Selecting Epson Scan Settings By: Malarieco

Overview of the Epson Scan Modes

Epson Scan lets you control all aspects of scanning and includes three modes.
Full Auto Mode lets you scan quickly and easily, without selecting any settings or previewing your image. This is the default mode in Epson Scan.

Full Auto Mode is best when you need to scan documents or photos at 100% size and you do not need to preview the images before scanning. You can restore faded colors or remove dust marks by clicking the Customize button.

See Using Full Auto Mode for instructions on scanning in this mode.
Home Mode lets you customize some scanning settings and check their effects with a preview image.

Home Mode is best when you want to preview images of photos, film, or slides before scanning them. You can size the image as you scan, adjust the scan area, and adjust many image settings, including color restoration, dust removal, Digital ICE Technology (for color film and slides only), and backlight correction.

See Changing the Scan Mode for instructions on switching to Home Mode.

See Selecting Basic Settings for scanning steps.
Professional Mode gives you total control of your scanning settings and lets you check their effects with a preview image.

Professional Mode is best when you want to preview your image and make extensive, detailed corrections to it before scanning. You can sharpen, color correct, and enhance your image with a full array of tools, including color restoration, dust removal, Digital ICE Technology (for color film and slides only), and backlight correction.

See Changing the Scan Mode for instructions on switching to Professional Mode.

Selecting File Save Settings

When you see the File Save Settings window, you need to select the location, name, and format of the scanned image file you want to save.
Do one of the following to open the File Save Settings window.
Full Auto Mode
In the standby window, click the Customize button, then click the File Save Settings button. (If you started Epson Scan from a program like Adobe Photoshop Elements, this button doesn’t appear.)
Home or Professional Mode
Click the  File Save Settings button to the right of the Scan button. (If you started Epson Scan from a program like Adobe Photoshop Elements, this button doesn’t appear.)
In the File Save Settings window, specify the file folder in which you want to save your scanned image. Click the Documents or Pictures radio button, or the My Documents or My Pictures radio button.
If you want to select another folder, click Other, then click Browse (Windows) or Choose (Mac OS X) and select the folder. If you want to save your image on the desktop, simply click Other.
Specify a file name prefix with an alphanumeric character string. A 3-digit number is automatically added to the file name, but you can change the Start Number if you like. If you are scanning multiple images at once, each image will receive a different 3-digit number.
Note:
With Windows, the following characters cannot be used in the prefix.
\, /, :, ., *, ?, ", <, >, │
With Mac OS X, you cannot use a colon (:) in the prefix.
Select a file format as described in the following table. Depending on the format, the Options button may be available for making detailed settings.
Format (File Extension)
Explanation
BITMAP (*.BMP) (Windows only)
A standard image file format for Windows. Most Windows programs, including word processing programs, can read images in this format.
JPEG (*.JPG)
A compressed file format in which the compression level can be selected. The JPEG format lets you highly compress image data. However, the higher the compression, the lower the image quality. Any lost image quality data cannot be restored, and the quality deteriorates each time the data is saved. The TIFF format is recommended when modification and retouching are required.
Multi-TIFF (*.TIF)
A TIFF format where multiple pages are saved to the same file. You can also edit the scanned images before saving them. See Epson Scan Help for details. To open Multi-TIFF files, you need a program that supports it.
PDF (*.PDF)
A document format that can be read on both Windows and Macintosh systems (platform independent). To use PDF documents in Windows, you need Adobe Reader or Acrobat. Multi-page documents can be saved as one PDF file. When you save color or grayscale images in PDF, you can select a compression level. You can also edit the scanned images before they are saved. See Scanning Directly to a PDF File for details.
PICT (*.PCT) (Macintosh only)
A standard image file format for Macintosh. Most Macintosh programs, including word processing programs, can read images in this format.
PRINT Image Matching II JPEG (*.JPG) or TIFF (*.TIF)
A file format that includes PRINT Image Matching II data for enhanced quality and a wider color range. Print Image Matching II compatible printers can then print this data for brilliant, true-to-life results. (PRINT Image Matching data does not affect the way the image displays on the screen.) Available in JPEG or TIFF format.
TIFF (*.TIF)
A file format created for exchanging data between many programs, such as graphic and DTP software. When scanning black & white images, you can specify the compression type.
The checkboxes at the bottom of the window give you these options.
Overwrite any files with the same name
Select this option if you want to reuse the selected file name and location and overwrite previous files with the same names.
Show this dialog box before next scan
Select this option if you want the File Save Settings window to appear automatically before you scan (Home or Professional Mode only). If you deselect it, you must click the  File Save Settings button to open the window in Home or Professional Mode.
Open image folder after scanning
Select this option if you want Windows Explorer or the Macintosh Finder to automatically open the folder where your scanned image is saved when Epson Scan finishes scanning.
Click OK.
In Full Auto Mode, click OK again, then click Scan. In Home or Professional Mode, click Preview, then click Scan.
The scanned image is automatically saved in the file and location you chose.

