In that case, it's a good idea to test all of the fabrics (or at least the ones you are suspicious might bleed) before making the quilt. You can do this by cutting a 2" square or wedge, drop this in a glass of water, and leave overnight. If there is a lot of bleeding into the water, this is a fabric that needs to be prewashed. Also, rub the damp fabric against light colored fabric to see if any dye transfers that way.
As long as there are no heavy bleeders among the batiks, washing the quilt with color catchers should be fine.
