Re: how to disable color management of the pixma pro 100 under mac ios Sierra

Hi SpiceWeasel76..

 

1. see my response I just posted on the ICC Profile thread.

 

2. why are you selecting varios profiles - are you changing the paper type?

 

3. ProPhotoRGB is not a profile for printing.

 

4. What paper are you trying to print on?

 

5. Just for a problem check, print a Nozzle Check and see what the results are.

Hi John,

 

Thanks for responding so proptly, and for pitching in to help. 

 

  1. Yes, I had printed the test image out and it was pretty darn good (albeit on 4x6"), nothing seriously concering there when using the guide to evaluate. 
  2. I am trying different paper profile types because I am using Kodak 4x6" paper (which I got at a good price from the local office supplies chain store) and that's what I had been using prevously. As there are no ICC profiles for this I was trying to find which one was closest. 
  3. I realise that PhotoPro wasn't a printing profile but, having tried all those, I thought "let's see what a screen profile does, in case I get lucky and it kinda matches". Interesting, but no. 
  4. As above it's Kodak, specifically " Kodak Premium Photo Paper : Gloss 240 GSM, 4x6"
  5. Performed a nozzle check - just for the sake of thoroughness. 95% fine. LGY (I had just changed for a non canon cartridge) needed a clean (which then make GY worse) but otherwise no real issues. Nothing that would immediately correlate with my problem.
  6. I used to just print (using the AirPrint driver I now realise) from Apple Aperture, and I did over 100 prints and they were fine (not amazing, sure - but fine). I was forced to change to Adobe Lightroom and on top of all that (with my 87+ thousand pictures to reorganise) deal with this whole new world of ICC profiles I just can't seem to print a reasonable looking photo. 

I hope your wisdom with this stuff can be of help because (despite being a former Film camera professional - even back in the pre-digital  days - with higher than average computer literacy) this printer stuff is absolutely "doing my head in". 

 

I'm seriously starting to regret not just taking my prints to the local place to have them printed at 10c a pop instead spending AUD$685 on a printer and hundreds more on ink and paper just for this kind of hassle.. I'm not seeing the benefit right now!

I'm torn between selling the **bleep** thing vs my pride refusing to let me be beaten by a **bleep** printer. lol

 

Fingers crossed.

Hi SW.

 

Some ithoughts:

 

1. Until you get good nozzle checks I think you will be chasing problems. It sounds like you are having problems in that area.

 

2. I use OEM inks, so I have no experience with third party inks, but I do follow a great resource on the web - a YouTube channel on printing operated by "jtoolman". He is a strong advocate for a particular brand of third party inks, but does stress the need for custom profiles.

 

3. You have several variables you are dealing with. Even with a well functioning printer and Canon inks you would need to hunt for a profile that was best for your paper. Even with Canon inks and Canon papers I have seen poor results when the incorrect Canon profile is selected.

 

4. Color management is automatically turned off when using Lightroom (or PS) on a Mac. You will see the color choices grayed out in the driver.

5. You said the test print is coming out OK. How does it compare with the on-screen image?

 

I do my own printing because I consider it finishing my images. I agree that for small prints and multiple copies for family/friends.

Re: how to disable color management of the pixma pro 100 under mac ios Sierra

Hey John,

 

  1. Nozzle checks done and cleaning performed. That is resolved, but has no efect on my issue.
  2. I'm not convinced the inks have anything to do with it. I had this issue before and after chainging inks. Most of the inks are Canon original, and when it started they all were, then one not, now two.. No change to the problem so I think it's highly unlikely to be the bran dof ink.
  3. I cannot find a profile for my paper that is even remotely close - this is not a subtle thing we're dealing with here. A slightly tanned skin tone comes out looking like horrendous sunburn. It's very strong.
  4. I can make that option greyed out or not greyed out depending on whether I let printer manage colour or software.. I've tried various options, and haven't yet found anyhing satisfactory.
  5. The test print was pretty fine - matched the onscreen image pretty well. It was 4x6" not A4 but close inspecion revealed no issue.. to be honest though that was so many changed variables ago I can't recall anymore what settings I was running at that moment. 

It seems the variable is the profiles mainly.. the other things are much less important and dont account for the variation I'm seeing - certaily not to the degree I am seeing it.

I heard some suggestion somewhere that the magenta cast can potentially be from a profile applying twice? I'm not sure hwow that would happen of that is indeed the case.. but i'm fairly confident the issues I'm haivng can be laid at the feet of the colour profile presets.

