Can I put my publisher logo on the title page?
Yes. If you publish under an imprint, you can upload a publisher's mark and it appears on the title page of both editions — printed above the imprint name in the paperback, and on the title page of the ebook.
Upload it in the Front & Back Matter tool under Publisher's logo. It's saved with your book, so it travels into the Interior Formatter with the rest of your matter and is still there when you come back to the project.
What to upload
A PNG with a transparent background. This matters more than it sounds. A logo saved on a white background is a white rectangle, and it prints as one — a pale patch around your mark on cream stock, and a bright card on a dark page in someone's ebook reader. Transparency is what lets the paper show through.
A genuinely black-and-white image — not one that merely looks it. Save it as an actual grayscale (or pure black) file. Image editors and AI upscalers routinely leave a faint color cast behind: pixels that read as 6, 5, 5 instead of 6, 6, 6. You cannot see the difference and a printer can, which is the problem — see below.
Bigger than you need, but not enormous. The mark prints about ⅝ of an inch tall. Anything past roughly 1,600 pixels on its long edge is invisible detail that still adds weight to every file you upload and download.
Simple. At the size a title-page mark actually prints, fine detail and thin hairlines disappear or fill in. Look at it at about an inch wide before you decide.
Why color matters so much here
Interior pages print in black ink — see What's inside the print PDF?. We do not silently convert a color logo to gray, because quietly changing your artwork is not ours to do.
What happens instead is that we read the actual pixels of every picture in the book, including your mark. If they are truly neutral, the picture is written into the PDF as a grayscale image and costs you nothing. If there is real color in it, it stays color — and printers price a color interior per page for the whole book, not per picture. One logo with a color cast on the title page can make all 300 pages of a novel color pages.
The export report tells you before you upload, naming how many pictures have color in them. If your mark is named there, re-save it as grayscale and the warning goes away — and so does the price. See The export says I have a color picture.
In the ebook
The mark appears on the ebook's title page too, sized in relation to the reader's text so it stays in proportion when they change the type size.
- It can be a link. Fill in the Website field under Imprint and the mark becomes tappable, which is what readers expect of a publisher's mark. See Links in your ebook.
- It survives night mode. A black mark on a black page is an invisible mark. If yours is black-and-white, it is flipped to white automatically on readers that support a dark theme. This is another reason to give us a real black-and-white file: a color logo cannot be flipped safely, so it is left alone.
- It describes itself. Screen readers announce the mark using your imprint name, so filling in Imprint name is what makes the picture accessible. See Is my EPUB accessible?
Do I need one?
No. Most self-published books don't have one, and a title page without a logo looks completely normal. An imprint name alone is perfectly conventional, and is what most small presses print.
If you don't have an imprint at all, see What is an imprint? before deciding you need a logo for it.
