9 Nov 1990TL;DR: In this paper, a pipe-lined Raster Image Processor (RIP) is described, which consists of a bus and a number of separate image processing components such as a scaler, a decompressor and various interface circuits.
Abstract: Apparatus for a pipe-lined raster image processor (RIP), that is capable of driving a printing engine at a high rate illustratively for use in an image management system. Specifically, this RIP contains a bus and a number of separate image processing components such as a scaler, a decompressor and various interface circuits. Each of these components is connected to the bus and is capable of undertaking a respective image processing task substantially in parallel with those undertaken by other of these image processing components. In addition, a arbiter is also connected to the bus. The arbiter, typically a microcomputer system, receives a request, from any one of the image processing components (the source component), for service, from another one of the image processing components (the destination component). Then, depending upon the availability of the bus and the destination component, the arbiter defines a data path over the bus between the source and destination components, and thereafter initiates an information (typically data) transfer over the bus and between these components. Once this transfer is complete, the destination component is then able to undertake its respective image processing task substantially independent of the tasks undertaken by both the arbiter and the source component. At this point, both the arbiter and the source component are free to perform other image processing tasks while the destination component is performing its respective task. This pipe-lined operation substantially and advantageously increases the throughput of the RIP.

22 Mar 1995TL;DR: In this article, the publication prolog of a PostScript page description language (PDL) or other PDL file is modified to create traps within an interpreter or raster image processor (RIP).
Abstract: The publication prolog of a PostScript page description language (PDL) or other PDL file is modified to create traps within an interpreter or raster image processor (RIP). The publication prolog is modified to provide the trapping instructions to the RIP, while the script is sent unmodified to the RIP. In a preferred embodiment, modification of the publication prolog to instruct the RIP includes creating a directory of the color objects in the publication, and trapping the color objects in the publication using the directory. Thereafter, the modified publication prolog and script are sent to the RIP and trap areas are created as the publication is rendered.

23 Feb 2000TL;DR: In this article, the authors present a method for imposing and rendering image data, which includes formatting the image data for a surface of a media sheet in an output device space and including receiving one or more page description files defining one or several objects to be located on the surface of the media sheet, receiving a job ticket defining a layout of the objects on the surfaces in a sheet-defined space.
Abstract: A method for imposing and rendering image data. The method formatting the image data for a surface of a media sheet in an output device space and including receiving one or more page description files defining one or more objects to be located on the surface of the media sheet, receiving a job ticket defining a layout of the objects on the surface in a sheet-defined space. Prior to ripping, the layout of the objects is transformed into output device space including rotation or translation of the objects. The objects are ripped creating raster data that is oriented in output device space. The raster data is blitted in blocks without shifting the raster data.

18 Oct 1996TL;DR: In this paper, the authors classify layout data into character data (DC), line image data (DL), and gradation image data(DI) by an interpreter and convert them into RGB data by a color conversion processor.
Abstract: Layout data (L/O) are classified into character data (DC), line image data (DL), and gradation image data (DI) by an interpreter (10), and the line image data (DL) and the gradation image data (DI) are converted into (RGB) data depending on printing conditions and output conditions of an output apparatus (16) by a color conversion processor (18). The gradation image data (DI) are converted into (RGB) data to which an image structure produced upon printing is imparted, by a halftone dot simulation processor (20). These (RGB) data are converted into image data for scanning recording by a raster image processor (14), and outputted as a color proof image from the output apparatus (16).

TL;DR: In this article, an output manager that is included in a prepress workflow between a raster image processor and an output device generates a print production format file by configuring a press profile in response to the output device and the press.
Abstract: An output manager that is included in a prepress workflow between a raster image processor and an output device generates a print production format file. The file is created by defining an output device and a press, and configuring a press profile in response to the output device and the press. The output manager receives a reduced resolution image, modifies the reduced resolution image responsive to the press profile, and stores the modified reduced resolution image in a print production file according to the CIP3 format.
