    Stephan Jaeggi09-03-2015

For one webinar fee more than attendee from a company can attend the webinar (e.g. in a meeting room with a computer projector and speakers).

  • What are the disadvantages of webinars compared to regular seminars?

    Stephan Jaeggi09-03-2015

    One disadvantage is that there is no direct contact between the presenter and the attendees.

The attendee also has to restist to try out the topics of the webinar immediatly since he risk to miss part of the webinar content.

    Stephan Jaeggi09-03-2015

    There are similiar topics around the use of PDF for print production than in the seminars. However due to the shorter time frame of a webinar only one topics is covered in one webinar. This is an advantage for the attendees since they can especially pick the topics they are interested most.

    Stephan Jaeggi09-03-2015

    Most of the webinars are hold multiple times. The attendee can try to participate again on an other day or he will get a full refund of the fee.

  • PDF/X Standard
  • What is PDF/X?

    Stephan Jaeggi12-08-2014

    PDF/X is the popular name for the ISO standard 15930. The "X" stands for "blind eXchange".

  • What is PDF/X?

    Stephan Jaeggi09-03-2015

    PDF/X is the popular name for the ISO standard 15930 which covers the exchange of digital prepress data. PDF/X defines additional requirements (e.g. all fonts must be embedded) and restrictions (e.g. no RGB images without ICC profile) as well as some additional information (e.g. output intent, page geometry) which allow an unambigous output of the PDF in any print shop.

  • Since when does PDF/X exist?

    Stephan Jaeggi09-03-2015

    PDF/X-1a was introduced in 2001. PDF/X-3 was added in 2002 and PDF/X-4 was published in 2008.

  • Why is there more than one PDF/X variant

    Stephan Jaeggi09-03-2015

    In PDF/X-1a you can only use CMYK and spot colors. PDF/X-3 also allows ICC based color (e.g. a RGB image with a ICC profile). In PDF/X-4 modern PDF features (like live transparency and layers) are supported. In addition there is PDF/X-5 for special use cases (e.g. incomplete data with external references or PDFs using more than four process colors).

  • What is the meaning of the year after the PDF/X name (e.g. PDF/X-4:2010)?

    Stephan Jaeggi09-03-2015

    This number represents the publication year for the particular standard. Sometimes older versions (like PDF/X-1a:2001 and PDF/X-3:2002) are still valid beside newer versions (PDF/X-1a:2003 and PDF/X-3:2003). In the case of PDF/X-4 the first version PDF/X-4:2008 was replaced by PDF/X-4:2010. The new PDF/X-4 version features a more flexible definition of layers (optional content) which is important for packaging.

  • Which PDF/X variant should be used?

    Stephan Jaeggi09-03-2015

    If no transparency is used in the layout then PDF/X-1a is usually sufficient. Since in PDF/X-1a and PDF/X-3 transparency is not supported, transparency must be flattended during PDF export. This can lead to a (sometimes massive) loss of quality. If transparency is used in the layout of a document the use of PDF/X-4 is highly recommended!

  • PDF/A Standard
  • What is PDF/A?

    Stephan Jaeggi09-03-2015

    PDF/A is the popular name for the ISO 19005, the standard  for digital archives based on PDF.

  • Is there a relation to PDF/X?

    Stephan Jaeggi09-03-2015

    PDF/X and PDF/A are based on the sample principles. For PDF/A:2005 a lot of requirements of PDF/X-3 were included (e.g. output intent). For the PDF/X-4 specification some requirements of PDF/A-2 have been integrated (e.g. XMP metadata, stricter rules for font embedding). The goal was to make PDF/X-4 and PDF/A as compatible as possible in order to make it possible that a PDF document can be compliant to both standards. This is important since a lot of print buyers want to included their prepress data in their digital archive.

  • Where can I found additional information on PDF/A?
