by: Pat Hanrahan's Assistant

Normally images displayed on printers require halftoning or dithering.

A. (5 points) What is halftoning and why does it work?


B. (10 points) Suppose a grey-scale image is printed on a 300 dots per inch laser printer. The operator decides to print the image using 3 different size halftone cells (each halftone cell is replicated across the page).

Which printout will look best? Describe why the other two printouts will not look as good.
