Multi Colour Dying:
With multi colour splash dying the part is dyed in the first colour masked with rubber cement or lacquer, bleached and dyed with the next colour. To remove rubber cement use kerosene or mineral spirits to remove lacquer use lacquer thinner. The resists must be completely dry, if they are not dry and immersed in the dying bath they can cause the dye to coagulate and precipitate out of solution ruining the dye bath and causing spotted dying.
Typical Splash anodizing process:
-Anodize, rinse thoroughly
-dye with first colour
-apply dye resist and allow to dry is a low humidity area
-bleach unprotected areas with 27%(wt) nitric acid
-cold water rinse
-dye again in second colour; rinse, and dry with warm air not exceeding 110°C
-repeat 2 to 6 for as many colours as required
-remove the resist with suitable solvent soak; rinse
-seal in boiling water or steam
