Fine-tuning print jobs

Problems sometimes occur when you are printing text to a non-PostScript printing device; for example, lower numbers of fountain steps can result in banding. You can specify the number of steps in the fountain fills in a print job. A higher value results in a smoother blend, but the printing time is longer. You can decrease printing time by specifying driver compatibility for non-PostScript printing devices.

If a printing device has difficulty processing large bitmaps, you can divide a bitmap into smaller, more manageable chunks by setting an output threshold. If any lines appear when the printing device prints the chunks, you can set an overlap value to produce a seamless image.

When printing color print jobs to a black-and-white printing device, you can specify whether to print in black or grayscale.

You can rasterize a page of a print job. Rasterizing a page converts it to a bitmap and improves the print speed when printing to non-PostScript printing devices.

To reduce file size, you can downsample bitmaps. Because bitmaps are made up of pixels, when you downsample a bitmap, the number of pixels per line decreases, which decreases the file size.
