50 Unwanted Shades of Grey

Creating a neutral CMYK image in Photoshop

This is part of a series I will be writing about the process of making my photography book Fight Night, from stories about photographing events to the minutiae of trying to find a publisher, to the process of self-publishing. I hope you enjoy and learn a little something for your own personal projects.

I received my first copy of my Fight Night book from Blurb in the mail last week, and nearly every page had a distinctive color shift in the greyscale images. One page would be cool and blue, while the next page would have a distinctive pink cast. As excited as I was to hold a copy of my book that was ten years in the making, my heart sank at the inconsistent print quality. What follows is moderately nerdy on my part. You’ve been warned.

For those of you unfamiliar with what Blurb is, it is a platform that allows you to self-publish a book, then order as little as one copy at a time. The benefits of this are pretty obvious-no need to spend a massive amount of upfront money and fret about selling a giant inventory. Additionally, Blurb has paired with Amazon, so books can be ordered and sent to the customer automatically. It’s a pretty slick arrangement. There are some tradeoffs though. First, the per-unit cost is much higher is you are making one book at a time. Second, because Blurb is printing a wide variety of books at once, the quality of your particular book may suffer. But I had ordered books from there before and was reasonably pleased with the results.

Using just one-color black was never an option. The lack of ink density (I said I was going to get nerdy) would make the images look really weak. Because Blurb bulk prints multiple customers’ books at once, a spot channel black wasn’t an option either. So I used RGB to make sure there was sufficient ink density while keeping everything neutral. I converted the files to CMYK using the ICC profiles from the printer. When I got the proof book back, I quickly saw I was going to have to find another solution.

To make a long story short(er)I’m pretty sure I found a solution. I converted the RGB image to CMYK, and then remove the cyan, magenta and yellow from the highlight areas. Since the margin for error for a color shift is greater in the shadows, this should keep the image neutral. It also adds a bit more contrast to the images. I created an action and included it here. Enjoy.

The next step is to upload new files to the printer and wait for a new proof book. I’ll keep you updated.

With completion of classes I will get my diploma. And with that, clear the path for me to become an adjunct professor. :-)
