FILE CREATION 4LULU BOOK CREATION GUIDE
Interior Formatting
To publish and print your book, you will need an interior file in
PDF format. This file must contain ALL the contents for your book
(excluding the cover) and must be formatted, styled, and designed
by you prior to uploading.
We recommend using Microsoft Word for simple designs (novels,
memoirs, poetry) and Adobe InDesign for complex projects (photo
books, workbooks, textbooks). Please refer to your chosen page
layout software for specific details about using that software.
Text and Styling
Use the Styles options in Word or InDesign (or your chosen tool) to
define how your text will look. Using Styles ensures consistent text
throughout your file.
Likewise, use formatting options (like Page Breaks in Word) to
control where your content is on the page. Avoid using inline
formatting (like hard returns or paragraph breaks) as these may
cause a shift in content when exporting your PDF.
Color Options
Lulu oers a variety of ink and paper options for your project.
Ink
• Standard Black & White
• Premium Black & White
• Standard Color
• Premium Color
Paper
• 60# Uncoated White
• 60# Uncoated Cream
• 80# Coated White
Carefully review the options to determine the best for your project.
• 60# Uncoated Paper with Black & White ink is ideal for projects
with few or no graphics, like novels, nonfiction, and memoir.
FILE CREATION 5LULU BOOK CREATION GUIDE
• For high contrast, grayscale images, 80# Coated White with
Premium Black & White ink will provide quality printing at a
reasonable cost.
• 60# Uncoated White paper with Standard Color allows you to
incorporate exciting elements such as colored fonts, highlights,
charts, graphs, small photos, or low pigment/saturation color
blocks into your printed work without the premium cost.
• Premium Color is perfect for high-resolution photos and Full
Bleed page coverage. On 80# Coated White paper, you can
exhibit beautiful graphics and vibrant colors.
Photo and Graphic Resolution
Pixels per inch (PPI) are used to describe the pixel density of a
screen (computer monitor, smartphone, etc.). Dots per inch (DPI)
refers to the print resolution of an image by counting the number
of dots per printed inch. The more dots, the higher the quality of
the print (more sharpness and detail). Most print-ready file formats
know how to handle the conversion between the PPI and DPI.
Image Resolution Comparison
300 PPI
Ideal resolution for
complex or detailed
graphics intended for
print.
150 PPI
Minimum resolution for
simple graphics intended
for print.
72 PPI
The standard resolution
for most graphics when
appearing digitally.

Document Color Setup
RGB is an additive process, meaning it adds red, green and blue
together in varying amounts to produce other colors. CMYK is a
subtractive process that uses dierent amounts of cyan, magenta,
yellow and black to remove reflected colors from paper to create
other colors.
Printing uses CMYK, while RGB is used to display colors on screens.
Luckily, advances in printing workflows have eliminated the
necessity of converting from RGB to CMYK. For most projects,
either color space will print without issue.
Why are the Adobe InDesign templates set up in RGB?
Modern workflows, like our process at Lulu, allow printers to use
color profiles that automatically match CMYK ink to RGB values
to produce results that are similar. Following these few simple
guidelines will ensure the best color in your book:
1. If you’re starting from scratch, set up your document as an
RGB file.
2. Use the sRGB color space in your RGB document color profile
and apply the sRGB color space to any RGB images or links
before you make your print-ready PDF.
3. If you’ve already created or converted your file to CMYK and
converted any images to CMYK, keep it in CMYK and do not
switch back to RGB.
4. Solid blacks will print solid at 100% with no other colors added.
If you add color to improve the richness of the black, TAC
(total area coverage) should never exceed 270%.
5. Tint variation is dicult to control in light color (20% or less)
designs.
6. Black & white images should have the color space set to
grayscale.
FILE CREATION 7LULU BOOK CREATION GUIDE
7. The gamma value of a grayscale image should be between 2.2
and 2.4.
8. Use only high resolution photos (300 DPI or higher) and
ensure they are consistent with the document color space,
using RGB or CMYK.
9. Use Premium Color ink and 80# White Uncoated paper when
printing any book with heavy ink coverage.

