6.2 When to Use DECimage
Images processed using DECimage require more time to print than
images printed without DECimage. On smaller images, the high-quality
output using DECimage should outweigh the additional computation time
required. However, on large, high-resolution, full-page images, the additional
computation time is significant, and you have to decide whether or not to use
DECimage. You may want to print your draft copies without DECimage, and
only use it for your final printout.
