Numbering can be placed anywhere on the form but is usually positioned in an upper or lower corner. An area of at least 1" x 0.5" is required for the numbering. This can be indicated with a box or a prefix, such as "Invoice:" or simply left blank.
It is recommended to position the numbering a minimum of 1" away from the edge of the page.
The desired location for the numbering can be indicated by adding an overprint layer in Adobe Illustrator or InDesign to show where the numbering should go. However, it needs to be done carefully to ensure the overprint element is set up correctly.
If no specific location is indicated, the numbering will be positioned in the best available location with sufficient space (generally in the upper right corner).
