Discoloration when printed multiple alumide parts

Hi I ordered several multiple alumide parts a few times now. When you print 2 of the same parts together inside a single cage and dyed them, the inner side of the parts (middle side of the 2 parts) gets discoloration. mostly much much darker than the outside area which is annoying and so hard to correct post process.

My question is, If I order another multiple same parts, can it be printed separately even if they are the same exact part and same dye color??
