what is an invintion that has not been made that would benefit renaissance time period

One invention that could have benefited the Renaissance time period is a printing press capable of producing color prints. While Johannes Gutenberg's printing press was a groundbreaking invention, it primarily produced black and white texts. If a color printing press had been developed during that time, it would have allowed for the mass production of colored books, illustrations, art, and maps. This could have significantly enhanced the dissemination of knowledge, improved accessibility to information, and facilitated the spread of ideas and artistic techniques throughout Europe during the Renaissance.
