Inspect etched work for depth of etching, uniformity, and defects, using calibrated microscopes, gauges, fingers, or magnifying lenses.
Examine sketches, diagrams, samples, blueprints, or photographs to decide how designs are to be etched, cut, or engraved onto workpieces.
Prepare workpieces for etching or engraving by cutting, sanding, cleaning, polishing, or treating them with wax, acid resist, lime, etching powder, or light-sensitive enamel.
Engrave and print patterns, designs, etchings, trademarks, or lettering onto flat or curved surfaces of a wide variety of metal, glass, plastic, or paper items, using hand tools or hand-held power tools.
Prepare etching chemicals according to formulas, diluting acid with water to obtain solutions of specified concentration.
Use computer software to design patterns for engraving.
Expose workpieces to acid to develop etch patterns such as designs, lettering, or figures.
Adjust depths and sizes of cuts by adjusting heights of worktables, or by adjusting machine-arm gauges.
Cut outlines of impressions with gravers, and remove excess material with knives.
Measure and compute dimensions of lettering, designs, or patterns to be engraved.
