Ghostscript, GhostPCL, and ColorBurst's Overdrive (for macOS) are examples of software RIPs. For high-end typesetting, standalone hardware RIPs are sometimes used. RS-232) and generated a 'hardware bitmap output' which was used to enable or disable each pixel on a real-time output device such as an optical film recorder, computer to film, or computer to plate.Ī RIP can be implemented as a software module on a general-purpose computer, or as a firmware program executed on a microprocessor inside a printer. Originally a RIP was a rack of electronic hardware which received the page description via some interface (e.g. The input can also be or include bitmaps of higher or lower resolution than the output device, which the RIP resizes using an image scaling algorithm. The input may be a page description in a high-level page description language such as PostScript, PDF, or XPS. Such a bitmap is used by a later stage of the printing system to produce the printed output. The above is an excerpt from our latest white paper: Scalability with the Harlequin RIP ®.Wikipedia Rate this definition: 0.0 / 0 votesĪ raster image processor (RIP) is a component used in a printing system which produces a raster image also known as a bitmap. The Harlequin RIP includes native interpretation of PostScript, EPS, DCS, XPS, JPEG, BMP and TIFF as well as PDF, PDF/X and PDF/VT, so whatever workflows your target market uses, it gives accurate and predictable image output time after time. These are all important processes in many print workflows.

Screening is applied during rendering or after the Harlequin RIP has delivered unscreened raster data if screening is being applied post- RIP, when Global Graphics’ ScreenPro™ and PrintFlat™ technologies are being used, for example.Color management (Harlequin ColorPro®) and calibration are applied during interpretation or compositing, depending on configuration and job content.

In-RIP imposition is performed during interpretation.

RIPing often includes a number of additional processes in the Harlequin RIP® for example: In other environments the output stage is tightly coupled with rendering. Sometimes this step is completely decoupled from the RIP, perhaps because plate images are stored as TIFF files and then sent to a CTP platesetter later, or because a near-line or off-line RIP is used for a digital press. Output: the raster produced by the rendering process is sent to the marking engine in the output device, whether it’s exposing a plate, a drum for marking with toner, an inkjet head or any other technology. It’s only used it in the first sense in this document. The term ‘rendering’ is sometimes used specifically for this part of the overall processing, and sometimes to describe the whole of the RIPing process. Rendering: The display list is processed to convert every graphical element into the appropriate pattern of pixels to form the output raster.

This phase is only required for any pages in PDF and XPS jobs that use live transparency it’s not required for PostScript language pages because those cannot include live transparency. This database is referred to as a display list.Ĭompositing: The display list is pre-processed to apply any live transparency that may be in the job. Each may be an image, a character of text (including font, size, color etc), a fill or stroke etc. Interpreting: the page description language to be RIPed is read and decoded into an internal database of graphical elements that must be placed on the page. The process of RIPing a page requires several steps to be performed in order, regardless of whether that page is submitted as PostScript, PDF or any other page description language. The RIP converts text and image data from many file formats including PDF, TIFF™ or JPEG into a format that a printing device such as an inkjet print head, toner marking engine or laser platesetter can understand.
