我现在已经有这个问题了。接近我的“校对”脚本的末尾，InDesign中当前打开的文档将导出为两个不同的.pdf文件。第一个是密码保护，而第二个不是。我似乎对后者没有任何问题，但前者经常以某种方式被破坏，并且不能由任何PDF阅读器打开，包括Acrobat本身。这是导出的代码块（不可单独运行，顺便说一下）：
/********** BEGIN PDF EXPORTING **********/
// First, let's create and set PDF export preferences.
// This begins with creating a temporary preset if it doesn't already exist.
// This preset will be used for both the Proof page and the Cover sheet.
var tempPreset = app.pdfExportPresets.item("tempPreset");
try
{
tempPreset.name;
}
catch (eNoSuchPreset)
{
tempPreset = app.pdfExportPresets.add({name:"tempPreset"});
}
with (tempPreset)

{

}
if (currentProduct.pLabel != "")
{

}
}
currentProcess.text = "Exporting PDF proof page"; progressWin.show();
progressIndividual.value++; if (aProducts.length > 1) {progressOverall.value++;}
// Before exporting the Proof page(s), hide the color bar on multicolor products.
if (multiColor) {document.layers.item("COLOR BAR").visible = false;}
// Then we save the proof page.
document.exportFile(ExportFormat.PDF_TYPE, File(jobFolder.toString() + "/" + saveName + ".pdf"), false, tempPreset);
当它偶尔产生损坏的PDF时，我想也许是我们不太理想的网络结构导致问题，所以我尝试将PDF文件导出到本地硬盘驱动器而不是直接导出到网络，然后将文件移动到网络。因此，上面代码块中的最后一行替换为：
// First, to the local HDD.
document.exportFile(ExportFormat.PDF_TYPE, File("~/Documents/" + saveName + ".pdf"), false, tempPreset);
$.sleep(1000);
File("~/Documents/" + saveName + ".pdf").copy(File(jobFolder.toString() + "/" + saveName + ".pdf"));
$.sleep(1000);
File("~/Documents/" + saveName + ".pdf").remove();
为了以防万一，我甚至在那些1秒延迟中添加了。可悲的是，这没有帮助。我时不时地得到一个损坏的PDF。如果损坏的文件有任何模式，我无法辨别它。有没有人有任何想法？
答案 0 :(得分：0)
最后打击了我，如果在Acrobat中无法打开损坏的文件，为什么不在文件创建后测试？所以我创建了一个循环导出PDF文件并尝试在Acrobat中打开它。如果打开正常，则打印并关闭文件，返回“true”消息。如果无法执行此操作，则会向脚本返回“false”消息。然后循环重复，只要该消息是“假”。虽然不是一个很好的解决潜在原因（无论它可能是什么），但它至少是一个解决方案，可以很好地满足我们的需求。诀窍是，因为我们使用Mac，我们必须通过AppleScript路由消息，而不是使用BridgeTalk直接与Acrobat通信。
以下是主要InDesign脚本中的代码片段，它通过PDF检查循环：
// Then we save the proof page.
// The loop is to make sure that the file was saved properly.
var validFile = false; // Flag that states whether or not the file is corrupted after saving.
var rString; // String returned from Acrobat that should be either "true" or "false".
var testAndPrintFile = File("~/Documents/testAndPrint.applescript"); // The applescript file that calls Acrobat and runs a folder-level script.
var pdfFile; // A String of the filename & path that will be passed to through the applescript file to Acrobat.
var pdfArray = new Array(4); // An array to send to Acrobat. [0] is the PDF filename as a String,
// [1] is duplex if true, [2] is the printer name, and [3] is to enable printing.
if (multiTwoSided || twoPages) pdfArray[1] = "true";
else pdfArray[1] = "false";
pdfArray[2] = localPrinter;
pdfArray[3] = "true";
while (!validFile)
{
$.writeln("If this message is seen more than once, then the Proof PDF was corrupted.");
try
{
document.exportFile(ExportFormat.PDF_TYPE, File(jobFolder.toString() + "/" + saveName + ".pdf"), false, tempPreset);
}
catch (e)
{
alert("Could not save the Proof PDF. Please close any open copies of the Proof PDF, then save and print it manually.");
}
pdfFile = jobFolder.toString() + "/" + saveName + ".pdf";
pdfArray[0] = pdfFile;
$.writeln("pdfArray contains: " + pdfArray);
try
{
rString = app.doScript(testAndPrintFile, ScriptLanguage.APPLESCRIPT_LANGUAGE, pdfArray);
validFile = rString == "true";
// validFile = true;
$.writeln("validFile is " + validFile);
if (!validFile)
{
alert("It seems that the file " + unescape(pdfArray[0]) + " is corrupted. Will try to export it again.");
}
}
catch (e)
{
$.writeln("ERROR at line number " + e.line);
$.writeln(e.description);
throw new Error("ERROR at line number " + e.line + "\n" + e.description);
}
}
此循环调用的testAndPrint.applescript文件：
set pdfFile to item 1 of arguments
set duplexed to item 2 of arguments
set printerName to item 3 of arguments
set printEnabled to item 4 of arguments
tell application "Adobe Acrobat Pro"
set result to do script ("testAndPrint(\"" & pdfFile & "\", \"" & duplexed & "\", \"" & printerName & "\", \"" & printEnabled & "\");")
end tell
return result
最后，当Acrobat启动时加载到内存中的文件夹级Javascript文件，准备将其函数调用到上面的Applescript文件中：
var testAndPrint = app.trustedFunction(function (fName, duplexed, sPrinterName, bEnablePrinting)
{
var success = true;
app.beginPriv();
console.println("fName is " + unescape(fName));
console.println("sPrinterName is " + sPrinterName);
try
{
var printDoc = app.openDoc(unescape(fName));
var pp = printDoc.getPrintParams();
if (duplexed == "true") pp.DuplexType = pp.constants.duplexTypes.DuplexFlipLongEdge;
else pp.DuplexType = pp.constants.duplexTypes.Simplex;
pp.printerName = sPrinterName;
pp.interactive = pp.constants.interactionLevel.silent;
pp.pageHandling = pp.constants.handling.none;
if (bEnablePrinting == "true") printDoc.print({bUI: false, bSilent: true, bShrinkToFit: false, printParams: pp});
printDoc.closeDoc(true);
}
catch (e)
{
console.println("ERROR at line number " + e.lineNumber);
console.println(e.message);
success = false;
}
app.endPriv();
console.println("success is " + success);
return success;
});
我希望这些信息可能对遇到类似问题的其他人有用。当然，它并不漂亮，但它确实完成了工作。
