The Latin psalter was a major innovation in printing as the first book to utilize color printing (using more than one printed color) and to bear a printer’s trademark, date of publication, and colophon. Who was responsible for printing this piece in 1457?

Johannes Gutenberg.

Explanation:

Hello!

Johannes Gutenberg was born in the city of Mainz, Germany, in approximately 1400 AD.  In 1468, he died.

Gutemberg invented the modern printing press, which is characterized by having mobile types. With his invention, Gutemberg began the edition of the Bible in 1452.

In 1455, due to economic problems, Gutemberg gave his printing to Peter Schöffer, who was his partner.

Finally, Peter Schöffer and Johann Fust edited the Bible in 1456 and then, the Latin Psalter in 1457.

It is believed that Gutenberg had begun printing both books before selling his printing press, which is why he is recognized as the person in charge of those prints.
