Document Summary
Pressure asserted to transfer the image from the plate to the substrate. Every sheet in a press run is identical. There is no way to vary each sheet like you would see in a home printer. Conventional printing processes are generally better suited to longer press runs versus short press runs: Makeready is expensive and time consuming: the longer the press run, the more profitable the job. Typical conventional press runs can range from 500 sheets to over a million sheets. 4 different categories of conventional printing processes: planographic printing. Image area and non-image area are on the same plane on the plate. Examples: lithography, offset lithography: relief printing. Image area is raised above the non-image area on the plate. Image area is recessed below the non-image area on the plate. Another term for conventional printing is impact printing. The term impact printing refers to the fact that the image is transferred to the substrate using physical pressure.
