Enfocus Connect 2017 available

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.

I have used Enfocus Connect to create the Connectors for the PDFX-ready Online Tools.


MadeToPrint & MadeForLayers
support Processing Steps

The latest versions of the Axaio plug-ins for InDesign and Illustrator 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.


Ghent Workgroup Webinars

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.


Callas pdfToolbox 9.4 with PDF 2.0

Callas has released version 9.4 of pdfToolbox. The update supports the new ISO standard 32000-2 (PDF 2.0). In addition there is a new feature for comparing two profiles:

This comparison feature will certainly help me in the  development of upcoming versions the thirty PDFX-ready preflight profiles.

Screening technology to avoid the orange peel

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…


One year PDFX-ready Online Tools

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:

There is a FREEWARE and PREMIUM versions for members of PDFX-ready.

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.

New survey: Which Preflight tool(s)
are you using frequently?

The question of the last survey was how many of your PDF files are checked by a Prelight tool.

In the new survey I would like to know which Preflight tool(s) are you using frequently

Which Preflight tool(s) are you using frequently?


Most PDF files are checked by Preflight!

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:

Four color conversion technologies
for PDF

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:

Quality loss after color conversion
in Acrobat

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).

ZePrA 6 from ColorLogic with PantoneLIVE integration

Version 6 of the ColorLogic color server features an integration with PantoneLIVE. This allows to online access spectral definitions of spot colors.

There are additional improvements in the area of spot color iteration and better administration of spot color libraries. In addition there are improvement in handling queues and configuration.

In the online help for the ZePrA the new features are covered indepth.


eciCMYK (FOGRA53) as new CMYK exchange color space

ECI has released the ICC color profile eciCMYK.icc. It’s based on the printing condition FOGRA53 defined by Fogra. The goal is a large gamut exchange space which covers all printing technologies (offset, gravure, digital). The eciCMYK profile can be download for free.

Since the gamut of eciCMYK is larger than any real printing gamut and the profile allows a high total ink coverage (TAC), this profile is not suitable for printing.

Callas pdfToolbox 9.3 with new
color separation feature

The update 9.3 of pdf Toolbox from Callas adds a new feature for the color separation of CMYK and spot color pages. This sounds like a déjà vue. In the late 1990ies color separation of PDF pages was a huge topic. (I was working on a software solution myself.) But it seams that there is still a need. Just recently I had such an enquiry. The customer would like to check separations on the monitor and print them on a laser printer if necessary.

During the first test I recognized a mess with the separation names in the page label fields when the PDF had multiple pages. I have reported the bug to Callas and after a two weeks the problem was fixed in an update. Therefore you should update to version 9.3.434.


Impact of PDF 2.0 on Print Production

Martin Bailey, CTO of Global Graphics and member of serveral ISO committees regarding PDF standards, talks about the impact of PDF 2.0 in a whitepaper (19 pages) and a webinar (YouTube, 40′). He also covers the risks and gives some recommendations for the transition to PDF 2.0.


Nine reasons to preflight

The Ghent Workgroup (GWG) has published an interesting poster:

On the front page the GWG is presented. On the back nine reasons to preflight are listed (compiled by belgian VIGC). Each topic is illustrated with an eample.

This page can be used to check how certain PDF definitions are displayed in different viewers (Acrobat/Reader, Apple Preview, etc.) and output devices (printer, proofer, imagesetter).

In addition one should check this PDF with a preflight tool in order to also detect the problems which are not visible. For this the preflight profiles GWG2012 or GWG2015 (part of Acrobat DC Pro, Callas pdfToolbox, Enfocus PitStop Pro) and of course the preflight profiles for Acrobat Pro from PDFX-ready are highly recommended.
