Why larger Measuring Aperture counts - Color Measurement in Digital Printing
The technical datasheets and specifications of every spectrophotometer, among other technical details, mention the measuring aperture. But why does this matter? It is because, generally said, a larger measuring aperture gives more accurate results and higher repeatability. The measuring aperture defines the area the measuring device “sees” and captures the color values from. As bigger this area, as more information will be captured. This especially in large format, flatbed and industrial printing, including textile printing is of upmost importance. When measuring different kind of media, low resolution prints or UV printing, a bigger measuring area is requested.
