Quality tab in the job parameters window 235 Parameter Screening Option Screening Image halftone screen Description Converts images, graphics and text into information that can be printed (halftone dots). The human eye smooths out this information, which seems visually consistent with the original picture. Thus, the more lines per inch, the more natural the image appears. Screening is achieved by printing dots in numerous shapes or lines in an evenly spaced pattern. The distance between the screen dots or lines determines the quality of the image. Printers can work with constant amounts of toner and still produce a wide range of colors when you use screening. The darker the color, the larger the dot. To print an image on a digital printer or press, the Creo server needs to digitally approximate the grayscale values with different distributions of pixels. This process is commonly referred to as halftoning. Digital halftoning begins by sampling the original image at the same number of dots per inch as the printer and constructing digital halftone cells. Provides the following options: Note: If you select the Dot 2, Line 1 or Line 2 options for a job that will be printed, make sure that you also select Permission in the Image Quality Setting screen on the printer's touch panel. ● Dot 1-Applies a high dot-type screen ● Dot 2-Applies a medium dot-type screen ● Line 1-Applies a high line-type screen ● Line 2-Applies a medium line-type screen ● Stochastic-Stochastic screening differs from conventional halftone screening in that high ink density results in more dots, not bigger dots. Low ink density produces fewer dots, not smaller dots. As stochastic screening involves millions of minuscule dots, many more than are used for conventional halftone screening.
