Study Notes
Module 1: Color
-
Human Eye: The eye adjusts when entering dark rooms using rods (120,000,000) for black and white vision and cones (6,000,000) for color vision, with variations in sensitivity for red, green, and blue light. Exceptions apply for colorblind people.
-
Objective Color Interpretation: Requires a dedicated light source (ideally 5000-5500°K), a surface capable of reflecting the light, and an instrument (like a human eye or a device) for measuring or evaluating color.
-
Color Definition: ROYGBIV represents the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
Color Systems
-
Additive: RGB colors (red, green, blue) are added together to create a spectrum of colors. Red + Green + Blue = White, Green + Blue= Cyan, Red + Blue = Magenta, Red + Green = Yellow.
-
Subtractive: CMYK colors (cyan, magenta, yellow, black) are used for printing, where colors are subtracted from white light, producing colors by combining inks. Cyan + Magenta = Blue, Cyan + Yellow = Green, Magenta + Yellow= Red, Cyan + Magenta + Yellow = Black (K)
-
Color Wheel: A graphic representation of color systems, illustrating relationships between colors.
-
Color Perception: Objective color perception depends on light conditions (5500 K or D50/D65 standard white light) and environmental factors. An important consideration is color metamerism, which may cause a matching of colors without corresponding spectral power distribution values.
Module 2: Prepress
-
Workflow: Concept design (art/design/client) -> prepress (layout prep, color correction) → print process. This step involves converting files to printable standards (e.g., print ready, PDF).
-
Prepress Services: Key services included in prepress are image manipulation, color correction, layout adjustments, and the creation of production ready PDF’s
File Formats
-
Vector: Scalable (e.g., .eps, .svg) and less dependent on resolution files. Good for graphics, logos, and illustrations but can sometimes be poor for image based files.
-
Bitmapped: Resolution dependent (e.g., .jpg, .png, .gif) and used for images like photos. Can be larger in file size but usually have a better output in a printed medium.
-
Important considerations: File resolution, color space, fonts, and the use of print-ready files.
Other Considerations
- Color Management: Necessary because digital devices (cameras, scans, monitors, printers) have different color gamuts (ranges of colors). Color management standardizes color across these devices to create consistency and accuracy, using terms like gamut, projection, and conversion.
