Determine the grain direction of light-weight media

Introduction

For optimal runnability the grain direction is important. When the grain direction of a certain media is unknown, you must determine the grain direction according to the following procedure.

Procedure

Action

1

Draw rectangles with the transport direction in the long edge feed direction and in the short edge feed direction on a sheet of the media.

See the picture.

2

Cut the two rectangles out of the sheet.

3

Place the two rectangles at the edge of the table as indicated in the picture.

The rectangle that bends the least has the highest stiffness. This means that the rectangle that bends the least indicates the grain direction, because the stiffness along the grain direction is stronger than in the other direction.

4

  • When rectangle A bends the least, the grain direction is in the direction of the arrows, see picture A.

  • When rectangle B bends the least, the grain direction is perpendicular to the direction of the arrows, see picture B.
