replace more expensive film negatives. Vellum is used in screen
printing environments, such as in T-shirt printing. See also Myriad.
Volatile Parameters
Printer or controller parameters which only last during the current
power cycle of the printer. For example, the PostScript parameter
jobname specifies the name of the current printing job being
processed.
WPD File
Windows Printer Description file. A special file providing printer-
specific information which is needed by Windows applications so
that the applications work smoothly with a XANTÉ printer or
controller.
X•ACT (XANTÉ Accurate Calibration Technology)
XANTÉ technology that compensates for print engine variations so
you can print more precise horizontal and vertical dimensions. This
is critical when printing color separations and other jobs where
pinpoint accuracy is essential for registration. See also Registration.
X-HEIGHT
The height of a lower case letter without an ascender or descender in
a typeface.
X-Screening
XANTÉ’s method of using a dispersed dot screen, also referred to as
stochastic screening. It varies the distance between individual ink
dots in a seemingly random pattern. Areas with greater numbers of
dots appear darker while those with fewer dots appear lighter.
XON/XOFF
A software-controlled protocol which controls the flow of data in
serial communication. See also DTR/DSR.
