Printing ink scraper Rod

The printing ink drawdown bar is a metal cylindrical rod with wires of varying diameters wound around its surface to create gaps. It is used to apply ink onto a substrate, forming a uniform wet film for testing properties such as ink opacity and color intensity. It is commonly employed in print quality control and ink development processes.
Selection
Select the wire gap specification based on the viscosity of the ink to be tested, opting for a larger gap for high viscosity. Consider the surface characteristics of the substrate; rough surfaces are suitable for larger gaps. Match the precision of the drawdown rod according to the test standard requirements, with stainless steel being commonly used in laboratories. Pay attention to the wear of the drawdown rod and replace it promptly when necessary.

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.
