Glossary of Terms (continued)
Term Definition
Flash Memory A microchip based non-volatile memory device that holds its data
when power is removed. This allows for field reprogramming of
the Printer commands, such as Printer firmware upgrades, without
the necessity of changing chips.
Font A character set similar in style and form. Fonts can be graphical
or mathematical constructs, represented by a series of dots or an
assembly of curves and lines.
FPGA (Field
Programmable Gate
Array)
A microchip with configurable logic circuits installed that is
programmed to act as the Printer's central processor.
Full bleed Printing that covers the entire card surface.
Gamma The degree of contrast of an image or the display of a monitor
determined by the slope of a characteristic curve relating optical
density to relative log exposure.
Glossy / Matte A smooth polished surface in comparison to a rougher matte
surface. Fargo matte cards have a surface index (Ra) of
approximately 65 microinches while glossy have a Ra = 3.
Glossy PVC A card made of PVC with a smooth polished surface (Surface
roughness of approximately 0 - 10 micro-inches). This is required
for direct to card dye-sublimation printing.
Graphical Device
Interface (GDI)
A Windows standard for protocol between Drivers and
applications and the Windows interface. An application uses a
Driver to rasterize the data in the format necessary for the Printer
but also for the Windows interface to execute the print
commands.
Gray Scale A graduation through the various brightness levels from white to
black.
Halftoning A process in monochrome printing that simulates continuous tone
by using changes to the distribution of single dots. Increasing the
number of dots in a given area increases the darkness even
though the individual dots stay the same size.
