    callas pdfChip vs classic command 'Print' in a browser?

    "callas pdfChip lets you take an HTML file and turn it into a high quality PDF file.
    The difference to do the classic commands 'Print' in a browser and 'Save as PDF file',
    is that callas pdfChip provides an extreme degree of control of what is happening,
    especially from a prepress view, when creating high-quality PDFs from HTML.
    You can use spot colors, you can address transparency, and you can set
    picture geometrical boxes, ... so it is not quite the same!"

callas pdfChip
a modern PDF generator creating high-quality PDF from HTML templates

    callas pdfChip is a command-line conversion tool that takes an HTML file
    – optionally augmented using CSS3 and JavaScript – and performs a high-quality
    conversion to PDF that is ready for print or archival (PDF/X or PDF/A).

    pdfChip is ideally suited for high-volume dynamic HTML to PDF generation
    of single and multi-page PDF documents of anything that is normally shown on
    a web site itself, but at times needs to be available in a printable form as well.

callas pdfChip Workflow - Picture

    With an increasing amount of content stored in web-based
    content management systems (CMS), callas pdfChip will prove
    to be particularly valuable to businesses needing to provide up-to-date
    information to customers through their own preferred channels.

    callas pdfChip is recommended when businesses need flexible and
    automated high-volume PDF creation.

    Example cases include content-rich transactional printing,
    book and catalog creation, and web-to-print applications or imposition.

    callas pdfChip allows businesses to dynamically format content
    for distribution through any channel they require.

    callas pdfChip is based on easy-to-use,
    common and established web technology

    callas pdfChip is built on standard technologies such as
    Qt WebKit, HTML, CSS and JavaScript that are widely known
    and that require no dedicated development resources.

    The HTML templates used by callas pdfChip are very similar to
    what would be needed for use on websites.
    A good understanding of up-to-date web technology is
    sufficient to get started with pdfChip.
    Anyone with experience building up-to-date website solutions
    will have enough background in HTML, CSS and JavaScript
    to get going with the product very quickly.

    There is no need to learn custom XML or XSL-FO based languages;
    anything that works in HTML is immediately usable in callas pdfChip.
    That sets callas pdfChip apart from solutions that have their
    own custom XML or XSL-FO based template languages.

    The fact that callas pdfChip is a command-line tool as opposed to
    a development library means that its functionality can easily be
    integrated into all kinds of different custom environments without
    needing dedicated development resources.

    callas pdfChip can also be driven by automated solutions
    such as Laidback Solutions FileTrain or Enfocus Switch.

    Wide applicability across different markets

    With its extensive feature set and high-quality PDF output,
    callas pdfChip is ideally suited as the back-end high-volume PDF
    creation solution for many different applications, amongst others:

    • Imposition and content aggregation workflows

    • Creating downloadable web content

    • Composition workflows where templates and user contents
      have to be combined on the fly and where printable
      PDF documents have to be delivered

    • On-the-fly preparation and publishing of magazine and newspaper content

    • On-the-fly preparation and publishing of sales literature and user manuals

    • On-demand book printing

    • Dynamic generation of one-off content such as
      real estate property information, tickets, stubs, order data, invoices, receipts,…
      (for example in web-to-print environments)

    • Variable data printing where templates have to be filled with data
      coming from a data source (such as a database or CRM system)

    • Transactional printing workflows where transactional data
      needs to be combined with visually rich designs

    Use Case - Create an HTML template for ZUGFeRD-based invoices

    This article explains a rather complex project that shows how a
    HTML template for invoicing can be created in Adobe InDesign,
    exported into a callas pdfChip template using the export filter and
    then turned into ZUGFeRD-invoices.

callas pdfChip - Adobe InDesign HTML Invoice Template - Picture

    As always when it is about creating various instances from a template
    there is need for a data source that has the variable data.

    This example uses XML files in the ZUGFeRD format.
    (ZUGFeRD is a German standard for electronic invoices and
    a ZUGFeRD invoice consists of a PDF/A-3 container
    into which an XML invoice is embedded)

    This example reads data from such ZUGFeRD invoices,
    puts it into the corresponding objects in the template and
    creates a single PDF file for each invoice.

    Finally the XML is embedded into the PDF and
    the file is saved according to the PDF/A-3 standard.
    So a full ZUGFeRD invoice is created.

      • On all platforms, referenced image and PDF data
        is now handled in an optimized way to avoid
        high-memory consumption during PDF creation.

      • The latest version of the TEC-IT barcode library has been
        integrated for more complete barcode support.

    News in callas pdfChip v1.4

    • Page scaling factor (UserUnits)

      UserUnits can be defined in HTML/CSS.

    • Optional content + Processing steps
    • Support for defining Layers (optional content) for content objects
      incl. Layer groups and information for Processing steps in CSS.

