Hi I had a profile done for my paper and printer, printing from my Mac G4 and it produced great results. I have now got a MacBook pro and copied the profile across to the relevent folder and tried printing from PhotoShop from the laptop. The result is hopeless and not like the excellent prints I get from my G4. Do I have to have new profile done for the MacBook even though I am using the same printer and paper to get good results? It would seem so.
Jules

Jules,
No, you should not need a new profile. If the print settings are identical on both computers printing the same file with the same output profile to the same printer, then the results should be identical. You might try this: Convert the image to the printer profile in question (Edit>Convert to Profile), save it as a test file, and print that file from PS using Print With Preview with "Color Handling" set to "No Color Management and all color management turned off in the printer driver. Print the same converted file with identical settings from each computer and they should match.

Good Luck,
Ed

I will try that but are you sure, I have been advised that the new machine will most probably use a different colour conversion engine to the old hardware. Could this be so. Remember that the Intel based machine is very different from the old G4.
Jules

Jules,

Yes - I am as sure. If you are printing from Photoshop, you should be using the same color management module (CMM) and the differences that you describe are not processor related.

Ed

I have tried. The print from my G4 is superb and the one driven from the MacBook, using exactly the same profile and settings is washed out. Have you actually tried what I am doing with one of the new dual processor, Intel based MackBook Pros? I don't disbelieve you but practice seems to prove something different.
Jules

Jules,
Are you running Mac OS X on both your G4 and MacBook? The processor won't influence your printing results but I remember having seen issues involving Epson printer, profiles generated on a Mac running Mac OS 9 and printing on Mac OS X.

FWIW, I print from different Macs (G3, G4, G5, Intel), all running Mac OS X and all are using the same printer profiles.

Jules,
Yes - I have used the same print profile across the board and yes, if you tried EXACTLY what I suggested in my first post and still achieve different results, then the problem is a difference between user settings -OR- internal software system settings that you may not be aware of. I am delighted to help, but unless you follow exactly what I suggest, and report back fully, I cannot help you.

Best Regards,
Ed

Yes OSX on both.
Jules

OK Ed, can you tell me how I check whether I am using the same color management module (CMM) on both as I do not know how to do this. Thanks in advance.
Jules

Jules,
In photoshop, Edit>Color Settings third panel down "Conversion Options" - "Engine".
However, did you try making the conversion manually as I described in my first post on this subject, and printing the identical file on both computers from Photoshop?

Ed

Hi Ed, sorry for the delay, I was away. They both have .....Adobe (ACE) and below that .....relative. is that any help?
As for ....'making the conversions@, whta conversions? have i converted something. I thought one just loaded a profile and chose it when printing. sorry for my ignorance but i have always wanted to get to the bottom of this complicated (in my opinion) setting(s).
Jules

This sounds exactly like the problem I am having with my Core2 MacBook Pro, but applied to a different scenario. I simply cannot get consistent colour when outputting to the web - it is correct in unmanaged applications, but as soon as colour management kicks in, the colours are wrong.

I actually suspect that something to do with ColorSync is broken on Intel macs, as I have tried everything I can think of to try and get it sorted, and as far as I can see, I haven't made any mistakes creating/setting up profiles etc.

It seems less and less likely that you've actually followed any of the advice you've been given thus far with every post you make. Do everything this article says without deviation on both machines before you do anything else:

If you aren't following that procedure with every print you make, then your complaint simply is not valid.

Jules,
Orangekay made reference to a good article by Chris Murphy which may be of some help.

Based on more years of expeience that I want to publicly admit, I was attempting to help you solve your problem, knowing that - at least for me - is not related to the intel processor. In my first post on this subject, I gave you rather detailed instructions - if you need more help with that, just let me know. Based upon the results of that "test", we could start to pinpoint the problem and go to the next level. So, if you will do as I suggested, record all settings and report back, perhaps we can resolve this.
BTW - what printer are you using?

Regards,
Ed
