Keith Cooper looks at aspects of how to use the monochrome test image freely available on the Northlight Images site. The site has a wide variety of colour and B&W test images, along with articles detailing more advanced uses. http://www.northlight-images.co.uk/printer-test-images/

The test image is used for evaluating B&W print quality irrespective of the software, paper or printer being used.

The use of the image and its variations are described at
