[Print quality]
Setting Values Description
[Print quality] [Brightness] (default
0)
When your prints are too dark or too light,
changing the brightness can correct this prob-
lem.
-1 to -3 creates darker prints.
+1 to +3 creates lighter prints.
[Contrast] (default 0) When the difference between light and dark
areas of a print is not big enough, you can
change the contrast to correct this problem.
Example: When a blue text is displayed ras-
tered, you can increase the contrast to make
the text more black and sharper.
[Advanced settings] The advanced settings are intended for special
print jobs, such as printing bar codes or print-
ing a colour image on a B/W printer.
[Fattening] (default
[Off])
The fattening function can increase the reada-
bility of texts with small fonts (< 6 points, 2.12
mm (6/72 inch)).
However, when you print special data such as
bar codes, fattening can make bar codes diffi-
cult to read. Therefore, you can turn the fatten-
ing function off when you print such special
data.
[Minimum line width]
(default [On])
The minimum line width function is required
to keep thin lines visible. The lines in PS/PDF
jobs always keep a minimum width of 0.04
mm (1/600 inch).
However, when you print special data such as
CAD drawings, smaller lines may be required.
Therefore, you can turn the minimum line
width function off. Then even thinner lines will
be printed.
[RIP resolution] (de-
fault [600x2400] dpi)
The RIP resolution can improve the readability
of fine details. When you print very thin, slan-
ted lines, for example in Chinese characters,
1200x1200 gives the best result. 600x2400 is
best suited for mainly horizontal and vertical
objects.
