    Hello again,

    I’m writing a tool that lets you create and set on page swatches of any size and different shapes.
    It’s mainly to do mixed inks for use with the Xerox Iridesse Press, but you could create a Pantone Book with it I guess.

    I’ve achieved so far, thanks to the help of others, the ability to create a bunch of mixed inks and create the rectangles on the page.

    I would to create groups for mixed inks, to tidy things up a little.
    I don’t know.

    I’m not yet a good enough programmer to figure it out from this webpage: https://www.indesignjs.de/extendscriptAPI/indesign-latest/#MixedInkGroups.html

    Anyone can help me thank you!

    Hello,

    MixedInkGroups.add lets you generate multiple mixed inks (from a combination of inks), as done in UI by Swatches > New Mixed Ink Group.

    inkList – inks to use to create the mixed inks
    inkPercentages – Array of initial percentages for each ink from inkList
    repeatValues – Array of repetitions for each ink
    incrementValues – Array of increments to use when repeating

    For example,
    [Proces Cyan, PANTONE 281 C] with percentages [0, 0], repeatValues [2, 2], ad increments [10, 10] would create (2 + 1) x (2 + 1) = 9 mixed inks.

    Cyan %, PANTONE 281 C %
    (0, 0)
    (0, 10)
    (0, 20)
    (10, 0)
    (10, 10)
    (10, 20)
    (20, 0)
    (20, 10)
    (20, 20)

    Hope this helps.

    At the bottom of that page you can see that this object is used in both Application (adding one in there adds it to the default set of swatches), and Document.

    Presumably (untested) you can use

    myMixGroup = app.activeDocument.mixedInkGroups.add (... your parameters here ..)

    and then use that variable where you wish.

    Wow! Thank you for replying.

    Here’s a link if you want to take a peek :)

    Here’s also my working code for swatch generation.

    If I change my code to mixedInkGroups instead of mixedInks
    It adds some weird looking duplicate (I’m sorry never seen this, don’t know what they are).
    Look here: https://imgur.com/cq5kaF3

    I want to generate the mixed inks but add them to a color group.
    Maybe I’m misunderstanding what a mixedInkGroup is???

    THANK you for your time !!

    Yes, MixedInkGroups and ColorGroups are different things.
    To add a mixed ink (or any swatch for that matter) to a ColorGroup, you can do:

    var mixedInkSwatch = // as created in your code
    app.activeDocument.colorGroups.add(“My Mixed Inks”, [mixedInkSwatch]);
