Screen printing uses stencils to transfer images onto surfaces through a fabric screen. The stencil blocks ink from passing through in some areas while allowing it in others to create the image. Carousel screen printing uses multiple screens on a rotating mechanism to print with different colors more quickly and efficiently. Screen printing is commonly used to apply graphics and logos to products. Photocopying uses a dry toner instead of liquid ink in a non-contact printing process, allowing images to be reproduced in different sizes. Gravure printing employs an engraved plate to hold ink which is applied to paper to create high-quality art and photography books. Offset lithography uses oil and gum to divide a smooth plate surface into ink-accepting and ink

1. The Printing ProcessesByChristopher

2. Screen PrintingImagery- How the image is copiedScreen printing uses stencils for transferring images onto paper or any other medium.

3. Different stencils are used for different colors.The Mechanics The stencil is supported by a fabric. This fabric allows the ink to soak through onto the medium of printing.A good example of screen printing. The open parts of the stencil allow the ink to go through the fabric and onto the paper. The image is transferred.

4. The block parts of the stencil do not allow the ink to go through the fabric and onto the paper. This creates the shape.Carousel Screen-printingThe ScreensMultiple screens

5. Each screen contains a different stencil and is inked with a different color

6. Rotated after printingBacking material placed here and is aligned with the screen.

7. Carousel Screen-printing ProcessThe use of a carousel allows production to be quicker and more efficient. This process list assumes that the machinery is set up and the screens are inked.Inked screen with stencil is lowered onto paper. The ink is transferred.Inked screen is lifted up and rotated to a screen with a different colour and shape .This is repeated until all colours and shapes have been printed.

8. Uses of Screen Printing in GraphicsScreen printing is usually used as part of a big process to create a product. Its main use is to decorate with or attach a logo to the productScreen printing is used to put the graphics on products.Screen printing can be applied when creating pieces of art.

9. Advantages and Disadvantages of Screen printing

10. Photocopying- XerographyPhotocopying involves a non-contact printing method.It uses a dry colouring method. There is no liquid ink involved. Instead it uses a powder called “Toner”Photocopying Printing Process

11. Uses of Photocopying in GraphicsBecause photocopying is a non-contact printing method it can be used to print images in different sizes. This is useful in graphics when one is working in different scales. For example, when designing a logo, it is important that the logo is readable no matter what size. So you could use the photocopier to print it in different sizes when you are in the designing stage.If you are working with black and white graphics, the photocopier can be useful in making an accurate copy of an image and print it in black and white.

12. Gravure PrintingMechanics:Gravure printing uses an printing plate engraved with the image wanted. These engravings would hold the ink that will be printed on the paper

13. Applications of Gravure Printing Because it has an engraved plate, it can be used to create high quality art and photography books. Also it can be used for expensive magazines.
