Importing density measurements
This appendix describes Simple ASCII File Format, which can be used to import density measurements from measurement devices. To use your own measurement data from an alternate measurement instrument, record your individual readings in a text file and structure it as follows.
Simple ASCII Import File Format (SAIFF)
This format describes Status T measurement data for import into the ColorWise Pro Tools Calibrator. The three possible file formats are:
•1D Status T density for EFI 34 patch page
•1D Status T density for EFI 21 patch page
•1D Status T density for other pages (maximum of 256 patches per ink)
The file format is ASCII and has no tabs. A single space or multiple spaces are used as delimiters. Blank lines are not allowed. Each line in the file represents four patches (C, M, Y, K) of a specific ink value. Comments may be on any line in the file, and these lines start with a pound sign (#) followed by a space. A line with a pound sign followed by any character other than a space has been reserved. Comments must be on an entire line by themselves.
Each line of data contains five values. The first number is the sequential patch number (for EFI 34 and EFI 21 pages) or the ink value percentage (for other pages). The four values that follow are the density values of C, M, Y, and K of the corresponding patch. Lines are ordered either by increasing sequential patch numbers, or by increasing the ink percentage.
For Windows computers, the file extension must be .cm1. For Mac OS computers, the file type must be ‘TEXT’.
Measurement data in EFI 34 and EFI 21 are
