by Steven Kornreich 20 Apr '18

20 Apr '18

Does anyone have in the attic have an old Spectrolino that there not using anymore? I think mine has finally died. I tried using Gretag Download Utility and it does show my Spectroscan, yet no SPectrolino. I have had this setup since 2001 wow…. And I have been using color port to read charts then import the data into i1 Profiler. ________________________________ Steven Kornreich steve(a)kuau.com http://www.kuau.com

Two laptops Two colorpicker results

Thanks to all who responded. I am a bit embarrassed to say I was confused about the color picker and thought that the Adobe Color Settings dictated the numbers displayed. You were all correct that the file's profile identity controlled the numbers in the picker. I was occasionally using a Prophoto embedded color chart so this caused my confusion as I usually am in Adobe RGB. It also did not help using a Mac based application and Photoshop on the PC.Living and Learning as Always,Randy Z

Epson canned profiles
by Steven Kornreich 19 Apr '18

19 Apr '18

I am using the canned printer profiles that came with my Epson P5000 my question is when setting the “Output Resolution” by default it brings up SuperPhoto 1440 DPI, Super MicroWeave, and High Speed” Should I be changing any of those setting? I assume when Epson created the profiles thats how the printer was setup or does it not matter? Thanks ________________________________ Steven Kornreich steve(a)kuau.com http://www.kuau.com

Thank you for this contribution, Walker. A nice break from the preening & shouting …er, discussion I mean. I’ll try not to resent your criminal behavior in buttering your toast upside down. ;-) John P.S. Toast - what a perfect device for this list! Were you remembering Steve Upton’s famous toast metaphor for the problem of color reproduction? > On Apr 17, 2018, at 6:03 AM, colorsync-users-request(a)lists.apple.com wrote: > > Message: 8 > Date: Tue, 17 Apr 2018 09:02:07 -0400 > From: "forums(a)walkerblackwell.com <mailto:forums@walkerblackwell.com>" <forums(a)walkerblackwell.com <mailto:forums@walkerblackwell.com>> > To: ColorSync <colorsync-users(a)lists.apple.com <mailto:colorsync-users@lists.apple.com>> > Subject: Re: Epson canned profiles > Message-ID: <8A5F94BA-BD9B-4453-B00A-9C9A7A74F7EF(a)walkerblackwell.com <mailto:8A5F94BA-BD9B-4453-B00A-9C9A7A74F7EF@walkerblackwell.com>> > Content-Type: text/plain; charset="utf-8" > > Whenever I see flamewars like this on ColorSync forum I’m tempted to post this little cartoon: theoatmeal.com/comics/believe <http://theoatmeal.com/comics/believe> > > Hopefully it calms people down a little. > > For some people (and their business) minuscule dEs are a real problem. For other people and their business it’s no problem at all. It’s just a matter of what world one inhabits. If you inhabit the "dE differences of .85 at the 6ish L value level make no difference”-world then it does not discount all the people who that would make a huge difference to. Same goes in reverse.

I would say a lot of the people who post on this forum are people from the “minuscule dEs are bad” mindset. I include myself in that. But it’s important to remember that people have different contexts. > > My personal experience is this: After I made my first good custom profile for Epson I never went back to canned profiles.

Two laptops, two color picker results for same spot
by zbet66＠yahoo.com 18 Apr '18

I amhaving an experience that I'd like to figure out. I am getting two differentcolor picker readouts for HSB and RGB for the same Pantone spot color on Mac and PC laptops. The Lab and CMYK numbers do match. Pleasenote that all the color management preferences (color settings) are the same on both laptops. Laptop 1:Windows 10 PC Photoshop CC v19.1.0 RGB Default is Adobe RGB Laptop 2:MacBook Pro Mac OS 10.13.2 Photoshop CC v2017.1.0 RGB Default is Adobe RGB Laptop 1,color picker, (example) Pantone Purple RGB= 165,45, 181 CMYK= 35C, 88M, 0Y, 0Y HSB:293/75/71 Lab: 47/69/-42 Laptop 2,color picker, (example) Pantone Purple RGB= 144,65, 160 CMYK= 35C, 88M, 0Y, 0Y HSB:290/59/63 Lab: 47/69/-42 Laptop 1,color picker, (example) Pantone 802 RGB=128/212/69 CMYK= 67C, 0M, 100Y, 0Y HSB: 95/67/83 Lab: 75/-63/63 Laptop 2,color picker, (example) Pantone 802 RGB=117/189/73 CMYK= 67C, 0M, 100Y, 0Y HSB:97/61/74 Lab: 75/-63/63 This istrue of all spot colors. (both are Pantone+ Solid Coated library) Why? The PCversion looks to be correct. Why is the Mac version giving different numbers inRGB and HSB? Randy Zaucha

Andrew, you can't help but turn up the heat even when opportunities for agreement come up - you enjoy jerking peoples' chains. Can't you ever at least try to be less argumentative and give dialogue a chance to lead to understanding? "I win, I win" - sums it up so far. There are important things that could have been learned from this thread but they've been lost and readers that may have had an interest in this are likely giving up. Glad you're having fun.

PANTONE libraries are distributed in CIE Lab form. Unless the same ICC profiles with the same RI are used on both platforms, there are bound to be differences in RGB / HSB. / Roger -----Original Message----- From: colorsync-users [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of zbet66(a)yahoo.com Sent: Wednesday, April 18, 2018 3:53 PM To: colorsync-users(a)lists.apple.com Cc: Glynn Hartley <glynn(a)specialcolor.com> Subject: Two laptops, two color picker results for same spot I amhaving an experience that I'd like to figure out.

There used to be specific OEM printer profiles that corresponded to the print quality resolution settings for the older Epson wide formats like the Stylus Pro 9000. I think that extra variety in profiles was abandoned when the 9700 range appeared, so the 9600 and 10600 may still have had them. I guess some compensation in the underlying media presets can help to make one printer profile usable for more resolutions.

The resolution setting and the high speed, etc. can affect the color output a little bit, but probably not much. The default settings are most likely what the profiles are made to represent. So stick with those if it works for you. But if you have a need for a higher resolution or something, go ahead and try a print. You’ll get an idea of how much difference (if any) you’ll see by first-hand experience.
