Abstract
Abstract In the present method a digital computer receives a ''''raw'''' test input, which it justifies line by line, and stores in its memory the coded identity and location of each typographic character in the justified text. Also stored in the computer memory are the character-generating data for every typographic character which may appear in the text. The computer is programmed to scan its memory electronically in accordance with the scanning operation of a photographic recorder to provide binary output signals to the recorder which cause the latter to record narrow segments of the typographic characters at the proper locations on the record page.

Claim 1
Independent Claim
211 words
A method of recording a series of justified lines of text on a record page comprising the steps of: storing in the memory of a digital computer digital information designating the page position of each justified line of text and the line position and identity of each typographic character appearing in the text; storing in the memory of the computer, for each typographic character that may appear in the text, digital information for generating narrow segments which make up the entire typographic character; selecting the typographic characters from the computer memory in a sequence corresponding to a predetermined scanning pattern along adjoining narrow tracks across the lines of text; reading out from the computer the digital information for generating narrow segments of the selected characters in a sequence corresponding to the order in which those character segments appear in the lines of text when the latter are scanned in accordance with said predetermined pattern; and scanning a photographic record page rotating on a drum with a photographic recorder in accordance with said predetermined pattern and operating said recorder in response to the segmentgenerating signals readout from the computer to record photographically on the record page the respective character segments as they appear in the sequence determined by said predetermined scanning pattern.

Claim 3
Independent Claim
174 words
A method of recording a series of justified lines of text on a record page comprising the steps of: storIng in the memory of a digital computer digital information designating the page position of each justified line of text and the line position and identity of each typographic character appearing in the text; storing in the memory of the computer, for each typographic character that may appear in the text, digital information for generating successive narrow segments of the typographic character; scanning with a photographic recorder a photographic record page on a rotating drum along successive adjoining narrow tracks which ''''cross'''' lines of text to be reproduced, each extending through the desired page positions of narrow segments of a succession of typographic characters; identifying in the computer memory the narrow character segments in the order of their occurrence in said scanning tracks; and operating said scanning photographic recorder, which scans said record tracks on the record page in succession, to record said character segments in the order of their occurrence in said scanning tracks.
