스퀴지에 관해 관심이 많으시죠?
일단 "Mesh Tension"까지 올리고 며칠 후에 계속 올립니다.
그렇게 어렵진 않습니다.
한번 읽어봅시다.
시작~
Pulling a squeegee is a skill that develops over time. The ability to control pressure, speed, and angle during a print stroke belongs to that class of knowledge described as muscle memory or feel. The art of creating perfect prints every time is largely the result of pulling many prints and closely examining the results.
When you consider that a skilled printer knows how to adjust his print stroke to compensate for variables like various durometers in squeegee blades, different viscosity inks, mesh counts in screens, and a wide range of substrates, you can see that there is a lot to learn. But since most of this is knowledge that is acquired through practice, many printers find it difficult to teach the knack of pulling a squeegee to newcomers. This is one reason why most of the people who regularly pull a squeegee for a living probably never received more than a half-hour's instruction in their entire career. So, for those of you who may have been slighted in the squeegee education department, here are the basics summed up in one place.
Mesh Tension: The force that pushes back
So many factors in screenprinting are interdependent that it becomes difficult to discuss one in isolation. This is the problem we face when we begin to take a closer look at how a squeegee works. It's really only one half of the equation. The squeegee pushes down against the screen, but the tension in the mesh of the screen also pushes back against the squeegee. . Screen tension is the other half of the action-reaction process that makes screenprinting possible, so we really need to begin our discussion of squeegees by understanding how the mesh reacts to the downward force of the squeegee.
We know the first part of the printing process begins with the squeegee forcing the mesh down against the substrate. The squeegee then moves forward across the screen pushing before it a wave of ink known as the working head of ink.
Only one small portion of the mesh, a narrow line of fabric directly underneath the leading edge of the squeegee blade, comes into contact with the substrate at any one time. Before the edge of the squeegee arrives at a given point, the tension in the mesh keeps the mesh suspended above the surface of the substrate. Immediately after the blade passes, the tension raises the mesh off the surface again. This rapid snap-off of the mesh is essential to creating a clean and unsmeared imprint. Without this effect most types of screenprinting simply won't work.
