Title: Develop an understanding of color theory and color terminology


1
Incorporating Color Techniques Using Color and
Print
INTRODUCTION
  • Develop an understanding of color theory and
    color terminology
  • Identify how to measure, displays and prints
    color
  • Learn which colors can be reproduced well and
    which ones cannot

2
Color Modes
INTRODUCTION
  • Displays and prints images using specific color
    modes
  • A mode is the amount of color data that can be
    stored in a given file format

3
Color Models
INTRODUCTION
  • A color model determines how pigments combine to
    produce resulting colors
  • Standard color models as the basis for color
    modes

4
Image Characteristics
INTRODUCTION
  • An image is a bitmap
  • A geometric arrangement of different color dots
    on a rectangular grid
  • Each dot is called a pixel
  • Represents a color or shade

5
Understanding Resolution
INTRODUCTION
  • Bitmapped images are resolution-dependent
  • Highly magnified bitmapped images can lose detail
  • Images with high resolution show more detail and
    more subtle color transitions

6
Work with Color to Transform an Image Working
with Color Models
LESSON 1
  • Color using models of color modes
  • A gamut is the range of displayed color

Lab
RGB
CMYK

Color Psychology
LESSON 1

Color Models
LESSON 1
  • Four color models
  • RGB Mode (desktop top)
  • CMYK Mode (printing)
  • Lab Model (luminance (lightness)
  • HSB Model (Hue, Saturation, Brightness)
  • A color mode is used to determine which color
    model will be used to display and print an image

9
RGB Mode for desktop printers
LESSON 1
  • Red, Green, Blue
  • Most colors in the spectrum can be represented by
    mixing various proportions and intensities of
    Red, Green, and Blue colored light

10
More on RGB Mode
LESSON 1
  • RGB colors are Additive colors
  • Additive colors are used for lighting, video, and
    computer monitors
  • Color is created by light passing through red,
    green, and blue phosphors

11
RGB
  • The computer monitor uses RGB mode
  • RGB value of 0 White
  • RGB value of 255 Black

12
CMYK Mode four color printing
LESSON 1
  • Cyan, Magenta, Yellow, Black
  • Based on the light-absorbing quality of ink
    printed on paper
  • Colors are partially absorbed as the ink hits the
    paper and then partially reflected back to your
    eyes

13
More on CMYK Mode
LESSON 1
  • CMYK colors are Subtractive colors
  • The absence of cyan, magenta, yellow and black
    creates white
  • When combined, cyan, magenta, and yellow produce
    black

14
More on CMYK Mode
LESSON 1
  • CMYK mode is used in four-color process printing
  • Convert an RGB image into a CMYK image to produce
    a color separation
  • The computer monitor uses RGB mode so the exact
    CMYK colors are apparent only upon printing

15
Lab Model
LESSON 1
  • Based on one luminance (lightness) component and
    two chromatic components
  • Largest number of colors available with greatest
    precision
  • Create all colors contained by other color models
  • Device-independent colors will not vary,
    regardless of hardware

16
HSB Model
LESSON 1
  • Based on the human perception of color
  • HSB stands for Hue, Saturation, Brightness
  • HSB model can be used to define a color on the
    Color palette or in the Color Picker dialog box
  • HSB is not offered as a choice for creating or
    editing images

17
Hue in the HSB Model
LESSON 1
  • Color reflected from or transmitted through an
    object
  • Hue is expressed as a degree
  • Each hue is identified by a color name (e.g., red
    or green)

18
Preparing for Commercial Printing
  • Consult the printer early
  • Pre-press work allows the printer to verify the
    availability of fonts and linked graphics, make
    color corrections or separations, and set final
    printing options

Using the Pack and Go Wizard
  • The Pack and Go Wizard lets you package all the
    fonts and graphic images in a publication
  • Compress files
  • Embed fonts
  • Can take the file to another computer

21
Postscript files
  • Can create the document in postscript file
