Section 2: Evaluating Color Laser Printers Evaluating Print Quality Beauty lies in the eye of the beholder, but there are specific attributes you can look for to determine the quality of the print output delivered by a color printer. Color consistency, color calibration capabilities, and advanced color matching are all key components to the ability of the printer to deliver the consistent, reliable print quality your company demands. Look for color consistency In sample print runs, watch for uniformity and consistency in large areas of solid fill. Check for smooth transitions where edges meet. Also, monitor image quality and color consistency from page to page during longer print jobs, particularly after 100 or 200 prints of the same image. Does the printer perform periodic automatic calibration to maintain print-to-print consistency? Include a variety of elements in your test pages Try color graphics, photo images, adjacent primary colors, large areas of solid color, color blends and gradients and text in various fonts, sizes and colors. Check source file and platform compatibility Can the printer handle the versions of PCL or Adobe PostScript that your software might produce? Some popular graphic applications, such as Adobe Photoshop®, Adobe InDesign®, or Adobe Illustrator®, depend on true PostScript compatibility for the best color quality and most accurate proofing capability. Consider the range of color management capabilities Look at the depth and breadth of color management capabilities - is the printer compatible with the most common industry standards (assuring you of image fidelity from screen to print)? Look at the ability to match color from different devices, i.e. copier, digital press, printing press or web pages. How the Phaser 7760 exceeds the print quality requirement: Color quality has to do with much more than just counting dots on the page. The Phaser® 7760 printer blends the best technologies from previous Phaser printer products to provide superior color print quality, meeting the expectations of the most demanding color professionals and graphic artists. Color consistency Xerox is the company that invented xerographic printing, and since that time has remained a leader in the continuous improvement of that technology. The latest improvement is the invention of Emulsion Aggregation (EA) toners. This toner technology is a chemical process that "grows" very small, very consistently sized toner particles - rather than mechanically grinding them - to product very fine color detail and smooth transitions. Automatic density control assures consistent color from the first print to the one-hundredth to the one-thousandth. For the demanding color professional, PhaserCal® allows instrumented routine calibration and comes standard on all configurations of the Phaser 7760. Mixed elements When your document includes mixed elements such as graphics, text and photos - the Xerox-exclusive Automatic TekColor® setting applies the best color correction to each graphic element on the page. This assures you get the sharpest text, the brightest colors and the lifelike images from your original file. A new feature in the Phaser 7760, called "black trapping," improves the look of black text printed against a color background, and of color text printed against a black background. Platform compatibility No matter who on your network needs to print, the Phaser 7760 has them covered. Drivers include: • True Adobe® PostScript® 3TM (default driver) to take full advantage of your printer's custom features • A PCL® driver can be used for applications requiring PCL • Xerox Walk-Up Printing Driver (for Windows) enables printing from a PC to any Xerox PostScript-enabled printer. This is especially helpful to mobile professionals who travel to multiple locations and need to print to different printers. • Macintosh® OS driver (OS 9.x or OSX 10.1 or higher) • Unix drivers (Linux, Solaris™) Xerox Phaser 7760 Evaluator Guide 7
