Update: Are Canon IPF printers any reliable?
by Roger Breton 10 Jan '13

Warm thanks' to everyone that responded on and off-list. I got some wonderful insights. I still have not made my mind yet but, as I am checking prices today -- I hate to acknowledge that money plays an important part of my decision --, but I see 24" Epson printers that are selling at bargain prices, way below Canon's and HP's :( See here: http://www.vistek.ca/results/ProPhotoPrinters/printers-inkjet-wide%20carr/Wi de-Carriage.aspx According to this page (those of you in the US can probably find even better deals than this), I can have a 7900 for $2600 cdn while the 4900 is selling for almost $100 cdn more? Something's fishy because similar carriage width Canon's and HP's will run me $1000 to $1500 more? Economics.... / Roger

Reading ambient light using an Eye-One Pro
by Peter Constable 26 Sep '12

26 Sep '12

List-members- In the past, I've used i1 Share to acquire spectral data from ambient light sources using the Eye-One Pro and it's ambient light filter. i1 Share won't run on Lion. Are there any suggestions for Lion-compatabile software that will grab spectral data from light sources? I know of Canon's Light Source Measure Tool but that will only provide degrees Kelvin (as well as illuminance). Regards, _peter

Better if they told us what rendering intent they force on the conversions and if BPC is used or not. They do supply a CMYK profile... and they recommend Perceptual with BPC. http://www.blurb.com/downloads/Blurb_ICC_Profile.icc http://www.blurb.com/guides/color_management/image_prep_pdf Of course, if you submit a CMYK PDF, you can do the conversions to their color space any way that you want. > This is a bit like many consumer RGB lab workflows where you’re told you have to supply documents in sRGB but to make you feel like the lab is color management aware, they will send you a profile to soft proof you can’t use anywhere else. Sure, but even Costco can give you specific profiles for each printer/paper combination in each store - you can get an incredible match with some pretty elementary color management. (See, for example, http://www.drycreekphoto.com/icc/Profiles/Arizona_profiles.htm#AZ) Costco is a best-kept-secret for many wedding photographers. I've used it, with FTP submission of images converted to their printer space, with great results. Easy, cheap and accurate. > Nor do we know if the profile even reflects the print conditions. I’d prefer if labs like this would just stick to novice, non color management practices and just force you to send them sRGB and skip the silly soft proof exercises. Or better, just implement a true color management workflow as many labs do; supply the actual output profile(s), let you use it to convert your data as you please and post edit that data if you desire. My vote is for the latter. Users should hold Blurb to the fire... until they get a reasonable match. And given that Blurb does provide a profile, I'd use that for soft-proofing (in Photoshop), and if the hardcopy differs significantly from the soft proof, pressure them to re-print. It's just unfortunate that you can't do an accurate soft-proof from LR. Blurb does have a page devoted to color management: http://www.blurb.com/resources/color_management They also note: "At this time Adobe Photoshop® is the only application that we support" They need to do some work to get the LR interface up-to-speed, including documenting a reasonable workflow. --Rich

I want my Adobe 1998 hehehe
by Mark Nelson 30 Jul '12

Is there any information out there yet on Color Management with Mountain Lion and Photoshop CS6? I was trying to get to "no color management" by doing a "null transfer" by setting the printer profile to Adobe RGB 1998 and it's not listed!

Trouble reading ColorSync-users messages on iPad

I solved the problem by changing my Colorsync Users preferences from Mime encoding to plain text. This last digest (only two messages) came through fine on my iPad. If I have problems reading messages in the future, I will mention it, but I think this is probably the answer. thx, Lou Sent from my iPad On Jul 28, 2012, at 2:00 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 > https://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.

Trouble Reading ColorSync-users messages on iPad
by Louis Dina 27 Jul '12

27 Jul '12

I'm curious if anybody has had trouble reading the Colorsync-users mailing list on an iPad. Maybe I have some settings incorrect, but I get the normal Colorsync headers, list of messages and who sent them, etc. But, right after the initial list of messages and the authors, I get the following for each individual message: "This message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. message/rfc822" If there were 8 messages in that particular mailing, the above repeats itself 8 times. At the bottom of my iPad Mail page, it says "This message is only partially downloaded." I click on the "Download remaining 17.7 KB" bar, and the gear spins, but nothing ever happens. I can read the messages fine in Gmail or using Mail on my Mac, but not on the iPad. Any solutions or suggestions? Thanks, Lou

Epson 4900 driver 8.66 MAC OSX 10.7.4
by Giuseppe Andretta 26 Jul '12

26 Jul '12

Hi all I have problems with my Epson 4900. All prints come out posterized and it really looks like a double conversion occurred. I printed excellent prints untila a couple of weeks ago with standard profiles and custom ones made by me. At a certain point it started to print very posterized prints so I tried to avoid it changing the custom profile (i print from Lr4 under Mac OSX 10.7.4) and switching to factory profile for the Premium Luster: same posterization. I upgrade the driver with the latest one (8.66) and I tried with it: same story. I tried with a workaround for not managing color and see what happen...I printed from Preview and from Adobe Color Printer utility just to see what's going on: same posterization even with no color management. I tried from Mountain Lion and driver 8.66: same posterization I don't know what else to do...any idea? Giuseppe

I think it helped in my case. Mark, What RGB profile "roughly simulates high quality offset printing (e.g., the "GRACoL2009" they refer to)? Why not use Photoshop (even an older version) and the correct profile to soft-proof the images? If an image soft-proofs badly, fix it, re-import into LR and send it off... That seems better than trying to force LR to do something it's not designed to do (soft-proof CMYK). As for rendering intent, there's probably not a huge difference, and this is a crude check anyway, as the Blurb quality control is questionable to begin with. Using LR seems like trying to eat soup with a fork... --Rich Wagner
