Stamp Mark Printing: Methods and Best Practices

Pad Printing
The pad printing process uses a soft silicone pad to pick up ink from a recessed (laser-etched) plate and then press it onto the brush handle. It is particularly effective for printing small logos on curved or irregular surfaces, which is why about 80% of brush logos are created using pad printing. This makes it ideal for tapered or ergonomically shaped plastic handles. By switching to plates with different colors, multi-colored logos can be printed. The printed results are smooth and clear, closely matching the original design. Since pad printing relies on the adhesion of ink, over time (especially when exposed to chemicals or rough usage), the pad-printed logos may gradually fade or scratch. The preparation work for pad printing is moderate (requiring engraving the plate and using a silicone pad), suitable for medium to large scale production, and even small batch custom production, as it does not require bulky screens.

Advantages: Versatile (can print on uneven or curved surfaces); capable of fine details; supports multiple colors.
Disadvantages: Prints may wear off or blur over time (less durable than engraving); a plate is needed for each design; initial costs are moderate. 

Laser Engraving (Marking)
Laser engraving (laser marking) uses a focused laser beam to etch marks onto brush materials. On wooden or bamboo brush handles, the laser burns dark marks; on metal ferrules or hard plastics, it changes the surface color to contrasting tones. The result is a permanent, high-contrast mark that essentially becomes part of the material. Laser marks are "indelible" — they do not fade, peel, or wear off with use. In fact, UV laser marking is "permanently fade-resistant, stain-resistant, and wear-resistant." This makes laser engraving the ideal choice for high-quality brushes intended for long-term use. The downside is that the color is usually limited to monochrome (depending on the material), and the surface should be relatively flat or cylindrical. Equipment costs are high, but no ink or consumables are needed. Lasers are especially suitable for small to medium production runs, as design changes can be made simply through software.

Advantages: Truly permanent, high-precision marks; very durable (resistant to time and wear); no ink or materials required for each part.
Disadvantages: Usually monochrome/single-tone (no bright colors); best for printing on wood, metal, or specialized plastics; expensive equipment; not suitable for extremely fine colored graphics.

UV Digital Printing
UV digital printing uses inkjet heads and ultraviolet-curable inks to print directly onto the handle. Since the ink cures instantly under UV light, it can adhere to various substrates (plastic, wood, metal). This method supports on-demand production of full-color, photo-quality logos and patterns. The finished product usually has a glossy finish (a protective coating is recommended) and vibrant colors. UV prints are typically waterproof and durable enough for everyday use. However, without an additional protective coating, prolonged exposure to sunlight or continuous friction can gradually cause the print to fade or scratch. UV printing has almost no setup cost (you only need to provide the design), making it ideal for customized, small-batch, or multi-pattern projects. The downside is that printing a single piece takes longer than simple stamping, and high-end UV printers and inks are expensive.

Advantages: Achieves unlimited colors/designs in one step; realistic logos; no plates/screens needed (great for customization); usually good outdoor durability after coating.
Disadvantages: Equipment and ink are expensive; ink adheres to the surface (may require coating) and can wear or fade slowly under harsh conditions; slower for large-volume printing.

High-end/Salon-level Hair Brushes: High-end hair brushes (usually with acetate handles) benefit from exquisite craftsmanship. Laser engraving or hot-stamping gold/silver logos on acetate handles can create a luxurious visual effect. UV digital printing on premium materials can also produce vibrant, multi-color logos on high-quality plastic handles. The professional appearance achieved through these techniques makes their pricing more reasonable.
Custom/Gift Brushes: For limited edition or gift brushes, full-color and all-over designs can make the product stand out. UV digital printing technology allows full-color logos and patterns to be customized on any brush. Laser engraving can add a touch of personalized elegance.
