Lines: 18 I'm a veteran of Dick Rubenstein's Digital Typography course. I remember his discussion of the interaction of device physics (electrostatics) and write- white and write-black devices. How can anyone design low level hints without knowing if the the device is write-white or write-black? And is there any information in systemdict (PostScript) to know which way a laser printer is set up? Exp. Note: quoting Rebenstein here: "One striking difference among laser printers is that some write a black image on the drum during formation of the image, and others write the white part of the image. Because of the way the toner is attaracted to the resulting charged image, one image will be bolder than the other, even thought _exactly_the_same_array_of_dots_ is specified. A font designed for one printer may give dramatically different results on another..." -- Henry Troup - BNR owns but does not share my opinions | 21 years in Canada... uunet!bnrgate!hwt%bwdlh490 HWT@BNR.CA 613-765-2337 |
