Following some discussion with Canon regarding an issue with printing on my PRO-4000 printer from Mac OS X Sierra, I’ve confirmed the effectiveness of one workaround and one technique to overcome the issue, and I’m going to share these with you today.

[smart_track_player url=”https://www.podtrac.com/pts/redirect.mp3?https://traffic.libsyn.com/mbppodcast/mbpp_ep573″ src=”https://app.fusebox.fm/embed/player.js” class=”mbp-ignore”>

To give you a little bit of background on this issue, I bought the Canon imagePROGRAF PRO-4000 44 inch large format printer, which I reviewed in the summer of 2016, and although I absolutely love this printer, I found that there was an issue after upgrading to Mac OS X Sierra, and I essentially found myself double profiling.

Double profiling is when the ICC profiles that we usually apply to ensure accurate color reproduction, for some reason gets applied twice, and that generally messes up the colors. The problem is more apparent when printing to matte media, probably because the ICC profile is doing more work with matte media than it needs to do with gloss, and that in turn gets amplified more when you double profile. Black and white images suffer a nasty color cast regardless of the finish of the media.

In December 2016 I reported that I was having problems, and provided a workaround, which I’ve been using since. I’m not going to go into detail today, as you can see that workaround and troubleshooting technique in Episode 554. I had spoken to some of the guys on the large format printer team at Canon in March this year, when I was there to view the test prints that they’d created in February for the CP+ show in Yokohama.

I was told at the time that there may be an issue that Canon are aware of, and that a driver update was imminent, but I didn’t hear anything for a couple of months, so I followed up with them last week, and they suggested that I try a couple of things. I’ll go into detail on these shortly, but to cut a long story short, both techniques worked, so I’m happy to be printing easily again, although with a different workflow than I’m used to using.

Double Profiling Examples

Before we get to the workarounds, let’s look at a some photos of my test prints, so that you can understand how the double profiling effects the prints. I made a test image of four images in a row, which I printed at 24 inches wide and 10 inches high. In this photo (below) you can see three vertical strips of four prints.

The left and center vertical columns of images were printed using the two techniques that I’m going to explain, and the right column of images was printed the way I’ve been printing for more than 15 years, and will hopefully at some point be able to work with again. Although the left column might look a little bit darker, this is because of how I photographed the images. The prints using both techniques are actually identical.

As you can see, the right column color images are less vivid than the center and left column images, and the black and white image has a strong sepia tone, although the base image is totally neutral, like the center and left images. Another very unwelcome symptom of this double profiling, is a very nasty blotchiness in the blue sky, as you can see in this closer photograph (below).

If you can’t see the detail, click on the images to open them at their full size, and widen your browser window if necessary. To stop the images from auto-advancing, just roll your mouse over them. You should be able to see how nasty that sky turned out, yet the original image has a very smooth blue sky.

The photo has a much cleaner clear blue sky in the center image, as you can see in this image (below). We can also see that some of the red color has gone from the mountains, and the red from the top of my Namibia photo is also much weaker.

As we can see in this last photograph of the test prints (below) the black and white image gets a strong sepia tone. I actually don’t dislike this artistically, but when it’s not supposed to be there, it’s a problem.

Only Effects Custom Media Types

One other thing that I should mention, although I have not tested this myself, is that this double profiling issue only effects custom media types. If you use Canon brand media with their ICC profiles, I’m told that there are no issues. If you have found otherwise, do let me know. I can do more tests, but for now, I’m trusting what Canon have told me.

As this started to happen from Sierra, I think it’s safe to assume that if you are using Windows, you don’t need to worry about this issue either.

Workaround – Disable Print Preview

OK, so now you can appreciate the problem, let’s look at the two ways to avoid this. The easiest way, although somewhat risky, is to simply turn off the Preview when printing, as you can see in this screenshot (below).

I usually use the preview as a final check before hitting the print button, so this worries me, but it works. The center of the three strips of images was printed this way, and the colors are printed as expected.

