I use two wide carriage printers, HP 1050cPlus, 750cPlus.  Neither's colors matched my screen, I use photoshop cs6.  I calibrated my screen with a Huey Pro, and created a icc profile for the 1050 using a Spyder3.  I do a soft proof in ps and see some green blotches in shadows and other places.  I print on kirkland glossy paper (same as the test prints) and get the same green blotches.  Some of the skin tones are off too.  I'm printing two pages of test prints, a total of 240 patches.  I print using the printers color profile and it is actually better than using the icc I created with my Spyder 3.

Most of the photo came out good, just some colors were bad.  I read somewhere, that I might try printing new test prints but do 720 patches instead, or whatever the number is.

I searched the forum, many hits on "blotches."

I've had the same problem with other printers I have too, but want to concentrate on the designjet 1050 right now.

Okay, I'm going to assume from this that you calibrate your display(s) with a Huey (not ideal, but better than being uncalibrated). And that you use Spyder3Print (patch reader) or Spyder3PrintSR (strip reader) for profiling printer/ink/paper combinations. 

>>Most of the photo came out good, just some colors were bad. I read somewhere, that I might try printing new test prints but do 720 patches instead, or whatever the number is.

Increasing the effort and materials used before solving your problem is not a good idea. While your description (blotches) is new to me, and not very technical, if you are getting areas that are very off in color, that is most likely indicating errors in the patch or strip reading process. 

Open your existing measurement set and toggle between the "1" and "3" keys to see the values sent to the printer, then the values produced by the printer. Make sure the shift from the ideal to the real is even and consistent, and that the gradients are smooth, without any big, unexplained jumps. Reread any areas (you did save the printed target sheets, didn't you?) that are suspect, and build a new version of your profile. See if it prints differently than before. If so, there were errors in your patch reading previously. 

If that does not solve your issue, then it may be a color workflow error in the settings used. The best way to solve such issues is a support ticket at datacolor.com, not though forum discussions, but I thought I'd give it one shot, before sending you to the support system. They will want a copy of your measurement set (not just the profile), the details about your OS, printer, inks, and driver, as well as the settings used when printing targets, as well as prints, and a detailed description f your results, using the test image in the Print software, so gather as much of that up as possible before contacting them, to save time on both ends.

David:

Thanks for getting back on this.  I like to do as much research as I 
can before asking for help.  I went with the forums before filing a 
trouble ticket, as my problem is most likely my procedure.
Yes, the Huey Pro, that's what I have, better than nothing, didn't 
know better when I bought it.
My product is the Spyder3 print sr.  I'm running the ver 4.2.3 
s/w.  The type of monitor/s, video card, O/S, and other hardware/ s/w 
shouldn't matter here.
Not sure what you mean by "Increasing the effort and materials..." 
means but to solve a problem, best to keep the variables to a minimum.
I went to the printer settings and told it no color management, no 
color profile.  I then printed two pages of patches, 120 x 2 
(240).  I used glossy paper.
I created and saved an ICC profile.  BTW, while in the spyder 
program, I printed one of the sample photos, a young girl, kind of a 
pink blouse, blue jeans, white flowers, green palm leaves.  I those 
this photo because of the skin tones.  In my opinion, the photo came 
out perfect.
I then brought up photoshop cs6, went to the view/setup/custom, and 
chose my newly created profile.  Relative colormetric is set, all 
other boxes unchecked.  Funny, tried it just now and doesn't show the 
green blotches in the shadows.
Went to print, next print settings dialog box, manual color, color 
control, no color correction, that should turn off the printer's color control
At color management, told it that photoshop manages colors and chose 
my profile.
I noticed in the print settings, it shows "document profile sRGB 
IEC61966-2.1", whatever that means.
On the preview in photoshop, if "match print colors" is unchecked, 
photo looks normal, if I check the box, match print colors, I see the 
green blotches in the shadows.
With match print colors unchecked, I sent the image to the printer 
again, just finished, still with the green blotches in some of the shadows.

Trying to follow your instructions, I just brought the program up, 
where is my existing measurement set?  I can click on file>open 
measurement file>  but I don't have an .xml file that I know of, is 
that when you meant?  The name of the profile I created found in the 
Datacolor\SpyderPRINT\DATA\Print directory is "HP 1050 OEM Ink 
Kirland Glossy Paper.xml". is that what you want me to open.  I may 
seem compute illiterate, but I've worked with and on computers for 
much of my life, I'm 64 years old and have worked on computers since 
the '60's.  If you can give me more of a step by step procedure to 
show the values sent to the printer, I'd appreciate.

This is what I'm having an issue with:  "Open your existing 
measurement set and toggle between the "1" and "3" keys to see the 
values sent to the printer, then the values produced by the printer. 
Make sure the shift from the ideal to the real is even and

sheets, didn't you?) that are suspect, and build a new version of 
your profile. See if it prints differently than before. If so, there 
were errors in your patch reading previously."

Yes, I did save my printed target sheets.


I really appreciate your time and patients here, I'm getting close.

Would it help if I posted a scanned-in image showing the green blotches on the printed photo?  My gut feeling is that when I scanned in the patches, although there were no errors, perhaps some were not read right and in affect, made a bad look up table, so whatever color it meant to print, printed green.  I know there is a way to look at the data file but there has to be a simple explanation. -  Jim

>>Thanks for getting back on this. I like to do as much research as I

trouble ticket, as my problem is most likely my procedure.
Yes, the Huey Pro, that's what I have, better than nothing, didn't 
know better when I bought it.
My product is the Spyder3 print sr. I'm running the ver 4.2.3 
s/w. The type of monitor/s, video card, O/S, and other hardware/ s/w 
shouldn't matter here.

