Your book can include interior images in black & white or color. Images need to be high quality so they will print out well. You may select Standard or Full Premium Color as the printing color option and provide color images in your PDF. We recommend using images that are of high resolution, such as 300 dpi (dots per inch) or higher, so they will print out crisp and sharp. If your file contains images of lower resolution, they will still pass our printing checks but we cannot guarantee the quality of the printed image.
For your cover, if you provide color images in your PDF, your cover will be printed in color.
Note that the color on your computer screen will not necessarily match the color of your printed pages. Your computer screen shows projected RGB color (Red, Green and Blue), and the printed books show CMYK color (Cyan, Magenta, Yellow, and Black).
It does not matter what type of file your images are saved as originally (e.g. jpeg, .png), as you'll be converting your book interior into a single PDF file prior to uploading to B&N Press, though we do recommend following the same resolution recommendations as noted above.
Note: Not all trim size and format combinations offer color printing. Please refer to the grid for more information.
