Cone Color Profiles still print too red

4900

#1

We run three 4900 printers. Because of our work flow it is imperative that all three printers print identically. The largest percentage of paper run on the 4900’s is Epson glossy photo paper SO41271. Everything discussed in this thread has been run on that paper. Last fall, after running test prints from your supplied files and comparing those to your sample print created with your CC HDR inks, we decided to give Cone Color inks a try.

We started by converting over one printer. While information indicated that the inks were close enough that we could switch on the fly I did notice while running 100 prints of the same file and having switched out the blacks that there was a definite gain in red and loss of density. Nest step, get the full set of inks in and install the Cone Color profiles. Having done that we ran tests ofr your control image along with a 24 step gray scale. Using the CCP-4900-EPptoPaperGlossy profile and setting the media type to Ultra Premium Photo paper Luster, as outlined in your info, rendered a test print that is very red in the blacks compared to the same print on a 4900 running Epson Inks, and the Epson ICC profile and media settings for that paper. Interestingly a print on the Cone Color inks using the same Epson profile and Epson glossy paper media type renders a print that while still decidedly red is closer than the one created with the CCP-4900-EPptoPaperGlossy profile. While it is generally possible to correct for the reds, there are occasions when we just cannot reproduce a color as accurately as we can with the Epson inks. Until we get the CC inks printing to match the Epson inks I do not want to switch over my last machine.

It may be time for the custom profile, however the fact that we are farther off with your supplied CC profile than the standard Epson Profile makes me wonder if I am missing something.

Your desire for print to print match of neutral axis quality control requires a custom profile.

That said, you are using the wrong media type (Luster) where the profile (Glossy) was build for the glossy media type.

Still, I suggest a custom profile (for each of the three printers).

The luster is our default media type used for most ICCs. I believe this is an oversight in the instructions in that the [I]one[/I] photo black paper that needs to be run with a media type of Glossy is the actual Glossy paper. I will double check with the profile creator.

Just fyi on all of this, in a few months we will be coming out with a new Very glossy and Very black Photo Black. We’ll be re-profiling all x900 printers.

Walker, thanks for the fast response. I have a couple of follow up questions.

  1. We have been running 3 same model Epson printers for 12 years, and they have always printed pretty much identically using the same Epson profile, so why do I need a custom profile for each. Doesn’t it seem to follow that one custom profile would work on all three.
  2. If I have custom profiles created do I need to have them done again when you introduce the new Photo Black?

No, you won’t have to do them again when the new black is introduced.

It’s up to you on whether you want to do 1 or 3 profiles.

So what do you need from me to create the profile?
