Lambda HS Series
Lambda HS Series (Lambda 131 HS-Turret, Lambda 131 HS, Lambda RS) Key features
Lambda 131 HS-Turret
The Lambda 131 is the top of the line ver- sion featuring a 5-position paper turret for the unexposed media (paper, backlit, clear film, flex media) or different media widths or surfaces from 50.8 cm (20 in.) up to 127 cm (50 in.). This allows very fast access to the required media without the need to physically load and unload it. You can handle mixed orders or calibrate a new emulsion without slo- wing down or interrupting production. The requested media is menu-selected from the computer (Autoload-Function) and the turret will automatically move into the right position and start with the exposure with almost no media waste.
Lambda 131 HS
The Durst Lambda 131 Large Format Digital Laser Imager offers exactly the same fea- tures as above with the only difference of a single position instead of the 5-position paper turret. It is fully upgradeable to a Durst Lambda with 5-position paper turret.
Lambda RS
Version for Direct Digital Remote Sensing All Durst Lambda versions can be factory- adjusted to meet the exacting standards of the Geomatics community. The Durst Lambda RS Imaging Technology for Remote Sensing, Aerial Photography and Cartography offers the highest sizing and geometric precision of plus or minus 0.03 %, corresponding to plus or minus 0.4 mm (millimeter) over a writing area of 127 x 127 cm (50 x 50 in.). The unique and patented Durst Lambda continuous roll to roll single beam, 3-laser (RGB) exposure system offers total size flexibility and achieves an image qua- lity which is superior to all large for-
mat printers - photographic, inkjet and electrostatic. The Durst Lambda exposes digital information (raster pixel) directly to conventional photographic media at full continuous tone with a linear writing speed of up to 65 cm (26 in.) per minute with the choice of two resolutions of 200 and 400 ppi (equal to an apparent reso- lution of 4000 dpi). The Lambda produces images with the highest possible resolution (68 billion colors) and with a radiometric repeatability of 0.025 D per color.
Direct digital printing with unsurpassed image and text quality
Durst Lambda Series combine the advan- tages of classical silver halide photography with the potential of the latest laser and digital technology, without an intermediate film stage - and without the compromises of CMYK output, This technology offers superior color saturation and fidelity, bet- ter image quality, more details and sharper type than other alternatives (customer statement). It also provides a number of advantages over conventional enlarge- ments, including improved image quality with no image distortion and no loss of image sharpness, perfect edge to edge sharpness and evenness, a reduction in time spent handling images, and a decrease in the cost of materials. The Durst Lambda Series operate with a full 36-bit RGB color space (68 billion colors) to ensure excellent control over the light source and to produce faithful color reproductions.
Sharp images, text and graphics with exceptional details at full contrast
The Durst Lambda Digital Imaging Techno- logy ensures a constant pixel size and in- tensity over the entire image. The patented Durst continuous roll to roll laser exposing system ensures no parasite light during the exposure for perfect image white and highest contrast range.
Apparent resolution up to 4000 dpi
The Durst Lambda series feature a dual, autoswitchable resolution of 200 and 400 full continuous tone pixels per inch (ppi) with on-the-fly pixel interpolation. The 400 ppi full continuous-tone resolution of the Durst Lambda Series is comparable with a resolution of 4000 dpi of printers with half-tone dots.
High output speed
Exposes all media with the same high linear speed of up to 65 cm (26 in.) per minute. Compared with other digital systems the Lambda is "remarkably faster" (approx. 40 prints 100 x 130 cm/40 x 50 in. per hour).
Print production without size limitations
Thanks to the patented, continuous roll to roll exposure system with perfect edge to edge sharpness and evenness, the Durst Lambda have no print size limitations it can virtually generate any print size from icons to large murals (with auto- and custom panelling functions). One seamless print can be as long as one entire 127 cm (50 in.) roll (50 m/164 ft). Print sizes exceeding the max. paper width are automatical- ly divided-up and exposed in sections. Operator can select how oversized panels are split. The desired overlap is adjustable. This allows you offer new print sizes, create new and exiting products and to enter new market segments.
