methods and definitions in QuarkXpress
colour definitions should be created with great care. In a process
colour job. box Spot Color should not be checked. In spot
colour jobs the box should be checked, regardless of which is the
colour model for defining the colour.
mm trimming edges should be provided in the document. Type 3,
TrueType, Multiple Masters and system fonts must not be
used. You should also avoid using old type styles, published
before the year -91, as their kerning values differ greatly from
those of current fonts.
colour of negative elements should be defined as paper-coloured,
as 0% of one of the spot colours may not print correctly due to
different overprinting, masking and trapping values. Also
hairlines should be avoided; as rule one should not use lines
thinner than 0.5 points.
the print driver we recommend Apple LaserWriter 8.5.1 or
later, and the recommended print and file format is PostScript
