Changing the color
mode of bitmaps
The colors of the
images that you work with in CorelDRAW are based on color modes. Color modes
define the color characteristics of images and are described by their component
colors. The CMYK color mode is composed of cyan, magenta, yellow, and black
values; the RGB color mode is composed of red, green, and blue values.
Although you may not
be able to see the difference between an image in the CMYK color mode and an
image in the RGB color mode on screen, the images are quite different. For the
same image dimensions, an RGB image has a smaller file size than a CMYK image
and the RGB color space, or gamut, can display more colors. Therefore, images
intended for the Web or desktop printers, which require accurate color fidelity,
are generally in RGB mode. Where accurate print reproduction is needed, such as
on a commercial printing press, images are generally created in CMYK mode.
Paletted color images attempt to preserve color fidelity while reducing the file
size, making them ideal for on-screen uses.
Each time you convert
an image, you may lose color information. For this reason, you should save an
edited image before you change it to a different color mode. For more
information about color modes, see "Working with color."
