One of my most unusual enquiries came from Beard Juice. Wayne wanted to sell some beard accessories alongside his new range of beard oils, and chose surgical stainless steel beard trimming scissors. He wanted to brand them with his logo, but knew that this would be a challenge on two levels. Could I engrave on metal? And could I engrave his logo small enough to fit on the largest area available – the hinge area of the scissors?
Engraving tiny logos
Wayne sent me a copy of the Beard Juice logo in black and white. I worked out that to engrave the logo in the right place, it could be 19mm wide maximum. I was concerned that the detail in the logo wouldn’t come out clearly enough as the text lines were very fine, and the feathering around the edges might be completely lost at that scale. It was clear that the copyright logo at the top right would be too small to be seen clearly, so Wayne said I could remove it.
Wayne send me some scissors to perform some sample engravings on. We needed to check whether the stainless steel of the scissors would be compatible with the Thermark metal marking paste. It was also important to see whether or not the logo would engrave at a high enough quality.
Thermark is a mixture of glass particles and black pigment. It looks like a grey paste and it is spread onto the surface to be engraved. After it has dried, it can be raster or vector engraved. We chose raster engraving in this case. The laser melts the glass and traps the pigment onto the surface of the metal as a layer of black enamel. Residual paste is then washed off.
It’s a great technique offering good contrast against stainless steel. But it hasn’t worked with every stainless steel sample I’ve engraved using this method. It did in this case, and the logo came up beautifully despite all my concerns. There’s no substitute for preparing samples. Then customers can be confident that they have a good product at the right price before they commit to investing in new product lines.
I sent the prototypes back to Wayne who was delighted and promptly ordered more for engraving.
