Printing Process
__________________________________________________________________________________________
Intaglio printing is describe as the opposite of relief printing, in that the printing is done from ink below the surface of the plate. The ink is rubbed into the indentions then, the printing surface is wiped clean. To start this process, a tool called a roulette is used to start adding dimensions to the artwork. The purpose of this is to use different patterns and a variety of tone into the picture. Etching involves having to have lots of polishing and cleaning to the surface. Next you would need to apply a "ground" onto the image. Once it has been prepared with a ground, the smoking process begins. Where the coal is absorbed onto the image. Next, you will scratch at the all black surface to reveal the underlaying copper. The copper parts will be actually transferred onto your final result. After carving the image, you will begin a process called "etching". This process eats away at the bare copper revealed through the coal. Now, you image is ready to be printed. Ink is evenly distributed, and then a dampened sheet of paper Is placed on top of the image. The last step is that it is ran through the press with high pressure.

is the printing process based off of the root word "lithos" meaning stone. This method is using the immiscibility of water and oil. First, the artist must use a greasy substance to draw the image on the lithographic stone. Next, the stone is chemically treated to establish the areas where water goes. One the drawing is established into the stone, you can replace the oil with any preferred color of ink. Other materials such as greasy pencils and crayons are used to create dimension and depth into the drawing. These materials are numbered, and the higher the number the more grease they contain. The greasier the utensil the harsher the line will become. This can be removed by taking this like razor blades or sand paper to remove the grease. Next you apply Gum Arabic to establish the whites in the image. After this you wash the image with lithotine.
