While utilizing the Interior Reviewer tool to review your interior file, you may have received one or more notifications that your file has errors, warnings, or has had automatic "fixes" applied. While the Interior Reviewer tool will display errors and their locations within your document, you must make any necessary changes in your document.


Errors: These prevent your file from printing properly and must be corrected in order to move forward with your interior.


Warnings: These do not prevent your file from printing, but indicate quality concerns. We recommend correcting these errors to ensure a high quality finished product.


Automatic Fixes: these fixes include the removal of information that is considered unnecessary for printing, or changes to the structure of the file that produce a better quality interior without impacting your formatting.


Trim Size


If you have uploaded a manuscript with a trim size other than the one you selected, Interior Reviewer can adjust the file to fit in one of two ways, and you can download the modified file.


Paste Into Template

(Best choice for lightly-formatted documents)

This option "flows" the manuscript's content into a template formatted for your selected trim size, and will not adjust text or image size. Your overall page count will change as the physical size of the pages is increased or decreased, and any manual formatting such as hard returns or multiple spaces may not appear as intended.


Page Scaling


(Best choice for heavily-formatted documents)


Unlike pasting your content into a new template, page scaling shrinks or enlarges each page and its contents proportionately to fit the selected trim size. Because each page and its content are simply made smaller or larger, any manual formatting will appear the same and your page count will not change. Since the overall scale of the page has changed, the size and resolution of your fonts and images will change as well. When an image is scaled up, its resolution will decrease and become grainier. Conversely, when an image is shrunk, its resolution will increase and become clearer.


Margins & Bleed


Interior Reviewer will notify you of any text, images or line art that extends into the margins and any graphics which are intended to bleed but do not extend far enough beyond the trim line.


Margin Issues


When printing a book, margins are utilized to ensure that all information is visible and the reader?s view is not obstructed. A margin of 0.25" is required on the three outside edges of each page. This ensures that the information will not be trimmed when the book is produced and that the reader can easily view the page. The side of each page where the book is bound is known as the "gutter margin," and will vary based on the number of pages in the book. The more pages in the book, the wider the gutter margin is required to be in order for the text to be easily visible. The two methods described above, "Paste Into Template" and "Page Scaling," will resolve most margin issues, but you will need to correct any remaining errors.


Bleed Errors


If you intend to have images or background artwork that extend to the very edge of the page, then your book should include "bleed." Bleed is a slight extension of the page beyond the trim lines so that the graphics will not fall short of your desired trim edge when the book is trimmed or if any print variance occurs. If an image is intended to bleed, it must extend to 0.125" beyond the trim line. If Interior Reviewer determines that the graphics do not extend far enough, it will notify you that there is a bleed error.


Embedded Fonts


Interior Reviewer will search for any unembedded fonts, and embed them if possible. It will alert you to any unembedded fonts that it is not able to embed for you.


Font Is Missing


Typically, when a PDF is created, any fonts that were used are included, or "embedded," as a part of that PDF file. PDFs can be created without including the font, but they cannot be printed without them. Interior Reviewer can embed many common fonts and will attempt to do so if it does find unembedded fonts. However, any fonts that could not be embedded will result in this error.


Font Was Embedded


This notification occurs when Interior Reviewer identifies that a font was not embedded in a PDF file and can then successfully embed it. If you do receive this notice, it is recommended that you review the document carefully within Interior Reviewer for any slight visible changes that may have occurred.


Image Quality


Interior Reviewer will analyze the quality of any images that are included in your document, and alert you if any images are low resolution.


Low Resolution Images


All digital images have a "resolution," which is a measurement of the amount of detail an image has. The higher the resolution, the more detailed and clear the will be. We typically refer to resolution in terms of how many dots, or small pieces of visual information, there are in a square inch of the image. For an image to be high-resolution, it is generally considered to have 300 or more dots per inch (DPI) when the image's dimensions are the size at which you want it to be displayed. If an image is stretched out to be made bigger, those dots become bigger, and thus the number of dots in each square inch decreases. Because the dots become bigger, the image will start to appear blocky or pixilated. It is recommended that you include high resolution images in your interior.




Interior Reviewer will analyze the structure of your uploaded document, and it will alert you if it fixes any issues.


Removed Annotations


PDFs can contain many useful interactive features that help illustrate, notate, or complement the information provided within them. It is not uncommon to see features such as hyperlinks, bookmarks, review notes, video, JavaScript, and other interactive items in a PDF. However, while these features are useful in a digital reading experience, they would not function in a physical book. As such, they are removed so that the document can be printed correctly.


Removed Form Fields


Word documents and PDFs have the ability to contain interactive "form fields," which are areas where a reader can input information digitally. In a physical book, this is not possible, and interactive form fields are non-printing objects. These fields are removed to ensure that what you see on screen is an accurate representation of how the book will appear in print.


Flattened Layers


PDFs have the ability to contain "Layers." Layers are a way of visually presenting information by stacking it to determine what can be seen. In other words, placing an object on a top-most layer will block that area on the layer beneath it from view. Layers can preserve information that is not visible, but when printed, the hidden information is unnecessary. Therefore, including layers can cause problems with the printing. As such, layers are "flattened," which means that all layers are combined with the end result being the same visible outcome.