Formatting Terms
Total Document Size
The total dimensions of the file with bleed included.
Spine Area
The spine width varies based on the number of pages included in
your book. Use the formula or table to determine spine width for
Paperback and Hardcover books. Coil Bound and Saddle Stitch
books do not require spine calculations.
Safety Margin
The border between the trimmed edge and important content
(e.g. text, images, page numbers) to prevent unintended trimming.
Bleed Area
To give books a smooth edge, the pages are printed oversized
and trimmed down. This extra paper that is trimmed away is
called ‘bleed.’ Lulu requires a 0.125 in/3.175 mm bleed margin for
all files. See “File Dimension and Full Bleed” section (page 11) for
more information.
Barcode Area (Optional)
Space reserved for your ISBN barcode. Books not intended for
Global Distribution do not require a barcode or ISBN. Lulu does
not generate or insert your barcode or ISBN for you.
Gutter Area (Shown on page 10)
The gutter is the point where your pages meet. To make books
easier to read, the page margins in the gutter should be larger
than the page margins on the other three sides of the page. See
“Gutter Additions” section (page 10) for more information.
FILE CREATION 10LULU BOOK CREATION GUIDE
Gutter Area
Gutter
The gutter is simply an increased page margin on the binding side
of facing pages to account for the portion of the page inserted and
glued into the bookbinding. If your book includes over 60 pages,
we recommend adding a gutter to your pages.
Coil Bound and Saddle Stitch books do not require a gutter.
If you are creating a Paperback or Hardcover book, reference the
gutter table:

Bleed Margin
When manufacturing your book, we print the interior pages
oversized. Then all the pages are trimmed to a uniform size. The
paper trimmed away is called the ‘bleed.’
We print all book files with a bleed margin of 0.125 in/3.175 mm on
all sides so we can trim the pages to a uniform size.
If your file does not include graphics, fills, or content that extends
to the edge of the page, you can prepare your file at the book’s
final trim size and our system will automatically add the 0.125
in/3.175 mm bleed.
If your formatted file includes graphics, fills, or content that extends
to the edge of the page, use the chart on page 12 to determine
your interior file dimensions.
When to Use Full Bleed
Not Needed
If your file has distinct
white margins around
the body.
Yes
When graphics or
content extend over the
edge of the page.
Yes
If your file includes
accents and graphics
intended to extend to the
page edge.

Lulu Generated Cover
Pick from our book cover templates to create a cover complete
with the title, subtitle, contributor(s), and description. This is a great,
quick option when you are short on time or simply need proof
copies.
Create & Upload Your Own Cover
Once you have uploaded your interior file, we will generate a cover
template you can download that is custom crafted to your book’s
specifications. Use that template to create a cover for your book.
After completing your cover, export it as a flattened, font
embedded PDF to upload to Lulu.
Spine Width Guide
The width of your spine is determined by your page count.
Paperback books require a minimum of 32 interior pages and
hardcover books require a minimum of 24 interior pages.
After uploading your interior file, we provide a customized cover
template with the spine area sized to match your book’s page
count. If you plan to design your own cover or commission a
cover from a graphic designer, use the cover template created after
uploading your interior file to get the exact spine measurements.
Spine Width Calculations
If you prefer to create your cover before uploading your interior file,
you must determine the spine size based on your page count and
adjust the cover templates we provide in our design bundles.
FILE CREATION 14LULU BOOK CREATION GUIDE
Paperback Covers
Use the formula to calculate the spine width.
Spine Width in Inches =
(# of Interior Pages / 444) + 0.06 in

