Introduction

Luminex licenses its core technology to many leading companies in different subsegments within the life sciences industry. Our partners leverage the multiplexing capabilities of Luminex’s xMAP* solution against competing single-plex and multiplexed technologies. Through consistent and cooperative branding, Luminex and our partners can maintain and enhance the strength of the xMAP message and collectively increase the entry barrier for competing technologies.

The xMAP brand is reflected every time we communicate with the marketplace. From the logo to the Luminex web site to all of the various xMAP-related marketing materials, the key to effectively communicating the brand is consistency.

The graphic standards and guidelines presented in this document serve as a tool for ensuring that a clear and consistent presentation of the Luminex and xMAP brand identities are sustained throughout all forms of communication. Strictly following these standards and guidelines is paramount to maintaining the integrity of these brands in the marketplace.

The xMAP logo must be used in media where Luminex xMAP technology is incorporated into the product and any of the following are mentioned:

	•		Multiplex (or other forms of this word — i.e. multipara-meter, multiplexing, multiple tests, bead array, etc.)
	•		Microspheres (or other similar reference to the microspheres — i.e. beads)
	•		xMAP
	•		Luminex

Proper Usage of the Logos

All logo artwork/files will be provided to you by the Luminex Marketing Department. With the exception of size, this artwork should not be altered in any way, recreated or scanned in from another document.

Available File Formats

Luminex anticipates that the xMAP logo will be used in different media — web sites, signage, or corporate collateral. As a result, the following file formats are available:

	•		EPS. This is the most popular and recommended format because it is resolution independent and scales well. It should be used for any collateral that is to be printed — either commercially or from a desktop printer.
	•		JPEG. This format is preferred for PowerPoint and other computer-based presentations. A majority of programs will read JPEGs, but is not intended for high-quality reproduction. Scaling of JPEGs is not encouraged.

Four-color logo

Black and white logo

Footnote

The xMAP^® medallion and xMAP^® logo are trademarks of Luminex Corporation

It is our belief that the xMAP brand transcends Luminex. As such, it can be effectively incorporated into a partners’ awareness campaign without detracting from the partner branding. In an effort to create consistency, these guidelines primarily focus around the use of the xMAP medallion logo, pictured left. This medallion is the cornerstone of these branding guidelines.

The xMAP medallion is to be used in all types of print media. For use on OEM products, see page 5.

There are two versions of the logo medallion. The number of colors should be consistent with the colors in the application (i.e. four-color, two-color [see page 5], or black and white.) The four-color version of the medallion is always preferred, but in situations where color cannot be used, the black and white version is acceptable.

Always use the footnote stated in each piece of print material excluding advertisements.

Background color

It is acceptable to place the logo on a white, black or color background Avoid placing the medallion on a background where the logo would not be legible

Area of isolation

The space around the logo shall be equal to the height of the “x” in xMAP

Size of logo

The minimum size of the logo in all print shall be 1 5” wide If you encounter a size restraint, please contact the marketing department at Luminex (512 219 8020) for instruction

Web

In general, follow the usage guidelines for print For specific instructions please contact the marketing department at Luminex, ▇▇▇ ▇▇▇ ▇▇▇▇

2-color xMAP logo

1-color xMAP logo

When placing the xMAP trademark on OEM products, use the xMAP logo to the left. The minimum width of the logo should be 1.5”.

The xMAP logo shall be conspicuously and permanently imprinted onto the front of the product (or on the same side of the product as the OEM’s name) unless otherwise approved in writing by Luminex. The OEM’s name shall be more prominent than the xMAP logo.

Color usage of the xMAP logo can be displayed in one, two, or four colors. Color usage should be consistent with the items on the product. For 2-color usage, the logo prints black and red (PMS 185).

If your company’s logo is smaller than the xMAP logo, please contact the marketing department at Luminex (512.219.8020) for instructions on using the logo.
