The lettering is the soul of a glass bottle. First, ensure the clarity of the lettering. Good printing results in sharp edges, without fuzz or distortion. For colored patterns or gradient effects, pay even closer attention to the naturalness of the color transitions.
Another easily overlooked detail is the durability of the lettering. Glass bottles come into contact with water, detergents, or oil during cleaning and daily use, so the lettering must be waterproof and resistant to peeling. You can judge this by checking test samples provided by the seller or referring to actual user feedback. Furthermore, the placement of the lettering is also important-centering it or avoiding curves in the bottle prevents the lettering from stretching and deforming, enhancing the overall aesthetics.
