Dot 190 which is set as default is recommended if you do not need to change the screen.

Types and characteristics of screens
This machine draws images using screens (halftone dots), and therefore the expressions for images can change with the screen type.
If an image is difficult to reproduce using the current screen (or auto selection), it is important to select the appropriate screen. When printing, there are three screen types to choose from: [Screen 1]/[Screen 2]/[Stochastic]. However, the screen assigned to each screen type can only be set by the administrator from the [Administrator Setting] menu.
There are three screen types: "line screen," "dot screen," and "stochastic screen," which are defined according to their shapes and expressions. Multiple screens with different dot/line count are available for each type.
Screen Types and Their Characteristics:
Screen Type | Characteristics | Selection Group |
|---|---|---|
Line screen | Uses many halftone lines, like scanning lines of a television, and thus provides fine quality in reproducing the gradation in images. However, text originals may not be reproduced clearly in this method, being processed in the same way as photo originals. | Screen 1, Screen 2 |
Dot screen | Uses dots to reproduce an image. Commonly used in offset printers. | |
Stochastic | Reproduces images with fine non-periodic dot arrangement using the error diffusion method. This method is suitable for reproducing text originals sharply. | Stochastic |
