TITLE(s): REPEAT-PHOTOCOMPOSING-MACHINE OPERATOR (print. & pub.) alternate titles: composer
Operates photocomposing machine to repeat designs on film for transfer to sensitized copper
rollers used in printing such products as wallpaper and oilcloth: Sketches design layout on
worksheet according to sequence in which design is to be repeated around roller. Computes machine
setting required to repeat design on film as laid out on worksheet, using standard formulas and
tables. Mounts positive print on negative frame, aligning centerline on print with centerline on
frame, and tapes print in position. Masks area around print with black paper. Centers film on
backboard of machine and tapes film in position. Lifts backboard against negative frame and locks in
position. Moves negative frame in position for exposing film to first repeat of design, following
computations on worksheet. Starts compressor that creates vacuum between negative frame and
backboard, drawing backboard against negative frame. Exposes film to light through positive print
for specified time, transferring image from print to film. Repeats process until design has been
repeated along vertical and horizontal plane of film a specified number of times. Removes exposed
film from machine and processes film through series of chemical baths to develop, fix, and rinse
