Relief Printing

A relief print is an image created by a printmaking process, such as woodcut, where the areas of the matrix (plate or block) that are to show printed black (typically) are on the original surface; the parts of the matrix that are to be ink free having been cut away, or otherwise removed. Printing the image is therefore a relatively simple matter of inking the face of the matrix and bringing it in firm contact with the paper; a printing-press may not be needed as the back of the paper can be rubbed or pressed by hand with a simple tool such as a brayer or roller.
This contrasts with an imtaglio print such as an engraving or etching (although there can also be releif printing), where the areas to print black are below the original surface of the matrix, and the original surface of the matrix will print blank. To print these the whole matrix is inked, and the ink then wiped away from the surface, so that it remains only in the lines (classically) that the artist has made below the surface of the matrix. Much greater pressure is then needed to force the paper into the channels containing the ink, and a high-pressure press will normally be required.
The relief family of techniques includes woodcut, wood engraving, relief etching, linocut, and some types of collography Traditional text printing with movable type is also a relief technique, which meant that woodcuts were much easier to use as book illustrations, as they could be printed together with the text, whilst intaglio prints such as engravings had to be printed separately.

monoprint

Monoprinting is a form of printmaking that has images or lines that cannot exactly be reproduced. There are many techniques of monoprinting, including collage, hand-painted additions, and a form of tracing by which thick ink is laid down on a table, paper is placed on top and is then drawn on, transferring the ink onto the paper. Monoprints can also be made by altering the type, color, and pressure of the ink used to create different prints. Examples of standard printmaking techniques which can be used to make monoprints include lithography, woodcut, and etching
 The difference between monoprinting and monotyping is that monoprinting has a matrix that can be reused, but not to produce an identical result. With monotyping there are no permanent marks on the matrix, and at most two impressions (copies) can be obtained.
Monoprints are known as the most painterly method among the printmaking techniques, a monoprint is often regarded as a non-editionable kind of print and is essentially a printed painting. The characteristic of this method is that no two prints are alike. The beauty of this medium is also in its spontaneity and its combination of printmaking, painting and drawing media.                                                                                     


Intaglio

Intaglio is a family of printmaking techniques in which the image is incised into a surface, known as the matrix or plate. Normally, copper or zinc plates are used as a surface, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint. Collographs may also be printed as intaglio plates. To print an intaglio plate, ink is applied to the surface and then rubbed with tarlatan cloth to remove most of the excess. The final smooth wipe is often done with newspaper or old public phone book pages, leaving ink only in the incisions. A damp piece of paper is placed on top and the plate and paper are run through a printing press that, through pressure, transfers the ink from the recesses of the plate to the paper.
Intaglio techniques are often combined on a plate. For example Rembrandt's prints are referred to as "etchings" for convenience, but very often they have engraving and drypoint work as well, and sometimes no actual etching at all.









This image is very good for fine detail and it is very prominent.