OS and OS version matter, in that things aren't quite the same between Mac and Windows or between different versions of OSes... Especially between the last few versions of OS X... And the driver I refer to is your printer driver version, which does can indeed effect results. 

>>Not sure what you mean by "Increasing the effort and materials..." 

Printing lots of high patch targets in frustration ends up costing some users a lot of time and materials. I'm suggesting minimizing all of that until you can determine the problem. 

>>means but to solve a problem, best to keep the variables to a minimum.
I went to the printer settings and told it no color management, no 
color profile. I then printed two pages of patches, 120 x 2 
(240). 

That's correct, at least on the surface; with some combinations of recent OS X versions, and printer drivers, it may be more complicated than that. 

>>I used glossy paper.
I created and saved an ICC profile. BTW, while in the spyder 
program, I printed one of the sample photos, a young girl, kind of a 
pink blouse, blue jeans, white flowers, green palm leaves. I those 
this photo because of the skin tones. In my opinion, the photo came 
out perfect.

That would indicate that your profile is good; and that any problems you are having are beyond profile creation, in profile application. This, technically, is not a Datacolor issue, but we do want to assist people in printing with profiles, since it won't do them much good to build them if they can't. 

>>I then brought up photoshop cs6, went to the view/setup/custom, and 
chose my newly created profile. Relative colormetric is set, all 
other boxes unchecked. Funny, tried it just now and doesn't show the 
green blotches in the shadows.

ICC profiles are consistent; right or wrong, they produce the same results. If you are seeing something different, that implies user variation...

>>Went to print, next print settings dialog box, manual color, color 
control, no color correction, that should turn off the printer's color control

It should, and under Windows, and older Mac OSes it does. Under newer Mac OSes, it usually does, but not in all cases...

>>At color management, told it that photoshop manages colors and chose 
my profile.
I noticed in the print settings, it shows "document profile sRGB 
IEC61966-2.1", whatever that means.

Again, you have not included the necessary facts, as you did not see how they could be relevant, so I can't accurately address your case. But under Lion and Mountain Lion, this setting should (hopefully) avoid Apple causing an unintended conversion. For Snow Leopard, GenericRGB would be the right choice to avoid an undesired conversion. 

>>On the preview in photoshop, if "match print colors" is unchecked, 
photo looks normal, if I check the box, match print colors, I see the 
green blotches in the shadows.
With match print colors unchecked, 

Checking this does not effect your prints, just your preview. The fact that Photoshop's preview shows blotches, but SpyderProof does not is curuious, but I suspect that you are not printing the Datacolor Matrux test image, so the comparison is apples-to-oranges...

>>I sent the image to the printer 
again, just finished, still with the green blotches in some of the shadows.

Trying to follow your instructions, I just brought the program up, 
where is my existing measurement set? I can click on file>open

that when you meant?

There is a fork in the app, which lets you coring and measure a target, or choose an existing measurement set. From there you can choose the set by name.

 >>The name of the profile I created found in the 
Datacolor\SpyderPRINT\DATA\Print directory is "HP 1050 OEM Ink 
Kirland Glossy Paper.xml". is that what you want me to open.

Yes, that's the measurement set, but don't pry it open in an XML reader, navigate to it in SpyderPrint, and open it there to check it, and possibly remeasure some patches. 

 I may 
seem compute illiterate, but I've worked with and on computers for 
much of my life, I'm 64 years old and have worked on computers since 
the '60's. If you can give me more of a step by step procedure to 
show the values sent to the printer, I'd appreciate.

It will all be apparent, visually, and by the numbers, once you navigate the "Open Existing Measurement Set" branch of the application.

>>This is what I'm having an issue with: "Open your existing 
measurement set and toggle between the "1" and "3" keys to see the

The above should assist further.

It would be best to check the measurements, or retread the entire set of targets taking care that you are reading correctly. That's likely to be the issue. See previous post for how to do that.

CD Tobie:

Looks like we solved the problem.  I did not print a new set of targets but decided to scan them again.  When there is an error, the system usually flags it and I'll re-scan it.  What I've done in the past if there is an error on a row, I'd click on say A1, and scan the whole row.  I'd do this until I see no more errors.  Apparently that was where I was wrong.

This time, I toggled between 1 and 3 and found several patches with a huge difference in color, kind of like one that should be black came up white.  There were a few others way off too.  I didn't scan the entire row, but clicked on that patch with the mouse, and just scanned that particular patch.  I then saved the profile, went back to photoshop and printed.

Bingo, a perfect photo, at least to me it's perfect.  I had no idea I was getting bad scans, now I know how to check.

BTW, as many computers as I own, this is my favorite, running windoze xp prof.  My only experience on macs was when I had to repair them for customers, didn't really like working with them, but I never argue with people, the customer is always right.  Other systems I use, two with win7 and one linux box.

I'm going to call it a night, later I'll try some different paper and make some more profiles.

Thanks for all your help, you steered me into the right direction -

Jim

Yes, the artificial intelligence is helpful, but it doesn't entirely replace caution in scanning, and careful checking of the results, as it can't detect all possible errors, only the more extreme ones. Glad you now have a sense of the process. I predict it will continue to improve with practice, and that you'll have good luck with your profiling as you move forward.
