The gloss of the print refers to the brightness of the print on the surface of the print under certain background and lighting conditions and the contrast relationship with the brightness distribution in all directions. The optical characteristics related to gloss mainly include surface reflection light and internal reflection light.
The use method of the water-based ink gloss meter in the experiment: the light source emits light through the lens 1 to reach the measured surface, the measured surface reflects the light through the lens 2 to converge to the photocell at the light bar, converts it into an electrical signal through a photoelectric converter and sends it to the processing circuit for processing, and finally displays the measurement data on the instrument.
In order to obtain the effect of the dispersion state of water-based ink on the gloss of the post-press, the black water-based ink with different dispersion states was prepared in the experiment, and the 45 ° angle gloss value of the solid color block was tested by the gravure suitability instrument.
