Preparing Book Cover

File Formats

  • Cover has to be submitted as a single file in one of the following formats:
    • jpg/jpeg
    • tiff
    • pdf
  • Cover can be coloured or black & white.
  • The images used should be of at least 300 DPI/PPI.
  • All the images should be flattened.
  • File's colorspace should Grayscale or CMYK.
  • You can use photoshop, coreldraw etc. to create the images. Covert them to tiff/PDF/jpg before submitting on Pothi.com. If you want to avoid proprietary tools for image editing, you can use open source alternatives like GIMP and Inkspace. You can also design a generic cover with our cover design services.

Pre-requisites for Cover Design

The size of the cover you need depends on
  • Page size of the interior
  • Number of pages
  • Type of Binding

To know number of pages you must have the interior of the book formatted. See the specifications for interior formatting here.

You also need to decide on the type of binding to be used. The availability of a binding type depends on the number of pages in the interior. Check out the binding options here and decide the one you would use your book.

Cover Structure

Important terms used in describing cover:

  • Spine:

    Spine is the part of the cover that covers the thickness of the book. It falls between the front and the back cover. Spine is applicable only to the perfect bound and hard bound books. There is no spine in the saddle stitched books.

  • Bleed:

    The covers for saddle-stitched and perfect bound books should have bleed around them. Bleed is not the part of the final cover when the book is ready. It is an extra area that gets cut-off. Bleed should have an extension of the background of the cover, but no text or graphics that are supposed to appear in the final book. The reason for putting bleed on the cover is that trimming of the book can never be exact. There will always be slight variation. So, if the background of the cover is not extended, you may see a thin white strip on the edges of the cover.

  • Flap:

    The covers for hard bound books need to have flaps. When the cover is pasted on the board, part of it is folded inside to give a smooth look to the book and to completely hide the board. This folded part is referred to as flap. Like bleed this part should have an extension of the background of the cover, but no real text of graphics as it will be covered by the end paper of the book.

The structure of the cover for various binding types is demonstrated below.

Best Practices

  • Don't put text and images (except background) right upto the edge. It is not a good aesthetic choice and content on the edge is also in the danger of getting cut-off.
  • Include all information you want printed on the book. Pothi.com doesn't include anything from its side on the files submitted for publishing.
  • Understand technicalities of image size and keep them in mind while designing the cover.

Cover Size

  • There should be no extra white space around the actual cover with bleed/flap. The cover should be submitted in the exact size as described next. There should be no crop marks on the cover either.
  • Bleed/flap must be equal on all the sides.
