The Ghent Workgroup (GWG) released an innovative specification to address the Sign & Display segment (aka Large Format Printing (LFP). Given the diversity within this segment, the new specification incorporates the notion of viewing distance and scaling factor. This allows having one specification, but still to address the big differences in printing techniques within typical sign & display jobs.

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 his first article Martin Bailey, CTO of Global Graphics, discussed the basics for calculating the required data rate of a RIP, the second article deals with the selection of the class of the Raster Image Processor (RIP):
The articles are primarily aimed at manufacturers of output systems (digital printing, CTP). However, it is also interesting for users who wish to learn more about the architecture of RIPs.
In addition to the article What does a RIP do? Global Graphics has published an article on calculating the size of the required data rate of a RIP. This is the first part of a two part series on Choosing the class of your Raster Image Processor (RIP).
The article links to an Excel spreadsheet with several calculation formulas for sheetfed and web printing. The formula for sheet-fed printing can also be used to calculate the amount of data for a platesetter.
In the Ghent Workgroup (GWG) we have recently developed a new specification for applications and preflight profiles for Display & Sign.
On the new landing page Display & Sign one can find the new specification and also beta versions of the preflight profiles for the Callas pdfToolbox and Enfocus PitStop Pro, which will be publicly tested in the next weeks. A whitepaper will follow later.
