Introduction: The International Printing Industry Standards And Norms, The Meaning - The Printing

Introduction of international standards and norms

, the meaning of the printing

In the printing industry, competition is everywhere, usually low profits, and customer satisfaction and retention rates and the quality of each service are closely related. In recent years, the printing industry's data standard development has made great progress. One of the most well known are those with market-driven standards, such as postscript and pdf. Now, as more and more being used in the printing industry, other important quality control standards and norms are also widely accepted by the international community.

Standards, methods, or the norm? The value of the standard known, however, how to implement standards, and printing standard specific vocabulary and abbreviations, it is not clear. The standards, norms and methods that people often confuse one of the mistakes.

Standard is the basis of comparison is to assess the reference point for other things. International Organization for Standardization (iso) to the "standard" further defined as: "by the people through consensus developed, approved by the authority, for repeated use in a wide range of documents, rules, guidelines or characteristics; it is applicable to a the corresponding results of these activities or aims to achieve a specific environment, the optimal order. "

Standard different from the norm: they are widely used, but also through a Management Institutions (such as iso) official evaluation and accreditation procedures. In some countries, iso standard which is equivalent to the law.

Other hand, the standard is for a job Design Detailed description of the standard. gracol and swop, that is the printing industry standard, the use of precise characteristics of the data set, on the specific printing process and printing materials regulated.

Method is defined as "a thing or carry out a certain way of things, technology or process." For example, g7, that is used to adjust the sampling and / or printing systems, to achieve the desired gray balance and tone curve.

Short, methods and norms is to make your way to achieve the expected standards. Many methods and norms can help you achieve iso

12647 goals, including the standard ide Union g7 (neutral print density and gray balance), swop (rotation Offset printing Print specifications),

Pso (from Germany fogra Standard Offset Printing Technology Association), and japancolor (from Japan Printing Machinery Association).

Iso, gracol, swop, g7, pso and japancolor

Iso12647 Iso12647 standards (printed in halftone color separation proofs and prints processing process control) is the number of countries worldwide comprehensive data on print quality based on the Commission evolved. It is a set of standards for a variety of printing processes (offset, gravure, flexo printing, etc.) for the technical attributes and visual features to provide the minimum set of parameters. The standard manufacturers and printing to provide guidelines for practitioners and help to set the device to the standard state. Measurement data from these printers can be used to create icc color profile and generate color matching and printing proofs. In short,

Iso12647 standards contribute to printing practitioners, pre-press department as well as printed information exchange between buyers.

Iso12647 is built, including ink, paper, measurement and visual observation of conditions over and above the standard. Including many parts of this standard. Iso12647 standard in every section, the different printing processes, the definition of the minimum value of the parameters:

Iso12647-1: halftone color separation proofs and production prints process control: parameters and measurement conditions.

Iso12647-2: offset lithography Iso12647-3: newsprint cold-type offset printing Iso12647-4: Publication gravure Iso12647-5: Screen printing Iso12647-6: Flexo Printing Iso12647-7: digital data directly from the proofs produced

Gracol name is generalrequirementsforapplicationsincommercialoffsetlithography commercial offset printing applications, meaning the overall requirements. gracol is for sheet-fed offset printing color reproduction standard. gracol7 under iso12647-2 international printing standards, a "neutral print density curves of gray," or to npdc as the core content of the standard specification of the printing conditions and implementation.

Fogra Association pso Offset production standard (processstandardoffset that pso) is located in Munich, Germany Image Technology Research Association fogra to bvdm (League of German print media industry) and developed for the German printing industry implementation. pso printing process is based on the standard iso12647-2 normative basis. The same as gracol, pso strictly follow the iso12647-2 specification, also added some additional specifications, especially for Digital proofing Or in conflict with the color field situation, using the middle tone color priority.

Fogra promoting "media standard printed 2010 -" It is a data, film, proofing and printing technology product standards. The criteria for pso summary version of the specification, including the recently updated criteria for the iso. For now, only through the following link to visit the German version of this document; English version is expected to be available before the end of March 2010.

Fact, pso and gracol the difference between the two methods is very small. They both advocate the middle tone control is more important than the field color control

Swop standards for web offset printing. swop a web offset printing color reproduction standard. swop standard iso provisions apply to the use of ink and paper for web offset printing. There are two swop Norm: swop3 used in the printing paper 3, but swop5 used in the printing paper 5.

G7 this from proofing to printing control method for printing and / or proofing color calibration provides a relatively new approach. From print buyers to design agencies, to printing, and finally back to print buyers, g7 fully established, a closed-loop vision-based control methods. Using this method, we can actually any kind of printing press or the substrate, while retaining the same visual effect common. g7 not only apply to commercial print, newsprint also apply to publications and printing, and flexographic printing, screen and Ink jet Print.

G7 based on image data, spectrophotometry, and computer to plate technology foundation. It is based on a theory - that is a visual effects show how the image in the eyes of the state
