Rev. 1.05 - 06/2014

1OVERVIEW

Thank you for purchasing the Eoptis' CLM-194, a handheld digital tristimulus colorimeter. The CLM-194 is a handheld

compact device for colorimetric detection with a reliability higher than human eye and at a competitive price. Colour

measurements can be performed on the surface of a wide range of matte and glossy materials, thanks to a (45°c:0°)

measurement geometry and the very uniform illumination provided by integrated LEDs. Long-term stability reduces

the need of calibration by the user. The device is powered and interfaced through a USB port using a standard PC or

laptop with a Microsoft Windows operating system.

After having performed the measurement of the sample of interest, the application software allows you to:

evaluate the colour difference from a reference patch, to determine whether a sample is within a user-defined

acceptance limit

classify samples among a set of selected colours, in order to group them in classes with homogeneous colour

and improve uniformity

find the best match of the sample, looking up a colour database to reproduce the measured colour.

The colour database is encoded in software, avoiding the use of bulky physical sample libraries. Colour sets such as

RAL are included as standard and a custom or application-specific colour database can be added by the user or with

Eoptis's support on request.

3COLORIMETRY BACKGROUND

This section provides you with useful information about colorimetry and how to get the best results from the system

in real world applications.

3.1 MEASUREMENT GEOMETRY

The CLM-194 colorimeter is designed to measure the samples the way the human eye does in the real world. It

implements a (45°c:0°) geometry, that uses 45° circumferential illumination by means of multiple directional sources

and 0° viewing perpendicular to the sample plane, according to ASTM E 1164. The circumferential illumination is

essential to achieve repeatable measurements on directional and structured surfaces.

The (45°c:0°) instrument is capable of specular excluded (SPEX) readings, that exclude the specular or gloss

component from measurement. The (45°c:0°) geometry simulates the normal condition used for colour evaluation,

where a difference in gloss and texture o a sample with same pigmentation results in a difference in colour. A gloss

sample is indeed visually judged darker by the eye when compared to a matte or structured sample.

Several applications require agreement between measurement and visual assessment, therefore implicitly assuming

the (45°c:0°) measurement geometry:

batch to batch comparison in production and quality acceptance

assembly of multi-component products using different materials

printed materials and the graphic arts industry, where a (45°c:0°) is the conventional measurement geometry

reproduction of the colour of a sample taking into account texture and gloss

and many others.

If only the pigmentation difference is to be detected or different textures of the same material are to be compared, a

specular included geometry (SPIN) that includes the gloss components in readings is recommended. This is usually

achieved with (d:8°) sphere geometries.

Note that only measurements taken under the same conditions can be compared. Measurements taken with (45°c:0°)

and other geometries match only under a very limited set of conditions and often exhibit differences of several E

units.

Relevant conditions affecting measurements are:

measurement geometry

illuminant / observer pair

colour system

sample preparation and orientation.

3.2 SAMPLE PREPARATION

An ideal sample to achieve repeatable and accurate colour measurements with a reflectance colorimeter like the CLM-

194 has the following characteristics (see also ASTM E1164):

a flat surface

completely opaque with no translucency

clean and dry

uniform across the area being measured

large enough to cover the instrument's sample port

its colour is not affected by light (photochromic), moisture (hygrochromic) or heat (thermochromic)

it adequately represents the material or parts under evaluation.

If any of these qualities is not present, the sample must be made as ideal as possible for a correct measurement.

Rev. 1.05 - 06/2014

Translucency by a non-opaque sample is often the main source of error. Part of the light incident on a translucent

sample penetrates the surface and undergoes internal scattering and lateral diffusion, which reduces the intensity of

reflected light. Ambient light might also penetrate the instrument port and affect the measurement in an uncontrolled

way. A translucent sample must be made as opaque as possible either by increasing the thickness and/or by backing it

with an stable and durable opaque material (usually black or white). The chosen thickness and baking material should

be logged in measurement report to ensure repeatability.

To select a sample which adequately represents the part under evaluation, examine a sufficient number of random

samples from the lot, and average the readings.

In case of an uneven surface, the instrument optically averages the colour on the area corresponding to the

measurement spot. For longer range non-uniformities, it is recommended to average several measurements taken at

different positions on the sample to find the closest match (see the Multiple Acquisition feature in §5.9.3).

Textured surfaces can be presented to the instrument at any orientation. The circumferential illumination allows

reading which is unaffected by sample orientation. In very limited cases where the surfaces are highly textured, it is

recommended to turn the sample and check differences on multiple readings.

Several published standards address sample selection for various industries (fibers, yarn, liquids, powders, coatings,

paints, papers, leather, etc...). Contact Eoptis for additional information and support in identifying the best technique

to exploits the full performance of the colorimeter.

Repeatable and accurate measurements may be difficult or impossible to obtain if some samples have any of the

following characteristics:

a surface which contains fluorescent pigments or appears unusually bright

an appearance which changes based on the point of view (may contain metallic, flake, or pearlescent

colorants)

a very curved, highly uneven or corrugated surface.
