Appendix 3: Printable Line Speeds
The following table shows the line speed at which good printing will be obtained for each raster
type and print head model at ideal pitch:
The line speeds shown above can be adjusted if printing at more than ideal pitch, i.e. double or
treble pitch (see “Appendix 1: Installation and Setting Up”).
NOTE: Print quality will be impaired if printing takes place at anything other than ideal pitch.
Ideal Pitch
Otherwise known as single pitch, this is dependent on the raster (i.e. printer type) being used.
Printers with the faster rasters have an increased pitch capacity because the overall character
height is larger. This helps to from “square” (more precise and uniform) character.
Double Pitch
Twice the ideal pitch. Print height may need to be increased to maintain character proportion.
Triple Pitch
Three times the ideal pitch. Print height may need to be increased to maintain character
proportion.
