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, 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 saving 
them. See Scanning to a PDF File on page 172 for details.
PICT (*.PCT)
(Macintosh 
only)A standard image file format for Macintosh. Most Macintosh programs, 
including word processing programs, can read and prepare 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 using this data for brilliant, true-to-life results. (PRINT 
Image Matching data does not affect the way the image displays on a 
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.

Selecting the Scan Resolution
In Office Mode, you can select the resolution you want at any time.
In Home Mode, you can change the resolution only if you click Other radio button 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 the 
images before or after you scan. 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 original and 
destination settings. (Home Mode only)
 
						

							Scanning148
❏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 original and 
destination settings. (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 
by 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.
After selecting the Resolution, you can preview your image and make any necessary 
adjustments. See Previewing and Adjusting the Scan Area on page 148 to continue 
scanning.
Previewing and Adjusting the Scan Area
Once you have selected your basic settings and resolution, 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.
❏Full-size 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 Office and Professional Mode, but you can also select it in Home Mode, 
if available.
