You can only calibrate the colors to some degree. If you have ghosting from the beginning you should be able to calibrate it away a bit (by cost of colorreproduction). If the filters in the glasses aren't too god it doesn't matter what you do though. You can try with this image: The text should only be visible for corresponding eye. Besides: The more unaffected the brightness is for the unblocked image, the better.
There are quite a few sites that sells cheap anaglyphs. You should be able to find a few by a quick googling.
I even once made glasses myself but i'm out of filterfilm. The film i used was discofilters from Lee: (HT)026-Bright Red and (HT)116 Medium Blue-Green. These filters probably works just as good or even better than any glasses of the market.
