Information

Thixotropy

At a certain temperature, after stirring or applying mechanical external force, the fluidity of Wood-grain Paper Digital Printing Ink products will be improved and the viscosity will decrease; after standing still, the fluidity will become poor and the viscosity will increase. This property is called Thixotropy of Wood-grain Paper Digital Printing Ink products. During the printing process, if the thixotropy of Wood-grain Paper Digital Printing Ink products is poor, there will be printing failures such as poor inking, uneven ink transfer, and severe dot expansion. In order to prevent the above failures, it is necessary to stir the Wood-grain Paper Digital Printing Ink products in the ink fountain with an ink shovel or install a Wood-grain Paper Digital Printing Ink products agitator in the ink fountain to stir the Wood-grain Paper Digital Printing Ink products from time to time.

Wood-grain Paper Digital Printing Ink products

stickiness

When Wood-grain Paper Digital Printing Ink products are transferred from the ink fountain to the surface of the ink roller, printing plate, substrate (or blanket), the film of Wood-grain Paper Digital Printing Ink products first splits and then transfers. The ink film is in this dynamic process The ability to prevent the rupture of the ink film shown in the film is called the adhesion of Wood-grain Paper Digital Printing Ink products. During the printing process, if the adhesion of Wood-grain Paper Digital Printing Ink products does not match the performance of the substrate and printing conditions, powder and hair loss of the paper, poor overprinting of Wood-grain Paper Digital Printing Ink products, and printing plate Dirty etc. The stickiness of Wood-grain Paper Digital Printing Ink products can be adjusted with adhesive remover or Wood-grain Paper Digital Printing Ink products additives.
