illustrator插件移除非纯黑叠印AI插件

　　1 方法原理
　　illustrator是矢量编辑软件，画板是绘制处理的重要容器，在印刷方面的一个重要功能就是移除非纯黑叠印，开发一个 移除非纯黑叠印功能 ，以下功能仅用于学习交流，请勿用于非法用途和商业用途，源代码如下所示： var doc = documents[0]; var pgItm = doc.pageItems; app.selection = null; for (var i = 0; i < pgItm.length; i += 1) {     if (pgItm[i].typename == ＂TextFrame＂) {         var fiTxtColor = pgItm[i].textRange.fillColor;         if (pgItm[i].textRange.overprintFill == true) {             if (fiTxtColor.black == 100 && fiTxtColor.cyan == 0 && fiTxtColor.magenta == 0 && fiTxtColor.yellow == 0) {                 continue;             } else {                 pgItm[i].selected = true;             }         }     } else {         var fiColor = pgItm[i].fillColor;         if (pgItm[i].fillOverprint == true) {             if (fiColor.black == 100 && fiColor.cyan == 0 && fiColor.magenta == 0 && fiColor.yellow == 0) {                 continue;             } else {                 pgItm[i].selected = true;             }         }     } } removeOVPfill(app.selection); app.selection = null; for (var i = 0; i < pgItm.length; i += 1) {     if (pgItm[i].typename == ＂TextFrame＂) {         var stTxtColor = pgItm[i].textRange.strokeColor;         if (pgItm[i].textRange.overprintStroke == true) {             if (stTxtColor.black == 100 && stTxtColor.cyan == 0 && stTxtColor.magenta == 0 && stTxtColor.yellow == 0) {                 continue;             } else {                 pgItm[i].selected = true;             }         }     } else {         var stColor = pgItm[i].strokeColor;         if (pgItm[i].strokeOverprint == true) {             if (stColor.black == 100 && stColor.cyan == 0 && stColor.magenta == 0 && stColor.yellow == 0) {                 continue;             } else {                 pgItm[i].selected = true;             }         }     } } removeOVPstroke(app.selection);  function removeOVPfill(sel) {     if (sel.length == 0) {         return;     }     c = confirm(＂删除填充叠印?＂, false, ＂Paint＂);     if (c == true) {         for (var i = 0; i < sel.length; i += 1) {             sel[i].fillOverprint = false;             try {                 sel[i].textRange.overprintFill = false;             } catch (e) {              }             sel[i].selected = false;         }     } }  function removeOVPstroke(sel) {     if (sel.length == 0) {         return;     }     c = confirm(＂删除描边叠印?＂, false, ＂Does not＂);     if (c == true) {         for (var i = 0; i < sel.length; i += 1) {             sel[i].strokeOverprint = false;             try {                 sel[i].textRange.overprintStroke = false;             } catch (e) {              }             sel[i].selected = false;         }     } }2.使用方式
