Job Description:

• 1) Engraves designs onto steel dies used to produce textile printing rollers, using engravers' handtools and machines: Measures dimensions of pattern to be engraved in die, using ruler.

• 2) Operates engine lathe to turn steel roller down to size according to dimensions of pattern and copper printing roller.

• 3) Sketches design on steel roller utilizing one of following alternate methods: Lays out reference points on design according to location of one complete pattern repeat, using ruler, dividers, and pencil.

• 4) Covers design with transparent film and transfers reference points to film, using scriber and magnifying lens.

• 5) Sketches design colors onto separate sheets of film, using brushes and ink.

• 7) Immerses steel roller in electroplating solution to coat roller with copper.

• 8) Wraps film around roller, allowing ink in design to react with copper coating to transfer design from film to roller.

• 9) Computes machine settings required to reproduce straight-line designs on roller, using mathematical tables and formulas.

• 10) Plots machine settings on graph paper.

• 11) Mounts steel roller in index-dividing machine and adjusts tracing carriage of machine according to computations on graph paper.

• 12) Lowers tracing-carriage scriber to surface of roller and moves levers of machine to sketch vertical and horizontal lines on roller.

• 13) Mounts sketched rollers in fixture on worktable and engraves outline of design following sketch lines, using gravers' tools.

• 14) Cuts or stipples in ground lines as specified, using gravers' and stippling tools.

• 15) Prints proof print of engraved design on wax paper to verify accuracy of etchings on roller.

• 16) Removes scratches from and polishes roller die, using polishing lathe.

• 17) Punches indentations into edges of die to facilitate transfer of design from die to mill, using hammer and punch.
