THE PROCESS

 

IN-FILLING SERVICE — TRADITIONAL

Infilling is an additional service offered by our Acid Etching Department. Infilling is where we colour any half etched areas with ink. This is often required with name plates. Traditionally infilling has been done has been by hand using pen and ink.

 

IN-FILLING SERVICE — LASER IN-FILLING

We have developed a quicker, more cost effective way of in-filling.

Using a special coating that is applied to the metal surface, our laser can selectively burn the coat into the half etched areas, leaving a matte black finish on the metallic base.

As well infilling half etched areas, we can also accurately transfer artwork onto the surface of any metal surface.

The process leaves the artwork “printed” onto the metal in high visibility matte black.

METAL & THICKNESS OPTIONS

We can etch in brass and nickel in the range of thicknesses below. A maximum etching area of 12’’x 20” is possible, although we recommended an A3/A4 size for speed and economy.

 

BRASS

5,6,8,10,12,15,18,28 and 36 thou (0.125mm - 0.9mm)

NICKEL SILVER

10 and 18 thou (0.25mm - 0.45mm)

 

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:

E.g. For 10 thou brass the minimum line width is 12 thou (0.30mm) and the minimum spacing between those lines is 14 thou (0.35mm).

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

 

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.
