Print on Demand is an availability term often associated with low volume titles. In the old days of metal engraving plates and huge industrial presses, a piece of sheet music that didn’t pay for its place in a publisher’s inventory was usually put out of print (forever). The opportunity cost in time and materials to print an old piece that didn’t sell well would simply be too high when considered in light of new pieces of sheet music that might sell in greater numbers.
In today’s world of digital engraving, digital storage, and quick digital printers, the cost of printing any individual piece of music is much lower. The opportunity cost of actual inventory, however, is still high in terms of dedicated shelf space, warehouse labor, etc. For some titles and publishers, Print on Demand is the best of both worlds.
Print on Demand titles, which otherwise would have been discontinued permanently, can now be kept in a publisher’s ‘virtual stock’ indefinitely by virtue of digital storage. They can also be printed much more efficiently in small numbers thanks to digital engraving and printing. While there is often a lead time associated with Print on Demand pieces, the fact that they can still be sourced at all makes up for the wait.
Many of the advantages of Print on Demand for publishers also translate to print-in-the-store programs for retailers or print-at-home programs for consumers.
