Inkjet printing is usually sold as Standard Color or Economy Color. It uses a technology where ink is literally sprayed on the page. Think of hundreds of inkjet heads in rows. As the paper passes beneath, these heads spray various amounts of color to build up the ink coverage. This is definitely not recommended for any books with color pictures or graphics. It’s virtually impossible to get crisp, precise photo-quality images. Inkjet printing is a low-cost printing process usually reserved for cheap advertisement printing like supermarket coupons.
