Much is possible with a Durst Epsilon Plus. In addition to the high quality prints of any size, the well-versed multitalent of Durst also handles special tasks, such as the printing of advertising panels, backlit images, albums, brochures, etc. The material utilized varies according to use and includes all RA4 photographic papers and transparent materials in different models and sizes.

Tradeshows/Advertising
Large format images in photo-realistic quality bring colors and presence to trade shows, meetings, conferences, seminars, etc.

Paneling
Advertising panels that grab the attention and are resistant to environmental influences are also covered by the Durst Epsilon Plus. Resistant, non-fading RA4 materials, such as paper, flex, trans, and clear, can be printed upon.

Backlighting
Whether at trade shows, exhibitions, or in public places: a professionally set up light box is always at the center of attention. The transparent material makes possible image reproductions with optimal luminous power and a long duration.

Photo albums
The Durst Epsilon Plus provide services worth seeing, even with the printing of photo albums, travel albums, wedding albums, and more. Thanks to the digital image processing, no limits are posed in the creativity of the layout. The high color quality makes sure that the value of these works does not fade through the course of the years.

Epsilon "LED prints" are images with a resolution of 254 ppi continuous tone, which corresponds to 1,250 dpi with an inkjet print, uniting advantages of traditional photography (large color space, favorably priced basic materials, infinitely-variable color palette, three-dimensional representation perception) with the advantages of digital image processing. Small and large photos are exposed directly from the file on conventional photographic materials without the time-consuming detour of a negative.

The Durst Epsilon Plus offers the greatest flexibility in the processing of different image formats. Images can be produced without limitation on size, from the smallest scale of an illustration to the largest format poster (with automatic division into panels). With user-friendly software, image sectors, PG series, package prints, and panorama pictures are optimally positioned and exposed on the production medium.

Your advantages

• Compared to the previous system, image detail reproduction and the overall image appear much sharper than before
• This is specially visible on smaller print sizes and in case an image contains fine details. This new image definition is comparable with a Lambda print produced at 200 ppi.

Fiber optics
The eyes of bees are composed of approximately 9,000 facets or lenses. In fractions of a second, they capture images and transfer them over the nerve fibers to the brain, where the individual images are reassembled into a total image. The glass fibers of the Durst Epsilon Plus have similar functions – they transfer the light of the LEDs punctually and per color onto the photographic paper and reassemble the image that had been digitally disassembled back into an analog total picture. Such glass fibers, which were first developed around 1970, are composed of an inner core with a high refractive index and a covering with a low effective index. The total reflection between the two materials prevents the "escape" of light, which is conducted through the inner core up until the exit at the end of the fiber.

LEDs
LEDs (light emitting diodes) are special semiconductor diodes which convert current directly into light. LEDs emit only monochromatic light, and the color of the light is dependent upon the substrate and the phosphide emitting layer. LEDs are extremely robust, demonstrate a lifetime of 100,000 hours, and use up to 80 percent less energy compared to incandescent bulbs.

Softproofing
Images are displayed on the screen, using appropriate input and output ICC profiles, to simulate the color gamut of the used media -> "What You See Is What You Get". The system includes the EyeOne Display calibration tool form Gretag Macbeth for monitor calibration.

On-screen image correction
A dedicated correction keyboard is used to apply any kind of color, density, contrast and/or saturation correction to individual or multiple images. Corrections can also be made using the correction sliders on the monitor.

New Autonesting strategies
There are four (4) different options on how print sizes can be layout on the available roll width on panels, with the option of printing Fotoba Trim Marks.

Sort by Format
Images will be layout according to the print size. That means all images with the same print size will be grouped together

Sort by Queue Order
Images will be layout according to the queue order. That means all images regardless of their size will remain in order sequence.

Optimum Paper Usage
Images will be layout to minimize waste. Images get layout according to the best available space, regardless of the order sequence.

Optimum Cutting
Images will be layout to minimize waste, but at the same time arranged for easy cutting. That means that images get layout according to the best available space, regardless of the order sequence.

Thumbnail preview with soft proof
That allows to open multiple files and to preview them in thumbnail size for a fast inspection and image correction, that greatly reduces image correction times and increases productivity.

True Color Management Workflow
Suitable for TIFF and JPEG Files, allowing true ICC conversion of files through input profiles (default and/or embedded) and output profiles. The same profiles are used to simulate the image at the screen.

Proportional image cropping
In addition to the available cropping options, you can make now proportional cropping by positioning the cursor over the cropping mark corner and moving the cropping marks diagonally. This way, the horizontal and vertical cropping marks will be moved at the same time, maintaining the aspect ratio of the set print size.

New Autospooling software with sub-folders + name extension and also with the Durst ASCII-File for a fully automated workflow.
The software is using hot folder for automatic spooling and printing of jobs containing single files and multiple files. You can create as many hot folder as needed to suit various applications.

There are 3 auto-spooling modes:

Spooling individual files
Copy the files for printing into the requested hot folder. They are automatically copied to the print queue applying the preset hot folder parameters, where after the files are nested and printed.

Spooling files using folders
Copy the files for printing into a folder name the folder, than copy the entire folder into the requested hot folder. This way all files within the named folder are identified as one (1) order. They are automatically copied to the print queue applying the preset hot folder parameters, where after the files are nested as one print job and printed.

Calibration
The basis for the problem-free reproduction of high-quality images is precise calibration. For that, different test files are printed. These test images are read in through the densitometer and through a flatbed scanner, and the corresponding corrections for density and image quality are automatically corrected in the exposure system. In a few steps, even materials (paper and film) with wide variations are calibrated. With the use of the same material type or for quality controls in between, a quick recalibration suffices.

IndexPrint
Allows to create index prints on the workstation - but more important also directly via Autospooling, whereby print size, thumbnail size, background color etc. are freely definable.

Your advantages with the Software V3.7

• This is specially visible on smaller print sizes and in case an image contains fine details. This new image definition is comparable with a Lambda print produced at 200 ppi.
• Increased image quality with Softproofing and on-screen color & density correction
• Faster operation, as all necessary image corrections can now be done directly on the printer workstation.
• Nesting program that includes Fotoba trim marks, thus allowing the use of an economically priced cutting system.
• Improved and more flexible Autospooling workflow
• New service possibilities with index prints/contact sheets in any size
• Reduced calibration times

Spooling with ASCI files
ASCII files contain all needed job instructions for the individual files to be printed. To the hot folder, only ASCII files are sent. The corresponding images files are automatically picked up from t he server, corrections are applied, where after the files are nested as one print job and printed.
