When the ground shade is dyed to approximat

21、e Light Tan 379, all six colors of the camouflage pattern shall be obtained by subsequent printing using six rollers or screens to match all six colors. The ground shade dying and the overprinting shall be accomplished with organic colorants (see 6.6.1). Resin bonded pigments are not permitted. The
