Type of Optical Mark (Bubble or Checkbox) to use when Creating Remark Office OMR Forms

Remark Office OMR is extremely flexible in the form types and mark types it accepts; however, there are a few guidelines that, if followed, will help you to maximize recognition accuracy and minimize data entry time. Choice of mark type/size is one such example.

Although Remark Office OMR can recognize marks of almost any complete shape (circles, squares, triangles…), Gravic Support recommends using circles or ovals. Most respondents have been taught to fill ovals completely, whereas checkboxes are more likely to be checked or X'ed. Although Remark Office OMR recognizes checks and X's quite well, that type of response is much more likely to produce an error. If the check or X runs through more than one mark or through text or graphics on the page, a recognition error may result.

Mark size is also an important factor in recognition. Small marks (i.e., smaller than a capital O (letter) in an 10 point Arial font) may fall below the allowable tolerance, whereas large marks (larger than a capital O in a 14 point Arial font) may actually contain too much fillable space. An example of an ideal mark choice would be a capital O in a 10-12 point Arial font.

Choose a mark which is uniform in thickness (Arial and Courier fonts are good examples). It is best to avoid the Times Roman font which produces a capital O which is thinner on the top/bottom and thicker on the left/right (the top/bottom have a tendency to break-up when scanned).

Note: Do not vary mark size or shape in a single field definition.
