Black-and-white linear forms
These forms usually have no background. All field borders (character cells, checkmark fields and other form elements) are made up of solid black lines. Field borders do not disappear as a result of scanning or despeckling.
Note: Forms of this type must be completed very neatly. If the forms are completed carelessly, letters may overlap the field borders, thus reducing recognition quality. This is because whenever the field content overlaps the field borders, it is extremely difficult for the application to separate the borders from the text. Ideally, the entered text should not touch the field borders.
