Application of Ink-Jet Marking to the Titling of Processed Photographic Film.
Abstract
Use of an electrostatically deflected jet of liquid ink offers excellent promise as a method of marking processed aerial reconnaissance film with alphanumeric titles, overcoming the fusing and clean-room contamination problems of the Automatic Film Titling System BS-8 (XW-1), an earlier titler using xerography. This report summarizes the design of an improved titler using the data-handling system of the BS-8, its frame detector, and some of its other components, but employing a new transport and an ink-jet printing system similar to that of a commercial page printer. The titler accepts input information on punched paper tape, optically senses when each frame is in printing position and then prints two lines of letters, numbers, and symbols parallel to the edge of the constantly moving film. 70mm, 5 inch and 9-1/2 inch wide film in lengths up to 1000 feet may be titled. The same title may be repeated throughout a roll by gluing the input tape in a loop. Characters are formed on a 9 x 11 dot matrix; any of six character sizes may be selected on a front panel control. In addition to improving title adhesion and cleanliness over the original BS-8 the new titler is anticipated to provide a 20 percent increase in operating speed to 120 characters per second. A further speed increase to 450 characters (117 ft/min) is shown to be possible with changes in the data system and addition of a microwave dryer. (Author)
