Title: Re: grayscale settings for offset printing
You can create a reference file in a simple text editor (just look at the format of any reference file by opening it in a text editor). GM have a cool little unsupported application called Colorlab which will create a tiff file from a text reference file in the right format for your measuring device. It can also “chaotify” both. The QTR download (shareware $50) has in it the QTR Create ICC application and reference and tiff files for 21 and 51 step targets. I have made my own for 101 patches. Hope that helps.

QTR doesn't yank it from anything other than a printed target. Design a
target of x patches and also its associated reference file. Print it and
measure it in the same way as one would for colour. If you peep inside
you'll see it uses the A2B/B2A out curves to allow a greater number of
observations but still keep the profile size down. By using these tags
rather than a kTRC one can get colour soft proofing. So if I print with a
toned workflow (say toned quads or Epson Adv B&W) I get luminance management
only PCS->Device and full colour proofing from Device->PCS. I am not
familiar with Colorsynergy.
Dear Steve,
I've been looking for a solution for this myself. Would you mind sharing which or what software could create the target and reference files for grayscale please?
Lindsay.
