By definition, print on demand (POD) is a digital printing technology mainly used for printing and binding of books. Since the keyword here is “digital technology”, the process is known for fast and easy reproduction of book copies within minutes, though this can only be made with limited number of copies and not for large printing capacity.
This process has been used for reproducing books, booklets, guides and other types of bound manuals. If you intend to order prints from online published books, a print on demand publisher will be the perfect choice whether you are going to order colored copies or not.
For color printed books, you should go for the print on demand color publishing service provided by publishing companies. You will get full colored copies in every printed copy no matter how limited or of small volume your print needs are. Writers and authors themselves can also resort to this print on demand color publishing method since it will help much in promoting their copies to potential readers. Of course, why go for the black and white prints only when you can have a textbook complete with colors and photographic designs anyway.
