Bembo does not attempt to strictly copy all the features of Renaissance printing, instead blending them with a twentieth-century sensibility and the expectations of contemporary design. An eccentricity of Griffo's first "De Aetna" capitals was an asymmetrical "M" that does not seem to have a serif at top right. So odd it has been suggested it may have been the result of faulty casting of type, it was nonetheless often copied in French imitations by Garamond and his contemporaries. The final release of Monotype's revival did not follow this, although it was available by special order. Monotype also did not copy the curving capital "Y" used by Manutius in the tradition of the Greek letter upsilon which had been used in some versions of Poliphilus and Blado, although not in the digitisation of Poliphilus. Nesbitt has described the capitals as "a composite design in the spirit of [Griffo's] type". Historian James Mosley reports that other changes from the earliest versions were reduction in the weight of the capitals and alteration of the 'G' by adding the conventional right-hand serif, and widening the 'e', and suggests that the numerals of Bembo were based on those Monotype had already developed for the typeface Plantin.
