Sufficient response will be answered in summarization. > One thing you can do with grey scale is use anti-aliasing. With the proper software this could improve the effective resolution a lot without increasing the cost of the monitor. I remember reading a column by Steve Gibson in Inforworld a while back where he talked about improving the on-screen appearance on character sets greatly by using anti-aliasing with only 4 levels of grey scale. This makes me wonder whether Display Postscipt supports anti-aliasing of character sets. If it does then it could make the NeXT machine a more effective DTP machine. -- Joel Upchurch/Concurrent Computer Corp/2486 Sand Lake Rd/Orlando, FL 32809 joel@peora.ccur.com {uiucuxc,hoptoad,petsd,ucf-cs}!peora!joel (407)850-1040
