Don't accidentally spray it with perfume or aftershave in duty free either as it will turn completely black!
With regards to reprinting boarding cards at the desk, main airlines will do it as either the system automatically generates a new boarding pass when a bag is added, so they may as well give you a new one anyway, or they are doing so to ensure you get through security. In some places home printed or mobile boarding cards have a higher chance of being rejected due to misreading, so a blanket reprint is done just to avoid time wasting. If I am dropping a bag off I usually check in online and don't bother to print anything. Sometimes I will use an app to generate a digital pass and use that if I'm traveling light, but I mostly travel ID and for that you almost always end up with desk issued thick paper boarding pass.
