Labeling 3mL Pen Carts: Standard Labels Not Sticky Enough

Standard small labels fail to hold when the curve runs lengthwise along the cartridge instead of across the width. Participants note that adding tape over the ends works but looks poor and can still lift, while rotating the label orientation helps somewhat though it remains unattractive. A larger label size that wraps most of the way around is suggested to spread the adhesive load and still show the liquid level, though printer model limits apply for some users.

• Lengthwise curvature on cartridges weakens label adhesion
• Tape overlays secure labels but affect appearance and reliability
• Alternative label orientation or larger sizes improve hold while allowing level visibility
• Loose carts that travel need more robust solutions than those inserted directly into pens

Nothing here is advice.
