If your book job has a significant mix of color printing and grayscale/black-and-white pages, we can look to see if there will be cost savings to price out the B&W pages separately. We have a one-size fits all formula for this type of job, so in some cases (generally those with small quantities and/or small page counts) there is no benefit and it's better to price it as color. The fastest way to get this information is to enter your job details on the appropriate order form as a full color job, then specify in the Job Notes which pages will print in color versus B&W. Then email us with the quote number and we will get back to you with your custom price. For color copies where the back side is B&W, there is a simpler formula, but this does not math out to savings with quantities under 1000.
