ABSTRACT:
Overstruck text is justified by distributing the white space residue at the end of the unjustified line among the interword spaces for justification. The amount of the residue distributed is used to determine a number of overstrike characters which will overstrike the text including these expanded interword spaces. This is accomplished by placing controls in the text stream during editing to delineate the text to be overstruck. Before printing, these controls in the edited data stream are detected to cause the print line to be first justified by expansion of interword spaces and then followed by overstriking with the appropriate number of overstrike characters determined during the justification process.