Adjusting the Spine Width
If you intend to create your spine without using the custom
template we provide, you will need to adjust the spine width
yourself. The following instructions using Adobe InDesign and
Adobe Photoshop detail how to adjust your spine width.
Adobe InDesign
Use the page tool to adjust the spine page width.
1. Locate the Page Tool from the tools panel and select it.
2. In the pages panel, click on the spine page (page 2 of the
spread). The page will appear highlighted in the pages panel.
Specify the following settings in the Liquid Layout control
panel (Window > Interactive > Liquid Layout):
; Liquid Page Rule: Object-based
; Object Constraints: Resize with Page: Width
3. After determining your spine dimensions by using the formula
(Paperback) or the calculator table (Hardcover) found in this
PDF, resize the page with the Height and Width widgets in the
control bar. The entire cover should update automatically and
is now ready for your artwork.
FILE CREATION 16LULU BOOK CREATION GUIDE
Adobe Photoshop
Adjust the canvas size, revise the spine width, and
position the cover guides.
1. Subtract the existing minimum spine width dimension listed on
the front cover from the spine dimension found by using the
formula (Paperback) or the table (Hardcover) in this PDF and
add that value to the canvas size. Go to Image > Canvas Size
and enter in the revised total width.
2. Use the path selection tool to select the spine shape layer in
the guides folder and enter the correct width found using the
formula or table.
3. Center align the spine guide, right align the front cover guide,
and left align the back cover guide to the document spread.
Make sure guide layers are positioned correctly and there are
no issues.
Note: The document must be setup with facing pages checked for the
front cover page to automatically shue.

Designing for the Spine
When your book cover is trimmed, it may cause slight variance
in the spine’s position. To allow for this variance, follow these
guidelines:
1. Do not include text that fills the entire width of the spine. Any
variance will cause text from the spine to run over onto the
front or back cover. Leave at least 0.125 in/3.175 mm between
the spine text and the edge of the spine on both sides of the
text.
2. If your book is 80 pages or fewer, do not include spine text.
For books with a low page count, the slightest shift of spine
placement will cause your spine text to run over onto the front
or back cover.
3. Keep the spine the same color/graphic as the rest of the cover.
4. If your spine will be a dierent color from the rest of the
cover, design the cover to include the spine color or graphic
wrapping around the front and back covers.
Trimming & Variance
There are tolerances to consider when designing both your interior
and cover. When building your files, follow the guidelines below to
ensure your project is printed correctly.
Our trimming tolerance is 0.125 in/3.175 mm toward the front and
back cover.
The templates we provide for your interior and cover include a 0.5
in/12.7 mm safety margin. This is in part to help you avoid issues
with spine text alignment on the cover and cut o text/images in
the interior file.
FILE CREATION 18LULU BOOK CREATION GUIDE
Trim Edge
This is the edge of the final printed book cover.
Bleed Edge
IImages should be pushed out to the Bleed Edge, 0.125 in/3.175
mm past the Trim Edge on every side.
Safety Margin
The Safety Margin is 0.5 in/12.7 mm inside the Trim Edge. Text
and other important elements should be placed within the Safety
Margin.

Proofing
Once you’ve completed the publishing process, we strongly
recommend purchasing a single copy to review before making the
book available for sale. Proofing your printed material is critical in
troubleshooting and identifying mistakes. Some issues you may
discover while proofing include:
Human Error
Formatting inconsistencies and typos can slip through the editing
and design process. Your proof copy is an opportunity to look for
those kinds of errors and correct them. The best solution is to edit
the interior file, re-upload, and order a new proof copy.
FILE SUBMISSION 26LULU BOOK CREATION GUIDE
File Error
Low image resolution, transparencies, and unembedded fonts
are common issues that may not be obvious when viewing your
manuscript on a screen. Our system will detect and repair many of
these issues, but some may slip through. If you discover an error
in your printed book that does not appear in your electronic file,
please contact us for help.
Printing Variance
Our trimming tolerance is 0.125 in/3.175 mm toward the front
and back cover. Designing your content with sucient margins
and variance in mind will help you avoid issues with spine text
alignment and cut o text/images around the edges of your page.
