Traditionally, a skilled press operator allowed for misregistration by spreading or choking the ink in an attempt to make the gaps or overlays less noticeable. Also, the page designers played their part by attempting to ‘design out’ any potential misregistration from the page design. Both methods require great skill and time to perfect. The Harlequin RIP's trapping technology handles trapping automatically, as the page is processed by the RIP. A good trapping solution must be flexible enough to support various digital workflows while providing impeccable quality, proofing and previewing. In-RIP trapping accommodates the need for last minute changes of printing conditions without requiring time-consuming human intervention, and it allows users to be able to apply the same page content for multiple purposes. These increase the throughput in prepress systems, resulting in greater profitability.
In-RIP trapping is by far the easiest trapping method to implement since, once the trapping parameters have been entered, trapping occurs automatically without the need for further intervention. Trapping programs fall into the two basic categories: raster trappers and object trappers. Raster trappers analyze for traps on a pixel-by-pixel basis, where each pixel in the rasterized page is considered for trapping. Object trappers work on the PostScript® language objects or vector objects that describe the page. This means they have considerably fewer calculations to make than raster trappers when deciding where to place traps, and are therefore considerably faster than raster trappers. Furthermore, object based trapping improves the quality and accuracy of the trap shape. TrapPro is an object-based trapping engine that uses the Device-Oriented Display List that is generated in the RTI RIP-Kit. This allows the trapping engine to trap everything the RIP renders, with pixel accuracy, and with great speed. The traps are drawn with a brush and it maintains color fidelity and traps real device colors so trapping with extra grays is supported. TrapPro provides the following benefits:
