Illustration Submission Guidelines

To make sure that your book's publication proceeds smoothly, you must follow these guidelines for all images, whether they are pictures, graphs, tables, charts, maps - anything that's not plain text. Each illustration must be submitted separately (not embedded in the text) at the same time as you submit your manuscript, along with your completed illustrations checklist. Only once we have all the files can the production process can begin. Remember to include a List of Illustrations after your table of contents if you'd like this to be included in your book.

You will need to clear permission to use images in copyright before submission. For information regarding copyright and permission to reproduce images, refer to the Clearing Copyright page.

Unless you have agreed otherwise with your Commissioning Editor, all illustrations will be printed in black and white.

If you have any queries, simply ask your Assistant Commissioning Editor.

Preparing your illustrations

Illustrations should be supplied as digital files that are of a high enough quality for printing. If you find an image online, check the quality before submitting it because most will not be of a high enough resolution to print. You might need to request a high-resolution version from the copyright holder.

Scanned images

  • Photographs should be scanned at a minimum of 300 dpi
  • Line illustrations should be scanned at a minimum of 1200 dpi
  • Save as a TIFF or PDF image for PC
  • Final size of the scan to be approximately 250 x 200 mm

Computer-drawn illustrations

  • Create at a minimum of 300 dpi and save as a TIFF, PDF or EPS image for PC
  • Image size to be approximately 250 x 200 mm
  • Tints: if using a tint, this should be between 15% and 70%; do not use pattern or colour fills
  • Line weights: lines must be a minimum of 1pt to ensure they are still visible when the image is resized

Films stills

  • Save at a minimum of 300 dpi and save as a TIFF image for PC
  • Final size of the still to be approximately 250 x 200 mm

Illustration file types

  • TIFF: the highest quality image for printing and our preferred format. Do not compress your TIFF files.

  • PDF: this is the preferred file format for text-based illustrations such as graphs, tables and charts.

  • EPS: images can also be supplied as EPS files, with a laser print for identification.

  • JPEG: this is not a preferred image format for books because it is a 'lossy' format - JPEGs are always poorer quality because they sacrifice image data to make the file size smaller. If you have no other option, you can send us JPEGs but you must ensure that they are at least 300dpi.

  • Unacceptable file types: MS Word and Excel. If you have an image generated in one of these programmes, such as a graph or table, save it as a PDF.

Numbering your illustrations

  • Number figures by chapter and figure number in that chapter
    • e.g. the first figure in chapter 2 is Figure 2.1 (even if there are no images in chapter 1)
  • Number tables separately to other illustrations
    • e.g. table 1.1, table 1.2, and so on
  • If your book has a plate section, number your plates separately to other illustrations, based on where the plate is first referred to in the text
    • e.g. plate 1
  • The file name of your illustrations should match the illustration number in the text
    • e.g. figure 1.1 in the text should be called figure1.1.tif, the first plate mentioned should be called plate1.tif

Submitting your illustrations

  • Illustrations should be submitted to your Assistant Commissioning Editor as individual files along with one illustrations checklist for your book
  • Submit your illustrations at the same time as your manuscript and submission forms
  • Use a secure file transfer service to send your illustration files to us - we recommend WeTransfer
  • If the typesetters raise any queries about the illustrations or their placing, we'll get in touch with you to confirm

Print images

We strongly prefer digital images and will only accept print images in exceptional circumstances. Speak to your Assistant Commissioning Editor to discuss submitting print images.

If you are supplying print images, mark each illustration very lightly on the back (in the corner) in a soft pencil with its number (e.g. ‘Figure 4.1’). Send your print images to your Assistant Commissioning Editor by recorded post.
