enough that a reader who had not seen the page with the original fonts in place would not notice any issues. Font emulation is therefore very useful for quick-print and corporate reproduction departments, and for display advertising in publication and newsprint. Global Graphics was presented with a GATF Intertech award in 2007 for font emulation. (Available in EBD, HHR, HSR). Harlequin Cross-Modulated screening (HXM) – this halftone technology combines aspects of stochastic and conventional screens to retain fine detail without the problems of noise occasionally encountered with pure stochastic screens. (Available in HHR, HSR). Harlequin Dispersed Screening (HDS) – this stochastic screening technology can be used to retain fine detail in images. (Available in EBD, HHR, HSR). JDF support – the JDF Enabler can be added to a Harlequin RIP to enable it to accept jobs in CIP4's Job Definition Format (JDF). The Harlequin RIP with the JDF Enabler was the first product to be formally certified by CIP4 in 2004. (Available in HSR). Open Prepress Interchange (OPI) – 'thin' PostScript and PDF files containing low resolution "For position only" (FPO) images may be submitted to the RIP, which will replace the image data with high-resolution files held locally. The equivalent Desktop Color Separations (DCS) format is also supported, as are reference XObjects in PDF files. (Available in HHR, HSR). PDF Retained Raster – a technology designed to maximize performance of Variable data printing (VDP) jobs, even if they are delivered as basic PDF files instead of a specialist VDP format. Shared page backgrounds are identified and rendered only once, then merged with variable text foregrounds. (Available in HHR, HSR). Simple imposition – fully automated in-RIP imposition of PDF files for 2- and 4-up saddle stitch, 4-up perfect binding, step & repeat, cut & stack etc. (Available in EBD, HHR, HSR). TrapPro – in-RIP trapping solution, supporting trap zone and trapping parameters delivered in PostScript language or PJTF commands within a PDF file, and also configuration within the RIP's GUI. TrapPro includes a number of advanced features such as small object protection, mitered, sliding, anamorphic, narrowed and feathered traps. (Available in HHR, HSR).
