Many projects produced for print that incorporate color will save on the cost of ink by choosing 2 colors (not always black and another "color"). If neither of the colors in a 2 color project is black, ALL printable content must be in 1 of the 2 colors. Bar Codes/QR codes can still be read by scanners even if they are in a color other than black.
Saad, I do not see the screenshots attached. Can you please attach the screenshots mentioned for future consideration when this is prioritized.
