Section 1: Evaluating Tabloid/A3 Color Printers Print Quality Many factors determine the quality of the print output delivered by a color printer. Printhead technology and image resolution, color registration and accuracy and intuitive, user-friendly color adjustments are all key components of a printer's ability to deliver the results you demand to bring your high-end color print jobs in-house. Precise Color Registration The Phaser® 7500 digitally adjusts for mis-registration. Notice the white edges on the "G" and "M" produced by the laser device. The Phaser 7500 automatically makes the necessary adjustments. Phaser 7500 RGB CMY Comparable Laser RGB CMY How the Phaser® 7500 printer exceeds the print quality requirement Color controls Our Xerox-exclusive "Color by Words," a powerful-yet-intuitive color technology, takes the guesswork out of optimizing your color print jobs. With Color By Words* there is no need to manipulate source files. Users simply select the desired color modifications from a drop-down list-such as "pale green colors a lot more green" or "red colors a lot more saturated"-and the image is automatically adjusted. Color registration and accuracy With an ASIC driver to control the light intensity of the LEDs in each printhead, HiQ LED offers better dot-to-dot intensity and timing control, and produces more precise color registration. HiQ LED handles mis-registration issues automatically, simultaneously and continuously, from LED to LED. In fact, tests show that HiQ LED technology corrects color mis-registration even better than comparable laser printers. Also, with Pantone®-approved color tables, the Phaser 7500 prints specified colors consistently and accurately, ensuring that the colors you expect are the colors you get. Plus, true Adobe® PostScript® 3™ gives you the power to print visually rich documents reliably. Plus, text is sharp and readable whether printed in black on colored backgrounds or in color on black backgrounds, thanks to the Phaser 7500 printer's Black Trapping feature. Printhead technology and image resolution The Phaser 7500 color printer features the new Xerox HiQ LED printhead, which offers major improvements in image quality. In the Phaser 7500 there are four individual printheads. With each LED array packing 1200 diodes per inch, the printhead can create many more, and *English only. 6 Xerox Phaser 7500 Color Printer Evaluator Guide