Selecting the Scan Resolution

In Home Mode, you can change the resolution only if you select Other as the Destination setting.
In Professional Mode, you can select the resolution you want at any time.
Before you select the scan resolution, you should consider whether you will enlarge your images before or after you scan them. Follow these guidelines.
You will not be enlarging the images.
If you will scan the images at 100% size or smaller and will not enlarge them later, you can accept the Resolution setting selected by Epson Scan based on your Destination setting (Home Mode only).
You will enlarge the images as you scan them (increase the Target Size setting).
If you will enlarge the images in Epson Scan so you can use them at a larger size, you can accept the Resolution setting selected by Epson Scan based on your Destination setting (Home Mode only).
You will scan the images at their original size, but then enlarge them later in an image-editing program.
If you plan to enlarge your images later in an image-editing program, you need to increase the Resolution setting to retain a high image quality after enlargement. Increase the resolution by the same amount you will increase the image size. For example, if the resolution is 300 dpi (dots per inch), but you will increase the image size to 200% in an image-editing program, change the Resolution setting to 600 dpi in Epson Scan.
Click the arrow next to the Resolution list and select the number of dots per inch at which you want to scan. See the table below for some guidelines.
What you will do with the scanned image
Suggested scan resolution
Send via e-mail, upload to web, view only on the screen
96 to 150 dpi
Print, convert to editable text (OCR)
300 dpi
Fax
200 dpi
Enlarge after scanning at 100%
Increase Resolution setting by same amount you will increase image size after scanning
After selecting the Resolution, you can preview your image and make any necessary adjustments. See Previewing and Adjusting the Scan Area to continue scanning.

Previewing and Adjusting the Scan Area

Once you have selected your basic settings and resolution in Home or Professional Mode, you can preview your image and select or adjust the area of the image(s) you want to scan. Epson Scan displays the preview image(s) in a separate Preview window on your screen.
There are two types of preview.
Normal preview displays your previewed images in their entirety. You must select the scan area and make any image quality adjustments manually. This is the default preview type in Professional Mode, but you can also select it in Home Mode, if available.
Thumbnail preview displays your previewed images as thumbnails. Epson Scan automatically locates the edges of your scan area and applies automatic exposure settings to the images. This is the default preview type in Home Mode, but you can also select it in Professional Mode, if available.
Note:
Depending on your document type and other settings, the normal preview may be automatically selected and you will not be able to change to thumbnail preview.
Follow these steps to preview your image(s) in Home or Professional Mode.
Click the Preview button toward the bottom of the Epson Scan window. If you want to change the preview type, click the Thumbnail checkbox under the Preview button, if it is available.
Epson Scan prescans your image(s) and displays them in one of the following Preview windows.
Normal preview
Thumbnail preview
If you are viewing the normal preview, you can do the following to adjust the image(s).
To select your scan area, click the  auto locate icon to place a marquee that marks the edges of your image area. You can move the marquee to change the scan area. See Adjusting the Scan Area (Marquee) for instructions.
Note:
If you are going to scan at a different size than your original, you must first select your Target Size and automatically create a marquee that is proportioned to that size. See Selecting the Scan Size for instructions. You can then copy the marquee and place it on each image you will scan at that size.
To zoom in on an image, click inside the scan area and click the Zoom button. Epson Scan prescans again and displays a larger preview on the Zoom tab. (Your other images are still previewed at the original size on the Preview tab.)
To adjust the image quality, click the image(s) you want to modify and make the adjustments as described in Adjusting the Color and Other Image Settings.
If you are viewing the thumbnail preview, you can do the following to adjust the image(s).
To zoom in on an image, double-click its thumbnail, or click the thumbnail and then click the Full Size tab near the top of the Preview window. (This feature is only available when you are scanning multiple images at the same time.)
To rotate an image or flip it horizontally (like a mirror image), click its thumbnail and then click the  rotation icon or  mirroring icon.
To adjust the scan area to crop your image, you can create and move a marquee that marks the edges of your scan. See Adjusting the Scan Area (Marquee) for instructions.
To adjust the image quality, click the image(s) you want to modify and make the adjustments as described in Adjusting the Color and Other Image Settings. If you want to apply the adjustments to all your images, click the All button.
Note:
If your image is not rotated correctly, see Images Are Rotated Incorrectly.
When you have finished adjusting the scan area, and modifying the color and image settings, you can select the size of your scanned image, if you have not already selected it. See Selecting the Scan Size for instructions.

