![]() 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. Ever wondered what a raster image processor or RIP does? And what does RIPing a page mean? Read on to learn more about the phases of a RIP, the engine at the heart of your Digital Front End.
