Task 7: The Print Industry

Hand

Etching Method Etching is a form of intaglio printing, where an image is

created by cutting or engraving into a surface ink is pushed into the cut lines

Traditionally a copper sheet is used, now days we use etching card which is able to be cut into with just a sharp pencil.

Then it gets pressed against paper which creates a print.

LinocutMethodLinocut is a printmaking technique, a variant of woodcut in which a sheet of linoleum (sometimes mounted on a wooden block) is used for the relief surface. A design is cut into the linoleum surface with a sharp knife, V-shaped chisel or gouge, with the raised (uncarved) areas representing a reversal (mirror image) of the parts to show printed. The linoleum sheet is inked with a roller and then impressed onto paper or fabric.

Looks good Can be massed produced

Takes along time Can be smudged easily

Screen printMethodScreen printing is a printing technique that uses a woven cloth to support an ink-blocking stencil to get the image you wanted

Advantages DisadvantagesCan be mass producedLooks good Can be done in colour

Can smudge Takes a long time to do

WoodcutMethod A image is carved into a block of wood, with the parts

to be printed remaining level with the surface. While the parts printing parts are removed. The areas to show white are cut away with a knife or chisel, leaving the image to show in black at the original level.

Looks really goodCan be mass produced

LithographyMethod Originally used an image drawn with oil, fat, or wax

onto a smooth surface called a limestone plate. The stone was treated with a mixture of acid and gum Arabic. etching the portions of the stone which were not protected by the grease-based image. The etched areas retained the water. A oil based ink was then put on and would be repelled by the water, sticking to the first drawing only.

Advantages Disadvantages

GravureMethod In gravure printing, the image is made up of

small holes in the surface of the printing plate. The holes are filled with ink and any extras removed. Paper comes into contact with the ink when it is pressed against the plate.

Screen PressMethodScreen printing is a printing technique that uses a woven cloth to support an ink-blocking stencil to get the image wanted. The attached stencil forms open areas of cloth that transfer ink or other materials which can be pressed through the cloth as a sharp-edged image.

Advantages Disadvantages

The ink might smudgeCant correct or change it once its been done

Easy to doCan be mass produced

Digital

PhotocopyingMethod 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 as a image. Heat, pressure or a combination of both is then used to fuse the toner onto the paper. (Copiers can also use a ink jet, but xerography is normal for office copying.)

Advantages Disadvantages

QuickEasy to doCan be mass produced

Complicated to fix if it breaksYou have to have electricity

Laser PrintingMethod a laser beam goes over a charged drum to get a differentially charged image. The drum then selectively collects charged toner and transfers the image to paper, which is then heated to permanently keep the image.

Advantages Disadvantages

Cant smudgeQuick and easy Image is there permanently

If there's a mistake you have to start againHard to fix if it breaksHas to have electricity

Ink JetMethodInkjet printing is a type of computer printing that creates a digital image by putting droplets of ink onto paper, plastic, or other material.

Advantages Disadvantages

Can smudgeNot as good a qualityNeeds electricity

Easy to useCan be mass produced

Desktop PublishingMethodDesktop publishing is the making of documents using a page layout skill on a personal computer. Desktop publishing software can generate layouts and produce typographic quality text and images.

Advantages Disadvantages

Needs electricityCant take it anywhereCan be deleted easily by accident

Can be mass produced Only people who you want can see it
