About cheques and CPA Standard 006 regulations
The specifications published in Standard 006 in January 2005 are designed to ensure that high-quality images can be captured from the cheques for a range of purposes, including delivery to customers and financial institutions' internal use, as well as enabling other processing improvements not directly related to imaging.
The image-friendly cheque specifications are described in Part A of the Standard 006 PDF on the Payments Canada website: https://www.payments.ca/sites/default/files/standard006eng.pdf
