Bodoni achieved an unprecedented level of technical refinement, allowing him to faithfully reproduce letterforms with very thin "hairlines", standing in sharp contrast to the thicker lines constituting the main stems of the characters. He became known for his designs of pseudoclassical typefaces and highly styled editions some considered more apt "to be admired for typeface and layout, not to be studied or read." His printing reflected an aesthetic of plain, unadorned style, combined with purity of materials. This style attracted many admirers and imitators, surpassing the popularity of French typographers such as Philippe Grandjean and Pierre Simon Fournier. Bodoni has also had his share of detractors, including William Morris, who felt that his almost mechanical perfection seemed cold and inhumane.
