The IMPRINT India initiative website has quite a bit of information about its focus domains each of which is subdivided into several sub-themes [Disclosure: I am a part of the team for the Advanced Materials domain, led by Prof. Monica Katiyar and Prof. A.K. Singh of IIT-K]. See also the this brochure.
The Overview is probably where you want to start. The text box on the image says the objective is accelerated research and innovation. Somewhere in the middle of the page, you will find this one-sentence summary of what (this phase of) the initiative is about:
IMPRINT is a first-of-its-kind Pan-IIT and IISc joint initiative to develop a (a) New Education Policy, and (b) Roadmap for Research to solve major engineering and technology challenges in selected domains needed by the country. [source]
The epilogue at the end of the page summarizes the initiative's current phase:
IMPRINT in its first phase is a policy developing initiative covering pedagogy, teaching, curriculum, technology-benchmarking and infrastructure readiness. IMPRINT is not meant only for IITs and IISc; it is a national movement providing an opportunity for the higher echelon institutes in India to integrate with all grass root level institutes, industry and organizations, mutually complement and deliver what the country demands and aspires. Policy is our immediate mandate; technology (products and processes) development and delivery will eventually follow.
