who was responsible for inventing and perfecting a movable type printing press?

The person responsible for inventing and perfecting the movable type printing press was Johannes Gutenberg, a German goldsmith and inventor from Mainz, Germany, around 1440. Gutenberg developed a system that included the creation of durable metal movable type from an alloy of lead, tin, and antimony, a hand mould for casting type efficiently, and an oil-based ink suitable for printing on paper and vellum. He adapted a screw press, similar to those used in wine or paper production, to apply even pressure for printing. His innovations drastically reduced the cost and time of printing books, enabling mass production and sparking the Printing Revolution in Europe. Gutenberg's most famous work using this technology was the Gutenberg Bible
