For V-3007. The result is different from the v-3001 and V-3004, which is located in the criteria that can accept. The result this may be because the temperature of the test set of V-3007 is set to a value greater than V-3001 AND V-3004 to get the surface of the sheet that contains the luster but when measuring the temperature of the material will have a minimum value, the rating a*and b* of normal masterbatch low down slightly.
