TS ISO 9959-2

TS ISO 9959-2 is the part of the drawing-test series for numerically controlled drafting equipment that focuses on monochrome raster plotters. It defines a drawing test used to evaluate the quality of graphic output, and it does so for plotters based on raster image technology regardless of machine type.

What monochrome raster plotters are

In general technical terms, a raster plotter forms an image through a scan-line or dot-matrix logic rather than by purely vector plotting. The monochrome aspect means the output is concerned with single-tone graphic production rather than colour separation. That distinction matters when assessing line formation, edge definition, text legibility, and the consistency of fine details in plotted output.

What this part covers in practical terms

• Applies the drawing test to monochrome raster plotters.
• Focuses on evaluating the quality of graphic output.
• Uses an assessment approach independent of machine type.
• Targets a specific device class within numerically controlled draughting machines.

In broader engineering practice, standards of this kind help make output quality comparable across different machines by using a common test framework. For drafting equipment, performance depends not only on motion accuracy but also on continuity of lines, absence of image loss, and the consistency of detail reproduction on the finished output. TS ISO 9959-2 concentrates that evaluation approach on plotters that produce black-and-white or other single-tone raster output.
