  1. Process Colors The World of Color Chapter 9 Non-Designer’s Scan and Print Book

  2. Process Colors Process is a description applied to the four transparent ink colors that are combined to make full-color images.

  3. This chart shows how process colors are created.

  4. Four Process Colors Cyan Magenta Cyan, magenta, yellow and black are colors used to make up the full-color photo in the middle square. Yellow Black

  5. What are color separations? You might think that the information on the cyan plate is cyan and the magenta plate is magenta. But when documents are separated, they are actually output as black onto either paper or film. The color comes from the ink on the press; the cyan plate will be used to print the cyan ink, etc. Magenta Cyan Yellow Black

  6. Printers Loupe A loupe is a powerful magnifying glass used by printers to see the dot patterns in images.

  7. Using the loupe you can see the dots cyan, magenta and yellow that blend together to fool the eye into seeing a rainbow of colors. This illustration was produced by four-color process printing. A plate was needed for each of the colors.

  8. The pattern that is formed by color halftone images when printed in register is called rosettes.

  9. Printers Loupe Borrow and/or check-out the loupe from your teacher to complete Assignment 1.

  10. Tints of process colors A tint is a percentage of a color. The amount of tint on your screen is directly translated to the percentage of ink on the press.

  11. Adding up the inks When defining colors using process inks, you are actually sending instructions about how much ink to put on the paper. As a general rule, you don’t want to create areas with 300 percent or more of all the inks combined.

  12. Adding up the inks Keeping the amount of ink under 300 percent will make your job print better and allow the paper to dry faster. For instance you would never want to make a black color with 100 percent of all four colors (100:100:100:100). This would make a muddy mess.

  13. Adding up the inks You would only need to add about 40 percent of each of the other three inks to the 100 percent black.

  15. Check your answersAssignment 2 Matching Terms • CMYK – The four process colors cyan, magenta, yellow and black. • Color separations – The operation of separating artwork into the four process colors. The result Is four continuous-tone films (negatives or positives) which when screened are used to make printing plates. • Dot – The single element of a halftone. • Process colors – The four transparent ink colors that are combined to make full-color images.

  16. Check your answersAssignment 2 • Dots per inch (DPI) – Measuring units of image resolution; the number of dots a printing device can generate in one linear inch. It is also used to describe pixels per inch in a bitmapped image. • Tint – A percentage of a color. • Moiré – (pronounced more ray) When two or more dot screens are incorrectly overlapped; an undesirable pattern that sometimes shows up in printed images. • Rosettes – The pattern formed by color halftone images when printed in register. • Registration color – Color used on all the separations for registration.
