■Quality Tab

Specifies the resolution, halftoning method, brightness, and contrast settings.

Resolution lets you specify the printer’s resolution in dots per inch (600,300).

Halftones is the process of converting a greyscale image to black dots and white (unprinted) dots that simulate the grey shades in the original image. Different halftone patterns give different grey shade results.

Brightness is the relative proportion of light and dark areas. Decreasing brightness darkens the overall image; increasing brightness lightens it. Brightness is expressed as a relative range from -80% to +80%.

Contrast is the degree of difference between the lightest and darkest areas of an image. Decreasing contrast lightens the dark areas and darkens the light areas; increasing it darkens the dark areas and lightens the light areas. Contrast is expressed as a relative range from -80% to +80%.
