IMAGE ADJUSTING FUNCTION

When printing a color image in grayscale, text and lines that are drawn in faint colors are printed in black. This function allows you to bring out color text and lines that are faint and difficult to see when printed in grayscale.

Windows

1. Click the [Image Quality] tab.
2. Select the [Text To Black] checkbox and/or the [Vector To Black] checkbox so that appears.
• When [Text To Black] is selected, all text other than white text is printed in black.
• When [Vector To Black] is selected, all vector graphics other than white lines and areas are printed in black.

Preset settings are available in the machine's printer driver for various uses.

Graphics mode	Select the graphics mode from "Raster" or "Vector".
Bitmap compression	The data compression ratio of bitmap is set. If the ratio is higher, the image quality becomes lower.
Screening	Select the screening to modify the image to suit specific preferences, according to the appropriate image processing method.
Sharpness	This setting creates a sharper image with clear outlines, or smooths the image for a softer effect.
Smoothing*	Resolution enhancement techniques (RETs) are used to smoothen the outlines of images. This setting processes the image to increase the resolution and smooth jagged image borders.

* This function is available in a Windows environment.
