hey io used ibooks author and the tickets are
Text font size must be consistent for the body of the text throughout the book. Spelling and grammar must be correct.
The following issues are critical errors:
- Pages comprised entirely of text but submitted as scanned images.
- Text and characters submitted as images (diacritical marks, ligature marks, and language characters)
- Spaces and hyphens in the middle of words where not grammatically correct
- Illegible, cut off, or incorrect characters
The book must contain proper formatting. Paragraph indents or line breaks after paragraphs are required.
The book content must not overlap or lack proper spacing.
Those comments seem pretty clear. Are you unable to make the corrections requrested?
