The Colortrac SmartLF SC Series wide format scanners are designed to scan images fast at the optimum resolution required to capture the original image detail without compromising quality. Colortrac’s SingleSensor technology and ClearView instant-on bi-directional LED illumination system produce up to 1200 dpi of uncompromising resolution. Whatever condition of the original, SingleSensor produces unrivalled accurate image scans, even if the original is folded, creased or crumpled. ClearView’s even lighting prevents shadows and creases and combined with the Colortrac’s SureDrive roller feed system, provides even pressure across the full width of the document, pushing it against the scan glass at the critical moment of capture. The Smart LF SC Series supports colour management workflows and can capture a colour gamut that far exceeds the sRGB colour spaces, used as an industry recognised standard.

The Colortrac SmartLF SC Series is ideal for boosting productivity. In addition to fast scan speeds, even at high resolution, the SC Series features the new SuperSpeed USB 3.0 and optimised USB 2.0 digital interfaces. SuperSpeed data transfer means there are fewer communication bottlenecks and you can always scan the largest documents in the greatest detail fast. after the scan. ScanOnce saves the full dpi and allows the user to zoom, pan and edit on screen. Colortrac’s ClearView LED lighting system uses instant-on low energy illumination technology and is Energy Star qualified.

Colortrac’s ScanOnce technology means no need to preview scans to adjust settings for a rescan because all editing is applied after the scan. ScanOnce saves the full dpi and allows the user to zoom, pan and edit on screen. The large staging platform makes loading documents into the scanner fast and easy. The SmartLF SC Series is designed specifically to auto-size documents face up in the centre of the scanner, which helps the operator see what they are scanning and load creased documents more effectively.

The Colortrac SmartLF SC Series includes SmartWorks EZ Touch software, TWAIN and EMC ISIS drivers. SmartWorks EZ Touch is a touch-screen optimised, copy and email software which includes image edit features and user adjustable document pre-sets. SmartWorks EZ Touch software supports TIFF, JPEG, & PDF file formats and any printer via the manufacturer’s own Windows printer driver. Colortrac’s WinSync optimises windows driver technology that allows you to easily connect Colortrac scanners to your PC.

The three configurations; monochrome, colour, and enhanced colour, are on-site software upgradable, so the Colortrac SmartLF SC Series can be upgraded quickly and easily as your requirements change.

The Colortrac SmartLF SC 42 scans up to 42 inches/106.7 cm and can take a maximum media width up to 44 inches/111.7 cm. The Colortrac SmartLF SC Series accepts media up to 0.08 inches (2.0mm) thick. The minimum media size the Colortrac SmartLF SC Series can scan is 6 x 6 inches/15.2 x 15.2 cm. Maximum image length for scanning is 96 inches (2438mm) using SmartWorks EZ Touch software (included). The Colortrac SmartLF SC 42 has a maximum of 50,400 pixels.

Colortrac SmartLF SC Series incorporates propriety technologies unique to Colortrac scanners. These technologies include SingleSensor, ClearView, SureDrive, Firefly and WinSync. Colortrac’s SingleSensor scanning is a patented technology which combines contact image sensors (CIS) in a robust, single-piece unit, enabling a significantly higher optical quality and dramatically increasing pixel alignment stability. The SmartLF SC Series has 30,000 short image-path sensors and a custom designed advanced bi-directional LED lighting system. The bi-directional lighting system, called ClearView, combines 96 to 144 extra long-life switchable red/green/blue LEDs across the full width of the scanner for optimum illumination and instant-on scanning capability. SingleSensor and ClearView work together to reduce optical errors to a minimum ensuring all scan and copy data is of the highest possible colour and dimensional accuracy. Because each sensor is on the same imaging line combined with bright, even light from the LEDs across the full width of the scanner, scans have a wide and consistent colour gamut across the full width of the document. Colortrac’s SingleSensor is colour calibrated and has a scan accuracy of +/-0.1% +/-1 pixel.

Colortrac’s SureDrive system is an innovative active pressure roller that gently presses the document against the SingleSensor. The single, full-width, motor-driven hold -up roller eliminates variations in document speed or feed inconsistencies, eliminating the possibility of misaligned data. The soft pressure roller running the full length of the SingleSensor allows the scanner to dynamically respond and actively work against the optical disturbances caused by document lift and paper creasing. Shadow effects in folds of creased documents are also reduced. This technology ensures that delicate or fragile media such as newspapers and old blueprints can be safely and accurately scanned without problem. WinSync means the Colortrac Smart LF SC Series is compatible with Windows 10, 8, 7, Vista, and XP.

Colortrac’s Firefly technology refers to the new SuperSpeed USB 3.0 and optimised USB2.0 interface. The SmartLF SC Series scanners are the first to incorporate the new SuperSpeed USB 3.0 digital interface. With a dramatic x10 increase in internal data transfer rates, the new USB 3.0 interface works at up to 5GB/sec. In terms of speed of scan data saved to the computer, this represents more than double the previous rate of 28MB/sec (USB2) to 65-85MB/sec for USB 3.0. SuperSpeed USB 3.0 is unique to Colortrac and allows the SmartLF SC Series to work at full speed using higher resolutions on wider documents. The SmartLF SC Series has enhanced USB2 circuitry which achieves a 25% improvement in data speed (35MB/sec) above the previously recognised industry average transfer rate of 28 MB/sec for a normal USB2 equipped PC. USB3 is not available with Windows XP computers so the Smart LF SC Series must be connected via USB2. Higher data transfer give the SmartLF SC Series user the freedom to scan wider and at higher resolutions without compromising productivity, making it ideal for large amounts of archiving.

The EMC ISIS driver provides fully integrated wide format scanning compatible with common industry EDC/EDM applications. The EMC ISIS driver allows basic scan settings for resolution, paper size, and simple thresholding of black and white scan data and ‘scan to cloud’ where application allows. Saved file formats depend on the host application.

Optional accessories for the Colortrac SmartLF SC Series include: a Document Return Guide, for retrieving scanned documents to the front; Floor Stand with Catch Basket; PC, Monitor, Keyboard and Mouse Mounting Kit for Floor Stand; Repo Stand; and Document Carrier Sheets. Optional software available includes SmartWorks EZ Touch Plus, an upgrade which includes more image manipulation and user control.

SmartWorks Pro SCAN & COPY is optional professional software providing more advanced controls and colour calibration, including profiled RGB, and improving all scanning and copying applications. SmartWorks Pro is ideal for batch scanning and includes auto-size and number-sequencing technology which instantly adjusts the scan according to the size of the document so you can effortlessly scan a batch of different sizes without having to adjust your settings.

As you would expect from Colortrac, reliable performance is a given. For added peace of mind, Colortrac SmartLF SC Series wide format scanners feature a 2 year next day on-site warranty.
