Task 7 print industry

  1. Task 7: Print Industry By Matt Holley
  2. Main Print Sectors Hand • Etching • Linocut • Screen print • Woodcut • Lithography Mechanical • Gravure • Screen process • Letterpress Digital • Photocopying • laser printing • inkjet • desktop publishing The main printing techniques are screen printing, block printing and photocopying. Letterpress, lithography, flexography, and gravure printing are used in commercial manufacturing. Finishing techniques enhance the final product.
  3. Hand Etching • Method- 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. Advantages: • It is a hard skill to learn but once mastered you can earn lots of money • The skill doesn’t revolve around a particular material or colour Disadvantages: • Expensive depending on the materials used • A lot of training required to get into the etching industry Linocut • A design carved in relief into a block of linoleum pattern, design, figure - a decorative or artistic work. Advantages: • carving is enabled, printing is possible, embossing is enabled, rubbing, tough and sturdy, different surfaces, easy for simple designs Disadvantages: • Mistakes are irreversible, it is not 3D, you have to work hard to get texture, hard to cut, limited colour application, hard to clean, hard to get off hands, long time to dry, Time consuming Screen-printing • The screen is made from a fine mesh material fixed to a wooden frame. A stencil is placed under the screen and ink forced through the stencil onto the material below. Screen printing with stencils is best for blocks of colour. Advantages: • Creates unique visual result • Inks used are durable • Vivid colours • Flexible printing techniques Disadvantages: • Very time consuming Woodcut • Is a relief printing artistic technique in printmaking where an image is carved into the surface of some wood, with the printing parts remaining level with the surface while the non-printing parts are removed, typically with gouges. Advantages: • Introduction of paper was a lot cheaper than vellum • Great for mass production • Cheaper than metals • Could be combined with movable type Disadvantages: • Can take a long time to carve, hours or even days • Difficult to carve small details Lithography • A printing technique by which the image to be printed is fixed on a stone or metal plate with a combination of ink- absorbent and ink-repellent vehicles. Advantages: • Fast print runs • Images are clear and fast Disadvantages: • Cannot produce high quality prints • Print quantity must be high • Materials are difficult to use
  4. Digital Photocopying • 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 a image. Advantages: • The process is fast • It is also very cheap Disadvantages: • Lack of reliability • Damaging to the environment Laser Printing Electrostatic printer that focuses a laser beam to form images that are transferred to paper electrostatically. Advantages: • Efficiency and speed • Barely emit sound • User friendly Disadvantages: • With the added benefits it makes them very expensive • Hazardous to the atmosphere and your health Ink Jet • Inkjet printing is a type of computer printing that creates a digital image by propelling droplets of ink onto paper, plastic, or other substrates. Advantages: • Lowest cost of printing on the market • High quality images • The printer doesn’t require a lot of time to heat up before printing Disadvantages: • High cartridge cost • Time confusing compared to laser printing Desktop Publishing • Desktop publishing (abbreviated DTP) 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. Advantages: • Cheap way for businesses to create quality material inexpensively • Option of better programs with more functions Disadvantages: • Requires knowledge to use the programs • The better programs are more expensive
  5. Mechanical Gravure In Gravure printing, the image is made up of small holes sunk in the surface of the printing plate. The holes are filled with ink and any excess is removed. Paper comes into contact with the ink in the holes when it is pressed against the plate. Advantages: • Brilliant photographic quality, bright colours, best possible appearance and highest perceived value for your product. Disadvantages: • Its main disadvantage is the high cost and the time needed to engrave gravure cylinders. Letterpress This is a form of relief printing. In relief printing, the parts to be printed are raised up from the plate. Letterpress printing can be used to produce both type and illustrations. It is used for small printing jobs such as business cards and stationary. Advantages: • Letterpress creates crisp, clear lines and bold images • High pigment level ink is used in printing to create sharp images and typography. Disadvantages: • Slow process • Colour isn’t always high quality • Expensive Screen process A method in which image is transferred to the surface to be printed by means of ink squeezed by a squeegee through a stencilled screen stretched over a frame. Glass, plastic, fabric and wood are popular materials on which to screen-print. Advantages: •Unique visual results •Inks are durable •Can print on a large variety of materials Disadvantages: •Very time consuming •Has to use batch production
