Checkmark Field
A checkmark field is an element of a machine–readable form (usually a square that is called a "check box") in which a mark should
be made by the person who completes the form.
A checkmark field usually has an accompanying text which explains the use of the checkmark.
Possible shapes of checkmark fields are shown in the table below.
Square Circle Underline
Other shapes are also possible, e.g. polygons, ovals, etc.
Checkmark Group
A checkmark group is an element of a machine–readable form that unites several checkmark fields of which only one must be
checked. Checkmark groups are usually accompanied by explanatory text that explains the nature of the choice to be made
Reference Mark
A reference mark is an element of a machine–readable form that is used to facilitate the matching of form images with templates
and to determine the orientation of forms during automated processing.
Before the program can start recognizing the contents of the form, it must match the form with its template. All machine–readable
forms of the same type must conform to one template, i.e. the location of all form elements must be exactly the same on all forms. The
program will attempt to match the form with its template relying on the number and location of the reference marks on the form. If
the program manages to match the reference marks on the form with the reference marks on the template, it will know exactly where
to look for fields containing data to be recognized.
Standard reference marks are listed in the table below.
Black Square
Corner
Cross
Timing Mark
For best recognition results, it is advisable to have standard reference marks on the form, but in some cases line separators, explanatory
text or barcodes can also be used as reference marks. However, standard reference marks are more reliable and should always be your
first choice.
Line Separator
A line separator is an element of a machine–readable form in the shape of a vertical or horizontal black line.
Line separators are used for partitioning forms into several logical segments.
Form Identifier
A form identifier is an element of a machine–readable form that is used for selecting the right template if several templates have the
same arrangement of reference marks.
We recommend using barcodes as form identifiers.
A barcode is a set of vertical black and white lines of differing widths used for encoding information.
Some other elements on the form can also be used as form identifiers.
Picture
A picture is an element of a machine–readable form that should not be recognized and should be exported as an image file.
