112 THE TALKIES This latter machine is clearly the only type that can be used for sound-track, but considerable alterations have had to be made before it could be used for the double operation of printing first the picture, and then the corresponding sound-track. The illustration shows the latest type of continuous printer for sound-work. On the left are seen the two spools carrying the rolls of developed negative and raw positive film, the negative occupying the bottom spool, while on the right are seen the spools which collect the exposed positive and the negative respectively. This printer is so arranged that it will perform three operations at will — print the picture with the sound-track in the same operation, print the picture without the sound-track, automatically masking the space to be occupied by the soundtrack, or print the sound-track on to an already printed picture. A number of points have had to be watched, and various hitherto unimportant refinements made. In order to ensure that the very fine variations of the sound-track could be accurately printed, the slot through which the light shines on to the film as it passes through the light-gate has had to be made very much narrower, and any backlash or unsteadiness has had to be gone into
