What are the specifications for signature image file?
Recommended Specifications
Max. Width: 500px; Max. Height: 150px; JPEG file format
We recommend 300 pixels per 1 inch on paper in order to maintain a hi-res crispness at 300 ppi/dpi on the PDF. For example: 1.5" wide signature should be 450px (i.e. 1.5 × 300px).
The signature placeholder on the form is 500px wide, so any pixels over that will not be beneficial, and will only increase PDF's file size.
Tip on Positioning:
Save image without any padding at first, as this is sufficient for positioning most signatures on the test report.
To adjust the signature's position on the report, pad the image with white space: add space on top to push image downwards; add space on left side to push image to the right.
