Bar-Type Ink Applicator

The rod-type ink applicator is a metal cylindrical rod that evenly transfers ink onto the substrate surface through rolling. It utilizes the contact between the rod body and the substrate to form a uniform ink layer, and is used in the printing industry to test ink opacity, color concentration, and printability. It is commonly employed in laboratory proofing and quality control processes.
Selection
When selecting, consider the roughness of the substrate to match the rod diameter—use fine rods for smooth surfaces and coarse rods for rough surfaces. Choose the winding wire specifications based on standard thickness requirements, and determine the rod material according to the type of experiment. The viscosity of the ink influences the choice of rod surface treatment; stainless steel is used for routine testing, while chrome-plated rods are employed for corrosive inks.
