The SmartLF Gx+ 28 is
perfect for capturing
sharply defined detail
on technical drawings
and maps ...
... as well as vibrant,
accurate colors for
graphics professionals.
SmartLF Gx+ 28 large format scanners have all the advantages of CCD technology's superior color imaging - the ability to scan a wide gamut (range of colors) and a high dynamic range (ability to see detail in dark and light areas) - combined with 1200 dpi optical resolution, the highest optical resolution available in any CCD scanner in the large format scanner market today. This makes them perfect for capturing vibrant, accurate colors for graphics professionals as well as sharply defined line detail on technical documents and maps.
SmartLF Gx+ 28 scanners use an Advanced 2+3 wheel-drive Active Paper Transport (APT) system that maintains accurate document positioning as the document passes through the scanner. Combined with bright white bi-directional LED illumination, APT means that even folded documents scan accurately and shadow free.
Images are scanned using 48-bits (color) or 16-bits (monochrome), with the best 24 and 8-bits selected as image data respectively.
Traditional CCD wide format scanners have superior color imaging but are disadvantaged by their fluorescent lighting systems. By using white LEDs instead of fluorescent tubes, the SmartLF Gx+ 28 large format scanner is able to maximize the benefits of CCD while saving time and energy.
No warm up, no waiting
While a fluorescently lit scanner can be used within five minutes of switching on, you need to let it warm up for about an hour in order for the tubes to reach their optimum light intensity and for the tube temperature to reach equilibrium. If you do not do this, color and stitch inaccuracies may result.
The SmartLF Gx+ 28's white LED illumination produces high quality color, just like fluorescent illumination. However, because LEDs operate with a stable light spectrum from switch on (cold) through hours of use (warm), you do not have to wait for them to warm up before you can use the scanner to best effect. Simply turn it on and scan!
Significant power saving
The SmartLF Gx+ 28 wide format scanner uses nearly 30% less power when scanning and 94% less power when idle. It has a programmable timer that will switch the unit into power saving (ENERGY STAR®) mode when it is not operated for the defined period.
In addition, its instant-on capability means that you can leave it switched off most of the time and only turn it on when you need to use it.
Light for life
While you would normally expect to replace fluorescent tubes every year or two, LEDs are long life. Unlike fluorescent tubes, which stay on the whole time the scanner is switched on, LEDs only come on during the actual scanning process. They have an estimated working life of 50,000 hours which equates to six years of constant 24/7 scanning!
Less calibration
Fluorescently lit large format scanners require more frequent calibration because the tubes age and change characteristics over their life. LEDs maintain consistent output.
No mercury
Unlike fluorescent tubes LEDs do not contain mercury, which makes them more environmentally friendly.
The SmartLF Gx+ 28 wide format scanner has four CCDs across the scan width to minimize geometric distortion, more than any other similarly sized scanner.
Traditional CCD scanners are prone to stitch and accuracy issues caused by sensor misalignment.
These are minimized in the SmartLF Gx+ 28 by housing the four CCDs within a rigid monocoque camera chassis.
High productivity
Fast scanning speed
Along with the Gx+ 42, The SmartLF Gx+ 28 large format scanner is Colortrac's fastest scanner to date. All models scan monochrome at 12 inches per second (200 dpi). If you need high volume color scanning, choose the express color e model which scans color at 4 inches per second (200 dpi).
Gigabit Ethernet connectivity
The SmartLF Gx+ 28 wide format scanner is networkable - it has a Gigabit Ethernet connection as well as a USB2 connection. Gigabit Ethernet transmits data between the scanner and the PC faster than USB2. It also allows you to place the scanner further from the host PC or network socket than USB2.
"Scan-it-once" philosophy
(Requires SmartWorks Pro software, not included with scanner.)
With other wide format scanners you have to perform multiple pre-scans of selected image areas to get scan settings right. With the SmartLF Gx+ 28 large format scanner and SmartWorks Pro software you scan only once, then perform thresholding and image enhancements on the scan in real time.
Scan-it-once technology gives you a huge workflow advantage. You can perform quality assurance and adjustments in-line, "right-first-time", instead of needing to re-scan quality control failures off-line after batch scanning is completed.
An additional advantage of scan-it-once technology is that it minimizes document movement (and possible wear) through the scanner and document skew caused by back and forth "checking".
Intelligent Adaptive Thresholding (IAT)
IAT allows you to create better quality scans of dirty documents more quickly. The free SmartWorks EZ software supplied with the SmartLF Gx+ 28 wide format scanner has three IAT settings; SmartWorks Pro software (not included with the scanner) has comprehensive IAT that you can set in real time using slider bars.
The SmartLF Gx+ 28's Advanced
Active Paper Transport looks
after your documents.
The SmartLF Gx+ 28's Advanced Active Paper Transport (APT) applies the minimum force necessary for preserving delicate originals, while achieving the required traction and accuracy to ensure images are sharp and shadow free.
We have even managed to feed newspaper through the SmartLF Gx+ 28 wide format scanner without using a document carrier sheet - you can't say that about many large format scanners!
Easy, competent included software
The supplied SmartWorks EZ software is designed for operation by non-specialist users and is very simple to use while providing all the basic scan to file and scan to copy functionality you need.
Simple scanner interface
You can access all main functions from a simple to use control panel on the scanner, which includes buttons for Scan, Copy, Stop, Rewind and Forward.
Plug 'n' Play USB2 Interface
Simply plug the scanner into your PC and use it.
The SmartLF Gx+ 28 requires minimal service and calibration. The utility software included with it provides you with all the maintenance applications you need to keep your large format scanner in prime condition and up-to-date with the latest firmware and drivers. The scan glass is held down by magnets for quick and easy removal or replacement and there is easy access to the SmartLF Gx+ 28's paper feed for cleaning.
The SmartLF Gx+ 28 wide format scanner is RoHS compliant; energy efficient (it has earned the ENERGY STAR®); does not use consumable fluorescent lamps which contain mercury; uses recycle friendly components; and is optimized for quiet operation.
The SmartLF Gx+ 28 large format scanner is available in three models: m (monochrome), c (color) and e (express color).
If your initial requirement is for a monochrome wide format scanner only, you can buy a monochrome scanner now and upgrade to color if and when you need it. If your initial requirement is for infrequent color scanning, you can buy a color wide format scanner now and upgrade to a faster express color model should your color scanning volume increase.
You can upgrade your scanner quickly and easily, by email. There is no need for you to return the scanner to us or for a service engineer to call.
