Fourth problem of image output

Fourth, different color types can not be mixed

Another problem that has centered on the output center is that the designer violates the rules when defining colors in files and placed images: mixing spot colors, CMYK, and RGB colors in the same image or file. For example, they use spot colors and RGB colors to create Illstrator graphics, then place this picture into QuarkXPress, and define four-color separations.

Even if the designer defines colors consistently, the problem still occurs when the same color has a different name. For example, Illustrator and XPress have slightly different naming conventions for Pantone spot colors. So the designer puts Illustrator's picture into XPress. When using the same Pantone color to create another object, once separated, it will be expressed in two different colors. Similarly, CorelDraw sometimes separates whites as spot colors (usually in gradients).

The solution is to rename or redefine the color. In the first case, change the Pantone color name in XPress; in the second case, use CorelDraw's Paper color instead of white.
