Term Prepress Technicians/Workers
Code YO-6200.6600-600
Definition Individuals who are responsible for the first stage of printing, preparing the material for printing presses. It is increasingly common for prepress technicians to receive digital files from the customer that contain typeset material already laid out in pages making the typesetting and page layout work previously done by these workers unnecessary. They review the material, check it for completeness and format it into pages using electronic page layout systems. When color printing is required, the technicians use digital color page-makeup systems to electronically produce an image of the printed pages, then use off-press color proofing systems to print a copy (or proof) of the pages as they will appear when printed. Once the customer approves the proof, technicians use laser image setters to expose digital images of the pages directly onto thin aluminum printing plates. Some customers continue to provide material to printers that is more suitable for cold type prepress technology. Cold type processing, which describes any of a variety of methods to create a printing plate without molten lead, has traditionally used phototypesetting to prepare text and pictures for printing. Although this method has many variations, all use photography to create images on paper. The images are assembled into page format and re-photographed to create film negatives from which the actual printing plates are made.
