Form background requirements
- Use dropout forms or forms with raster field borders if possible.
- Use a color that vanishes during scanning when creating a dropout form. See the list of recommended colors in Recommended Colors for Dropout Forms.
- Always ensure that a there is a space between the explanatory text and the field contents. In the case of dropout forms we recommend that any information be printed in the same color as the form background (except where explanatory text is used as an anchor instead of or in conjunction with black squares). By printing information in the same color as the background, you are then free to place it anywhere on the form, including inside the form fields.
- Do not use blue colors for forms which are to be completed by hand. The blue background may merge with the blue ink which is likely to be used to complete the forms. This will adversely affect recognition quality.
