Effect of Input Precision on Line Micro Quality Measurement
Line quality micro-measurement is of important content of objective measurement,contributing to reproduction quality assessment of digital printed character and line metrics.Transforming physical presswork to digital image is not only the first but also a key procedure in micro quality measurement.In this study,effect of input resolution was verified in order to determine the precision requirement in micro quality survey.A series of experiments were carried out to measure same inkjet samples,which were scanned with a normal flatbed in three resolution sets.The effect on assessment accuracy of resolution condition was analyzed by pair-wise comparison method.Results show that normal flatbed is precise enough for micro line quality measurement.But 600DPI identified in ISO13660 standard is too low to serve in this survey.1200DPI can work well enough and extra-high resolution version will not respond to improve the measurement precision obviously in inkjet line attribute evaluation.
