As well as being experts in epub and related technologies, we also offer composition (typesetting) services, and can work with publishers on XML-first workflows for simultaneous print and digital publication, which can offer significant savings in both time and cost.


For no additional fee, every publisher partnering with Geethik will be assigned a Project Manager to advise and manage their ebook work through every stage of the conversion process, from initial conversations about file formats and layouts, to agreeing upon workflows and keeping you updated on any issues and questions that might arise during the conversion process.

What is an ePub eBook?

An ePub eBook is a digital version of a print book that has been optimized for on-screen reading. EPUB (short for electronic publication) is a free and open e-book standard by the International Digital Publishing Forum (IDPF). The text in an ePub eBook is re-flowable, which means that you can change the font, resize the text, or alter the size of your display, and the text will rewrap itself to fit the available viewing area. EPub eBooks also support embedded content, allowing, for instance, a video to be embedded within an eBook.

Don’t Do’s

close1  Body text must not have a forced alignment (such as left aligned or justified).

close1  Body text must use the default font size and line height. Body text should not use the <font size=”…”> tag or the font-size and line-height attributes in CSS.

close1  Body text should not be primarily bold or italicized. Selected parts of the text can be bold or italicized for emphasis.

close1  Body text should not have an imposed font color throughout the book. If you prefer to use imposed font color in some sections of your book, please do not use too light or too dark color. Light colors will not display with enough contrast on devices set to white backgrounds or on e Ink devices. Dark colors will not display well on devices set to black backgrounds. For grays, use colors within the hex value range of #666 to #999.

close1  Body text must not have a white or black font color. Customers report this as a bad user experience because the text can become invisible when the Kindle is set to the same background color as the font.

close1  Body text must not have a black or white background color. Customers report this as a bad user experience because it can create an awkward, boxy reading experience when the device background is set to a different color and because the text can become invisible when a user changes the background color setting on their device and the font color automatically inverts.

close1  Internal Cover Must Not Appear Twice.

close1  Images must be in the JPEG format. Amazon recommends using an image resolution of 300 dpi or 300 ppi.

close1  Avoid Using Negative Values.

close1  Avoid Using Scripting.

close1  Amazon does not recommend adding additional guide items to the OPF file, because they will be grayed out in the menu options and may cause customer confusion.

close1  IMPORTANT: Guide items, especially the TOC guide item, do not replace the table of contents.

close1  Kindle does not recommend the use of Type 1 (Postscript) fonts.
