The Beauty of Stacked Strokes

Have you ever yearned to apply multiple strokes to on object in InDesign? Have you wanted more flexibility with your strokes than just a stroke and a gap color? For years now, I have wanted InDesign to be able to have the equivalent of the Illustrator’s Appearance panel, where I can apply multiple strokes and fills to a single object.

Why Do All My PDFs from Microsoft Office Print Fuzzy?

PDFs can "print fuzzy" when the black text is actually composed of all four colors of ink: Cyan, Magenta, Yellow and Black. This is a common problem from PDFs created from Microsoft Office documents. Before I send PDFs such as this to a commercial printer, I like to fix the blacks so that the document will print properly.

Let's take a look at a PDF with these incorrect blacks. In Acrobat, go to the Print Production pane > Output Preview.

I moused over the large black portion and the ink values are shown below. Notice how the black is actually composed of all four colors of ink.

When I turn off the black plate, the other three colors remain.

So how do we fix this? A quick search on google and even yields no quick results. I'm not a professional prepress technician, and I only need to convert the blacks in an PDF every once in awhile, so I tend to forget how, because I do it so infrequently. When I need to convert RGB blacks, I need to be able to do it without spending an hour or more searching on forums trying to figure it out. So for my own benefit, as well as any others who need to convert RGB PDFs from Office, here's the quick, super simplified explanation of how to do this.

1. Go to Print Production pane > Convert Colors.

That will bring up this dialog box. For our purposes, there are only two things to be concerned with in this dialog box. The first is the Conversion Profile. You can choose from a variety of CMYK conversion profiles, but SWOP is a good bet. And fortunately, it is the default here in the United States. Be sure to use a profile appropriate for your country.

The second thing to be concerned with (and this is the most important part), is the "Preserve Black" checkbox. According to the Adobe website, "Preserve Black preserves any black objects drawn in CMYK, RGB, or grayscale during conversion. This option prevents text in RGB black from being converted to rich black when converted to CMYK."

Click ok, and you are done. Now when you open the Output Preview dialog box and mouse over the back area, notice how the blacks are corrected.

And when you turn off the black plate, all the blacks disappear, as they should. Now the document will print properly.

I hope this tutorial will help you more quickly convert the RGB blacks in your Microsoft Office PDFs.
