[1] The press of his brother Filippo Giunti (1450–1517) in Florence, active from 1497,[2]: 338  was a leading printing firm in that city from the turn of the sixteenth century.

By about 1550 there were Giunti bookshops or warehouses in Antwerp, Burgos, Frankfurt, Lisbon, Medina del Campo, Paris, Salamanca and Zaragoza,[1] and agencies in numerous cities of the Italian peninsula, including Bologna, Brescia, Genoa, Livorno, Lucca, Naples, Piacenza, Pisa, Siena and Turin, as well as the islands of Sardinia and Sicily.

The classic bibliographic monograph, De Florentina luntarum typographia by Angelo Maria Bandini,[6] details the output of the press at Florence by year from 1497 to 1550.

The most famous book published by the Giunti is the second edition of the Lives of the Most Excellent Painters, Sculptors, and Architects by Giorgio Vasari in 1568.

The first documentary record, from 1427, finds the three brothers Luca, Giunta and Iacopo in the parish of Santa Lucia d'Ognissanti [it], where they lived with their mother; their father Biagio had died.
