Contex is one of Denmark’s fastest growing IT companies and the world’s largest developer and producer of large format scanning and large format imaging solutions. Originally founded in 1923, the company designed and manufactured inventive, time-saving business machines, including printing machines, mechanical and electronic calculators, and electrostatic copiers, which were distributed and sold worldwide under the Rex-Rotary and Gestetner brand names. By the early 1980s, the foundation for Contex Scanning Technology began and Contex evolved into the leader of the global imaging industry in large format scanning, copying and image enhancement. The development of modular scanning technology began in 1986 and in 1988, Contex introduced its first monochrome large format scanner. Contex released a complete line of monochrome scanners in 1990 and launched its first large format colour scanners in 1996. Today, Contex offers 18”, 25”, 36”, 42”, 44”, 54”, 60 and all –in-one, colour and monochrome scanners with CIS (colour image sensors) and CCD (charged-couple device) imaging technology. Over the years, Contex scanners have received numerous awards from leading trade publications and analyst firms including Cadalyst, Wide-Format Imaging, and BERTL (Business Equipment Research and Test Laboratories). Contex provides scanning solutions in over 90 countries and is recognised by a wide range of industries for reliability, value, high-performance and superb image quality.

The Contex HD range of CCD large format scanners (HD Ultra X, HD Ultra, HD 5450, and HD iFLEX) is recommended for high productivity and top quality. The Contex HD Ultra X range of large format scanners feature advanced Charge Couple Device technology with true 48-bit colour and 16-bit grayscale workflow, 7 x 4, 5 x 4, 4 x 4, or 1 x 4 linear colour CCD’s (Red, Green, Blue and Gray), premium custom lenses from Fujifilm, and an advanced image processing algorithm, achieving superior image quality and an optical resolution of 600 to 1200 dpi and a maximum resolution of 9600 dpi. The Contex HD range of large format scanners have the ability to process the entire range of 48-bit colour data ensuring the most accurate images with Accuracy Lens Enhancement (ALE) ensures precision of 0.1% accuracy. Contex Perfect Light is the latest in LED technology to ensure the highest possible image quality. Contex CCD Scanners (except the iFLEX flatbed) feature Optomised Thickness Adjustment Control (OTAC) and All Wheel Drive (AWD) technologies. OTAC is for scanning thick originals and monitoring pressure on the surface of the document. AWD is a precision paper feed tracking system which ensures a perfectly straight scanning path and distortion-free scans. Gigabit Ethernet, xDTR2 and xDTR improves overall productivity by increasing the data transfer speed, so more image data can be sent to the PC faster.

Contex CIS range of large format scanners (SD ONE+, SD 3600, IQ Quattro 2490, 3600, and 4400) feature a number of advanced Contex proprietary technologies to achieve superb image quality and reliability. The Contex Colour Imaging Sensor technology feature fourth generation CleanScan CIS technology combined with CFR, SIGMA and xDTR to ensure the highest quality CIS scanners in the market. Contex CleanScan CIS technology is based on custom CIS modules with dual-sided LED light and Dual Diffusion, which suppress shadows and unwanted backgrounds. The patented Contex Colour Fringe Removal (CFR) technology is an advanced filtering technology, producing superior image quality with excellent lines. Signal Intensity Matching (SIGMA) is a Contex patented technology that minimises sensor differences live during a scan, to adjust for differences in sensor heating. xDTR improves overall productivity by increasing the data transfer speed of the USB interface, so more image data can be sent to the PC faster. This means a larger document (and more documents) can be scanned at higher resolutions without waiting for data transfer to complete.
