Alternative ArgyllCMS rgb printer target for Colormunki/i1Studio

[pharmacist]

Because not everybody has specially made scanning jigs/rulers for the Colormunki/i1Studio and the standard printarg command to generate Colormunki targets produces only 210 patches in the high density patch layout, a reasonable printer target, it needs at least 2 sheets of A4 to produce a reasonable good printer profile, whereas the specially i1Pro patch layout can easily fit 480 patches on a single sheet, but the scanning needs a specially made scanning jig to ensure accurate scanning. For this I have made a primary single sheet 325 patch target (based on the work of @Ink stained Fingers and his discovery that a good printer profile is already possible with a limited patch count) by using a virtual large sheet paper to force the printtarg command to put 325 patches on a large virtual page and using PS to shrink and manipulate the layout to get a 325-patch target to be printed on a single A4 page that can be easily scanned with the help of a simple ruler to align the scanning process: 3 rows on this target has exactly the width of the Colormunki/i1Studio device, making it very intuitive to scan the target, because it needs alignment only 1 row width before the row that is to be scanned:

On the left there is a some space to fill in data like printer/ink/media setting etc for your own documentation.
There is a black line to align the ruler to in order to get the first row A to be scanned by the Colormunki/i1Studio.

This is how the scanning process will be by moving the ruler just 1 previous row width from row A to M:

Below the corresponding patch set to print the target and generate the profile using the makeprofile.bat batch file in a DOS-box.

Nice work! The patch size is interesting! Is there any particular printtarg commands you used for this chart? With all the experimenting we've done lately, I'm at the point where I just simple do a one page chart with preconditioning. I would love to reproduce something similar for letter sized paper.