I might go back to the AirPrint driver and see if I can get back to where I started. 

I'll let you know how that goes, but I am very open to any insight you may be able to offer, because it feels like it really shouldnt be this hard.

 

Thanks again

Good. A This tells us the printer is outputing correctly.

Ink can affect the output, but it is generally more subtle than the effect you seem to be reporting.

 

  1. I cannot find a profile for my paper that is even remotely close - this is not a subtle thing we're dealing with here. A slightly tanned skin tone comes out looking like horrendous sunburn. It's very strong.

Lets cover this later.

 

  1. I can make that option greyed out or not greyed out depending on whether I let printer manage colour or software.. I've tried various options, and haven't yet found anyhing satisfactory.

If you select Ps (or any other software) to manage colr then the Canon/MacOS driver will sitch off color manabement in the driver (as you are seeing). If you select Printer Manages Colors then when you go to the driver you see two choices - ColorSync and Canon Color Matching. You can select either one. If you select ColorSync then you also have the option to select a profile - Automatic or one of the profiles that are installed in the computer. If you select Canon Color Matching there is no option to select a profile. The other part of the printer setting that is needed to be chosen is the media type under Quality & Media. This is your paper type.

 

Simply put, there are two general types - glossy and matte. More accurately, there are differences in surfaces and Canon has various media types - Luster, SemiGloss, Matte Photo, Other Fine  Art etc.

 

When you select Canon Color Matching and choose a Canon paper type the Canon ICC profile is automatically chosen. A similar thing happens if you select ColorSync and select Automatic in the dropdown.

 

The media type selection controls how ink is applied to the paper. Different paper surfaces need different applications and a Canon printer only understands Canon papers. That is why when you purchase third party papers they will/should include in the package guidance on what media type to select for various printers.

 

I am assuming that your Kodak paper is probably a glossy surface, so you should be selecting one of the glossy paper types - a good choice would be Other Glossy Paper. What happens to your print if you select Canon Color Matching and Other Glossy Paper?

 

  1. The test print was pretty fine - matched the onscreen image pretty well. It was 4x6" not A4 but close inspecion revealed no issue.. to be honest though that was so many changed variables ago I can't recall anymore what settings I was running at that moment. 

There are several steps in the color management process. You have the color of the image as it is captured in the digital data of the file. There is how the monitor displays that digital data and finally how the printer prints that digital data. There is no connection between what you see on the monitor and what the printer prints. That is the purpose of the test image and why the instructions say not to make any adkjustments, just open the file and print it. The test image should be printed using your chosen printing settings - media type (and ICC profile if you are using one). If the test image comes out OK then there is nothing wrong with the printing process. Conversely, if the test image looks off the problem needs to be identified and corrected.

 

Then, once you have a good test image you compare to the display and get them close. From that point on you should have print output that is close to what you see on the display.

 

It seems the variable is the profiles mainly.. the other things are much less important and dont account for the variation I'm seeing - certaily not to the degree I am seeing it.

I heard some suggestion somewhere that the magenta cast can potentially be from a profile applying twice? I'm not sure hwow that would happen of that is indeed the case.. but i'm fairly confident the issues I'm haivng can be laid at the feet of the colour profile presets.

I'll let you know how that goes, but I am very open to any insight you may be able to offer, because it feels like it really shouldnt be this hard.

 

My recommendations are:

 

1. be sure you have a good nozzle check - looks like you are there

2. select Printer Manages Color in Ps

3. select Canon Color Matching in the printer driver

4. choose a media type in Quality & Media that is close to your paper surface

5. print the test image

 

If you have some Canon paper that would be really good to use for the above. It would eliminate all variables except the printer itself.

Hi John,

 

So after coming back to this and trying your suggestions, as well as swapping printer drivers - I was getting the same ridiculous overblown skin tones no matter what printer driver or colour settings I was using.

 

I decided to test the printer again and this time my nozzle check shows that GY and LGY are not printing at all. 

Not some minor broken lines on the test print as before.. just blank. 

 

So I suppose my non-canon replacement inks are failing. ...sigh. 

Doesn't help with the previous magenta issues.. but since that is where I am right now.. I suppose will have to decide to either a) re-purchase canon inks (at exorbitant prices) or

b) sell the printer and get on with my life.
