As you know, PDF is a universal file interchange mechanism. It makes it possible to share files across operating systems and devices, so it has become the format of choice in the graphic arts for file sharing. ISO was developed to make PDF processing a bit more consistent and reliable for different types of print workflows.
ISO standards sound dull but they really can be useful for your work. Software developers working in the graphics industry have implemented many of them already, making it much simpler for end users to create print-ready files.
What matters more is that software developers and service providers understand how to implement them in their particular situation. This brings us back to ISO for quality management systems. Ideally print service providers should be applying the ISO principles to their production processes as well. If they are doing this you can be certain that whatever form your wild format project takes, it will be well produced. Just choose your country in the list below and we'll find your local association.

Revision 2 now available, revised PrintWide is a new, extremely large-gamut CMYK dataset designed to encompass the gamut of virtually all inks or colorants in all known color printing systems and serves as a CMYK translation space and G7 aligned saturation booster. This download contains a spreadsheet that allows for manual verification of Idealliance print conditions. The procedure utilizes the tristimulus correction methodology defined in ISO Annex A for correcting measurements based on two backing materials.
Often working with print service providers, they have developed an amazing array of new applications. Many of these, such as variable data printing, are only possible with direct digital output devices. But for long or short runs on conventional or digital presses, colour output quality must still be managed. And for jobs produced using several different printing systems, process and colour data control are absolutely vital. Print buyers who use multiple printers to produce the same job, or versions of it, need to be able to trust that all prints have a common colour appearance.
But markets are dynamic and clever, and they respond to opportunities. When it comes to proving that digital printing system output is comparable to that of offset, savvy digital print companies have turned to ISO Graphic technology — Process control for the production of half-tone colour separations, proof and production prints — Part 2: Offset lithographic processes.
This information is the characterisation data that describes a given printing process, so the stringent requirements of ISO summarise expectations for accurate, high quality colour production. Many digital printing devices may produce printed pages at a different rate than their nominal speed due to various factors. These include but are not limited to host computer, driver, application, operating system, and type of connection to the printer USB, Ethernet, wireless.
In addition, job characteristics such as black-and-white vs. Tests are conducted with the device set to plain paper with the quality level at the factory default. For color devices, black-and-white tests are run by setting the device to print in black-only mode. Testing is done with single-sided printing, as well as with two-sided printing if automatic two-sided printing is standard on the device. Three different methods of timing are used. Time from the initiation of the print job on the host computer until the last page 4th page of the first set lands in the output tray The time resulting from this measurement is referred to as First Set Out Time FSOT.
