  1. THE THEORY & CONCEPTS Lesson 1 – Part 1

  2. What is Graphic Design • It’s a CREATIVE PROCESS • Undertaken in order to convey a specific message/s • I can’t teach you to be Creative but I can give you some tips of the various Processes involved. • What comes to your mind?

  3. Image file formats (some of them) • There are two types: • Raster (pixels) • Vector (lines) • There are also two types of compressions: • Lossless • Lossy

  4. Raster Formats (1) • JPEG (Joint Photographic Experts Group) • Lossy compression • Extention is .jpeg or .jpg • JPEG files suffer degredation when repeatedly edited and saved • Does not support Transperancy

  5. Raster Formats (2) • PNG (Portable Network Graphics) • The successor of GIF (256 colours dohh) • Lossy or Lossless formats • Supports gamma and chromaticity data (transperancy) • TIFF (Tagged Image File Format) • Can be Lossy or Lossless (we usually tend to use it cos the Lossless version is very good and relatively decent filesize)

  6. Raster Formats (3) • BMP (very large file size since it saves itself as uncompressed) • JPEG 2000 • GIF • PSD (Photoshop)

  7. Vector Formats • As opposed to raster formats, vector formats contain a geometric description • At some point all vector graphics must be rasterized to be displayed or printed • AI • EPS (Encapsulated PostScript) • PDF

  8. What Resolution? Size? Pixels?

  9. What Colour Model? • CMYK or RGB? • Is it for the screen or for print? • CMYK (subtractive) colour model is used for the printing process and refers to the four inks used – Cyan, Magenta, Yellow and Key

  10. What Colour Model? (2) • RGB (additive) colour model colour model used to display images on an electronic system – Red, Green, Blue.
