Introduction

If you’re scanning documents with OCR (optical character recognit ion) applicat ions, you should us e EPSON TWAIN Pro instead of SilverFast Lite for the best results. See the electronic
TWAIN Pro User’s Guide
EPSON
for instructions.
LaserSoft® SilverFast™ Lite is a TW AI N interface program between your application software and your EPSON you scan im ages into your software. It is th e ideal interfa c e fo r s c anning photographs on any ty pe of medium: photo paper, pos it iv e and negativ e transpar encies, 35 mm slides and film, even Polaroid® media.
SilverFa s t Li te does more than transfer im ages from the sc anner—it als o lets you:
◗ Preview the im age before scanning ◗ Adjust the orientation of th e im age (such as f lip it horizontally or
vertically or rotate it)
◗ Automa tically adjust im age exposu re ◗ Make corrections to the image (such as adjusting brightness, contrast,
and tone quality)
◗ Scan mul tip le frames, mult iple images , an d even different types of
originals (c olor, graysc ale, and black and white) at one time
◗ Quickly scan Polaroid photographs (f or Spectra
automatically size the image and adjust the exposure

Basic Scanning

When you access SilverFast Lite from your TWAIN-co mpliant applica tion, you can pr ev iew and mani pulate image se ttings prior to sc anning, as described in these sections:
◗ Basic Scanning Steps ◗ Changing the Basic Settings ◗ Framing ◗ Zooming ◗ Sizing the Image
The transparency unit comes with the Professional model of the Express ion 800. It’s availab le as an option for the Executiv e and Artist models.
Basic Scanning Page 14
If you’re scanning using the optiona l t ransparenc y u nit , se e Scanning
Transpa rencies for basic scanning instructions.
If you’re scanning Pola roid photographs, see S c anning Pola roid
Photographs for in s tr uc t ions on using P olaroid mode f or quick scans.
Cropping an image makes the scanned file size smaller; the file is then faster to proces s and takes up less st orag e spac e on your hard drive.

Basic Scanning Steps

1 Access the SilverFast Lite window as described in Accessing
SilverFa s t Li te .
2 Preview the im age by clickin g t he Prescan button. Because the
prescan im age reflects what the scann ed image will lo ok lik e, it changes as you change certain settings.
3 Select the appropriate basic settings for the original you are scanning
as described in Changing the Basic Settings
4 Select the portion of the im age to be scanned.
To scan the entire original, click and drag the frame border (dotted line) to the edge of the prescanned image. To scan only a part of an image, click and drag the frame border to def ine the part of the im age you want to scan. SilverFast Lite scans only the area within the frame.

Spectra Polaroid or 600 Polaroid
When you’re scanning Polaroid photographs, you must adjus t the ex posure settin gs dif f erently than for conventionally developed photographs. These Polaroid m odes automat ic ally adjust ex pos ure and size the image area. For Polaroids taken with a Spectra camera, select Spectra Polaroid. For pictures taken with a Pol aroid 600 camera , sele ct 600 Polaroid. Se e Scanning Polaroid
Photographs for details.

Selecting the Scan Type

Select color characteristics (scan type) of the orig inal you’ll be scanning. Choose one of the following:
36 bit Color Scans using a 36-bit co lor s pace and saves a
24-bit col or im age (the def ault option)
12 bit Grayscale Scans using a 12-bit grayscale space and saves
an 8-bit black and white image with shades of gray
Not all Si lv erF ast Lite settings are available for all scan types. For examp le, t he Filter setting is not available when 1 bit Line Art (OCR) is selected.

1 bit Line Art (OCR) Saves the sc anned object as a 1-bit black and
white line art image
For information on how to scan different types of originals simultaneously, see Batch Scanning
.

Choosing the Scan Resolution

Resolution refers to how m any dots per inc h (dpi) or dots per centimete r (dpcm) you want your scanned image to contain. These sections tell you how to selec t th e best resolut ion for your image:
◗ Factors to C onsider in Selecting Res olution ◗ Changing the Resolut ion
Factors to Consider in Se lec ting Resolution
The best res olution for a sc anned image depends on the type of image you’re scanning and your final outpu t d ev ic e. T he higher a resolution you select, the larger the res ult ing image file . Fo r ex ample, an 8.5 × 11-inch original sc anned at 300 dpi can produc e a 24MB file. T he same origin al scanned at 72 dpi creates only a 1.3MB fil e. If y our scanned im age is intended only for on-sc reen viewing , yo u c an scan at 72 dpi t o reduce your file size.
Large files ta k e longer to proc es s and print, so co ns ider the prac tical limitations of your computer system and hard disk drive when selecting a resolution. To keep your file size manageable, select the lowest possible resolutio n t hat gives acceptable qualit y .
As a rule of thumb for any im age except line art, use a scanning resolutio n t hat is approxim ately one third of your output resolution. F or example , u s e a s c anning resolution up to 100 dpi wi th a 300 dpi laser printer, an d up to 200 dpi w ith a 600 dpi laser printer.
Basic Scanning Page 20
For ink jet printers, such as an EPSON St y lus s eries printer se t to 1440 dpi printin g m ode, use a sca nning resolut ion of approx im at ely 300 dpi (select a pproximately 240 dpi for 720 dpi pri nt ing mode).
For a list of re c om m ended resolutions for sp ec if ic im age types, see
Setting Up and Using Your Scanner
.
Changing the Resolution
To chang e t he resolution to a sp ec if ic s et t ing, move the re s olution slider to the left to decrease resolution or right to increas e res olution. Yo u c an also ente r a res olution in the fie ld and switch bet w een dpi (dots per inch) and dpcm (dots per centi m et er) measure m ent units.
click to switch between dpi and dpcm
If you select an appropriate resolution for your image, and then enlarge it by scaling it or selecting a larger output size, SilverFast Lite automatically increase s th e res olution proportionally so yo u don’t need to adjust the resolutio n t o retain your image quality . For example, if yo u’re scannin g a 2 × 2-inch photograph at 300 dpi and then enlarge the output s iz e t o 4 × 4-inch (a 200% enla rgement), Silv erFast Lite aut om atically scans the image at 6 00 dpi, even though the reso lut ion slider is sti ll se t to 300 dpi.
If you adjus t th e res olution to a hi gh s etting, keep th e f ollowing in min d:
◗ You’re sc anning at a reso lut ion that gives great results for photos, and ◗ You’re creating a very large file size us ing your curre nt s et ti ngs
Basic Scanning Page 21
In some instances, you may you’ll be enlarging a sm all s c anned origin al in your applic at ion program and want to retain a high image quality. In that case, you may want to select a resolution between 1200 and 2400 dpi so you can enlarge it later with good results.

to create a large file—such as when
In other instances, you may be your image. For example, if you’re enlarging an image’s size in SilverFast Lite so the s c anned file loads int o your applic at ion already enlarged, you may not need to select a s h igh a resolutio n fo r a s uc c essful scan. Your settings are c reating a file that may be slo w to p roc ess and burd ensome to your system resources.
If you move t he resolution s lider to a very high resolution fo r it s siz e, you see a mess age warning y ou that the soft w are will be “inte rpolating” the resolution you selected. This means that the software must add pixels to your imag e t o ac hieve the resolution you ch os e, but may not increase your image quality. If you see this warning message, you may want to lower the re s olution settin g.

Framing

You can adjust the frame border on your image to crop out anything on the scanner’s document ta ble that you don’t wa nt to in cl ude in your scan. You can ev en create mult iple frames on a single imag e, or f rame several different im ages, and then scan them all at once.
