Spectrodensitometer

Standard Teraplikasi

ISO 13655 Standard: The spectrodensitometer complies with the ISO 13655 standard. This standard specifies four testing conditions, namely M0, M1, M2, and M3, which are used to accurately measure parameters such as density and overprinting rate in the printing industry. - M0 testing condition: The reflectance measured using an A - light source (with a color temperature of 2856K±100K). It was previously known as no - filter and includes ultraviolet light. - M1 testing condition: The reflectance measured using a D50 light source (previously known as daylight or D65 filter), and the measured paper whiteness is the same as the visual observation. - M2 testing condition: The reflectance measured using an A - light source without ultraviolet - ray components. It was previously known as a UV - removing filter, which excludes ultraviolet light. - M3 testing condition: The reflectance measured using a horizontally - polarized A - light source without ultraviolet - ray components. It was previously known as a polarized - light filter.
