Image Watermarking Guidelines

  • Images need to be either jpg or tiff
  • The ideal file size is between 900×900 and 1800×1800
  • The type of images that work best are either busy rich images where everything is in focus, or images that have coloured backgrounds with a gradient fill
  • Apply any textual elements after watermarking the image, taking care not to obscure too much of the image.
    • If you watermark an image with text in, the text can appear ‘jagged’
  • Avoid images with blurred elements. Blurred elements in images (e.g. blurred backgrounds) can end up ‘jagged’ and pixellated.
  • Avoid images with too much white. White areas cannot be watermarked, and areas bordering the white will look ‘jagged’.
