Why is the printed logo rubbing off our chargers?

Logo wear usually comes from the print method, ink adhesion to that plastic, the print position, or harsh cleaning. Collect examples, check where wear happens, and ask the factory about print method, curing and rub tests.

The question

Customers say the logo on our branded chargers fades or rubs off after a few months. What causes this and how do we fix it?

Main answer · Wecent Editorial Team

Short answer: Common causes are weak ink adhesion on the plastic, incomplete curing, a print position where fingers or pockets rub it, and cleaning with alcohol or solvents. First collect samples and note where the wear happens. Then ask the factory which print method and ink were used and what adhesion or rub tests were done. Options include changing ink or surface treatment, moving the logo, or using laser marking where the material and colour allow.

How logos are usually applied

Logos on chargers are commonly pad printed or screen printed with ink, or laser marked into the surface. Ink prints offer bright colours but depend on how well the ink bonds to that particular plastic. Laser marking changes the surface itself, so it generally doesn’t rub off, but the result depends on the material and colour, and it may not give the contrast or colour you want.

Why ink wears

Some plastics are hard for ink to grip unless the surface is treated or a suitable ink is used. If the print isn’t fully cured, it stays soft for longer. Coatings such as soft-touch finishes can also affect adhesion. These issues may not appear in a quick check at the factory but show up after weeks of handling.

Where the logo sits

Logos on the edges, on the face that customers grip when unplugging, or on a surface that rubs against pockets and bags wear fastest. The same print in a recessed or less-handled area can last much longer. Photographs of worn returns show the pattern quickly.

Cleaning and chemicals

Alcohol wipes and solvent cleaners can dissolve or soften some inks. If the products are used in offices or clinics with frequent disinfecting, mention this to the factory so ink and finish can be chosen to match.

Fixing it

Share examples and the usage situation with the supplier. Ask what print method, ink and curing were used, and what rub or tape adhesion test the factory applies. Agree a test method for future production samples, and repeat it on pre-shipment inspection. Moving or changing the marking method may need new samples, so plan time for it.

Confirm with Wecent the available marking methods for each model, material and colour.

Three more perspectives

Wecent Editorial Team · Compliance/QC perspective

Add a simple rub and tape test to incoming inspection for branded orders. It catches weak prints early.

Wecent Editorial Team · After-sales perspective

Ask customers how they clean the charger. Disinfectant wipes explain many of our worn logos.

Wecent Editorial Team · Purchasing perspective

Agree the logo durability test in the order, not after complaints arrive.
