Operate or tend photoengraving and lithographing equipment, such as plate graining, pantograph, roll varnishing, and routing machines.

Cuts excess metal and bevels edges of printing plates using routing machine. Mounts finished plates on wood, synthetic or metal blocks either by hand or using automatic plate-mounting equipment. Grains printing plates by wet or dry sandblasting or using glass marbles. Copies printed materials such as documents and drawing using blueprint machine. Applies acid resistant ink to varnished copper roller and examines for ink smears or cavities filled with ink. Paints over pinholes, scratches and reference points on roller using brush and acid resistant paint. Immerses and turns printing roller in bath solutions to dissolve coating, develop image, and dye using electric hoist. Maintains machinery in working order such as automatic film processor and exposure machine. Examines finished blueprint for specified color, intensity, and sharpness of line. Cuts printing plates from sheets of aluminum and zinc using power shears. Examines printing plates with magnifier for uniformity, size, and structures of grain and washes off excess sediment. Rolls out and hammers used printing plates to remove gripper marks and bent corners. Operates machinery such as film processor, graining machine, and varnishing equipment.

Production and Processing -- Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods. Chemistry -- Knowledge of the chemical composition, structure, and properties of substances and of the chemical processes and transformations that they undergo. This includes uses of chemicals and their interactions, danger signs, production techniques, and disposal methods. Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance.

Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Equipment Selection -- Determining the kind of tools and equipment needed to do a job.

Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Visual Color Discrimination -- The ability to match or detect differences between colors, including shades of color and brightness. Near Vision -- The ability to see details at close range (within a few feet of the observer).

Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials.
