A specific file format is used to specify the Status T density measurements of a patch page for importing CMYK data into Calibrator. The format has a number of requirements.

• The file format is ASCII.

• The first line must be #!EFI 3.

• In between the first line and the data, there must be the line type: 1DST.

• For the data, there must be five numbers per line, separated by one or more spaces, in this order: Percentage of toner/ink, Cyan measurement, Magenta measurement, Yellow measurement, Black measurement.

• The percentage is expressed as a decimal number (such as 0.5 or 0,5 for 50%).

• A measurement must be between -0.1 to 3.0 (inclusive)

• The first line of data must contain the measurements for the 0% sample, the last line must contain the measurements for the 100% sample, and the percentages of the lines in between must increase from lowest to highest.

• No more than 256 lines of data are allowed.

• Comment lines must start with a pound sign (#) followed by a space. A comment must be on a line by itself.

The measurement data is treated as absolute and is adjusted to become paper-relative by subtracting the density values of the first line from the remaining patches.

Example:
