Re: [datacolor_group] Green blotches in print after creating new profile

>>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.

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 
measurement file> but I don't have an .xml file that I know of, is 
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 
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."

>>Yes, I did save my printed target sheets.

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

The above should assist further.