Embed ICC Profiles in Custom Media Settings

The second thing that I have confirmed to work, is to embed the custom ICC profile into the custom media that I created on the printer, to print to my favorite Breathing Color media. To do this, you first need to open the Canon Media Configuration Tool that you will have installed with your printer drivers etc.

I actually recommend that you create new custom media and embed the ICC profile into that, rather than simply adding it to your current custom media, because I’ve found no way to remove an ICC profile once you add it. If you save the information without a profile specified, it just leaves the one you previously added, and there is no option to delete the profile.

I first tried to simply reimport the media information from the media information file that I saved when I first created the custom media on the printer, but that failed because the original media was still there, rather than allowing me to duplicate it, so I had to create each media type again from scratch. In this screenshot you can see that I have recreated most of my custom media types with the letters ICC appended. These are the media types that I’ve embedded my ICC profiles into (below).

Once you’ve created a custom media type, to embed your ICC profile, select the media type in the Media Configuration Tool, and press the Edit Custom Paper button, then click the ICC Profile tab, and browse to your ICC profile. This could be one you created yourself, or one that you downloaded from a third party paper manufacturer.

I found that the Media Configuration Tool doesn’t recognize ICC profiles on the Mac OS that don’t have an extension. The .icc extension isn’t necessary on a Mac, so I generally save my ICC profiles without an extension because it looks cleaner. But, MCT doesn’t recognize the file as an ICC profile without the .icc extension.

Also, if you use long descriptive file names for your ICC profiles, as I do, these also cannot be used. For most of my profiles, I had to shorten something like  “MBP Canon PRO-4000 Breathing Color Pura Smooth” to “MBP Canon PRO-4000 BC Pura Smooth” before I could embed the profile into the media information on the printer.

Update Media Information

Once you have embedded the ICC profile in the media, ensure that you go to the printer drivers in the System Preferences, click the Options & Supplies button for your printer, then select the Utility tab, and click the Open Printer Utility button. From the Printer Utility dialog, select Media Information, and click on the button to update it. This brings the information that you added to the printer back to the computer.

It would be nice if this happened automatically, especially as I added the ICC profiles from the same computer. I actually missed this for a few days, as it didn’t work like this on my old Canon large format printer, and I spent a lot of extra time over the weekend trying to figure out what was happening.

The Printing Workflow

So, once you have your ICC profile embedded in your media information, you can print how I’m sure most of you are used to printing. To be thorough though, I’ll quickly run through the important points about that process.

Once you have the image that you want to print ready, you’ll select Print and then it’s important to select that the program you are printing from manages colors or color correction. In Photoshop, you’ll select Photoshop Manages Color under Color Handling, and then select your ICC profile from the Printer Profile pulldown.

I do all of my printing from Capture One Pro now, so all I have to do is select my profile from the Color Profile pulldown, and Capture One then knows that it’s in control of color, rather than leaving it to the printer driver software.

Then, after ensuring that my margins are all as I want them, I hit the Print button in the bottom right, and check two important settings. The first is on the left in this stitched screenshot (below). Under the Color Matching tab, ensure that ColorSync is selected, but greyed-out, essentially showing that the Mac OS is not doing any color management.

On the Quality & Media tab (above) we also need to ensure that we select the Media Type that we created earlier with the ICC profile embedded. We also of course need to ensure that the printer has that Media Type selected. Then, the whole point of this, is that I can now turn on the Print Preview, to get my final confirmation that all looks good before I send the print to the printer.

Print Preview

Although I could live without the Print Preview if I was forced to use the first workaround that I mentioned today, I have to admit, I do like to see this preview screen (below) and get final confirmation that the print looks how I expect it to before I press that Print button.

Recap of the Issue

Just to reiterate, at this point in time, May of 2017, if you don’t embed the ICC profile in the media information for custom media, and you use this Print Preview, when you print the image, the colors will all come out weird. It’s a bit of work to set up the printer to use media types with ICC profiles embedded, especially if you use more than a few different media types, but to me, it’s worth it to enable this Print Preview.

