All new print heads will be built using photolithography, and all from one piece of plastic.

Both of these surfaces would be created by photolithography, the process used to make computer chips.

The problem is that photolithography and etching are not perfectly accurate, so not all the resulting transistors are the same size.

Normally, the various parts of a transistor are made using photolithography.

In the past, HP created inkjet print heads through a complex procedure where some parts were built using photolithography and other pieces were built using a mechanical process.

The technique should hold up in the real world despite ditching typical photolithography, the company says: the nanoimprinting remains useful in the error-prone world of storage, and it should scale as the patterns get smaller.
