Why not just publish them in book form instead of releasing them in serialized form?
There are many reasons for this. Some are economic, like allowing the individual issues to absorb production costs and enabling the creators to earn more money up front. Also, though the comics market is starting to become more friendly to original graphic novels, we don’t feel that it is ready to abandon serialized comics completely. Many fans and retailers still prefer the nature of serialized comics, and we feel that audience deserves to have their say.
