The role of a reflection densitometer in controlling printing ink concentration.
The reflection densitometer measures the light reflectance of the ink layer and converts it into a density value, thereby objectively reflecting the thickness and concentration of the ink layer. In printing, it is used to monitor solid density, ensuring stable ink supply, replacing subjective judgment, and enabling data-driven control.
Density Determination: Selection Strategy between Pycnometer Method and Densimeter Method
This article introduces two methods for measuring the density of substances: the pycnometer method and the densimeter method. The pycnometer method calculates density by measuring the mass of a sample of fixed volume. It is suitable for measuring liquids, powders, and small granular solids, offering high precision but slower operation, and requires temperature control.
