The Color drop-out function allows you to remove one of the
R(Red), G(Green), or B(Blue) color or to convert all the color data
into Neutral Gray. For example, if you want to remove the text or
background in blue color, simply check the Blue Channel then
the text or background in blue color will be removed. On the
other hand, if your original contains various color data, then
check the Neutral Gray to retain all the color data in gray since
removing either one of the red, green, or blue color will
inadvertently affect the rest color data as every color contains
different elements of each of the red, green, and blue channel.
See the result below:
Your original with blue color
background After click the B(Blue) channel
Your original with red watermark After click the R(Red) channel
