Slimbach started planning for a second interpretation of Garamond after visiting the Plantin-Moretus Museum in 1988, during the production of Adobe Garamond. He concluded that a digital revival of Garamond's work would not be definitive unless it offered optical sizes, with different fonts designed for different sizes of text. Unable to create such a large range of styles practically with the technology and business requirements of the 1980s, he completed the project in 2005 with several optical sizes, each designed in four weights (regular, medium, semibold and bold, with an additional light weight for display sizes) using the OpenType font format. It features glyph coverage for Central European, Cyrillic and Greek characters including polytonics. Professor Gerry Leonidas, an expert in Greek-language printing, described it in 2005 as "bar none, the most accomplished typeface you can get for complex Greek texts". Adobe executive Thomas Phinney characterized Garamond Premier as a "more directly authentic revival" than their earlier Garamond, which he described as "a more restrained and modernized interpretation".