    • New option: --zoom-factor
    • The precision of placements can now be increased using
      the --zoom-factor parameter for applications that need
      very high calculation accuracy when positioning objects.

    News in callas pdfChip v1.2

    callas pdfChip v1.2 update focuses on ease-of-use:

    • Debug Plug-In for Chrome
    • One of the challenges in developing pdfChip templates,
      is figuring out the right HTML to get the effect in PDF that you want.
      This is especially difficult, because an HTML template using JavaScript
      will not open correctly in a standard browser such as Chrome.

      With pdfChip 1.2 comes a Chrome plug-in that emulates
      the pdfChip specific JavaScript objects and functions.
      This makes it possible to use the Chrome JavaScript debugger
      for your templates.

    • Extended support for barcodes
    • pdfChip contains a built-in barcode library that supports
      over 100 (119 to be precise) barcode types.
      Many of these barcodes have special features and
      parameters that could not be used in pdfChip.

      From pdfChip 1.2 on, these specific parameters can also be used in
      your templates, making the barcode functionality even more powerful.
      At the same time, it is now possible to use much more coloring schemes
      for barcodes, opening up a wide array of more creative barcode uses.

    • InDesign template generator
    • pdfChip templates can be created with any good text editor
      or with a tool specifically targeted towards web design.
      For those people who feel more comfortable with design tools,
      such as Adobe InDesign, callas released the pdfChip template
      generation export filter for Adobe InDesign with the pdfChip 1.2 release.

      This export filter converts an InDesign document into a correct
      pdfChip template, correctly taking over the positions of all elements
      on the page, the color and styles of page elements and more.
      This allows to dramatically reduce the time required to build a
      correct pdfChip template.

    • Additional features
    • Creating a template that correctly loads fonts and images
      can be difficult, because of the asynchronous way pdfChip
      (and the WebKit engine within) handle those page resources.

      In pdfChip 1.2, there is a new, elegant way, to handle this problem.
      pdfChip is capable of outputting more than one PDF document.
      When generating business cards for example,
      each business card could be saved in a single PDF file.

      It is now also possible to cross link between those files.
      This means that each generated PDF file can contain links
      to one or more of the other generated PDF files.

      Most of the time, pdfChip templates will be a mix of
      HTML, CSS and JavaScript, and where necessary enhanced
      with things, such as MathML or SVG.
      Sometimes, more simple needs could be handled by a
      single SVG file however. pdfChip 1.2 allows specifying a single
      SVG file which will be converted into a PDF seamlessly.

    News in callas pdfChip v1.1

    callas pdfChip v1.1 update adds a number of features
    especially useful when creating long, dynamic documents:

    • Making integration easier
    • Using pdfChip to convert an HTML template to a good
      PDF file is straightforward and easy.
      pdfChip v1.1 focuses on making integration of the tool in a
      larger project just as easy by adding a number of features:

      • Control the maximum number of pages in the generated PDF file.
      • Makes it e.g. possible to create single page PDF files in just
        one go instead of one PDF file with many pages.
        Since the destination PDF can now be defined in the JavaScript
        code it is possible to start a new PDF whenever needed.

      • Enhanced error reporting,
        specifically for JavaScript and when placing bar codes.
      • During development it can be critical to understand what
        errors occur and how to adjust the HTML template.
        Error reporting is now improved in order to make it easier
        to develop complex PDF publishing applications.

      • Passing command-line variables straight to the HTML template.
      • Allows for passing command-line variables straight to
        the HTML template, where JavaScript can pick it up and use it
        to shape the resulting PDF file.

        The ability to pass this kind of small information to an HTML template
        adds even more flexibility to PDF publishing; compared to what was
        already possible with the highly dynamic HTML/JavaScript architecture.

    • Long, dynamic PDF documents
    • Long documents, that need to include lists of references such as
      a list of figures, list of tables or simply a table of contents,
      were a challenge in pdfChip v1.0.

      In pdfChip v1.1 the new concept of a “list collector” is implemented:

      • List collector.
      • This new feature allows content to be marked using
        simple CSS and stores information about this content in a
        JSON (JavaScript data) file.
        This information can then be used to automatically
        create a table of content with page numbers for
        the generated PDF document for example.

    • Advanced templates
      • Device-N color space.
      • Device-N color space is an advanced PDF color space
        that is essential for content where a number of different
        spot colors or a combination of CMYK and spot colors is
        used for page objects like images or vector graphics.

      • Improved placing of PDF files.
      • Placing of PDF files has been improved.
        pdfChip provides information about PDF files that are placed
        in the HTML template, e.g. about their trimbox or bleedbox.
        This information can then be used in JavaScript
        to modify the placement.
