- Hi, I'm the author of a scientific textbook, and I did all the figures (some
- 600) in Micrografx Designer 3.0, and the publishers can't seem to print
- them properly I'm desperate -- any help at all is really appreciated.
-
- The problem is in generating color separations on Micrografx Designer 3.0?
- When Designer DRW files are used to generate 4-color (plus 1 spot)
- separations as Postscript EPS files, bit mapped patterns are lost.
- When the file is printed on typesetting equipment, what appears in the region
- that should contain the bit mapped is a pattern of large dots. The same
- problem occurs irrespective of which bit mapped pattern is being used.
- The files can be printed perfectly well on lasers in black and white or
- in color, so the problem appears to be specific to the generation of
- separations. One possibility is that the 4 screens are being
- rotated with respect to another in the region of the bit map (the angles for
- the separation are left at the default values when the postscript files are
- generated, since otherwise the rest of the drawing will not reproduce
- properly when printed). Is there any way within Designer to generate
- postscript files for 4-color separations that will allow bit maps to print
- properly, or is there any other program that could take Designer postscript
- output and manipulate it to generate effective separations?
