At Fabit, deep etching is the technique we turn to when a client wants a logo or emblem that sits proud of, or sunk deep into, the metal with genuine physical presence.<\/p>\n<h2>How deep etching works<\/h2>\n<p>The process begins by coating the metal with an acid resistant material, known as a resist, everywhere except the areas that are to be etched. This resist can be applied photographically for fine detail or by other masking methods for bolder work. The prepared piece is then exposed to an etching solution, which eats away the exposed metal while the resist protects the rest. The longer the metal remains in the solution, the deeper the etch, which is the fundamental difference between deep etching and its shallow cousin, surface photo etching.<\/p>\n<p>Once the desired depth is reached, the piece is neutralised, cleaned and the resist removed. The recessed areas can then be filled with enamel or paint for colour contrast, or oxidised for a darkened antique effect, or simply left as bare metal to catch shadow. This flexibility in finishing is a large part of the technique&#8217;s appeal.<\/p>\n<h2>Materials suited to deep etching<\/h2>\n<p>Deep etching works on a range of metals that respond predictably to their matched etching chemistry.

A logo etched deep into a brass plate and filled with colour reads as substantial and permanent in a way that a printed or laser marked surface cannot fully match. The play of light and shadow across the recessed detail gives the piece life, and the tactile dimension invites the recipient to run a thumb across it. For corporate awards where a brand mark must be reproduced faithfully and impressively, deep etching delivers both fidelity and gravitas. Colour filling also lets brand colours sit permanently within the metal, protected below the surface plane.<\/p>\n<h2>Design considerations for deep etching<\/h2>\n<p>Etching reproduces detail defined by the resist, so clean vector artwork gives the best results. Very fine lines placed too close together can undercut as the acid works sideways as well as downward, so a design review is important for intricate marks.
