Canon imagePROGRAF GP-4000 - Manual (Page 499)

Important
• When Monochrome is selected, the printer driver processes image data as sRGB data. In this case,
actual colors printed may differ from those in the original image data.
When using the grayscale printing function to print Adobe RGB data, convert the data to sRGB data
using an application software.
Note
• When Monochrome is selected, inks other than black ink may also be used.
