EPSON Advanced Scanning Technologies

are being continually developed to

provide the ultimate in text sharpness,

perfect focus and colour accuracy. You

can be sure that every Perfection,

Expression and GT Series scanner has

been built to offer the ultimate

performance at every stage of the

scanning process.

Leading the way in

scanning technology

Superior film and transparency

scanning

Dynamic Range Control is another

unique EPSON development, a

professional-standard technology that is

particularly effective in transparency

scans, but also ensures the best printed

or negative film scanning by taking into

account different dynamic ranges. The

result is improved overall quality with

particular improvement in shadow detail

in dark-coloured areas

EPSON MatrixCCD™ Technology

with On Demand Pixel Optimiser

The majority of the EPSON Scanner range

features EPSON’s cutting edge alternate

MatrixCCD™ technology, which utilises a

staggered array of sensors to collect

information which is then merged into

a single line to effectively double the

scanning resolution.

This is carried out by the high

performance image processing ASIC

(Application Specific Integrated Circuit)

which also assures virtually instantaneous

image display and reduces the load on

your computer, allowing it to perform

other tasks while data-intensive

high-resolution scanning is in progress.

At low resolutions, the On Demand Pixel

Optimiser allows ultra high speed

scanning by only utilising one line of

pixels, which reduces the time taken to

read the colour information as the head

moves down the scanning bed.

Excellent Text scanning

Text Enhancement Technology ensures

maximum text recognition, even when

documents feature coloured backgrounds,

have diagrams behind the text or are

printed on thin media which can ‘show

through’ printed information from the

reverse side. This is further enhanced by

Automatic Area Segmentation, which

separates text and photographic elements

of a document, processing each at

optimum settings to ensure the sharpest

text whilst maintaining subtle gradations

in images.

Colour Quality

EPSON scanners are capable of high

quality colour processing, with the

Expression 1680/PRO achieving up to

48-bit processing, recognising over 281

Trillion colours and 65,000 shades of

grey.

This is combined with colour matching

for industry standards including Windows

ICM, sRGB and Mac ColorSync to provide

a scanned image which retains all the

colour depth and accuracy of the original.

Also, simultaneous RGB scanning ensures

superior colour fidelity by continuously

capturing and processing Red, Green and

Blue data as the scan head advances.

High resolution, high

performance

EPSON’s high quality, large diameter,

precision optical lenses are quality

controlled to ensure superior sharpness

and clarity, and work seamlessly with

EPSON Micro Step Drive - an exclusive

development which advances the scan head

in tiny, highly controlled increments – to

ensure consistent quality throughout the

entire length and width of your scans at

optical resolutions from 600 x 2400dpi to

1600 x 3200dpi.
