INTRODUCTION

The NBS-MCCA Collaborative Reference Program for Color and Appearance is

sponsored by the Manufacturers Council on Color and Appearance and the

National Bureau of Standards. Four times per year, paint chip samples and

near white paper samples, along with a white calibration check sample, are distributed to participating laboratories. Participants in the paint chip

test receive two pairs of color samples (from the full color spectrum)

along with a white calibration samples. Participants in the near white

paper test receive two sets of eight near white papers along with a white

calibration sample. Laboratories can participate in either or both tests.

The samples are tested by the laboratories and the data is returned to NBS

for analysis.

Each test is analyzed in both X,Y,Z and L,a,b color spaces. The X,Y,Z

space analysis is primarily for spectrophotometers while the L,a,b space

analysis is primarily for colorimeters. A laboratory must specify in which

space it wishes to receive its analyses.

Data from each laboratory is processed in a "normal" and an "adjusted"

analysis. In the "normal" analysis, the laboratory's data is used as reported. In the "adjusted" analysis, the laboratory's data is first

adjusted using a correction factor generated from the laboratory's white

calibration sample data (see Explanation of Data For White Sample).

For comparison purposes, a plot of the spectrophotometric curves of single

paint chip specimens was provided by Hemmendinger Color Laboratory,

Belvedere, New Jersey.

If there are any questions on the notes, analyses, or the report in

general, contact Jeffrey Horlick or Thomas Cummings on (301) 921-2946.

KEY TO TABLES

MEAN - The average of individual test determinations.

GRAND MEAN - (GR. MEAN)The average of the individual laboratory MEANS,

excluding laboratories flagged (see column F)

with an X, #, or +.

SD OF MEANS - The standard deviation of the laboratory MEANS

about the GRAND MEAN: an index of the amonglaboratory precision.

INST CODE - Code for instrument type and color space used

to report measurements, see Table of Instrument

Codes

F - Flag, is based on AE column with the following meaning:

0

- Included in grand mean analysis.

* _ Included in grand means but results are between

two and three standard deviations. The participants

should take this as a warning to reexamine testing

procedures.

X

- Excluded from all calculations because AE is beyond

(3) standard deviations.

+ - Excluded from all grand mean calculations because

lab is using a nonstandard instrument or test method.

#

- Excluded from all grand mean calculations because data were not understood, data were extreme, late, or insufficient information was supplied concerning instrument

and test method used.

Note: In addition to flag (F) based on delta E column, it is also possible

to have either an X or an * on individual MEANS as follows:

X - following a MEAN signifies that the mean is greater than 3 SD of MEANS

from the Grand Mean. The values for this laboratory have been

omitted in the calculations involving the MEAN for the column.

* - following any of the MEANS signifies that the quantity is greater

than 2 but less than 3 of the appropriate standard deviations from

the corresponding average. The participant should take this as a warning to reexamine his testing procedures.

AE - Total color difference between two samples. In X, Y, Z analysis it is

calculated in MacAdams (FMC II) units. For L, a, b analysis it is

calculated in Hunter units.

AE Calculation

AE is calculated in the Color and Color Difference Collaborative

Reference Program by the FMC2* equations (X, Y, Z analysis) as follows

The yellow-blue chromatic difference is

AC] = K-,S(PAP + QAQ)/bD2 - KlAS/b;

the lightness difference is

AL = 0.279K2(PAP + QAQ)/aD;

and the red-green chromatic difference is

aC 3 = K](QaP - PAQ)/aD.

The quantity, D, is an abbreviation,

D = (p2 + q2 )h.

EXPLANATION OF DATA FOR WHITE SAMPLE FOR PAINT CHIPS

Specimens of a white calibration sample (Paint Chips) were distributed to the

participants along with the usual two pairs of colored specimens, and each

participant was asked to return measurement data for the white calibration

sample (Paint Chips), reporting results in the same manner as for the colored

specimens

.

As a first step, three laboratories were selected to serve as "reference"

laboratories for the purposes of this analysis and the average of their

X, Y, Z values for the white sample were computed. Next, the ratios of

the participants data to the combined reference laboratory values were calculated for each participant (transformed to X, Y, Z space if necessary).

These ratios are shown in the White Sample Analysis tables.

Two observations can be made about the data in the White Sample Analysis

tables. First, the participants as a whole tend to be high compared with the

combined average values obtained by the selected reference laboratories.

Second, a few participants had noticeably extreme values for one or more

of the components and these participants especially should look to the cause.

Next, the ratios in the White Sample Analysis tables were used to "adjust"

the data of the normal data tables to obtain the adjusted data table values.

The adjustment consisted of dividing the X, Y, Z values of the normal data

tables by the respective ratios in the White Sample Analysis tables.

The significant change is the adjusted data tables is in the SD OF MEANS.

Comparison of these among-laboratory standard deviations with those in

the normal data tables, shows considerable reduction for X, Y, Z. Thus

part, at least, of the disagreement among participants is due to errors in

standardization that could be corrected through use of an agreed-upon white

standard. There is no similar significant change for AX, aY, and AZ.

EXPLANATION OF DATA FOR WHITE SAMPLE FOR NEAR WHITE PAPERS

Specimens of a white calibration sample (Paint Chips) were distributed to the

participants along with the two sets of eight near white paper, and each

participant was asked to return measurement data for the white calibration

sample (Paint Chips), reporting results in the same manner as for the near

white papers.

As a first step, three laboratories were selected to serve as "reference"

laboratories for the purposes of this analysis and the average of their

X, Y, Z values for the white sample were computed. Next, the ratios of

the participants data to the combined reference laboratory values were calculated for each participant (transformed to X, Y, Z space if necessary).

These ratios are shown in the White Sample Analysis table.

Two observations can be made about the data in the White Sample Analysis

tables. First, the participants as a whole tend to be high compared with the

combined average values obtained by the selected reference laboratories

.

Second , a few participants had noticeably extreme values for one or more

of the components and these participants especially should look to the cause.

Next, the ratios in the White Sample Analysis tables were used to "adjust"

the data of the normal data tables to obtain the adjusted data table values.

The adjustment consisted of dividing the X, Y, Z values of the normal data

tables by the respective ratios in the White Sample Analysis tables.

The significant change is the adjusted data tables is in the SD OF MEANS.

Comparison of these among-1 aboratory standard deviations with those in

the normal data tables, shows considerable reduction for X, Y. Z. Thus

part, at least, of the disagreement among participants is due to errors in

standardization that could be corrected through use of an agreed-upon white

standard. There is no similar significant change for AX, aY, and aZ.

IS. ABSTRACT (A 200-word or less [actual summary of most significant information. If document includes a significant bibliography or

literature survey, mention it here.)

Collaborative Reference Programs provide participating laboratories with the means for checking periodically the level and uniformity of their testing in

comparison with that of other participating laboratories. An inmportant

by-product of the programs is the provision of realistic pictures of the state

of the testing art. This is one of the periodic reports showing averages

for each participant, within and between laboratory variability, and other

information for participants and standards committees.
