Hi Andrew,

I think they mean "pleasing color" accuracy to sRGB. :-)

that is what I understand ;-(

Can someone explain what Apple is trying to tell it's customer with respect to display calibraiton here? ---- http://www.apple.com/imac/design/ Individually calibrated for true-to-life color. None of these innovations would matter much if the iMac display didn’t deliver vivid, true-to-life color. Which is why we put every display through an exacting color-calibration process using state-of-the-art spectroradiometers. This equipment is tuned to meet color standards recognized around the world for precision and accuracy. ---- Aside from the marketing hype starting with calibrated for true-to-life color, what are they calibrating for, and what color standards recognized around the world for precision and accuracy are they talking about?

Sorry, I worded it not the way I meant. Using i1Publish and an i1Pro hardware, can the iMac be profiled to be close to an NEC PA272w? What can be done with the current MacBoo Pro’s with their Retina display? David

In it's dreams! Aside from the difference in gamut, there's a lot of capability in the NEC that Apple can't even touch.

1. Nearly all if not all current SpectraView displays are wide gamut, Apple's are not (sRGB like gamut). 2. SpectraView uses a high bit internal processing path (at least 10-bit) with internal 3D LUTs, Apple and many other's do not. These high bit LUTs allow precise adjustments to be made to the display’s Tone Response Curve without reducing the number of displayable colors or introducing color banding artifacts. 3. Newer NEC SpectraView's use GBr LED which produce far more precise control of White Point, run cooler, use less energy, run far longer than CCFL. 4. SpectraView has 3-4 year on site warranty, Apple has 1 year. 5. SpectraView panels are hand selected from the manufacturer line (pick of the litter). 6. SpectraView has electric technologies like ColorComp, which adjusts and improves screen (brightness) uniformity using individually measured matrices for each display at the factory. All done high bit with compensation for operating time and temperature. Apple does not. 7. SpectraView has electric technologies like GammaComp, to adjust the monitor's internal 10-bit gamma Look-Up-Table, allowing various custom display gamma or Tone-Response-Curves to be achieved. Apple and many other's don't have anything like this. 8. SpectraView is a smart display system that integrates custom software for calibration including multiple target calibration's which can be loaded to adjust the display while loading the associated ICC profile, Apple (and few other products aside from Eizo) cannot do this. To quote from the manual: “SpectraView communicates with the display monitors using Display Data Channel - Command Interface (DDC/CI) which is a two-way communications link between the video graphics adapter and display monitor using the normal video signal cable. No extra cables are necessary. All adjustments to the monitor settings are done automatically using this communications link. It is not necessary to manually configure the monitor as all of the necessary settings are made by the software“. Apple has nothing like this, nor can 3rd party software you have to pay for extra do this. 9. SpectraView will bundle a custom mated Colorimeter with their software for calibration, Apple doesn't. The price you pay for software and colorimeter with the SpectraView, depending on what country you live in costs significantly less than buying the hardware and software for a non SpectraView. And that extra money will not provide a fraction of the capabilities outlined. 10. SpectraView PA series offer the ability to calibrate WITHOUT a Colorimeter with the FREE Multiprofiler software since each panel is measured with a very expensive spectroradiometer and that data is embedded in a chip in the panel. It can update the calibration as the unit ages to ensure calibration. Apple has nothing like this. 11. SpectraView can emulate with a single click other behaviors, again on the fly, so it can simulate a non wide gamut display (sRGB) among other standardized behaviors (Broadcast Video DICOM, etc) 12. SpectraView has internal electronic control over contrast ratio, Apple and few others provide this. Real useful for soft proofing on media that has differing contrast ratio's (matt vs. glossy papers). 13. SpectraView has Network support (Windows only). Apple doesn't. 14. SpectraView has provisions to lock the display controls so no accidental alteration to behavior by mistake. Apple doesn't. 15. SpectraView displays allow the user to raise and lower the display for best viewing position AND it can be rotated 90 degrees for Portrait. Apple doesn't provide this. 16. Several SpectraView's support Picture in Picture (you can have two differing calibration's per picture). Apple has nothing like this.

