Global Graphics has published two basic articles on modern raster technologies in its blog:
- The first article What is halftone screening? explains the reason for screening and the differences between AM and FM screening.
- The second article Where is screening performaed in the workflow? explains which factors determine whether screening is performed during rendering or afterwards.
Global Graphics has updated their popular «Do PDF/VT Right™» guide.
The english publication offers a good overview on PDF/VT and tells what is necessary for an efficent use of this standard.
In addition to a general overhaul there is a section on the new ISO 21812 standard that allows workflow controls to be added to PDF files.
The new edition also contains notes on Harlequin-specific hints, to get even more speed out of your DFE if you are a Harlequin user.
In September 1999, when the first pure PDF workflow system «Prinergy» was introduced by Heidelberger Druckmaschinen and Creo (now Kodak), four tutorials on PDF Workflow were published, which I had written for the two manufacturers.
The tutorials were distributed in printed form (I still have some copies in my basement) and as digital eBooks (of course interactive PDFs) in German and English for free download. The interest was very big. I stopped updating the statistics after more than one million downloads (from several platforms).
The PDF Association has published a new guideline for the technically correct creation of accessible documents. The manual, entitled Tagged PDF Best Practice Guide: Syntax, is intended primarily for developers. It is intended to help developers understand the syntactic properties tagged PDFs need to meet accessibility requirements.
The guide is intended for interested parties who want to prepare accessible PDF documents in detail. On 70 pages, aspects such as PDF/UA as the standard for accessible PDF documents and general regulations are explained. In addition, developers and experienced users are provided with examples of the standard structure types and important information about attributes as well as properties, text features and other properties of PDF.