On-the-fly image corrections and pixel interpolation
All image sizing and image corrections, such as color, density, contrast, sharpening as well as cropping is done on-the-fly wit- hout any additional computing time.
Sharp images, text and graphics with exceptional details at full contrast
The digital imaging technology ensures a constant pixel size and intensity over the entire image. The patented Durst conti- nuous roll to roll laser exposing system ensures no parasite light during the expo- sure for perfect image white and highest contrast range.
All in one & Fully automatic take-up system
The unique size flexibility does no longer require to split the orders because of dif- ferent print sizes. With the Durst Lambda you can handle all print sizes for one order with the same device with perfect color and density match and reduced production costs.
Large customer base and high customer satisfaction
With close to 1000 units sold worldwide (as per End of July 2006), the Durst Lamb- da has the highest install base of all large format digital photo printers. In addition, more than 80 customers have multiple units up to 5 Lambda in the same location and lab chains have up to 20 Lambda run- ning successfully, which confirms the high customer satisfaction. Durst Lambda has become quickly a new industry standard for high-end large for- mat printing. It has rapidly gained a repu- tation for high productivity and flexibility, producing the finest quality of small and large format reflective and backlit prints from digital files.

Software features
On-the-fly Image Processing
Proprietary Linux-based Durst user softwa- re with patented on-the-fly image proces- sing for very fast and reliable production with minimum hard disk usage (on-the-fly pixel interpolation/scaling, color, density, contrast, saturation and sharpening cor- rections, color to black and white conversi- on, cropping, etc.). This feature completely eliminates the need to create additional printing files and therefore drastically reduces the overall printing time providing very fast operation with minimum hard disk usage. In addition, it allows to print any size print at maximum resolution and does not require re-ripping of the file in case of changes are applied. Due to this unique feature the Durst Lambda offers an unmatched real net productivity of up to 49 sq.m/hr. or 540 sq.ft./hr.
Easy and fast media calibration
The Durst Lambda features an extremely easy-to-use calibration system with a digital test image. Even with extreme devi- ations a new paper type can be calibrated in approximately three passes. Operation is limited to just three steps:
- Exposure of the test print
- Reading of the test print with the optional on-line densitometer (automatically)
- Automatical calculation of the corrections (new calibration values) by the system.
Master channel
The paper channel calibration values can be quickly adjusted to any chemical drifts via the master channel.
| Autonesting*
For optimum media use and fast printing this feature allows to automatically print different files and different print sizes side by side. |
Batch processing
For very fast operation of documents with multiple pages or print runs. |
Multiple Printing
Print runs are automatically and on-the-fly duplicated (cloned) and printed side by side for fast operation, minimum disk space and optimal use of large paper widths. |
Dual, autoswitchable resolution of 200 and 400 ppi
Durst Lambda features a dual, auto- switchable resolution of 200 and 400 continuous tone pixels per inch (ppi) with on-the-fly pixel interpolation. The 400 ppi continuous-tone resolution of the Durst Lambda is comparable with a resolution of 4000 dpi of printers with half-tone dots.
The Durst Lambda ASCII file solution offers the following advantages:
- Total flexibility for each file in terms of print size, package, color and density correction, contrast and saturation correc- tions, etc.
- Automatic image scaling: depending on the selected print size, the Durst Autospoo- ling software will automatically scale the files to fit.
- Only one hot folder necessary, as the resolution is listed in the ASCII file
- Files are no longer copied into the hot folder. Instead of that, the ASCII file con- tains the complete image path where the file is located (can be any network-connec- ted Win or UNIX station) and the Lambda will automatically pick it up from there for printing, but the original file will always stay there. This allows a very fast operation and reduces copying and network traffic.
- All files you scan or capture with a digital camera can immediately be stored on the final archival computer/hard disk/RAID, etc.
- Allows you to automatically add logos, signatures, texts or graphics on 6 selectab- le locations (Photos with logo of photo- grapher, Christmas cards, greeting cards for other occasions, image with special borders, anything you can create with Pho- toshop, Illustrator, etc and saved as TIFF).
