Personnel would likely move between the changing rooms (Herren/Damen Umkleide), break room (Aufenthaltsraum), office areas (Sekretariat, Chef-Büro), workshop (Werkstatt), laboratory (Labor), and production (Produktion/Maschinenraum).
Access points could include the entrance/reception and doors leading to various workspaces.
Material Routes:

Material would probably enter from the loading ramp (Laderampe) into the material storage (Materiallager).
From there, it could move through preparation areas (Arbeitsvorbereitung) and weighing (Abwiegen) before reaching the production area (Produktion/Maschinenraum) or specific areas such as ink manufacturing (Tintenherstellung) and bulk production (Bulkherstellung).
Waste Routes:

Waste could be removed from production areas (like production, ink manufacturing, or workshop) and taken outside or to the loading ramp for disposal.
There may also be designated waste disposal rooms or bins along this route.
To visualize these routes directly on the plan, you could draw lines or arrows using different colors for each route:

Green for personnel routes,
Blue for material routes,
Red for waste routes.
