2. Hand Printing 3. Screen Printing Etching Screen printing is a printing technique that uses a woven mesh to support an ink- blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Etching is the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio in the metal. Linocut is a printmaking technique, a variant of woodcut in which a sheet of linoleum is used for the relief surface. A design is cut into the linoleum surface with a sharp knife, V-shaped chisel or gouge, 4. Wood Cut Lithography Woodcut-A relief printing artistic technique in printmaking in which an image is carved into the surface of a block of wood, with the printing parts remaining level with the surface Multiple colours can be printed by keying the paper to a frame around the woodblocks. The art of carving the woodcut can be called "xylography", but this is rarely used in English for images alone, Lithography - Is a method of printing originally based on the principle that oil and water do not mix. Printing is from a stone (limestone) or a metal plate with a smooth surface. It was invented in 1796 by German author and actor Alois Senefelder as a cheap method of publishing theatrical works. In modern lithography, the image is made of a polymer coating applied to a flexible aluminum plate. The image can be printed directly from the plate. 5. Mechanical 6. Letterpress printing Gravure Letterpress printing is a technique of relief printing using a printing press. A worker composes and locks movable type into the bed of a press, inks it, and presses paper against it to transfer the ink from the type which creates an impression on the paper. is a technique of relief printing using a printing press. A worker composes and locks movable type into the bed of a press, inks it, and presses paper against it to transfer the ink from the type which creates an impression on the paper. Letterpress printing was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century until the 19th century and remained in wide use for books and other uses until the second half of the 20th century. Rotogravure (Roto or Gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, is a type of intaglio printing process, which involves engraving the image onto an image carrier.

Screen process Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. 8. Digital 9. Photocopying Laser Printing A photocopier is a machine that makes paper copies of documents and other visual images quickly and cheaply. Most current photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. Laser printing is an electrostatic digital printing process that rapidly produces high quality text and graphics by passing a laser beam over a charged drum to define a differentially charged image. The drum then selectively collects charged toner and transfers the image to paper, which is then heated to permanently fix the image. 10. Screen process Desktop publishing Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Desktop publishing is the creation of documents using page layout skills on a personal computer. Desktop publishing software can generate layouts and produce typographic quality text and images comparable to traditional typography and printing. 11. Inkjet Printing . Inkjet printing is a type of computer printing that creates a digital image by propelling droplets of ink onto paper, plastic, or other substrates. Inkjet printers are the most commonly used type of printer 12. . Hand Etching 1. Many circuits can be etched at once 2. Circuits can be very compact - the etched tracks replace wires and leads 3. All etchings will be identical and therefore all circuits will be identical. the circuit needs to be updated, then the it will need to be re-designed and re-etched from scratch, and that etching uses some nasty chemicals that can be harmful to the environment. Linocut 1. Carving is enabled 2. printing is possible embossing is enabled, 3. tough and sturdy, different surfaces 4. easy for simple designs. 1.Mistakes are unreversible, 2. It is not 3D, you have to work hard to get texture, 3. Hard to cut 4. Limited colour application, hard to clean 5. Hard to get off hands, long time to dry 6. Time consuming Screen print 1.The inks used are very durable the colours are 1. Slow Production Rate: As no machine is used and all of the
