Tips for Color Printing
A-5
Dithering
Dithering uniformly aligns individual dots of different colored
inks to create the appearance of natural colors. This method is
suitable for printing documents that contain large areas of solid
color, such as bar charts and graphs.
Error diffusion
Error diffusion blends individual colored dots with the colors of
the surrounding dots to create the appearance of natural colors.
By blending colored dots, the printer can achieve excellent colors
and subtle color gradation. This method is best suited for printing
documents that contain detailed graphics or photographic
images.
Image Resolution and Image Size
The resolution of your original image affects the quality of your
printouts. Generally, the higher the resolution, the better the print
quality. However, keep in mind that the higher the resolution, the
longer the wait for processing and printing a document.
Generally, the printed image size is in inverse proportion to the
image resolution, as shown below. The larger the image size, the
lower the image resolution. Conversely, the smaller the image
size, the higher the image resolution.
Note:
Some applications have a function that can correct this relationship.
