Printing Press Experts: Which is the most intelligently made set of separations to reproduce a grayscale image, right or left?
Advantages of Managed Color Spectral Color Separations for printing Grayscale images:
*Separates files into grays and black so it is impossible to get color casts on press.
*Managed Color Spectral sets only require three inks versus four for traditional separations.
Note: Traditional CMYK separations cannot print grayscale without a pink or green color cast due to ink drift on press.
