To do this task
Enter the name and location of the file that contains the signature.
For best results, your signature image should have an 11:3 aspect ratio. Your signature image will be sized to fit into
a 2-3/4 inch wide by 3/4 inch tall space and placed directly above the signature line on Intuit-supplied checks.
The preview in the Selected Signature
box is sized using the same 11:3 aspect ratio. If the preview signature looks squashed or stretched, the aspect ratio
in the signature image file is incorrect, and you need to create a new signature image.
