Martin Bailey Photography: Workaround and Troubleshooting Print Profile Issues (Podcast 554)

As I mentioned last week, I found a workaround for an issue with my Canon PRO-4000 not correctly using the selected ICC profile when printing from Capture One Pro and I believe also Lightroom, so today I’m going to talk you through the issue and my workaround.

This really only applies to Mac users, and is also just a good way to troubleshoot ICC profile issues, so it could be useful for any Mac user that is having trouble getting good prints. If you are a Windows user, sit back and giggle at the fun and games us Mac users sometimes have to go through in our printing workflow.

To be totally honest, I’m a little bit uncomfortable putting this out there right now, because there are a number of unanswered questions, but I am traveling for a few weeks and I didn’t want to wait until I get back, partly because I want to potentially correct a statement that I made in my review of the Canon PRO-4000 large format printer.

Basically, I was seeing nasty crunched up gradations and transitions between a few colors in one of the photographs that I printed on matte fine art paper. What confuses matters is that the bright yellows in the image I printed are way out of gamut, so the printer shouldn’t really be able to print them anyway. But, my old imagePROGRAF iPF6350 used to print the same image pretty well, so it was a good test to compare these two printers.

During my tests, I tried printing with Capture One Pro initially, then to help me troubleshoot the issue I was seeing, I also tried Lightroom and I think also Photoshop, and I got the same results from each application. Since then, all of these products have been updated, and the Mac OS has been updated to Sierra too, so I’m not confident in saying that this issue is still occurring in all of these applications, although I did try from Lightroom again, and the print looked like it was still displaying this issue.

My main tests were with Capture One Pro though, as I printed some images out for last week’s review of the new media from Breathing Color, Signa Smooth 270. After a few prints that looked a bit iffy, I printed a black and white image that was supposed to be totally neutral, with no color toning, yet it came out of the printer with a strong brown cast.

Here’s a photograph of the brown print on the left, with the photograph that I printed after figuring out my workaround on the right (below). I actually quite like the toning of the brown print, but that was not intentional, so I set about finding out what was going wrong.

I’ve been printing photographs and working with fine art media for around 15 years now, so I recognize this kind of unexpected toning as a sign that the ICC profile that I specified for my paper and printer combination is not being correctly applied to my print. This sometimes happens after a major upgrade of the operating system, so I’m kind of suspecting Sierra, but my PRO-4000 review was created before that, so maybe things just got worse with Sierra. It’s hard to say without rolling things back and I don’t have time to do that right now.

Specifying Your ICC Profiles for Best Results

Anyway, if you print yourself, I hope you already know that the best way to get great color and neutral black and white prints is to create your own ICC profile for each type of paper that you print to. You have to do this on your own printer for best results. Failing that, you can often download an ICC profile for your printer from your paper manufacturer. If you print with a printer from a maker that also produces paper, you will sometimes find that the printer driver installation also installs a number of ICC profiles to your system as well.

Then, when you are ready to print, for best results, you will tell your software to not leave color management to the printer, and specify your own ICC profile. In this screenshot (below) from Capture One Pro, you simply need to select your ICC profile under the Color Profile pulldown on the Print screen. This generally works well even if you specify the manufacturer’s profile at this stage, and turn off color management via the printer drivers.

To check that you have turned off Color Management by the printer driver, you check that ColorSync is grayed out in the Color Matching screen before you send the print to the printer.

Test and Workaround

This is usually the way to get great prints, but during my recent tests, it just wasn’t working, so I tried a trick that I learned a few years ago, to test for problems with the use of the ICC profile during printing. Basically, you leave Color Management to the printer, which in Capture One Pro terms means selecting Managed by Printer under Color Profile on the Print screen (below).

Specify ICC Profile in Driver

Then, under the Color Matching screen in the printer driver, you will notice that ColorSync is not grayed out, and the pulldown below it is active. You then just need to select your ICC profile from that pulldown. If necessary, select “Other profiles” from the bottom of the pulldown, to see custom profiles that you’ve created or installed on your system.

Print and See

This is really all you have to do differently to either workaround the current issue that I’m seeing when printing to my PRO-4000, but as I say, this is a useful trick to remember as a way to troubleshoot profile issues in the software from which you are printing. This is how I was able to print my recent test images, and get a nice neutral black and white print of my Skogafoss Umbrella Man shot (below).

Of course, this is just a troubleshooting trick, and a workaround to try when for some reason your ICC profile is not being applied correctly when printing. The next step is to report the problem to either your printer manufacturer, and/or the company that makes the software from which you are printing. It may also be an Apple issue to fix, but generally the printer or imaging software manufacturer will work with Apple if necessary.

Correcting My PRO-4000 Review Statement

As I mentioned earlier, wondering if this was partly if not totally the cause of the issues I was having printing to matte media during my tests of the PRO-4000 when it first arrived, I also tried a quick print of my yellow poppies shot that was giving me trouble.

As you can see in this photo (below) the smaller print on the right has some very harsh transitions in the gradations around the balls of bokeh. The yellows in this photo are way out of gamut anyway, so I thought the PRO-4000 was just handling this worse than the iPF6350 did for some reason, but when I tried the print again using the workaround that I explained today, the print was much, much better, as you can see in the print on the left in this photo.

I was thinking that this issue was only affecting matte media, which was also strange, and to be honest, I’m still puzzled as to why everything looked great in my gloss test prints, but gloss paper has a much wider gamut than matte, so it was probably just able to get by without things looking out of wack, where as the smaller gamut of matte paper couldn’t hide the problem.

Check for Comments and Updates

As I also mentioned earlier, this issue is still somewhat up in the air. I don’t know yet which company needs to fix this, and I also haven’t got time right now to fully retest Lightroom and Photoshop in addition to Capture One Pro. I have confirmed that Canon’s Print Studio Pro does not have an issue, which kind of points to a problem when printing from third party imaging software, but I don’t want to speculate too much at this point.

The best thing I can recommend at this point is if you are here following a search to see what’s going on with your printer, check the comments below, or look for updates to this post, which I usually add as an [UPDATE: In square brackets], often in red if it’s a really important update.

So, a relatively quick episode today, but I wanted to get this out there, rather than sitting on this for a few more weeks as I travel. I hope you find this useful. If you learn anything about this or similar issues that you want to comment on, please do so below.

Also, before we finish, my next episode will probably be shortly before the New Year, if not January, so Happy Holidays!
