This article is compiled from the EPS (Electronic Prepress) briefing. EPS briefings are often involved in the latest standard areas. Let's take a step back and look at the history of standards and standardization organizations and the differences between them and the parameter description organizations. A large number of standard and parameter descriptions are used in the printing and image distribution industry. This article attempts to introduce the reader to various standards and parameter descriptions that influence the workflow and output.
Recognized Standards Eighty years ago, the American National Standards Institute (ANSI) was created as a non-profit organization to coordinate the development of the national standards that the United States spontaneously developed. The organization currently has 1,300 member companies, 35 government offices and more than 260 technical, trade, labor and consumer groups.
ANSI has the following four basic functions:
· Promote the development of U.S. standardization policies · Authorize developers of national standards to ensure the consistency of national standards systems and harmonize opinions.
Promoting U.S. Standardization Benefits Worldwide • Providing Information and Training on Standardization ANSI itself does not draft standards, but rather acts as a fair agency providing services to confirm whether technical experts' research results are widely accepted. It also ensures that the standard sorting groups start the democratization process, and that each person who may be affected by the standard can comment on the development effectiveness of the standard. ANSI assures users that only those rules that meet the consensus of the majority of people can survive as standards.
The Committee for Graphic Arts Technologies Standards (CGATS) is an agency authorized by ANSI. The CGATS Executive Committee is responsible for planning and coordinating the eight subsidiary subcommittees: SC1 - Terminology, SC2 - Printing Plates, SC3 - Density Metering, SC4 - Process Control, SC5 - Material Handling, SC6 - Digital Advertising Exchange, SC7 - data exchange, SC8 color definition data. This work was originally undertaken by the ANSI IT8 committee and is now the responsibility of the CGATS's governing body.
International Standardization Organization (ISO)
The Technical Committee 130 (TC 130 for short) (Image Technology) develops international standards for the printing technology industry. US Technical Advisory Group (US TAG) and TC 130 are made up of industry experts and provide ANSI with guidance on the development level of related international standards for printing technology in the United States.
The ISO TC 130 consists of five working groups: WG1 - Terminology, WG2 - Prepress data exchange (divided into two subgroups, first group TIFF/IT, second group PDF/X), WG3 - Process Control and related measurement, WG4 - carrier and raw materials, WG5 - safety and human biological engineering.
There are many recognized standards in the industry that cannot be enumerated here. To find a complete list of standards, visit the NPES (The Association for Suppliers of Printing, Publishing and Converting Technologies, Print and Paper Processing Technology Supplier Association) website. The main role of NPES is to serve CGATS, ISO TC 130, and ICC (The International Color Consortium). Copies of various standards can be ordered through the website.
Parameter description - SNAP, GRACoL, SWOP!
The parameter description is entirely another case. SNAP--Specifications for Newspaper Advertising Production was first published in 1984 and has been revised many times. The most recent amendment was in 2000. SNAP is specifically designed to improve the quality of reproduction of newspaper production and provide guidelines for information exchange. It focuses on advertisers, advertising agencies, publishers, prepress management personnel, material suppliers, and business and newspaper printing companies. This parameter describes proofing and coldset (also called non-thermosetting) printing processes suitable for all web newspaper production, including lithographic offset printing, direct offset printing, embossed printing, and flexographic printing, which can be used to print a variety of printed materials. Production, such as newspapers, pre-printed advertising inserts, and other printed finished materials. SNAP is not a specification for magazines, catalogs, packaging, or direct mail printing, nor does it address sheetfed, gravure, or thermoset web offsets.
SWOP - Specifications for Web Offset Publications was first published in the mid-1970s, specifically for the publishing industry. The initial parameter description has now been revised eight times and the SWOP commentary committee will meet regularly. The most recent version was announced at the Digital Distribution of Advertising for Publications (DDAP) seminar in February 2001. This latest ninth edition of the "New Millennium 2001 SWOP" focuses on the current digital workflow.
In order to continuously improve the quality of publishing and printing, SWOP continues to improve the parameter standards and guarantees by providing parameter descriptions for each participant of the printing technology production process (including all forms of magazine advertising and editorial input, whether analog or digital). A certain range of tolerances. In 1999 SWOP's ideas changed, and it was found that it was very important to monitor the performance of various proofing systems that existed in the market, and to determine which systems could produce SWOP-compatible proofs. The 2001 version listed some of the challenges posed by the wider use of digital files with special parameters that have reduced these problems.
The main goal of the SWOP is to explain the necessary parameters to ensure the quality of advertising in publications.
GRACoL 4.0—General Requirements for Applications in Commercial Offset Lithography is the fourth version of this reference tool in the industry. These guidelines were originally initiated in 1996 by a special working group of the Graphic Communications Association (GCA), organized with the support of the International Prepress Association (IPA) and GATF representatives. It aims to provide a universally recognized standard for commercial printing systems and production processes. The purpose of the GRACoL project is to establish a good communication relationship between the printing company and its customers by introducing clearer language and expectations into the entire printing process. This goal has not changed. The redesigned GRACol 4.0 is not only easier to read and understand, it also adds many information that reflects the industry's response to technological changes. In this case, GRACoL 4.0 has been extended to digital technology for the entire print production process. If you have to combine digital technology with offset printing, GRACoL 4.0 will tell you what to know.
DDAP—Digital Distribution of Advertising for Publications has recently signed a contact agreement with SWOP and the Digital Ad Lab to collaborate on “best practical experience†in the industry. DDAP is an industry-leading printing technology group organization that promotes "exchange of digital advertising worldwide through open program integration and recognized standards."
