Parameters and measurement methods The latest revision was done in ISO specifies parameters that define printing conditions for the various processes used in the graphic arts industry. ISO defines vocabulary and establishes a minimum set of process parameters that uniquely determine a printed four-color half-tone image which are also referenced from other parts of ISO The parameters were selected based on the following process stages "colour separation", "making of the printing form", "proofing", "production printing" and "surface finishing".

Search for: ISO Within the International Organization for Standardization a separate workgroup occupies itself with defining standards for the printing industry. One of these standards is called ISO It provides printers with a set of quality control guidelines for their printing process.
ISO for instance covers the offset printing process. Standardizing production means that a number of production parameters need to be clearly defined, along with a specific tolerance on each. In the case of ISO these definitions include: the color and transparency of printing inks definitions of paper types solid tones, which are described with CIELAB values tone value increases TVI , per paper type and color Essentially these guidelines, combined with proper calibration and rigorous quality control tests guarantee a consistent and predictable quality in the re production of printed matter.
As a printer you can implement ISO by following a training, during which you will be taught about the standard and receive the proper documentation. The training will also include a hands-on part, in which test sheets will be printed to assure your printing procedures meet the quality control requirements.
The teacher will discuss corrective measures to stay within the ISO tolerances. Their names also include the year when the standard was established or last modified. Because the standard covers various printing methods, a printer only needs to implement a part of the full specifications. ISO describes the parameters and measurements methods. Essentially provides the basis for the subsequent print related settings.
ISO defines the process control settings for offset lithography. ISO defines the process control settings for newspaper printing, more specifically coldset offset lithography on newsprint ISO defines the process control settings for publication gravure printing, which is used for high volume magazines, catalogues, etc.
ISO defines the process control settings for screen printing. ISO defines the process control settings for flexographic printing. ISO is still being work on. It will cover off-press proofing processes. Benefits of working with a standard like ISO Adhering to the ISO specs can offer the following advantages to a printer: Savings on paper and ink as well as make-ready time Improved process stability Better quality and consistency Meeting the expectation level of print-buyers.
There are large corporations and governments that insist that their printed matter is produced by a company that is ISO certified. Better matching between proofs and prints As a printer you can get a training on implementing ISO Various industry organisations, consultants and vendors offer this type of service.
The printer can then decide: to use some or all of the guidelines of the ISO standard as an internal guideline or ignore them all, of course. This requires certification by an outside party. The ISO organisation itself does not certify printers but the company doing the training may be accredited to offer this service. A new audit is needed all 3 years to renew the certification. Additional sources of information The ISO web site is about as dull as a site can get.
They also expect you to pay for the official documentation. Please use the comment function if you are aware of any other good documentation about ISO
