  • 1.  Fiery Profile Optimization on a Epson Sure Color P9570

    Posted 09-24-2024 01:57 PM

    I have been trying to get colorspace within tolerance on our Epson with no luck. This proofer is less than a year old and I cannot get the Max under a 5. It looks to be very dark greens that are causing the issue. Everything else is passing with flying colors. We never experienced this with our Epson Stylus Pro 9900. Any pointers would be appreciated.

    Hello Jesse Pena,

    Have you tried optimization option after making paper profile?

    In the optimization select maximum number of patches.

    If Optimization is not working try making a new epl & icc profile.

    I am sharing the screenshot of epl setting for your reference.

    Instrument could be different as per the availability.

    Try making a new epl & icc profile. After that start optimizing the profile with your reference profile (GRACoL 2006CoatedV2.ICC).

    It should work fine. Take care of below points also.

    •      Always use latest version of Proofing software.

    •      Use Automatic scanning instrument if possible.

    •      Clean measurement instrument glass & calibration tile with dry tissue paper.

    •      Check Nozzle of the Printer before calibration. If nozzles are clogged don't do calibration. First clean the nozzles.

    •      Make sure you are connecting measurement device with High Power USB cable & Port. Drivers should be installed properly for measurement device.

    •      While calibrating make sure you are scanning correct line or patch.

    •      Analyse measured data before making ICC profile.

    •      Your paper profile ICC gamut should be bigger than the reference profile.

    •      Optimize the profile if required.

    •     

         If you need further assistance, I would like to join you during the calibration of Epson Printer with Team viewer.

     The 9570 is a different Epson animal.  I found turning off Fast Rip on the EFI solves many issues. I suggest turning it off and starting over

    Have you tried a different green cartridge? I had a magenta out of tolerance last week.

    Couple of questions:

    What proofing paper are you using?

    Why are you using GRACoL 2006 as a target instead of the newer GRACoL 2013/CRPC-6?

    Are you using the correct M-condition specified for the data set? I think GRACoL 2006 should be M0 while GRACoL 2013 should be M1

    Other than that single max dE value, your other values look very good. Why worry about a single max dE value when everything else looks good? one "bad" dE on a single patch out of 1617 patches would not concern me in the least. Focus on possibly the "worst 10%".

    You could try Fiery's optimization routine to see if that snaps in that one bad value.

    Hello,

    Thank you for your insight. Everything you described I have already done or tried.

    The Fiery and the Epson have the latest software and firmware updates.

    I am using a new EFI ES6000 scanner to eliminate user error.

    I am using Epson Semi Matte Proofing Paper.

    I have done all of the head alignments and feed adjustments on the Epson.

    The Colorspace far exceeds that of GRACoL, but the calibration will not allow it to get under 5.

    I have tried creating a new Media Profile from scratch with the same issue.

    I believe there is an issue with the Epson P9570.

    I found there's a bug in Fiery XF, which only really rears its ugly head when trying to do Colorspace conformance - and it's always with the darkest colors. Fiery's FAST RIP functionality is the culprit here, I have no doubt. Turn that off in the Server Manager > System Info & Configuration > General Settings. You should probably recreate the optimization from scratch after turning FAST RIP off. Then it should pass with flying colors.

    From my experience with Fiery for the last year, it is a very buggy RIP. It comes to no surprise to me that the Fiery would be the culprit in this situation. I am going to try making a new profile with FAST RIP turned off and I will report back. I was also given some other tips to try if this doesn't work regarding the Epson Media settings on the printer.

    I'm with Terry on this. Having a one or a few patches over 5 dE is not abnormal or anything to worry about except as an abstract exercise. If your 95th percentile is within 5.0 dE00 you have official Colorspace compliance. If this is the result of a bug caused by FastRIP it is a very minor one. Dan, Terry, Craig, and I have been in this game long enough to remember when results such as yours would have been cause for celebration. Proofing has gotten so good since then that we've become spoiled. 

    But since the issue has been raised, understand that a color space conversion is a curve-fitting exercise, and some grid points, especially in darker colors, do sometimes "bulge" a bit in the attempt to preserve overall accuracy and smoothness. Measurement errors, nonuniformity in printing, and the algorithms used in calculating the output LUTs can produce some outlier dE values. So long as the overall accuracy and smoothness is good there is little to complain about. However, one is assuming high-quality proofing media, a properly working printer, adequate ink limits, etc.

    As a rule of thumb for Fiery XF, if the unoptimized proof gives an average dE above about 2.2, I usually reprofile before optimizing. This tends to reduce the max deviation.
