5.1.7.2.13 LIGHTNESSADJ
The setting of this variable specifies the relative print lightness desired for multibit grayscale and RGB
color vector and raster data. Range: {-10 - +10}. Default: 0. The default value specifies a nominal
print lightness. Increasingly negative values proportionately reduce the lightness of (darkens) the
print, while increasingly positive values proportionately increase the lightness of (lightens) the print.
In the print tone adjustment process, the lightness adjustment is applied after the contrast
(CONTRASTADJ) adjustment. This setting is not applicable to PostScript plots.
The lightness adjustment affects the mid-tone values proportionately more than shadow or highlight
tone values. Technically, lightness adjustment differs from brightness adjustment, which adjusts all
tone values equally. Tone values rising above the maximum possible tone value or falling below the
minimum possible tone value would be clipped.
5.1.7.2.14 LINESCALEMODE
This parameter specifies whether or not to scale pen widths when a user defined scaling parameter is
defined. When set to ON, pen widths will scale according to the scale setting. When OFF, pen widths
will remain constant regardless of scaling percentage. The default is OFF.
5.1.7.2.15 MARGINBOTTOM/ MARGINLEFT/ MARGINRIGHT/ MARGINTOP
These parameters specify the printable area of a physical sheet of paper. Each of the variables
describes the distance from the specified edge of the physical page inward which may not be printed
upon. Images may be clipped to maintain this restriction. When calculations for auto size detection,
autorotation, label/raster stamp placement, or autoscaling occur, they utilize the printable area of the
page as defined by the physical paper size and the value of these variables.
Left and right correspond to low X values and high X values respectively in the coordinate system of the
physical page. In sheet paper sizes, the X axis is always the long edge of the paper. As described in
PAGEROTATE, the image may be rotated to preserve this definition (occurs when the page is printed
long edge first). With roll size papers, the X axis is always the feed direction of the paper.
The image’s offset which is specified with the JUSTIFYX and JUSTIFYY variables is measured from
the origin of the paper’s printable area. This point is specifically determined by MARGINLEFT (for the
X coordinate) and MARGINBOTTOM (for the Y coordinate). An example is shown below which
demonstrates margins and justification acting together to place an image on the page. Notice that the
image is clipped to the printable area defined by the MARGINxx variables.
The MARGINxxx variables can take on values ranging from 0 to 100 inches. The default value is 0.196
inches or 5mm for all variables. Note that due to numeric precision limitations within the printer, the
value 0.196 may be represented by a number which is close but not exact. Typically, the actual value is
0.19580078125. This value may vary as a function of the printer’s numeric capability precision.
