For your logo, we recommend submitting a pdf at the size of your selected notebook (e.g., 9.25 x 11.75 inches) that contains the size and placement of your logo. The art can be in any solid color of your choice. If you are doing a two-color logo please be sure you are using both colors so we can differentiate easily.
If you are not able to generate a pdf file, please upload your logo file as is (png, jpeg, or other image formats) and let us know the size you would like it stamped and its relative location on the book (centered, lower edge, x distance from the top, and so on).
Please reach out for any questions!
