The photo etching process allows us to transfer your drawings onto sheets of brass, nickel silver or copper.

Very high levels of detail can be achieved and the resultant etching an be formed into shapes, dropped into lasered recesses, infilled, painted or lacquered to leave a metallic finish.

THE PROCESS

 

METAL & THICKNESS OPTIONS

BRASS

Available thicknesses: 0.15, 0.2, 0.25, 0.3, 0.38, 0.45, 0.7 and 0.9mm
Maximum etching area: 297 x 490mm (we recommended an A3/A4 size for speed and economy).

NICKEL SILVER

Available thicknesses: 0.25 and 0.45mm
Maximum etching area: 297 x 490mm (we recommended an A3/A4 size for speed and economy).

COPPER

Available thicknesses: 0.3mm, 0.5mm and 1.0mm
Maximum etching area: 243 x 493mm.

Finer detailing can be achieved with thinner thicknesses of metal. The chart below shows the minimum line width and minimum gaps between those lines that can be etched with the range of metal thicknesses:

Photo etching guide

E.g. For 0.25mm brass the minimum line width is 0.30mm and the minimum spacing between those lines is 0.35mm.

 

ARTWORK PREPARATION

We can provide a full artwork service if you prefer. If you are providing us with your own artwork, please follow these guidelines:

It is advised that final artwork should be attempted only after discussion with us first.

 

CONTROLLED ETCHING TECHNIQUE

Iain and his team in our Photo Etching Workshop have developed a way of controlling the depth of etching.

This means we can achieve a much higher definition even on the thicker gauges of metal, where over etching is an intrinsic problem.

Controlled Etching Technique

The left & top is a traditional etching on 0.90mm brass whilst the right & bottom is an etching using the new Controlled Etching Technique. This level of definition was only achievable on the thinnest of metals before.

We can also produce etchings without the need for tabbing, especially useful for small and intricate elements.

Infilling is an additional service offered by our workshop. Infilling is where we colour any half etched area. This is often required with name plates.

We have developed several methods of in-filling and marking surfaces: by laser (black only), with enamel paint, with resin or with spraypaint.

This means we can offer you the best solution suited to your individual project, whether it be for quality, scale, turnaround or economy.

 

METAL SURFACE QUALITY

The metal used for etching is delivered to us pre-coated ready to receive the image from your artwork. This means we cannot see the surface of the metal. The surface of the metal may differ from sheet to sheet (this is particularly the case with nickel silver) and so the surface of the finished work may not be consistent, even with different sheets produced at the same time. The differences occur during the manufacture of the metal and this is not a fault.The main variations which occur are the reflective quality and marks created by the brushes used during the metal manufacture.

We can do work again - this is chargeable - although, unfortunately, the result may be the same because we can't see the surface until the work is finished.

Scratches and gouges are not acceptable surface variations and you will not receive work affected by these. Please call us if you would like to discuss this potential issue.

For quotation for total cost of the etching please email, fax or post us a sketch of your proposed etchings giving quantities, sizes, material, thickness and any other information that is relevant.
