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)
60 x 48 225
60 x 72 150
120 x 72 75
240 x 288 9.3
Most plot data will plot at the speeds shown in the table above. Certain factors can slow down
the effective plot speed:
•
Plots using a high percentage of the available dot positions across successive dot rows.
This puts a large current load on the power supply, which can lead to decreased power
supply output voltage and result in poorly printed or missing dots. The plot rate is
slowed momentarily to maintain proper output voltage.
•
Thermal protect algorithm can slow plot rates.
•
Complicated graphics patterns. These require extra processing which may slow the plot
rate.
