Print sharpness measurement

Purpose

Measurement of Print sharpness can be used to:

• Check if the print raggedness and blurriness is acceptable and stable over time
• Benchmark to competitors
• Monitor how new settings in the productions affect the print raggedness and blurriness
• Check if new products are better or not

Method

Quantify the print sharpness using high resolution images from a microscope or professional scanner.
The measurements are not restricted to a certain print form, instead any printed line or edge can be used for the analysis, for example part of a letter.
Two different properties are calculated:

• The raggedness which is the length of the contour of an edge compared to the perfect straight contour
• The blurriness meaning the width of the transition zone between ink and unprinted area

Image analysis is used to calculate the raggedness and the blurriness on the measured lines and shapes.

Deliveries

• The raggedness which is the length of the contour of an edge compared to the perfect straight contour
• The blurriness meaning the width of the transition zone between ink and unprinted area.
