30 lpi silkscreen w/ DTP 20: Averaging suggestions?
by andre ribuoli 21 Sep '11

21 Sep '11

Hello Group, I was curious if anyone had a good suggestion for averaging the Xrite DTP20's readings for a low 30lpi halftone color target made with 4 color screenprinting? I do know Xrite's newest solution has an average feature, as do some older programs like ProfileMaker. The Pulse ColorElite does not, however, I could average using ColorPort, taking individual numerical readings and averaging with Excel or similar. I'm hoping there is a utility or program that does support the Xrite DTP20, allows targets to be read multiple times to compensate for low res color swatches. Any suggestions other than buying a new CMM setup or taking the laborious route of manual readings? :) many thanks Andre Ribuoli www.ribuolidigital.com On Mon, Sep 19, 2011 at 3:01 PM, <colorsync-users-request(a)lists.apple.com>wrote: > Send Colorsync-users mailing list submissions to > colorsync-users(a)lists.apple.com > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.apple.com/mailman/listinfo/colorsync-users > or, via email, send a message with subject or body 'help' to > colorsync-users-request(a)lists.apple.com > > You can reach the person managing the list at > colorsync-users-owner(a)lists.apple.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Colorsync-users digest..." > > Today's Topics: > > 1. measuring ambient spectrum (and eye one share) (Robert Crow) > 2.

Re: measuring ambient spectrum (and eye one share)

Thanks for all the replies, some really useful information to follow up. With the encouragement of Dana, off list, I have got the unsupported power PC version running under Snow Leopard! It requires not just Rossetta but another crucial step which I missed out... Turn the computer off and on again after installing! (I know, I know! 101). Thanks also to José who replied off list with the link to Canon's Light Source Measure Tool, which I had not heard of. No graph as he pointed out, but still useful for ambient light measurement. http://software.canon-europe.com/software/0038349.asp I am away from the spectro at the moment, so will fully test all this with the device tomorrow. All the best, Rob.

good value in monitors?
by Armand Rosenberg 19 Sep '11

19 Sep '11

Could anyone recommend a reasonably priced, reasonable quality monitor for photo editing? I'm looking for good value, not top of the line. Size of 27-30" preferred, but 24" might do. Thank you, Armand

measuring ambient spectrum (and eye one share)
by Robert Crow 19 Sep '11

Hello, There used to be a bit of free Gretag software called 'Eye One share', which allowed one to measure the ambient light - using an Eye One Pro - and display it's spectrum as a graph (spikes and all!) X-rite no longer seem to offer this. Does anyone know of an alternative (preferably free!) that will run under Mac osx Snow Leopard? Thanks, Rob.

Re: Converting current profiles for old OS versions
by Jonathan Taylor 16 Sep '11

Thanks all for the helpful answers. I just spent a productive hour testing some of the suggestions. Blue Eye Pro has an option to make a version 2 profile, and I found in the Advanced section that it was already set to "Matrix-Profile." (The other option was "LUT-Profile." Can anyone tell me what the difference is?) As predicted this created a profile that could be used on 10.6.8, 10.5.8, 10.4.11 and 9.22. Is there anything I am losing by using a v2 instead of a v4 profile? Any concerns with v2 and my wide gamut monitor? BTW, all Macs are connected to the monitor with DVI through a DVI KVM. Although no one has commented on it so far, doesn't the fact that my monitor has its own hardware LUT also help ensure that four Macs can share the same profile? Wouldn't the monitor harware LUT also make this setup work with analog/VGA connections, since the video card shouldn't be involved? jt On Tue, Sep 13, 2011 at 3:13 AM, Matthew Ward < matthew(a)matthewwardphotography.com> wrote: > > On 12 Sep 2011, at 03:28, Jonathan Taylor wrote: > > > ***[To cut to the chase, here's the question]*** > Can I-- and how do I-- convert a monitor profile created by Lacie's Blue > Eye > Pro software (v1.0.16) under 10.6.8 to a profile format that OS9 will > recognize? > > > There are essentially 2 sorts of profile, V2 (version 2) and V4 (version > 4). > If you are creating v4 profiles with your software they are not backwardly > compatible. > If you create a v2 profile OS9 should see it. > You may or may not be able to specify which type of profile to create in > your software. > I am not aware of any way to convert a v4 profile into a v2 using software. > > Best > Matthew Ward >

There are essentially 2 sorts of profile, V2 (version 2) and V4 (version 4). If you are creating v4 profiles with your software they are not backwardly compatible. If you create a v2 profile OS9 should see it. You may or may not be able to specify which type of profile to create in your software. I am not aware of any way to convert a v4 profile into a v2 using software. Best Matthew Ward

Converting current profiles for old OS versions
by Jonathan Taylor 12 Sep '11

12 Sep '11

Hi all, [Long story version that can be skipped] I'm a photographer who runs a bunch of old film scanners (with accompanying Macs), but I do all my real work on a calibrated wide-gamut LED Lacie 724 display and Mac Pro running 10.6.7. With Vuescan I can run most of my scanners under Leopard on a G4 and a G5. I have a KVM that lets me share the display between the Mac Pro and my G5 and G4, and so when I update my calibration I can just copy the new profile from the Mac Pro to the G5 and G4. The problem is that I'm bringing a Howtek 4500 drum scanner into my workflow and apparently the best software may be the Trident 4 package that only runs under MacOS 9. Although I think color management under OS9 is pretty decent it won't recognize my monitor profile that comes from 10.6.7, so... ***[To cut to the chase, here's the question]*** Can I-- and how do I-- convert a monitor profile created by Lacie's Blue Eye Pro software (v1.0.16) under 10.6.8 to a profile format that OS9 will recognize? A more broadly related question, what are the relevant Colorsync and ICC profile versions associated with different OS releases? I just checked the wikipedia colorsync page and was disappointed. For instance I've also found that Tiger doesn't recognized my monitor profile. It couldn't possibly be using the same Colorsync profile version as OS 9.2.2-- or is it? It would be interesting to see a table for Mac, Windows, and any other relevant color manged operating systems. jt

Atkinson Profiles
by Randy Zaucha 11 Sep '11

11 Sep '11

All I can say is that I had a few treasured visits at Bill's place right after he made those profiles for the 9600 Epson. The ABC's of color management tell you that if you use the same printer/paper/ink combo that the profile will still be valid. Bill, as the stellar engineer he is, wanted to make the absolutely best profiles that could be made for the printer he had at the time. The process involved thousands of samples which involved his getting up in the middle of the night to put another chart on his Spectrolino. He told me he was dealing with the "warbles" in the gray balance of the device. Personally, I have physically read individual patches of color charts in the early days, but Bill went waaay beyond this. I actually saw him explode an Epson engineer's head explaining his technique at a trade event. I recommended a photographer friend to buy an Epson 9600 just because of the superb quality of Bill's profiles. He told me years later that it was a terrific printer and that other photographers used to bring their files to him to print because of the quality. I tested the gray balance on it and it was GRAY. My guess is that your 9600 is not in tolerance to manufacturer's spec or there is an operating system/application version issue. Randy Zaucha Managed Color

At the time of the 2100 (which is the 9600 tech) I regularly had calls from clients to tell me their prints were turning green. I saw it happen on my own device too. This was a driver corruption issue, and could be fixed by reinstalling the driver. Although I most assuredly don't have the abilities of Bill Atkinson, I do assure you that running a profile with one of Bill's larger targets with 4000 or so patches will produce a perfectly usable profile for the 9600. Anyone on this list including me can do that for you, it has got much easier since the iSis XL came on the market. Edmund
