10.1 Glossary

Color Fill – Term within the awards and engraving industry used to describe the variety of techniques
used to add color or contrast to engraving.
DPI – Dots Per Inch or Pixels Per Inch. The resolution of an image as defined by the amount of
dots/pixels included in an inch. The DPI setting of 1000, will include tell the machine to include 1000
laser firings within an inch.
Driver – A software program that allows the computer to communicate with its components and
peripherals: printers, scanners, monitors, etc.
Firmware – Programming permanently set into a computer's ROM chips. This information is burned
into the computer chips and can only be changed by replacing the chips, or in the case of EEROM, by
special procedure.
Parallel Cable – The cable connection between the computer and another device (usually the printer).
This allows the computer to send several bits of data simultaneously.
Parallel Port – An outlet on your computer or electronic device that allows the computer and device
to be connected and share information simultaneously. Another common name for the parallel port is
the LPT port.
PPI – Pulses Per Inch. PPI determines the gross amount of laser pulses there will be per linear inch.
PPI is exclusively for the vector setting. A PPI setting of 500 results in the laser firing every .002" (500
times per inch). If the standard lens is producing a vector laser focal point of .007", then higher PPI
settings will result in deeper, overlapping laser pulses. PPI settings lower than 150 will result in the
individual laser pulses being spread far apart, so they will not touch each other. Low PPI settings are
a good example of perforate paper.
Serial Port – A connection that allows a computer to send data to a peripheral device one bit at a time.
Usually a COM port that meets the RS232C specification.
Vector – The process of cutting an image by using single horizontal, vertical and curved lines. For
example: when cutting out the outline of a square, the vector setting will make the laser use a thin
single line to follow the outline of the shape.
