Appearance consistency

To control the consistency of output between more than one printer, you must consider the following:

printer resolution and resolution enhancement

printer imaging characteristics

font consistency

proprietary Postscript extensions

The following sections provide guidelines for ensuring consistency between printers.

Printer resolution and resolution enhancement

The most obvious reason for inconsistent output between two printing devices is that they have different resolutions. For example, a 600 by 600 dpi printer has much smoother looking fonts and curves than a 300 by 300 dpi device. For the same physical size (constant frequency) of halftone, you get four times the number of gray levels on a 600 by 600 dpi printer as on a 300 by 300 dpi device. If your document contains scalable fonts or simple line art generated at 600 dpi, the differences between printing it at 300 and 600 dpi are subtle. However, if your document contains bitmaps with a resolution of 600 dpi, printing it at 300 dpi causes a degradation in image quality. Figure 2-1 provides an example of a 300 dpi image and a 600 dpi