I also heard from Canon that they would actually prefer people to embed the ICC profile into the media information on the printer, so now that I’ve gotten used to this idea, I will consider continuing to do this even after the underlying problem is fixed, if it actually can be fixed. Canon at this point don’t seem too confident that there is anything they can do, so if you want to upgrade to Sierra, and you use custom media types, this may well be the only way you can do that.

I should also mention that I am assuming that people using the PRO-2000 will also probably run into this issue, as well as PRO-4000 users, but I’m not sure about the other new imagePROGRAF PRO printers like the PRO-1000 or the 8 color 6000S and 4000S.

Other Minor Issues

Before we move on, I wanted to briefly mention another issue, which is that when I initially tried to add the ICC profiles to the media information on the printer over Wifi, and more importantly, with my PRO-4000 connected to my network via an Apple Express base station, I was not able to export the updated or new media information to a file, or edit it in any way. The only thing I could do was delete it, and that’s not very useful.

Then, I tried with a wired network and all was good, so I went back to my Wifi and found that if I set up my PRO-4000 to connect directly to my Apple AirPort Extreme base station instead of an AirPort Express, I can add the ICC profiles to the media information and save this to a file, and edit the details of the media in the Media Configuration Tool, so I’m leaving my PRO-4000 set up that way for Wifi. If you find you have trouble editing the media information over Wifi, this could be the cause.

And, if you are wondering why I would even be using a large format printer over Wifi in the first place, I only really do this for management tasks and small prints. When I want to do larger prints, I actually run a long LAN cable from the printer on my second floor, to my studio in the third floor, or I print from my MacBook Pro on the second floor, using the USB connection directly to the printer.

Printing Patch Sheets for Calibration

There are also a couple of last relatively important things that I’d like to point out, the first of which is that when you get a new type of media, if you create your own ICC profiles, you will initially set up the media in the Canon Media Configuration Tool without an ICC profile, because you haven’t created it yet. This is good, because we don’t want any profiles coming into play as we print our profiling patch sheets. You can then add the ICC profile to the media type after you’ve created your patch sheets and then the profiles.

If for any reason you need to create a new profile, you will have to use a media type without an ICC profile embedded, because we have to turn off all color management when printing our patch sheets. This is another reason that I decided to create a new media type to embed the ICC profile to, and not just update my original media types.

Use Print Studio Pro for Patch Sheet Printing

While we’re talking about printing patch sheets, I want to also mention that I’m now using Canon’s Print Studio Pro to print my patch sheets, as I’m told it has a pretty reliable way to completely turn off all color correction, and this is an important part of this process.

For a number of years now, I’ve been using the Adobe Color Printer Utility, but people have reported mixed results with that for these imagePROGRAF PRO series printers, so I tried using Print Studio Pro and the resulting ICC profiles are different, so that indicates that one of these programs is doing something different, so for now, I’m trusting my friends at Canon on this.

Actually, before we finish, I should also mention that I am using the X-Rite i1 Photo Pro 2 Color Management kit to create my ICC profiles. This might be overkill if you are not using a large format printer, in which case the ColorMunki Photo is a great alternative solution, but for this level of printer, or for the totally quality conscious among you, the i1 Pro 2 is the best available solution if you want to create your own ICC profiles for printing.

I realize that this episode won’t be of interest to many of you, so sorry if you don’t print or use a Mac, but if you have listened or read this far anyway, thanks for sticking with me, and I hope you were still able to gain a few takeaways from this.

Thanks to Canon

Finally, I’d like to thank Canon, not only for their patience as we worked through these issues, but for creating this amazing line of printers in the first place. As I’ve printed more with the PRO-4000, I’ve realized that they really have created something special. Gloss media blew me away from the start, but I was initially not happy with the performance of printing on matte media. However, since we’ve figured out these issues, and now arriving at a very workable solution, the results I’m getting with this printer are absolutely stunning.
