The lighter-coloured of the two inks, which may be used for typing on dark-coloured paper or for obliterating typing on a white paper is preferably composed of a mixture of barium sulphide, titanium dioxide, paraffin oil, and linen oil. The typewriter may be provided with an obliterating type in the form of a plate, the face of which may be roughened, actuated by a special.key or secured over one of the lesser-used types. Specification 25602/13, [Class 100 (iv)], is referred to.
