Advancing the worldwide imaging standard

Adobe PostScript 3 technology advances the state of the art to improve print quality, enhance efficiency, and increase reliability for users in enterprise, graphic arts, and production environments. Graphics capabilities include:

Smooth shading - A Language Level 3 operator that renders gradient fills at the resolution of the target device, producing better and more efficient blends, reducing banding on high-resolution devices, and providing significant performance improvements on selected types of graphics.
Extra grays - A capability of the Adobe PostScript 3 interpreter that provides up to 4,096 levels of each colorant in gradient fills, eliminating banding on high-resolution devices such as imagesetters, platesetters, and high-resolution digital proofing devices.
Idiom recognition - A capability of the Adobe PostScript 3 interpreter that automatically replaces PostScript generated by older applications and converts to new Language Level 3 functionality. This provides immediate access to the smooth shading feature, even when using older applications that don't support Language Level 3 directly.
Masked images - A Language Level 3 operator that enables the printing of images clipped to a raster mask, treating them as layers instead of using a series of points. This allows designers to cut out images using as many points as necessary for high quality images, without sacrificing speed or print reliability.
Fine color controls - A capability of the Adobe PostScript 3 interpreter that provides new Device Independent Color (DIC) functions. This allows device manufacturers to provide more accurate color management capabilities, including handling of CMYK data.
Superscreens - A capability of the Adobe PostScript 3 interpreter that allows printing of photo-quality grayscale images and graphics with up to 256 levels of gray on network monochrome devices.
Fast image - A capability of Adobe PostScript 3 devices that downsamples high-resolution color data before printing on desktop monochrome devices. This optimizes memory usage, reduces network bandwidth requirements, and accelerates the processing of photographic image data.

Enabling efficient digital workflows
Adobe is making the concept of a fully digital, composite prepress workflow a reality. Composite files are files that contain all color data in one single data file. This is unlike separated files where each channel of color (e.g. cyan, magenta, yellow, black, or spot colors) is contained in a separate file. Composite files are compact, efficient, and easier to use than separated files, and can be delivered and printed on a broader range of devices. Adobe PostScript 3 provides the enabling technology to help users in press environments take advantage of composite files and move to a fully digital workflow. The capabilities include:
DeviceN - A new Language Level 3 operator that handles any number of colors, from duotones and tritones, to Haxachrome™ and beyond, in a composite workflow. This feature is supported by Adobe Photoshop® 5.0. It makes prepress applications easier to use and more efficient, representing all color on one single page, instead of using one page per color.
In-RIP trapping - An optional capability of the Adobe PostScript 3 interpreter that executes trapping command at the Raster Image Processor (RIP), automating complex and time-consuming prepress tasks. Trapping is specified, then rendered at print time rather than as a separate production step prior to Ripping.
Direct PDF printing - An optional capability of the Adobe PostScript 3 interpreter that improves workflow productivity by allowing the RIP to accept and print Portable Document Format (PDF) files without printing through an application. Adobe PDF has the same imaging capabilities as PostScript because it is based on PostScript. The underlying architecture of both is the Adobe Imaging Model. What this means is that you can be assured of the highest level of compatibility when printing PDF files on Adobe PostScript printers. Your files will print correctly, with the highest quality and, in many cases, optimal performance as well.
JDF workflow support - Job Description Format (JDF) is an industrywide standard programming language for automating print workflows. It is based on XML and allows process steps throughout print and publishing workflows to electronically interact with each other. Adobe PostScript 3 is fully JDF enabled to support the automation of corresponding RIP functions.
Multi-threaded rendering - Adobe PostScript 3 supports symmetric multi-processing systems by enabling time consuming rendering tasks to be split into multiple threads. Those threads can then be processed simultaneously on multiple CPU's .
