I barely bought a 6 Color 4 station harco press but don't fully understand the concept of lining up your screens when doing multiple colors on a shirt....my question is how do I set the side clamps when locking in my screens to do so, how do. Adjust the clamps so each screen hits exactly where they need to line up when Doing mutiple colors do I eyeball it by trying o see through the screen to get it alined right or is there another way that I have not yet seen????
