Readable cylinder labels
A useful information hierarchy puts gas identity and MOD before secondary details. The label should help a diver or fill-station operator find the next value without decoding decoration or cramped handwriting.

Keep the gas name, O2, and He visually stronger than owner, date, or branding.
Place MOD and ppO2 beside the mix so the operating context does not become a detached note.
Pressure, owner, role, and analysis date belong in a predictable secondary area.
Use strong contrast, short labels, stable alignment, and enough space for real field lengths.
Layout decisions
A horizontal label gives the mix and detail fields room to sit side by side. A portrait label needs a stronger vertical sequence. Both layouts must preserve the same field priority instead of shrinking everything to fit.
Gas, O2, He, MOD, and ppO2
Make the values connected to gas identification and depth limit fastest to scan.
Pressure, owner, role, and date
Group the handoff and record fields without competing with the mix.
Stock, ribbon, print density, and margins
Validate the final design with the real thermal-transfer printer and label media.

Label layout does not analyze gas, validate a MOD, approve a dive plan, or replace manual checks. Verify the gas and plan first, review every field, and physically inspect the printed result before use.
Start with the cylinder information, then validate the layout with the gas workflow, label stock, and printer that will produce it.
