If you were to make an image and take 100% ownership of its color management on your own computer. That is to say that if you originated the image and you used a color management system (an ICC you produced and a recommended workflow for it) and Epson inks/whatever media that you were with confidence able to repeat over and over as if second nature and produce identical prints with day after day - and then using the same exact system (computer, OS, software, printer, CM) but changed out the inks on your printer to ConeColor and produced a new ICC that took the ink changes into account - you should be able to repeat it with out any stress at all. You could go from Epson inks to Cone inks this way because you control what is happening on the same system and the same versions of OS, etc. This is a professional workflow. If and when something changes such as you buy a new paper batch that does not seem to match the ICC made for the older paper batch - you then just make a new ICC profile. But if you leave the printer sitting for three weeks and then make a print that no longer matches you DO NOT make an ICC. You freshen the inks in the printer by shaking the carts and performing an INITIAL INK CHARGE removing the variable of stale inks or pigment falling out of suspension from inside the printer, etc. This is all just basic stuff really that any Pro shop should practice and most do.
I do.
If you were originally using Epson media with Epson inks - you could use the Epson ICCs and Epson recommended workflow for both Epson and the change to ConeColor inks. If you were using a 3rd party media and supplied ICC - you should replace the ICCs with your own making using a reliable system such as Eye1 Publish on both the Epson inks and ConeColor inks.
I do that with all the papers I use.
But my understanding from you is that you are not necessarily using everything the same as the client supplied image/print including printer/OS/software - and possibly CM workflow. You have one or more variables in place from what I understand as well as printing from a program not known for its color management savvy (Aperture). <- That alone scares me….
I think you are misunderstanding the setup. They brought their Mac Mini in, printed right out of Aperture (I know it sucks) and we printed directly to my Epson 9900 with your inks via USB, just like they do to theirs at their office. So the only thing different is the inks, Epson in theirs, yours in mine. We did tests using Epson’s canned profiles and a custom profile I made. The sample print they brought in looked so different. They are using nothing but Epson’s canned profile at their office.
Forget Mac OSX as being standardized. It is not since 10.4.7. You can not produce ICC profiles on 10.6, 10.7, 10.8, or 10.9 that can be used on any other version without using something like QTR Print Tool to turn off color management (so that you can make an ICC profile.) This may or may not effect you meaning that you are using the exact same version of Mac OSX as the client is and both you and the client perform exactly the same steps from Aperture (should not be used for professional printing) to print the results you both get.
I use Adobe Print Utility when making my charts and basICColor to read and make the profiles.
In any event - you and the client should standardize to same exact version of Mac OSX, same exact version of Adobe Photoshop (Adobe CM works), same exact color management workflow including Adobe settings and Epson settings. Same exact ICC profile.
I know that, but again, we were using their computer, only variable was my printer vs their printer and of course they use Eposn’s canned profile, mine a custom one (I also tried using the canned one).
Then the variable is now only the 9900 printer each of you is using and/or the age and condition of the printer, and/or the age and condition of the inks inside the printer (a huge biggie). So you both insert fresh inks - perform an initial INK CHARGE - and now the only remaining variable is the printer condition and print head age (ability to make the smallest dot declines with age). It would probably require two custom ICCs to get these two systems as close as possible.
I agree with that. It appears both printers have the latest firmwares, but theirs is an original head, I am on my second one. My printer has printed thousands of prints, they the same (they print 50-100 copies of every image they print).
Now change your inks to ConeColor. Produce ICC. You should be good to go. This is a basic workflow.
I am confident my workflow is working well. I have been using your inks for some time now, done a shitload of prints with them. Have been very happy.
You have to control variables not just in the same exact workflow and use of ICCs but also OS and condition of the printer. You may not want to believe that something as benign as an OS version, or computer, or printer sitting in one location which you know nothing about, and your printer, etc should make a difference but they do and it can be significant.
I agree.
We can take a set of Epson inks and a set of ConeColor inks and make prints that are or are nearly identical in our studio. We do have a printer setup on Epson inks - I believe an R3000 or 3880 but we can match it to the 9900 running ConeColor inks. It’s not a rocket science to do so.WE do it regularly. But the condition of the inks and the printers and our taking 100% responsibility for the image and workflow (all computers in the studio are on same OS, etc…) All ICCs made with same system, etc.- this is all standardized including keeping an eye on humidity. We have to in order to be able to repeat.
I understand that you want this client’s work - but you have to be able to set them up correctly first in a way that will reliably mesh with your studio and the workflow you recommend and practice. Have you?
This is where it gets tricky. They are kind of secretive about their business. Not that its a CIA operation or anything, more of a cult. Yep, you heard right, a cult.
[B]So let me close with this new factor (as mentioned in the thread at some point). I recently acquired a very slightly used Epson 9900 with OEM inks in it. I invited that client back in with her Mac Mini setup, we connected to that printer and first test was EXTREMELY close.
So later I made some more tests on both printers (my setup, test image Dana sent me, Epson glossy, Epson canned profiles and my own custom made profiles; the two did not match. The Epson inks have a better “snap” to them, almost a better D-Max, not much, but just enough to make difference.
Just a few days ago another client came in with some 8x10 prints they had made on their Epson 4900 (maybe a 3880), OEM inks, Hahnemuhle Photo Rag. I made a test on my printer with your inks, a test on the 9900 with the Epson inks, same settings for both, both with custom profiles. The 9900 with the Epson inks matched perfect, the printer with your inks was dull.
So can it just be the printer, perhaps yes. I am not looking to blame anyone, just was trying to figure out what was happening. Now that I have the Epson with the OEM inks in it, and that client is 99% happy, I will just get back to making a living printing. I am going to keep both printers as is for awhile, kind of get a feel for why the difference, maybe the two will even out someday
