: My Screenshoots are "too light" for printing (Completely rewritten version.) I'm a writer doing a book for an overseas publisher. My deliverables for them are .doc files for the text and .png

If it's not high quality printing, text in a gray color can become very hard to read. To create gray, they have to screen back black into a halftone, and on coarser line screens, that can turn out hard to read.

So maybe that is their concern. I don't know. I'd definitely ask them what they specifically mean by 'too light'.

As for making them darker, I don't really see why you should have to do that. But if you must, I'd consider using the LEVELS or CURVES tools in your photo editing app to see if you can boost the grays to be a bit darker.

Another option might work depending on your images is to place the image into your photo editing app, duplicate the layer, and set the top layer to 'MULTIPLY'. Here's an example of the result of that technique:



If you start seeing weird artifacts like you are doing, that typically means you're working with a JPG image. You definitely don't want to edit the JPG. Make sure your screen shot software is capturing in a better format for this such as PNG.

So it might be true that it can't be printed due to little color application. But that is a print production issue, your publisher might just be speaking out of experience, warning you.

You can check for yourself in Acrobat Pro in the Output Preview to get an idea.



Based on that you can correct your screens and re-test them in Acrobat.
