Digital steganography achievement may be in the anatomy of printed documents. A message, the plaintext, may be aboriginal encrypted by acceptable means, bearing a ciphertext. Then, an banal covertext is adapted in some way so as to accommodate the ciphertext, consistent in the stegotext. For example, the letter size, spacing, typeface, or added characteristics of a covertext can be manipulated to backpack the hidden message. Only a almsman who knows the abode acclimated can balance the bulletin and again break it. Francis Bacon developed Bacon's blank as such a technique.
The ciphertext produced by a lot of agenda steganography methods, however, is not printable. Acceptable agenda methods await on annoying babble in the approach book to adumbrate the message, as such, the approach book have to be transmitted to the almsman with no added babble from the transmission. Printing introduces abundant babble in the ciphertext, about apprehension the bulletin unrecoverable. There are techniques that abode this limitation, one notable archetype is ASCII Art Steganography
