Grain Orientation

Use the following table to compare the weights of various types of card stock.
Depending on the printer, material thicker than 0.30 mm (0.012 in.) may present feed reliability
problems, and material thicker than 0.17 mm (0.007 in.) may reduce print quality. Contact your
supplier to determine the weight of any card stock you currently use.
See the individual printer specifications in this document for more information about the card stock
weights your printer supports.
Grain Orientation
Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain short,
running the width of the paper, or grain long, running the length of the paper.
The orientation of the grain contributes to the rigidity of card stock and affects feed reliability. The
recommended grain orientation depends on the weight of the stock and whether the printer feeds the
stock short-edge first or long-edge first. For lighter card stocks, grain long is recommended to reduce
potential curl problems. Curl may decrease the ability of the form to move reliably through the printer.
