Introduction

The ACM SIGGRAPH organization - the organization itself, the annual conference, and all other sponsored events and activities - now has a unified graphic identity. This unified graphic identity will help to strengthen the ACM SIGGRAPH name and image through a consistent branding, a distinctive mark used throughout all of our events, publications, and activities.

This document defines our logo use policy, describing the logo in clear terms, and then defining general classes of acceptable and prohibited use. It does not attempt to define every imaginable use of the logo, however, but provides a clear path to seek approval for variations on the standard logos.

The ACM SIGGRAPH organization logo and the ACM SIGGRAPH annual conference logo are registered trademarks of the Association for Computing Machinery, Inc. ("ACM") These logos are valuable legal and intellectual assets, and unauthorized use of these logos is prohibited.

Questions regarding this policy should be directed to the ACM SIGGRAPH President.

The Logo

The basic ACM SIGGRAPH logo consists of two parts: the graphic element and the text element.

The graphic element is a pair of interlocking partial spheres (see Figure 1). The space between the two pieces forms a stylized "S," alluding to the "S" in the "SIGGRAPH" name. The partial spheres can be represented in either two or three dimensions.

Figure 1: ACM SIGGRAPH organization logo.

The text element's content will vary by application (e.g. ACMSIGGRAPH or SIGGRAPH2005), but it will be set in a specific typeface (Helvetica Neue and Helvetica Neue Bold), and the proportion of the text size to the graphic element should remain the same. "SIGGRAPH" is set in bold, and "ACM" or the conference year is set normally. No space is used between "ACM" and "SIGGRAPH," or between "SIGGRAPH" and the conference year, as the use of differing typeface weights implies a space.

Groups associated with the organization or annual conference that use the logo should follow the appropriate example, above, when preparing a text element for their specific logo.

The graphic and text elements may be arranged side by side or with the graphic element centered above the text element (see Figure 2).

Figure 2: Variations on ACM SIGGRAPH organization logo.

Proper use of the logo will incorporate both the graphic and text elements. It is understood, however, that certain uses of the logo preclude the inclusion of the text element. For example, use of the logo on a pin or badge, or on the spine of a book may necessitate the use of the graphic element alone. Wherever possible, however, the graphic and text elements should be used together.

Color, Texture and Background

The ACM SIGGRAPH organization logo shall use the following colors: the graphic element shall be red (Pantone PMS 646 C) and blue (Pantone 201 CVC) and the text element shall be grey (Pantone Cool Gray 8 CVC).

The ACM SIGGRAPH annual conference logo, a variation on the organization logo, will have a color palette that is selected by each year's conference committee and applied consistently on conference material. Additionally, texture may be applied to the graphic element, and if desired, a background image may be placed with the conference logo (see Figure 3).

Guidelines for Internal Use

Committees and projects of the ACM SIGGRAPH organization are free to use the organization and/or annual conference logos, provided the following guidelines are considered:

• The logo and text should be used together, as defined, whenever possible.
• The typeface shall not be altered or replaced with another.
• The proportions of logo and text shall be retained.
• It is understood that certain design opportunities necessitate the use of the logo without the text.
• Decoration of the logo is acceptable as long as the basic logo remains clearly visible.

Acceptable External Use

Entities associated with the organization or annual conference are welcome to use the organization or conference logo, as appropriate, to promote their events and/or describe their activities.

Individuals may use the logos to acknowledge their membership in the organization and/or their participation in a sponsored event.

It is also acceptable to grant permission to third parties, such as news organizations, to use the logos for promotional purposes.

Prohibited Use

It is our policy that the ACM SIGGRAPH organization logo and annual conference logo be used without modification and in an appropriate manner. Examples of prohibited use include, but are not limited to, the following:

• Any implication of endorsement by the organization or its activities;
• Commercial uses (placement of the logo on product packaging);
• An individual's use of the logo for purposes other than acknowledging membership or participation in our activities;
• Combination of the organization or annual conference logo with another logo.

Requests for Use Outside Described Scope

Requests for use of the name or logos which fall outside the scope of the policy, or proposed variations on the logo design are to be brought to the attention of the ACM SIGGRAPH President. Lack of response within two weeks can be construed as approval of the proposed use and/or variation.

Obtaining The Logos

Variations on the ACM SIGGRAPH organization logo - differing in color resolution, file format, and arrangement of the graphic and text elements - are available to download.

Variations on the ACM SIGGRAPH annual conference logo - differing in color resolution, file format and arrangement of the graphic and text elements - are available to download from each conference year's web site.
