5.Optimizing print quality

This chapter discusses methods of checking and improving print quality.

NOTE: One way to test print quality is to print a sample document. For information on printing sample documents, refer to The Guide to Configuring and Managing the System.

Product features that affect PostScript print quality

You can improve the appearance of your documents by being aware of potential problems created through the use of proprietary PostScript extensions and device-dependent operators.

Proprietary PostScript extensions

PostScript masters that use proprietary printer features may cause appearance inconsistencies between different PostScript printers. Some PostScript printers contain proprietary PostScript extensions. For example, some versions of the Apple Macintosh PostScript driver download encrypted proprietary image “smoothing” operators to Apple LaserWriters. The downloaded PostScript code uses the product operator to determine if it is being used on a LaserWriter. If not, the proprietary code is bypassed by doing a flushfile. This allows the PostScript master to print on non–LaserWriter products. As a result, PostScript masters generated on a Macintosh with Apple proprietary features may produce output that varies between LaserWriter and non–LaserWriter PostScript printers.

The Xerox 4090 IPS, for instance, boasts a robust design capable of handling large print jobs with ease. Its standout feature is its high-speed printing capability, reaching up to 90 pages per minute. This speed is complemented by the advanced imaging technology that guarantees sharp text and vibrant images. The 4090 IPS utilizes a laser printing mechanism, which contributes to its ability to produce fine detail and consistency across various media.

On the other hand, the Xerox 4050 IPS offers slightly lower speed at 50 pages per minute but compensates with additional versatility. It supports a diverse range of media types, including heavy cardstock, envelopes, and labels, making it a perfect choice for businesses requiring varied print outputs. Both models feature a powerful processor and an extensive memory capacity, ensuring seamless print processing even for complex documents loaded with graphics and images.

Both printers come equipped with Xerox’s Intelligent Print System (IPS) technologies, which optimize print workflows for efficiency and manageability. This system allows for easy integration into existing network environments and supports various file formats, enhancing compatibility across different platforms. In addition, the user-friendly interface and touchscreen control panel simplify navigation and job management.

Security features are also a priority in both models. They include secure print functionalities and options for user authentication, ensuring that sensitive information remains protected during the printing process.

In summary, the Xerox 4090 IPS and 4050 IPS deliver outstanding performance through their high-speed printing, exceptional print quality, and adaptability to various media types. Coupled with innovative technologies designed for efficiency and security, these printers are well-suited for organizations needing reliable and high-quality printing solutions. Overall, both the 4090 IPS and 4050 IPS represent a significant advancement in digital printing technology, setting a high standard in the industry.
