I've learned an enormous amount of scripting for InDesign CS6 thanks to all of the helpful folks here! Now, it's a problem with setting the printPreferences for a document. Here is the code I have:
with(document.printPreferences) {
activePrinterPreset = outputPreset;
pageRange = outputRange;
for (var j = 0; j < allInks.length; j++) {
document.inks.item(allInks[j]).printInk = false;
}
for (var k = 0; k < printInks.length; k++) {
if (printInks[k].toString() === "Black") {
$.writeln("Found Black!");
printBlack = true;
$.writeln("Set Black!");
} else {
document.inks.item(printInks[k]).printInk = true;
}
}
if (offsetJob) {
// If it's an offset job, we might need to change page sizes.
if (productType === "HI-N13W") {
paperSize = PaperSizes.custom;
paperHeight = 12.5;
paperWidth = 8.5;
} else if (productType.subString(3,5) === "PC") {
paperSize = PaperSizes.custom;
paperHeight = 8;
paperWidth = 12.5;
} else if (couldBeBothJobs.toString().indexOf(productType.subString(3,5)) > -1) {
paperSize = "US Letter";
} else {
paperSize = PaperSizes.custom;
paperHeight = 8;
paperWidth = 25;
}
}
}
In the second for loop, you'll see that I have first turned off ALL of the inks in the document for printing. I then only turn on the ones in the printInks array. If, however, the word "Black" exists in the array, there isn't an Ink for it, so instead, I want to set the built-in printPreference "printBlack". (This complements the other three—printCyan, printMagenta, and printYellow.)
It's just supposed to be a boolean value, according to the InDesign CS6 Object Model Reference. However, whenever the script gets to that point, it halts. Pasting just that small bit of code to a fresh document, just so I can see the error message, gets me this:
The property is not applicable in the current state.
What does this mean? And more importantly, how can I fix it? I know that trapping has to be off before this property can be set, but I've definitely made sure that it is off.
After asking this question on the Adobe Community Forums, I was told that some of the Print Preferences cannot be set directly on the document, but must instead be set on a Print Preset, which, in turn, is then set as the Active Print Preset. Thus, I just re-built the preset I needed and assigned it to a new, temporary one. The following is the result:
try {
tempPreset.name;
}
catch(eNoSuchPreset) {
tempPreset = app.printerPresets.add({name:"tempPreset"});
}
// Let's turn off all of the spot colors before everything else.
for (var j = 0; j < allInks.length; j++) {
document.inks.item(allInks[j]).printInk = false;
}
with(document.printPreferences) {
tempPreset.printer = Printer.POSTSCRIPT_FILE;
tempPreset.ppd = "OYO Imagesetter";
tempPreset.pagePosition = PagePositions.CENTERED;
tempPreset.paperSize = PaperSizes.CUSTOM;
tempPreset.paperHeight = "12.5 in";
tempPreset.paperWidth = "6.5 in";
tempPreset.colorOutput = ColorOutputModes.SEPARATIONS;
tempPreset.trapping = Trapping.OFF;
tempPreset.screening = "60 lpi / 600 dpi";
tempPreset.sendImageData = ImageDataTypes.OPTIMIZED_SUBSAMPLING;
pageRange = outputRange;
// Now let's turn off all of the CMYK colors.
tempPreset.printCyan = false;
tempPreset.printMagenta = false;
tempPreset.printYellow = false;
tempPreset.printBlack = false;
// Then we turn back on BLACK if it exists.
for (var k = 0; k < printInks.length; k++) {
if (printInks[k] === "Black") {
tempPreset.printBlack = true;
} else {
document.inks.item(printInks[k]).printInk = true;
}
}
// If this is a four-color process job, then turn back on all of the process colors.
if (processJob) {
tempPreset.printCyan = true;
tempPreset.printMagenta = true;
tempPreset.printYellow = true;
tempPreset.printBlack = true;
}
// That concludes OYO seps.
}
var mydpp = document.printPreferences;
mydpp.activePrinterPreset = "tempPreset";
That gets my 99% of the way to completing this script. YAY!!
