Is High Speed Stirring Critical to UV Inks?
Thorough, high speed mechanical stirring for one to two minutes is key to optimizing the performance of UV inks. Most UV inks contain between 10 and 20 raw materials, each with a different molecular weight. Likewise, each has a very specific and important function in the performance of the ink. These various components can “settle” in the container and must be mixed to homogenize the ingredients to obtain consistency of color, printability and cure.
