New Tile Standards Developed History of these Tile Sets Early in 2006 Mt. Baker Research began developing new transfer standards produced from commercial monochromatic ceramic tiles. We evaluated the tiles distributed in North America by more than 20 international manufacturers and acquired several hundred samples. After selecting the best varieties, we purchased the 8,000 tiles that make up our present production inventory. Dr. Art Springsteen (Avian Technologies L.L.C.) supported the project by measuring reflectance factors for more than 100 glossy tiles. Dr. Jack Root performed the background research, analyzed and documented the reflectance factor data, and developed the procedures used to manufacture the standards. At present he oversees production, which is carried out at Mt. Baker Research L.L.C. The sets described here are available for distribution, but this remains a work in progress. We have commissioned several experts to evaluate our standards. We also plan to calculate nominal CIELAB color coordinates and to measure thermochromism on key glossy tiles. Overview of Sets The collection of glossy standards described in this catalog includes the following sets: Basic Colors, Special Colors, and Grey and Pastel Colors. All sets contain 16 tiles, each mounted in a Delrin holder, and each with an active optical surface measuring approximately 50 mm by 50 mm. The tiles are identified with a label placed inside the positioning device on the back of the holder. The standards are boxed and enclosed in non-contaminating, non-woven optical component envelopes. All sets include a booklet with ‘typical’ (8°/hemispherical) reflectance factor data. Calibration is available, traceable to NRC/NIST at (8°/hemispherical) geometry. We expect to be able to offer traceable calibrations for (0/45) radiance factor by September of 2007. Please contact Avian Technologies for the cost of calibration. We are actively developing matrices of color tiles for calibrating instruments with small spot size. In addition, we offer individual tiles in both standard and custom sizes. Over the next year we will publish spectral data for all of our available tiles. Our spectral palette includes several hundred colors. These tiles are available on a custom basis. We offer these sets as an inexpensive, yet more expansive, alternative to the CERAM tile sets. Please contact Avian Technologies for pricing and to let us know how we may best meet your needs. For a complete description of the history and development of these tiles, as well as >plots of spectral reflectance data for all three sets, download this PDF.
	Set #1 — Basic Colors The basic colors set parallels the CERAM Series II tiles set with a few changes. Both a white and a black tile are included, as well as a difference blue and a difference yellow pair in place of the CERAM difference green pair. The set contains sixteen tiles: 5 achromatics and 11 chromatics. Part No. ATBC-16-02-u (uncalibrated) Part No. ATBC-16-02-c (calibrated) More information on the Basic Colors Set
	Set #2 — Grey Scale and Pastel Colors The grey scale and pastel colors set extends the range of the basic color set by adding a wide range of grey scale, including a difference 50% grey pair. In addition, the set includes a wide range of pastel tiles, which are based on the more saturated colors in the basic colors set. This set contains 7 achromatic tiles and 9 chromatic tiles. Part No. ATGP-16-02-u (uncalibrated) Part No. ATGP-16-02-c (calibrated) More information on the Grey Scale and Pastel Colors Set
	Set #3 — Special Colors The special colors set offers a wider gamut of saturated colors to enhance the basic colors set. These tiles offer colors that are not normally found in color tile sets, including a deep violet difference pair and a deep brown. This set is especially strong in the purple to violet range. It aims to extend the gamut of the CERAM Series II set. Part No. ATSC-16-02-u (uncalibrated) Part No. ATSC-16-02-c (calibrated) More information on the Special Colors Set
