    It was sad to hear that DPR is shutting down, especially at such short notice!!!

    I checked and I have been a member there since August 2003 and though I had forgotten the name Phil Askey (mentioned by Mark above), I thought that it changed and not necessarily all in good ways following its sale to the new owners.

    Update

    I put the question to the paper supplier and the feedback was indeed that the slightly smaller would not be a problem.

    Though I did ask what scanning device/method they use and they were silent on the matter.

    Furthermore, in my email I explained about my using the Adobe Color Printer Utility and that it has been around for years 😉  Just perhaps they may reflect this (more) appropriate method over the one I copied & pasted above???

    Here is one of the three targets

    Ooooops! it looks a TIFF file won’t upload.

    But yes the screenshot shows the target.

    PS in my starting post the links to download the TIFF targets are live so you could download one to examine it ?

    Indeed, mostly under Windows, ACPU has had scaling issues but that shouldn’t be any issue unless:

    1. You are using an auto Spectrophotometer like my iSis XL and,

    2. You follow the minimum patch size from X-rite’s product for one.

    I don’t follow this, my targets are built with larger patches and unless someone doesn’t set the print driver for 100% (or expand print size), zero issues in all the years since ACPU has been out with hundreds of customers sending me targets.

    If someone isn’t using an auto Spectrophotometer, the scaling isn’t at all a factor.

    I will have to ask the paper supplier who make the custom profiles.

    The targets are 1600 patches, i1Profiler Test Chart (total of 3 off pages)

    Andrew

    I have found an apparent anomaly using the ACPU

    The TIFF chart images have a default size of 27.1 x 16.1 cm and printing from PS it prints exactly that size.  However, the ACPU even if I set the printer to print zoom to 100% always prints it approx 1 cm smaller.

    I surmise that there is a specific reason (to do with the scanning of the Charts?) that the size is important.  I find it inexplicable that ACPU will not print it the original size!

    Do you have an insight on this oddity?

    PS I found this discussion of the resizing bug being reported here Adobe® Color Printer Utility to print your targets… – Page 3 – Adobe Support Community – 3130882
    back in 2011 and you posted in that discussion saying it exists when using Windows.  So >10 years on this has yet to be addressed by Adobe…….it is like they only recognise Mac (for the purposes of  ACPU), to this day 😉 ???

    PPS in the absence of an ACPU solution I will have to ‘revert’ to telling PS to let the printer manage the colours and turning the Colour Management off in the printer driver.
