PhotoGrade enhances the printed look of images, such as scanned photographs, by providing more shades of gray and better printed clarity and contrast. If your LaserWriter 12/640 PS has been upgraded to a minimum of 12 MB of memory, you can use PhotoGrade. You can set the printer’s default to have PhotoGrade turned on or off.

You can also change the way the images print by increasing or decreasing the number of gray levels used to reproduce them. More levels of gray produce a more natural-looking photographic quality. However, increasing the number of grays also decreases the resolution of the image. For each level of gray, a unique pattern of laser pulses is required to produce a printed dot. More gray levels require more variations in such patterns, which in turn require the printer to use larger, more noticeable dots. You can experiment with various settings to find the balance that suits your needs.
