probably not. acid on blotter paper was originally from acid in solution. the blotter is usually made by pre-measuring an amount of solution that contains the target dose (measured by titration), and then using the blotter to soak up all of the measured out solution. capillary action should lead to even distribution of active compounds throughout the blotter.
