This chapter describes Simple ASCII File Format (SAIFF), which you can use 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 then 
structure the file as follows.

This format describes

 measurement data for import into the ColorWise Pro Tools 

Calibrator. The three possible file formats are:

• 1D Status T density for EFI 21 patch page

• 1D Status T density for EFI 34 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. Comment lines 
must 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 a line by 
themselves.

Each line of data contains five values. The first number is the sequential patch number (for 
EFI 21 and EFI 34 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 21 and EFI 34 are paper-relative. For other pages, if the first line 
corresponds to zero ink value, the Calibrator assumes that the measurement data is absolute 
and adjusts it to become paper-relative by subtracting the density values of the first line from 
the remaining patches.
