Appendix
Sheet creation reference
You can use paper that you make yourself with this device in addition to the optional paper
that we offer. If you make your own paper, follow the specifi cations below.
(1) Sheet size
Height 110-335.6mm Width 63.5-228.6mm
Do not cut or round the corners on the reference side (timing mark side).
(See P.iv)
(2) Weight and thickness
g/m2 (grams per sheet)
mm (thickness)
(3) Paper quality
OCR paper, quality paper, or recycled OCR paper.
(4) Printing ink (printing surrounding mark fi elds)
When the wavelength of the OMR reading sensor light source is 940nm,
use spectrum band B900 to measure the PCS and use ink at PCS 0.15 or
less. Print timing marks in ink at PCS 0.85 or higher.
When the wavelength of the OMR reading sensor light source is 660nm,
use spectrum band B680 to measures the PCS and use ink at PCS 0.15
or lower. Print timing marks in ink at PCS 0.85 or higher.
(5) Printing position accuracy
Parallelism
Perpendicularity Adjust printing perpendicularity for timing marks and
Other
(6) Prohibited printing zones
Do not print between timing marks, or between the top-end (bottom-end)
timing mark and the top edge (bottom edge) of the mark sheet.
Top-end margin*: 9mm or more from the top edge to the fi rst timing mark.
Bottom-end margin: 9mm or more from the last timing mark to the bottom
Side margin:
(7) Direction of paper grain
Feed paper in the direction of its grain to eliminate curling.
