Color code for color measurement system
A color measurement system includes a hand held color measurement instrument, which may be provided with a wireless interface to a computer. The color measurement system includes a scanning guide for holding the hand held color measurement instrument in proper alignment with a color target. The scanning guide includes a calibration reference to allow convenient calibration of the hand-held color measurement instrument. The hand-held color instrument includes an illumination ring to provide visual feedback to the user. The color of the illumination ring changes in order to display a color similar to that being read by the hand-held color measurement instrument. Color management profiling of the hand held color measurement instrument illumination ring improves the color rendition capability of the illumination ring.
1 . A color code for reading by a color measurement instrument comprising a plurality of code color patches wherein data is encoded into one or more subsets of the code color patches.
2 . The color code of claim 1 further comprising a first subset containing a start bit.
3 . The color code of claim 2 further comprising a second subset containing a stop bit.
4 . The color code of claim 3 where the color code contains information regarding a color chart, the color chart having a plurality of strips, each strip containing strip color patches.
5 . The color code of claim 4 further comprising a third subset of code color patches encoded to contain a count of the strip color patches within each strip.
6 . The color code of claim 5 further comprising a fourth subset of code color patches encoded to contain a total of the strip color patches on the color chart.
7 . The color code of claim 6 further comprising a fifth subset of color code patches encoded to contain a checksum.
8 . The color code of claim 7 further comprising a sixth subset containing a size of the strip color patches.
9 . The color code of claim 8 further comprising a seventh subset containing a gap size of a gap between color patches.
10 . A color strip comprised of a plurality of color patches, the color strip capable of being measured by a color measurement instrument comprising:
a first subset of the color patches containing information about the color strip; and
a second subset of the color patches containing a target measurement strip.
11 . The color strip of claim 10 further comprising a third subset of color patches containing a start bit.
12 . The color strip of claim 11 further comprising a fourth subset of color patches, the fourth subset containing a stop bit.
13 . The color strip of claim 12 where the start bit and the stop bit contain a color overprint.
