Snap-off distance

Measuring of the snap-off distance

For clean prints with accuate register and perfect print image, correct settings of the snap- and

lift-off distances are very important.

If a stencil is not placed perfectly flat in the machine, squeegee pressure is unbalanced because the blade presses down harder on the raised part of the stencil. This results in an uneven, distorted image.

The Sefar measuring wedge provides a simple means or verify uniform snap-off distance.

Simply slide the wedge between all four edges of the stencil frame and the machine bed.

Adjust the snap-off distance in mm.

The optimum snap-off distance depends on the dimension of the frame and the printed image, the tension of the screen, on the ink composition and the desired printing job.
