The GRACoL press sheet contains the IT8.7/3 and two copies of the ECI2002 Random.
DTR004 data is based on the IT8.7/3 and is readily available online at www.npes.org/standards/toolsDTR004.html. This data set provides colorimetric (LAB values) for the 928 patches of the IT8.7/3 target. The data file is a .csv file. Changing the first line of text to “IT8.7/3” will allow the file to be used in many ICC compliant programs such as Gretag ProfileMaker. I have successfully made a profile with this data file.
(Of course if you only want the CMYK dot percent reference file you know that that is available in the Gretag ProfileMaker applications folder.)