Thanks Andrew. I use SpectraView II with an NEC PA272w and an NEC PA271w. Just wondered. D

Nope. Plus i1P isn't even close to best in class for this task. Many of the advantages I outlined for the SpectraView system are the combination of both hardware and software designed to work together, making it a 'smart monitor' ala the old PressView/Barco/Sony Artisan products of the past.

Was David talking about an i1 Pro or an i1 Display Pro?

If an i1 Pro is so inadequate what instrument DO you recommend for profiling a professional grade monitor like an NECs or Eizo?

I believe he was generally asking about the capabilities of i1P and an iMac versus a SpectraView. An i1Pro Spectrophotometer isn't inadequate and is actually a better device IF (big if), you've got a colorimeter that isn't 'tuned' for the type of display being measured. In the old days, when wide gamut displays first came to market, this spectroradiometer was the only way to deal with them. But I'd agree, a colorimeter is a better option if it's designed for the display. Better for measuring dark emissive colors. See: http://www.lumita.com/site_media/work/whitepapers/files/xrite-wp-3a.pdf I'm using an i1Display Pro on my SpectraView but years ago, I used an i1Pro when they first appered.

If you've got both instruments and ArgyllCMS, you can have the best of both worlds. You use the spectrometer (i1 Pro) to build a "tuning" map for the colorimeter (i1 Display Pro), after which the colorimeter remains as fast as before and as superior for the shadows, but it "borrows" the color accuracy of the spectrometer.

Can do the same with SpectraView software too. Steps: 1. Connect the i1Display 2. Select the desired Target in SpectraView and calibrate the display. 3. Confirm that the calibrated white point is acceptable (judge 100% white only). 4. Disconnect the i1 Pro and connect the i1Display. 5. Open the SpectraView Preferences dialog. 6. Re-detect the color sensor. 7. Change the "Primary Colors Chromaticity Source" to "Factory Measurement" 8. Click OK. Next you will create a new Target with a custom white point that has been adjusted with the offset between the two devices: 1. In SpectraView, click the "Edit Target settings" icon. 2. Click the "Edit..." button in the "White Point" group. 3. Click the "Measure" button and measure the white patch on the screen using the i1Display. 4. The CIE xy values should be filled in automatically. 5. Click OK. 6. Click OK. 7. Enter a new name for the Target file. 8. Make sure the new Target is selected, and calibrate using the i1Display. The white point should match what you got with the iOne Pro, and the greyscale should be much better. Andrew Rodney http://www.digitaldog.net/

i1Pro is terrible. You can improve it from terrible to really mediocre by leaving it to warm on the screen for twenty minutes before attempting a calibration. We use BasICColor Display and the BasICColor Discus to calibrate NECs and on Apple 27” LEDs too. Does a great job — especially as it allows us to hardware calibrate NEC’s cheaper PA241 and PA271 panels. The money you save not buying into the “Spectraview" name is much better spent on a Discus ;-) -- Martin Orpen Idea Digital Imaging Ltd

Martin, I know the monitor has to be on for a while but how does leaving the sensor on the screen affect performance? Would it not warm up just sitting in the cradle? Does the light have to be on? This would suggest that you need to a few 'dead runs' before accepting the final result. A time-consuming exercise for sure. I've been told that the ColorMunki performs better at this task. What's your response? I have also been told that the Eizo monitors with the built-in sensor perform well in this respect, probably because they have been factory calibrated to the monitor. Have you any experience with them? Mark On Fri, May 29, 2015 at 5:20 AM, Spinnaker Photo Imaging Center < spinnakerphotoimagingcenter@dnmillerphoto.com> wrote:

I actually do this: 'leaving it to warm on the screen for twenty minutes before attempting a calibration’. I kind of figured this out on my own. Sometime back someone also suggested this….might have been regarding reading target patches for Printer Profiling. For the printer profiling, I do it twice just to warm up the 1iPro version D. Again, using i1Publish.
