A watermark is a graphic element that can be placed in the background of your invoice or other company document.

Watermarks are most effective if they are created in light colours.  This way the text over the watermark is easily readable.

A watermark can be a small logo or a large image, covering the whole document with a small logo at the top and an address at the bottom, as shown below.

If necessary, contact a graphic designer for help creating your watermark.

Watermark specifications

For a resolution of 72dpi, the watermark should be 595×842 pixels to fill an A4 page.

72dpi = 595 x 842 pixels
96dpi = 793 x 1122 pixels
150dpi = 1240 x 1754 pixels
300dpi = 2480 x 3508 pixels

The equation is therefore:
dpi/2.54 * 29.7
dpi/2.54 * 21.0

length = (pixels * 25.4mm) / dpi
pixels = (dpi * length in mm) / 25.4mm
dpi = (pixels * 25.4mm) / length in mm

If you are creating the watermark using a graphics program such as ‘Paint’, the default DPI is 96 and the watermark should be a maximum of 793 x 1122 pixels.

150dpi is fine for a graphic on a standard print out or e-mailed documents, whereas 300dpi is better for a formal print out.
