Graphic pre-press trades workers design layouts, assembling and formatting text and graphic elements, in preparation for printing. They consult with clients to develop a design brief that meets the client's requirements, and is able to be printed without losing quality or exceeding budget constraints. These workers use a range of computer hardware and software to manipulate images and text, selecting the appropriate colours, fonts, sizes and positions to meet the design brief. When the layout has been finalised and proofs have been approved by the client, they will transfer the design to thin metal printing plates. Alternatively, they will send an electronic copy straight to the printer, depending on the technology being used.
