ELAN Proofer family

ELAN Proofer family -- the book production software for the digital, pre-press and printing workflow.
Imaging Module

The ELAN Imaging Module scans hardcopy documents and/or imports raster images or raster PDF files. Advanced image processing, raster editing and document assembly can be applied to the digital images. The assembled document is then passed through to the ELAN Proofing Module for alignment and proofing and/or directly to the Imposition Module.


Input formats:

The imaging module is capable of handling the following input formats:
imagin3.jpg Raster Images: More then 80 different raster file formats, including B&W, grayscale and color images. Examples: TIFF, PNG, JPG, BMP. Multipage TIFF files can be split into separate files for processing.
imagin4.jpg Raster PDF: PDF files which contain full page raster images. Originating applications include XEROX DigiPath, Adobe Acrobat (scanned images), output from many bundled scanning applications, etc.
The images are extracted from the PDF file in their native format without any degradation in the quality introduced by a rasterisation (RIP) process.
imagin5.jpg Scanner: Any TWAIN compatible scanner capable producing acceptable image quality that supports B&W, grayscale and color modes, including the Xerox FreeFlow Scanner 665 via a Adaptec SCSI card.

Job Handling:

The imaging module uses a job concept with the aid of the ELAN Job Tree user interface. The ELAN Job Tree is based on a relational database where all relevant information is stored. This mechanism provides 2-way communications with the Proofing module.
  Insert page(s): By way of context menu or drag and drop
  Delete Page(s)
  Re-arrange pages
  Insert blank pages
  Hierarchy, list item and outlining through ELAN Job Tree

Editing and Image Processing:

imagin6.jpg The following raster editing tools are available:
Select – move, snap,
resize selection
Quick erase
Delete inside
Delete outside
Border removal
Line removal
Detect selected area
Detect page
imagin7.jpg Batch processing based on selection of some or all files:


Border removal
Page positioning

imagin8.jpg Advanced Image Processing: Addresses the scanning and printing of mixed-content (halftone images + text) pages by grayscale processing and multiple-layer page decomposition. Features automatic or manual halftone page region selection and batch processing based on individual or common settings.
B&W input: Convert selected halftone areas to grayscale and apply image optimization and moiré-pattern removal.
Output: Multi-layer PDF image file consisting of B&W background image for crisp text/line-art and 8-bit grayscale overlays of optimized halftone images
Grayscale or Color Input: Select halftone picture areas for image processing and optimization. Convert the text areas of the page to B&W format using dynamic thresholding.
 Output: Multi-layer PDF image file consisting of B&W background image for crisp text/line-art and 8-bit grayscale or color overlays of optimized halftone images


Raster jobs created by the Imaging Module will be converted to PDF format. The generated PDF file can be transferred to the Proofer and/or the Impositioning and/or  the Printing and Release module.
Proofing Module

The Elan Proofing Module accepts PDF, raster PDF or Postscript file(s) as input.  The input file may be normalized prior to proofing and alignment. Pages can be visually checked for front-to-back registration and aligned as necessary.  The aligned document may be passed through to the Elan Imposition module or released for printing and/or archiving

Input formats:

The Proofer Module is able to accept input files originating from the Imaging Module or any PDF, Postscript or Encapsulated PostScript file. The input from the Imaging Module will be in raster PDF file, and the preview images will be directly transferred.
proofe10.jpg PDF: Full vector or raster-based PDF files.
proofe11.jpgproofe12.jpg EPS and PS files: These files will be converted to PDF format.


proofe13.jpg The input files will be normalized prior to job creation based on user preference settings. The normalization process will create compliant PDF files suitable for rasterisation and further processing. It will eliminate most problems associated with PDF files that are encountered in a multi-customer printing environment.
proofe14.jpg The normalization process integrates Adobe Acrobat and Adobe Distiller in a batch process transparent to the operator. Optionally, it can be invoked as a tool for fixing font, embedding or structure related problems with Adobe PDF technology.

Page Alignment:


Once a Proofer job is created, all the pages will be represented as bitonal raster images which will then be analyzed for content. Statistical analysis will be used to determine tendencies in the page layout and adjust for irregular pages (for example: chapter pages, front matter). Page templates can be saved and loaded. After all pages are aligned and proofed, a PDF file will be created, which is equivalent to the input file, except that page canvas and/or coordinates are changed.


Resize Canvas: New, uniform canvas can be applied to a PDF file or a set of files.


Align Content: Margins can be established for precise page alignment. The alignment is template based and will automatically adjust for irregular pages in a recto-verso environment.


Proofing: all pages can be displayed in front-to-back mode and aligned manually or apply alignment to selected or all pages.

Page Editing

Raster files in a job created by the Imaging Module input can be edited/updated by the raster editing tools used in the Imaging Module. The editing and updating is transparent to the user.

Output/Next Step:

The output of the Proofer Module is a PDF file that represents the perfectly aligned, single-page layout book block. This file can be submitted to the next workflow step, the Imposition Module, or can be directly printed or archived.

Impositioning Module

The Elan Impositioning Module is an integration of an Adobe Acrobat impositioning solution and the Proofer module. Acrobat plugins are used to transfer data, create a new, imposed PDF and provide a seamless user experience.

Input formats:

The Impositioning Module is capable of accepting PDF files as input.

proofe10.jpg PDF: Full vector or raster-based PDF files.


proofe19.jpg The Impose workflow icon will be available as soon as a Proofer job is created. A file can be directly imposed or imposed only after page alignment. The file will be passed to Adobe Acrobat 6.0 for impositioning.
Impositioning Menu A custom Acrobat menu will be available to perform the actual impositioning. A wide array of choices are available, and settings are automatically saved and can be recalled at will. Once the file is properly imposed in Acrobat, it will be transferred to the ELAN Proofer environment
Proofing After Impositioning The imposed file can be rasterized again for final proofing. This step can be skipped, if needed.


The created files (Output file and Imposed file) can be now transferred to the Printing and Release Module.

Printing and Archiving Module

The Elan Printing and Archiving module handles the make-ready output or imposed file received from the Imaging, Proofing or Imposition Modules. The file(s) can be submitted to a cut sheet or continuous feed printer using LPR or Xerox XDS print submission. Several choices are available to archive the job or just the output files.

Print Submission:

print_1.jpg Professional Proofer™ provides submission capabilities.

LPR print submission: Different queues may be defined to submit directly to a specific queue.

XDS submission: Integration with the standard XEROX FreeFlow Print Manager job ticketing utility for finer control. 


print_2.jpg Besides the primary output files, an archiving module is also included, where the operator has complete control of the archive location of the original input files, working and output files, including the options to archive the whole job or burn them to a CD/DVD ROM

Integrate with other applications:

print_3.jpg The archiving settings lend themselves to further, file-system-based application integration on the back-end.
