Issues with v4 profiles that include CXF Data
by Marc Aguilera 13 Aug '12

13 Aug '12

Hello All! I have been using X-Rite i1 Profiler version 1.3.2. and have building many wonderfully accurate RGB and CMYK output profiles and so far have been very pleased. I have just ran across two situations that have made me pretty frustrated. I have recently built two CMYK profiles that are giving me headaches. 1. I built a CMYK profile to be imported into Roland VersaWorks Version 4.0 which accepts all v4 ICC Profiles. I included .CXF data in the profile mostly because it was the default option in i1P. It would not import into VersaWorks, and the only way to get it to import was to disable the inclusion. I was ultimately able to solve this issue, it's the next issue that has me stumped. 2. Now the same might be true for EFI Fiery Command WorkStation 5 and a Docucolor 252. I built a v4 CMYK profile with .cxf data then uploaded to ColorWise as a destination ( output ) profile and it seems to have crashed the Fiery completely, not even allowing me to login. Has anyone had a similar experience? So far I guess the moral of the story is "Don't build v4 ICC Profiles with .cxf data". Can anyone tell me different? Thanks!

dE tolerance for PMS solids?
by Terry Walker 08 Aug '12

08 Aug '12

Hi all, We publish a library of books with a different PMS background color for each year. We have 14 PMS colors picked for this and have printed them now for 11 years. When we started out we didn't have a spectro to measure them with and over the years colors have drifted thru new ink companies, papers, etc. and just plain on press variations which seem to be worse lately. We now have a spectro and can measure the Lab values of these inks and have a "good" reference point to use going forward. My question is, I know the press printing tolerance for cmyk solids for Gracol is dE of 5, what would you suggest for press tolerance of Pantone solids? Most all our colors are darker shades. Some of our main PMS #s are 5605, 5255, 229, 140. Any suggestions on what would be an acceptable dE range for these?

Their 65k cousins were probably spectrally better, but visibly blue to our eyes. These are green (though they do read bang on 5000k on the spectro). And spiky compared to the Just Normlicht tubes in our view booth.

Hello Eric, Thanks for your reply. Of course I am familiar with the new revision of 3664, it was a hasty email on Friday afternoon and I should have offered more details to be clearer. I am interested in 'Hardware Store Tubes' not so much for critical viewing but rather to use in a factory nearby presses and other areas where colour critical appraisal will be conducted. At a plant last week i used Babel's CT&A to show a customer lights on all their presses needed updating. Around the press area all the 'industrial tubes' are old and yellow and I was able to measure them and deduce these tubes were in fact influencing the results on the press console. I thought if there was a off the shelf tube at a reasonable price, which does not too badly influencing the critical viewing area, it would make sense to use these tubes in the areas surrounding the presses. It might be the model mentioned was "Philips TL-D-90" Anyone using a specific specification for around the presses, but not critical viewing?

Hi Lou, You can use X-Rite ColorPort 2.0, if you don't have i1Profiler. The download for the software is under Support. http://www.xrite.com/product_overview.aspx?ID=719 The steps are to (1) create a test chart with the number of measurements you want to make, (2) take the measurements, (3) save the measurement file as Tab Delimited and choose the colorimetric and spectral data you'd like. You can then open the data in MS Excel. All the Best, Tom ________________ Tom P.

Robin/Derek...thanks for the software suggestions. I'm not ready to part with the money for the simple spot readings tasks I currently need to perform. Babelcolor PatchTool and SpectraShop do a lot more and may be just what I need down the road. I will keep them in my memory banks for when I need more flexible and power tools. Scott, thanks, ColorPort did exactly what I needed and it is free. I just needed to check some numbers for neutrality and density. I was under the mistaken impression ColorPort required you to create a formal reference file before taking spot readings, (which it does, sort of), but your are correct...just select any old predefined chart, start taking spot readings (even if they diverge wildly from the reference data) then view the data using the "Info" button. You can view colorimetric, spectral, density, spectral graph, status T/E/A, Lab, LCH, XYZ, etc. It's basic, but it did the job I needed to do. I never bothered trying take spot readings, since I thought I first needed a reference chart that was in the ballpark to identify the data, but you don't. Thanks for the tip. Lou

What software are people using to take spot reflective readings using Lion or Mountain Lion with an Eye-One Pro? (version 1) I have used MeasureTool, Color Picker and other software, but they don't work under Lion. I'd prefer some FREE utility that is easy to use and allows me to read L*a*b* at a minimum. I can boot from a saved Snow Leopard partition, if necessary, but I prefer a replacement for future compatibility with the newer OS. Thanks, Lou

"Hardware Store Tubes"
by Dan Wilson 03 Aug '12

Hi Forum, Attempted to find this information searching the ColorSync archives but that was not as easy as I hoped. I recall someone reporting on their testing 'off the shelf fluorescent tubes' for use in colour viewing. I even recall a screenshot of the specifications printed on the Tube. Can't find it anywhere on my computer :( Is there an 'off the shelf fluorescent tube' that performs well? Thanks in advance, Dan Wilson
