What is the Epson ABW (Advanced Black & White) Feature?
Epson's Advanced Black & White system uses software and hardware to reproduce black & white images. This brief article gives you the basics. For more information, search the web and get ready for enough forum discussions and websites to last you several evenings of reading.
Starting with the Epson 3800, three black inks - Light Black, Light-light black, and Black (photo or matte) were added to create consistent black & white prints. Known as Advanced Black & White, the system is fairly easy to use and offers many fine adjustment opportunities. You can use this feature with image files that are color or grayscale. The party piece of this system is that you get neutal prints, pretty much every time. If you so desire, you can also add tone via the control panel (see below). Keep in mind that no paper profiles are used with ABW. This is a "printer color management" workflow.
The main drawback is no ability to preview the final output. For the most part, prints come out neutral and properly exposed - provided you have a properly exposed file! You will find that a few trial prints are helpful before getting full control of the system. We suggest making test prints and playing with the settings and making lots of notes! Your subject matter, shooting style, and file type/quality all play a part. However, after some practice, you will know what to expect from certain image types and setting combinations.
Below is an example of the ABW control panel from an Epson P800 / Windows. A description of the individual settings is further down.
Color Toning - Available settings are Neutral, Cool, Warm, and Sepia.
