An Introduction to Blockbooks
What is a Blockbook?
A blockbook is a book made up from pages which have been printed
entirely - both pictures and text - from woodcut blocks.
Blockbooks of mid-fifteenth century Europe were often printed, not with a
press, but by laying the sheet of paper over the inked block and
rubbing the back of the paper with some rounded object (a "rubber" or
"burnisher") to transfer the ink. (The technique will be familiar to many
people who have done some
introductory experiments in printing, perhaps in school art classes.)
When you print this way, you can only print on one side of the sheet,
since the rubbing of the "verso" would damage the printing on the
"recto". A common way of binding books printed with this technique
involved stacking the sheets so that
alternate openings of the book would reveal a pair of printed pages,
then a pair of blank backs. These blank openings were frequently
glued closed.
Why Blockbooks?
The blockbook technology was not, as you might imagine, an early stage
of printing from which printing with moveable type evolved. In fact,
the age of the blockbook in Europe was contemporary with the first
two or three decades of printing from moveable type; most blockbooks
are dated in the 1450's, 60's or 70's. The appearance and persistence
of this rather painstaking technology in the face of what has proved
to be a superior way to print, can be explained on economic grounds.
Although it is more versatile to have a font (or several fonts) of
type and a stock of blocks which can be used in more than one
publication, or several times in the same publication, blockbook
printing does not require the publisher to own either type fonts or
press. In addition, one can conveniently print in small editions,
without incurring the labor cost of setting the type. This reduces
tremendously the financial risk of printing at a time when the cost of
paper was a major factor in the economics of publishing (Hindman).
(Modern technology has produced the potential for an analogous
situation, with the emergence of publication-on-demand formats.)
In addition, the reading public (whose tastes, preconceptions, and
prejudices publishers are known to have catered to) must
have found the appearance of the blockbook familiar, with its
manuscript-like text and its vivid coloring over a print which
resembled a sketch.
