Make sure to open Measurement Settings to select the required options and calibrate the spectrophotometer. It is important to verify that the number of patches to read matches the Scan Count, as seen in the example 6 columns.

Once your .TIFF file is printed, select the first color in the list and proceed to read the patches with the spectrophotometer. The scan counts configuration in measurement settings will maintain the reading in rows. If the window doesn't open automatically, because neoMatch was closed between the steps exporting and measuring, load the .ref text format file, which is exported together with the TIFF file.

Proceed to read the patches in rows, from first to last, in scan or spot mode. Start and stop to measure from white media. The next patch to scan will be indicated automatically, until the reading is finished. Measure in first row from left to right (A) and in second row from left to right (B).

When the process is finished, another dialog indicates you so.

With the next window the first part of the process is over, as we see what are the different values between your Color Library references and those with their actual print.

DeltaE values show the deviation between references. The smaller the DeltaE Value is, the closer is to the colors which have been read. Although this DE value can be set in the program's Preferences, by default, a difference of 3 is understood as acceptable, and further than that is not. This is why we see some of the references with a warning symbol, as they are over 3.

On the right of the window we can compare the differences in the Lab values of references, print and measurements of the color.

In case of joining 2 or more measurements in one using 'Average', Median or other methods, then you can do this from the Edit | Merge Measurements..., that opens a dialog in the document to select an average method or delta range.
