The Compositor's Proof

A printer's proof sheet showing artkit's paragraph flow: a round medallion, a justified block, two columns.

The Compositor's Proof, a printer's proof sheet with a motto set in a circle, a justified paragraph and a two-column colophon
Click the picture for the full-size render.

How it is made

A motto is set inside a round medallion with tfflow and a hand-written circle boundary procedure. A body paragraph is justified with tfblock, and a two-column colophon set with tfcols genuinely spills from the first column into the second.

% tfcols are just convenience wrappers over), a justified body
% paragraph under tfblock, and a two-column colophon under tfcols,
