profiling back-printed plexiglass?
by Randy Norian 12 Dec '16

12 Dec '16

Good afternoon! It’s quite likely that this has been covered before, however, I have to ask. We are attempting to print high quality images on the back face of clear plexiglass, with a white ink layer behind the image. The print engine in question is a Rastek H625 (by EFI) UV-cured inkjet. While I can color manage paper prints with this device, the backside-plexiglass printing has me stymied. The images are extremely bright and overly-contrasty, to the point of being unacceptable, especially as companion pieces to other latex work we’re doing. I thought I’d just characterize the output on the plexiglass, however my ES-2000 won’t read the swatches through the plexiglass, for whatever reason — it simply faults out. I’m using EFI color profiler suite 4.6. Have any of you faced the same issue? Any advice on how to go about color managing this sort of printing? I know I have to figure out how to read these swatches, but beyond that, are there any caveats for working with "back side of glass” printing? Many thanks- Randy Norian

In-browser monitor profiling?
by Jeff Nova 07 Dec '16

07 Dec '16

Remember how e-Color used to permit users to calibrate and profile their monitors in-browser, and stored the result in its extension? Well, that company is no more, and the tech seems to have been laid to rest. Is there any solution for color management on the web that is on the monitor side? I know color management has grown incredibly with browser support and OS support - only Chrome on Android and Android specifically are still not color managed - but that doesn't mean we can count on a good monitor profile. Anyone know of a solution?

Photoshop History Logging broken
by Martin Orpen 08 Nov '16

If Photoshop’s History Log feature is important to you, don’t upgrade to 2015.5 as it’s broken. The first log entry made in 2015.5 is the last log entry you’ll get :( Creating a new log doesn’t fix the problem. Logging will only work for the duration of the current session and then break as soon as you quit PS. -- Martin Orpen Idea Digital Imaging Ltd

Fiery XF only has HT driver to Epson 7800. I've never once played with an HT driver. If I create epl using CMYK color mode instead of CMYKcmkk color mode will the Epson driver internally still use the light inks? thanks -- Dan Bergstrom | Color Technology and Quality | PRIMARY COLOR ORANGE COUNTY http://www.primarycolor.com<https://webmail.primarycolor.com/owa/redir.aspx?C=51c888e17de443a98e67cfca7…> | T 949 660 7080<tel:949%20660%207080> C 949 616 4986<tel:949%20616%204986>
