Various printing term definitions….

CMYK
The primary colors used in 4-color printing. CMYK are used to reproduce full color on the printed sheet. CMYK also called PROCESS COLOR.

  • C: Cyan (Blue)
  • M: Magenta (Red)
  • Y: Yellow
  • K: Key (Black)

RGB:
The additive primary colors, red, green and blue, used to display color in video monitors. Printing with a file in RGB color mode will produce a washed out appearance. I.D. designed PRINTS does not check files for RGB. That responsibility falls to the customer before submission of the files.

Coatings:
The mixture of clay materials that are applied to paper to improve the smoothness of the paper’s surface and improve ink holdout during the printing process. Examples are Aqueous coating (AQ) and UV coating. UV coating adds a gloss finish to the product and also improves the vibrancy of the printed colors.

Color Types:

  • 4:4 (4 over 4) – 2 sided :: full color on front and on back
  • 4:1 (4 over 1) – 2 sided :: full color on front, black on back
  • 4:0 (4 over 0) – 1 sided :: full color on front

Pantone Matching System (PMS):
A registered name for an ink color matching system used to compare, match and identify specific colors. To do so we use a pantone book. It contains pantone colors with their closest CMYK values.

Resolution:
The measurement of output quality expressed in pixels (dots) per inch on a computer monitor or dots per inch on printed media. For example, a monitor displaying a resolution of 800 by 600 refers to a screen capable of displaying 800 pixels in each of 600 lines, which translates into a total of 480,000 pixels displayed on the screen. When referring to printed media, a 300 dpi (dots per inch) printer for example, is capable of outputting 300 dots in a one-inch line, which means that it has the ability of printing 90,000 distinct dots per square inch (300 x 300).
