Interlock

Interlock is a geometric bitmap type system in four styles each in six weights. In Interlock, the relationship between inked and uninked parts of letters is broken down into even patterns of parallel horizontal or vertical lines. Where traditional type designs are configured in binary contrasts of form and counterform, Interlock’s lines are progressively incremented in weight to provide tonal pattern densities within the body of the type.
