Introduction

Features

The CD-ROM that comes with your scanner contains the EPSON
scanner software suite, including EPSON TWAIN Pro and
TWAIN Pro Network (The network version of EPSON TWAIN
Pro). The software suite is the perfect companion for your EPSON
scanner. Using your scanner and the software from the CD-ROM,
you can scan images in color, grayscale, or black and white, and
save them as files or print them out. Other software such as
EPSON Scanner Monitor and PageManager for EPSON support
the Start Button feature to make scanning much easier. EPSON
Scan Server allows your scanner to be used over a network.

The software supports the following EPSON scanners:

❏

EPSON Expression 1600/1600Pro

EPSON TWAIN Pro and EPSON TWAIN Pro Network

❏

directly control all of the features of your EPSON scanner.
This program is the standard cross-platform interface for
other applications.

The CD-ROM also contains other applications that let you use
your scanner in exciting new ways. For detailed information, refer
to the supporting documentation.

EPSON Scanner Monitor allows your scanner to access

❏

software that supports the Start Button feature.

EPSON Screen Calibration utility allows you to calibrate your

❏

scanner and monitor to reproduce images identical to the
originals.

Introduction

1

PageManager for EPSON is TWAIN-compliant software that

❏

supports the Start Button feature. This feature allows you to
scan and send data to a target application with a single push
of the Start button. For more information on PageManager,

❏

Chapter 2 provides a complete description of EPSON TWAIN

❏

Pro and TWAIN Pro Network features. Refer to Chapter 2
when making scanning settings.

Chapter 3 explains how to calibrate your monitor to match

❏

your EPSON scanner. If you notice that colors on your screen
or in your printout do not match the original image, see this
chapter.

Chapter 4 contains troubleshooting information. If your

❏

software does not operate properly or scanned images are not
what you expect, see this chapter.

Notes

Applying a Preset Tone Curve

You can finely adjust the contrast within an image by applying
one of the preset tone curves. This allows more control over the
image when used in conjunction with the Auto Exposure settings
in the Image Controls dialog box. The tone correction list in the
Tone Correction dialog box provides the six most common tone
correction curves, described below.

Linear

A linear tone curve has no tone correction. Use this setting if you
are satisfied with the tone of the preview image.

slider.

.

3. To change the gray balance intensity level of the color you
selected, move the slider left or right, or enter a value in the
text box.

You can enter a value between 0 and 100. Changing the value
causes the color in the right hand box to change accordingly.
Your changes are also reflected in the image in the Preview
window.

Note:

See “Color Adjustment” on page 2-32 for more information on
adjusting the gray balance intensity level.

1-14

Scanning Basics

Adjusting the Saturation Setting

Saturation is the density of a color. Higher saturation makes the
color appear richer, while lower saturation makes it appear paler.

To change the saturation level of the image, move the
slider left or right, or input a value in the text box.

You can enter a value between -100 (lowest color density) and 100
(highest color density).

Note:

See “Color Adjustment” on page 2-32 for more information on adjusting
the saturation level.

Using the Tone Curve

The tone curve provides you with a versatile means for adjusting
the intensity of the colors of the image being scanned. You can
adjust the shadow, mid-tone, and highlight values, which helps
to ensure well-balanced coloring of the image.

Use of the tone curve is recommended for fine adjustments after you
have previewed the image and adjusted the highlights and the

Channels

Click an option button under channels to select the color whose
tone curve you want to adjust. When the master channel at the
top is selected, your adjustments affect all three colors. Selecting
one of the other channels allows you to adjust red, green, or blue
only.

Tone curve editor

Moving the mouse pointer into the tone curve editor causes it to
change to a finger. Use this pointer to drag any of the five points
in the curve and change its shape. The x-axis of the curve is the
brightness of the original (input values) while the y-axis is the
brightness of the scanned image (output values).

To change the tone curve back to its default, select
tone correction list.

Output values

These are the current values for output data in accordance with
the current locations of the points inside the tone curve editor.
These values change when you drag points in the tone curve
editor, or you can enter in values here to change the shape of the
tone curve. Each value can be adjusted within the range of 0 to 255.

Note:

❏

Each output value name has a check box to the left of it. Highlight
and Shadow are always selected, but you can select or clear 1/4 Tone,
Midtone, and 3/4 Tone by clicking their check boxes.

❏

When a value’s check box is clear, its point on the tone curve editor
automatically shifts to smooth out the tone curve when one of the
other points is moved.

❏

When a value’s check box is selected, it means that its point is fixed
and it will not shift when other points are moved.
