Black-and-white forms with raster background

Fields on such forms are simply white spaces (usually rectangles) on a raster background. The background is made up of individual dots. The recommended size of the dots is no more than 0.1 mm, with the distance between each dot about 1 mm. The size of the dots and distance between the dots are crucial, because a raster background is removed during despeckling rather than during scanning: the program will treat the dots as garbage and remove them. The dots should therefore not be glued together on scanned images.
