Technical papers & brochure

One line. Two greens. One typeface.

A preliminary system built on the existing AHLS logo, colours and Verdana — extended with a process-line motif taken from the company’s own deliverables: PFDs, P&IDs and general arrangement drawings.

Motion explains flow

  1. Draw once. Diagrams draw their lines as they enter view — 1.4 s, never repeated.
  2. Flow slowly. Process streams carry a 2.6 s dash cycle. One button pauses it.
  3. Never block reading. Text is never animated in or delayed.
  4. Respect the setting. With reduced motion, diagrams are static and complete.
7.7

Title block

Every sheet, slide and page closes with the same block: identity, revision, status. It is also where this concept states honestly what it is.
