When we talk about screen tension next, you will see that squeegee speed and pressure combine to drop your tension over time, resulting in a rejected print. So, what does the fabric have to do with it? Take for example, two screen fabric types, both 77 mesh but one with a thread size of 55 um and the other of 48 um. The first gives an open area of 28% while the latter gives 36% or 29% more open area for ink to deposit through. The result is the second fabric not only gives more exposure for ink transfer but a better uniform deposit, and less squeegee pressure needed.
