What are micros and what's the difference between XY and XYZ micros?Updated 2 years ago

Micro registration (also known as micros) consists of knobs on the printhead that move a screen vertically, horizontally, and its angle without loosening the screen clamp. If registration is off by a millimeter, a printer can put the screen in place by twisting the knob. Micros increase efficiency, consistency, and quality while decreasing labor and time spent in preproduction. 

Some presses like the Riley Hopkins 250 are equipped with XY micros. You won’t need to manually slide the screen around once you’ve got it centered and clamped down. All you need to do is turn the X or Y micro registration knobs to move the screen up or down, or to the left or right, to get it perfectly aligned.

A Z micro raises the off-contact of individual printheads. The Z micro helps when you’re switching from different substrates in the same job. Presses like the Riley Hopkins 300 come with Z micros. This addition to the XY micro may not seem like a big deal, but it can have a huge impact on your production speed.
