Enfocus has released an upgrade to the Connect product family with support for Switch 2017 and Pitstop 2017. Connect helps creative and print professionals create print ready PDF files and delivers them, with job ticket specifications, in an easy to use way from most applications to internal or remote locations.
The latest versions of the Axaio plug-ins for InDesign MadeToPrint and MadeForLayers allow the definition and the PDF export of layers with Processing Steps metadata:
PDF Processing Steps were defined by the Ghent Workgroup and will soon be releases as ISO-Standard 15993. PDF Processing Steps allow standardized identification of non-printing objects in packaging files (e.g. dieline, braille, varnish, folding) and help automating production.
After the version jump from 2015 to 2015 in April, Acrobat now was updated to version 2018 after only half a year. But only for the subscription variant (Continuous track). The subscription variant (Classic track) stays with version 2017:
- Acrobat 18.009.20044 for subscribers of the Document Cloud (Continuous track)
- Acrobat 17.011.30038 for users with a perpetual license (Classic track)
(The update can also be installed using the Acrobat menu Help > Check for Updates….)
Many users have got an automatic update since the corresponding option in the preferences was recently activated by default.
Despite the divergent version numbers all of the new features of this update are available in both variants!
The new Acrobat versions support PDF 2.0. Documents using PDF 2.0 are now opened without a warning. They can also be saved as PDF 2.0. However PDF 2.0 is not supported in Acrobat Preflight (yet). Since Callas has already integrated PDF 2.0 checks and fixups in pdfToolbox 9.4 this feature will certainly soon be available in an upcoming Acrobat update.
Unfortunately Adobe is quiet about which of the new features of PDF 2.0 are supported in the new Acrobat versions!!!
The new version 2.0 of the text based PDF comparison tool PDiff from CSci brings new features and more comfort for the user.
PDiff 2.0 features an additional format for PDF reports with a side by side view of the two documents with highlighted changes. The report also contains PDF comments:
The InDesign update to version 13.0 (2018) released in October 2017 features some enhancements in the export of accessible PDFs:
- Alternate text for graphics and InDesign objects
- Group level tagging
- Support for footnote
- Anchored text frames and anchored groups tagging
- Master pages tagging
- Index tagging
- List tag language
- List tagging
- Caption tagging
- TOC tagging structure
In the upcoming weeks the Ghent (PDF) Workgroup (GWG) is organizing a series of free webinas. These webinars are hold by well known PDF experts from Europe and the US. Recordings of past webinars are also available.
I will conduct a webinar about the Ghent PDF Output Suite on January 11th, 2018.
This comparison feature will certainly help me in the development of upcoming versions the thirty PDFX-ready preflight profiles.
Martin Bailey, CTO of Global Graphics (Harlequin-RIPs), talks in his blog about tests to avoid the orange peel effekt for inkjet presses using special screening methodes.
When inkjet presses print on non-absorbent, poorly wettable media such as flexible plastics or metal, prints are characterized by a mottle effect that looks a bit like orange peel. This effect seems to be triggered by ink shrinkage during cure. This can be corrected with a halftone with specially designed characteristics.
In order to avoid these artifacts Global Graphics will soon introduce a new screen technology.
It’s interesting that the topic of screening becomes important again for the new printing technologies…
In the morning of Octobre 26th, 2016 we have launched the PDFX-ready Online Tools. which I had developed for PDFX-ready. Right at the beginning we offered three tools:
- PDF Preflight (with the well known PDFX-ready preflight profiles)
- Color Preflight (Analysis of the undefined color spaces in a PDF)
- ISO<–>PSO Converter (for color transformation between the old and new offset standards)
The experience we made in the past year is pretty good. The Enfocus Switch server with the applications Callas pdfToolbox and ColorLogic ProfileTagger is running very stable. But of course there were a few problems.
The question of the last survey was how many of your PDF files are checked by a Prelight tool.
The result of the last survey on how many PDF files are checked by a preflight tool is surprisingly very positiv. The majority of the PDF files of the readers of PDF-AKTUELL run through a preflight check. But there are still almost 20% of the users were less than a quarter of the PDFs are checked:
In my new seminar PDF Color Management I discuss four different color conversion technologies:
- Pure ICC color conversion (ICC)
- ICC color conversion with exceptions (ICC-Plus)
- DeviceLink conversion (DVL)
- Smart color conversion (Smart)
Which PDF tools do support these technologies can be seen in the following table:
In preparation of my new seminar PDF Color Management I have tested the image compression before and after color conversion in the most popular PDF tools.
In highend PDFs destinated for quality printing the images are usually compressed using JPEG maximum quality. Before color conversion the images must be decompressed and afterwards compressed again. Acrobat always uses JPEG medium quality for this recompression. The consequence is that there is an (unexpected) loss of quality of the color converted images (see table).
On October 15, 2017 Adobe discontinued the support of Adobe Acrobat XI und Adobe Reader XI. Adobe only supports during five years. That means that Adobe no longer provides technical support, including product and/or security updates, for this version of the application.
However the software can still be used!
According to my survey last year Acrobat XI is the most used Acrobat version by my readers. This is also confirmed by the feedback of the attendees of my seminars.
The ISO has released the new standard ISO 16613-1 PDF/VCR-1 (PDF for variable content replacement). VCR allows to define PDF templates for variable data. The templates are defined as PDF/X-4 with place holders for the variable data which are merged during print production in real time. Contrary to PDF/VT when using PDF/VCR the variable data must not be saved.
Use cases for this new standard are security sensitive printing applications like printing credit card pins, serial numbers (e.g. for pharmaceutical packaging) or tickets. In a news release of NPES the format is described in more details.
