Full title and description

Multimedia systems and equipment - Multimedia e-publishing and e-book technologies - Printing specification of texture map for auditory presentation of printed texts. This International Standard specifies the required printing quality and physical print characteristics of a texture map used to enable auditory presentation (machine decoding and spoken output) of printed texts; the texture map may be printed on paper or presented on display devices.

Abstract

IEC 62875:2015 defines the printing specifications that ensure a texture map (a bitmap-style representation used with auditory presentation systems) remains reliably readable and decodable after printing. The standard is intended to ensure interoperability between printed materials and devices or software that decode the texture map for auditory rendering; it complements the encoding/decoding and format rules defined in IEC 62665.

Scope

Specifies the printing quality of the texture map on paper (and presentation on displays) so that texture maps produced in accordance with IEC 62665 can be consistently read and decoded by auditory presentation equipment. The scope covers print resolution and sizing expectations, placement on the page, and the physical print characteristics required to support decoding and subsequent auditory rendering.

Key topics and requirements

• Printing quality requirements for texture maps (sufficient contrast, registration and fidelity to the bitmap).
• Reference print resolution and sizing guidance to ensure reliable scanning/decoding (commonly referenced 600 dpi workflows and fixed printed sizes derived from bitmap cell sizes).
• Positioning and margin requirements for printed texture maps to support consistent capture by camera/scanner equipment.
• Requirements that support interoperability with the texture-map encoding and decoding rules specified in IEC 62665 (format, control codes and error-handling expectations).
• Practical production guidance for publishers and print service providers to ensure reliably decodable outputs (paper choice, print DPI, halftone/bitmap integrity and alignment marks).

Typical use and users

Primary users include e‑publishing houses, print service providers producing accessible materials, assistive-technology vendors and device manufacturers that implement texture-map decoding and auditory rendering, and accessibility program teams in libraries or institutions that need to produce interoperable print materials for visually impaired readers. The standard is used to ensure printed texture maps can be scanned or imaged and correctly interpreted by auditory-presentation equipment.

Related standards

IEC 62875:2015 is directly linked to IEC 62665 (Texture map for auditory presentation of printed texts) which specifies the encoding, shape, dimensions and decoding behavior of the texture map; IEC 62875 provides the complementary printing-specification requirements to ensure the IEC 62665 texture map remains decodable when printed. National and regional adoptions (EN/IEC variants) exist under EN 62875 / EN 62665 and related national documents.

FAQ

Q: What is this standard?

A: IEC 62875:2015 is an international standard that defines the printing specification for a texture map used in auditory presentation of printed texts — i.e., the print-quality requirements that ensure a texture map can be reliably scanned and decoded for spoken output.

Q: What does it cover?

A: It covers physical print characteristics, recommended resolution and size guidance, placement/margins on the page, and other print-quality requirements needed to ensure texture maps conforming to IEC 62665 remain decodable after printing.

Q: Who typically uses it?

A: E-publishers, print service providers, assistive-technology vendors, device manufacturers, integrators and accessibility teams in libraries or educational institutions—any organization that needs printed materials to be interoperable with auditory-presentation systems.

Q: Is it current or superseded?

A: As published by IEC, IEC 62875:2015 is the 2015 edition and is listed as active; the IEC product record shows a stability date (targeted stability) through 2028. Users should check IEC product lifecycle notices for any later revisions.

Q: Is it part of a series?

A: Yes — it is functionally paired with IEC 62665 (the texture-map encoding and decoding standard). IEC 62875 provides the printing-specification complement to the encoding/decoding rules defined in IEC 62665; national (EN) adoptions of these documents are available.

Q: What are the key keywords?

A: texture map, auditory presentation, printing specification, e-publishing, accessibility, decoding, IEC 62665, DPI, print quality.
