Wilkin also published ten stipple-engraved prints depicting "Portraits of Ladies of Rank and Fashion" (1797–1803), "executed in a manner to unite the Higher Finishing of Painting with the Spirit and Freedom of Drawing" - three were his own and seven were after John Hoppner, though Wilkin was vexed over "the Difficulty that attends getting Mr Hoppner’s Pictures". Technically, Wilkin's engravings "are among the best examples of stipple, the admixture of etched lines and a vigorous use of the roulette preserving a thoroughly draughtsmanlike style." 
Wilkin managed to stipple-engrave with a quite distinctive style, which was not an easy achievement, since this form of engraving does not lend itself to individual expression.
Frank Wilkin (Francis William Wilkin, 1800–1842) and Henry Wilkin (1801–1852), his sons, also exhibited their paintings at the Royal Academy.
