How did william blake’s engravings, which accompanied his poems, provide what one analyst called “the missing link with commerce”?

Being both a skilled artist and poet, he used a method of engraving called "intaglio engraving" which could be mass produced so that it could be more accessible amongst the common person.

Explanation:

Blake's business work to a great extent comprised of intaglio engraving, the standard procedure of engraving in the eighteenth century in which the craftsman chiseled a picture into the copper plate with plates taking months or years to finish, however as Blake's contemporary, John Boydell, acknowledged, such etching offered a "missing link with commerce", empowering artists to interface with a mass audience and turned into an enormously essential movement before the end of the eighteenth century.
