1.2.2 Plot Speeds
The table below lists maximum attainable plot speeds in inches per minute for continuous
unmixed full-spaced plot data. Half-spaced plot data may plot faster. Note that plot densities,
which are approximated, plot at the speed of the next higher exact density.
Density Speed (IPM)
6306 6312
60 x 48 75 150
60 x 72 50 100
120 x 72 25 50
240 x 288 3 6
Most plot data will plot at the speeds shown in the table above. Certain factors can slow down the
effective plot speed:
Plots across wide areas put a large load on the power supply. When this is detected the plot rate is
slowed momentarily to maintain proper system voltages and good print quality.
A thermal protection algorithm can slow plot rates if the hammer bank is in danger of overheating
due to an extremely heavy printing load.
Complicated graphics patterns can require extra processing which may slow the plot rate.
1.2.3 Application Benchmarks
Application processing/printing throughput is compared against other printers by means of three
benchmark tests: the standard Automotive Industry Action Group (AIAG) label, the POSTNET
label, and ECMA 132 tests.
The AIAG label benchmark consists of bar codes and block characters inside a box. It can be
printed using either the Code V or PGL graphics options, which print at the same speed. This test
prints a series of AIAG labels, two across, repeated vertically with 0.1" space between labels. The
printing time is measured and translated into the number of labels printed per hour, as in the table
below. Two variations of this test are used: Normal AIAG prints 60 DPI bar codes, Dark AIAG,
prints 120 DPI bar-codes. Speeds are listed in labels per hour.
The POSTNET label is an address label consisting of one line of POSTNET bar code and four
lines of text. The test prints a series of POSTNET labels, four across, repeated vertically with one
blank line between labels. The test is run using the Draft font at 6 LPI. Speed is listed in labels
per hour.
The ECMA 132 tests are a standard collection of "real world" applications designed to provide
realistic comparisons of printer throughput. All tests are begun with the shuttle running in order to
provide an accurate indication of long run throughput. Speed is listed in pages per hour.