Adjusting the Scan Area (Marquee)

A marquee is a moving dotted line that appears on the edges of your preview image to indicate the scan area.
You can move the marquee, adjust its size, and create multiple marquees on one image (normal preview only) to scan different image areas in separate scan files. Follow these steps.
To draw a marquee, move your cursor over a preview image. The pointer becomes a set of cross-hairs.
Position the pointer in the area where you want to place the corner of your marquee and click. Hold down the mouse button and drag the cross-hairs over the image to the opposite corner of the desired scan area. Then release the mouse button. You see the moving dotted line of the marquee.
Do one of the following to adjust the marquee.
To move the marquee, position your cursor inside the marquee. The pointer becomes a hand. Click and drag the marquee to the desired location.
To resize the marquee, position your cursor over the edge or corner of the marquee. The pointer becomes a straight or angled double-arrow. Click and drag the edge or corner to the desired size.
Note:
To restrict movement of the marquee to vertical or horizontal only, hold down the Shift key as you move the marquee. To restrict sizing of the marquee to the current proportions, hold down the Shift key as you resize the marquee.
For best results and image exposure, make sure all sides of the marquee are located inside the preview image. Do not include any of the area around the preview image in the marquee.
To draw multiple marquees (up to 50; normal preview only), you can just draw them as described in steps 1 through 3, or click the  copy marquee icon to create additional marquees of the same size. You can move and resize all the marquees as described in step 3. To delete a marquee, click inside it and click the  delete marquee icon.
Note:
If you draw multiple marquees, make sure you click the All button in the Preview window before you scan; otherwise, only the area inside of the last marquee you drew will be scanned.

Adjusting the Color and Other Image Settings

Once you have previewed your images and adjusted the scan area, you can modify the image quality, if necessary. Epson Scan offers a variety of settings for improving color, sharpness, contrast, and other aspects affecting image quality.
Before you make adjustments, be sure to click the image or marquee for the area you want to adjust. In Professional Mode, you may need to scroll down to the Adjustments area of the main Epson Scan window.

Selecting the Scan Size

You can scan your images at their original size, or you can reduce or enlarge their size as you scan them. You do this using the Target Size setting in Home or Professional Mode.
Home Mode
Professional Mode
If you are going to scan your image to a particular size, you should select the Target Size setting after previewing it, but before adjusting your scan area (indicated by the marquee). This sets the scan area to the correct proportions so your image will not be cropped unexpectedly.
For instructions on previewing your image(s), see Previewing and Adjusting the Scan Area. Then follow these steps to select the Target Size setting.
You can choose a predefined scan size from the Target Size list. Click the arrow in the list and select the size you want. A marquee (dotted line) proportioned for that size appears on your preview image.
If you need to create a scan size that is not in the Target Size list, you can create a custom size. Click the arrow in the list and select Customize. You see the Target Size window.
Type a name for your custom size, enter the size, click the Save button, then click OK. Your new size appears in the Target Size list.
In Professional Mode, you can fine-tune the size using additional tools. Click the + (Windows) or  (Mac OS X) next to Target Size to display these tools.
To size your image by a certain percentage, adjust the Scale value.
To change the way your image is cropped, turn Trimming on or off. (See Epson Scan Help for details.)
To unlock the proportions of your scan size, click the  lock icon. Then adjust the marquee or enter new width/height measurements.
Once you have selected your scan size, you can click and drag the marquee to the area in the image you want to scan. For details, see Adjusting the Scan Area (Marquee). The marquee proportions are retained as you adjust it.
If you need to rotate the marquee for a landscape or portrait image without changing its aspect ratio, click the  orientation icon. (Not available if you are scanning at the Original Target Size.)
Note:
For more information about using the Target Size tools, click Help in the Epson Scan window.
Now you are ready to scan your image(s). Click the Scan button, and see Finishing the Scan for instructions.
