You have three ink and paper options:

• Black ink & 55# cream paper
• Black ink & 55# white paper
• Color ink & 60# white paper

If your paperback is printed with black ink, you can choose cream or white paper. For paperbacks with color ink, you can choose white paper, which shows a higher contrast for images and graphics. For example, you're publishing a textbook with lots of images, tables, and charts. White paper will make these visual elements more striking.

When choosing your ink and paper type:

• Select "color ink" if any images in your paperback are supposed to print in color.
• Set up a separate paperback on your Bookshelf if you have a black & white and color version of your book.
• Remember that the cost for paperbacks printed in color is higher. Paper type doesn't affect printing costs. Learn more about paperback printing cost.

Environmental consciousness is important to us. As a manufacture on-demand company, we produce units only as they're ordered, which reduces excess production. Our ink is chlorine-free, and our acid-free interior paper stock is supplied by a Forest Stewardship Council-certified provider. We currently offer a cream paper for black and white book interiors that is made from 30% post-consumer waste recycled material. We also maintain a commitment to recycling waste materials resulting from the printing process and from daily office operations, and we will continue to review our practices to ensure we are doing our part to protect the environment.

"Bleed" occurs when images, background colors, or design elements extend to the edge of the page. Setting your interior to "bleed" will allow printing at or off the edge of a page. It's used for images and illustrations.

Most books use "no bleed" unless there's a specific reason to apply "bleed." Changing the bleed settings won't change the printing cost.

You have two cover finish options: glossy and matte.

• Glossy finish is shiny. It makes black covers darker and artwork more striking. It's typical for textbooks, children's books, and nonfiction.
• Matte finish has minimal sheen and a subtle, polished look. It's typical for novels and other fiction.
