Display suggestions

Hello everyone, Our department has a rotating workstation replacement cycle; and this year our design staff is next in line for new equipment. One question that has come up is whether or not is is necessary or advisable to replace our existing displays along with the Mac towers. In 2102 – when we last got new Macs – we also purchased NEC MultiSync PA241W displays to go with them. We have been happy with their performance; but are wondering if the age of the displays might make it worthwhile to get new ones while we are in our update window. If not, we will most likely tied to the NECs for another 4 years until the cycle makes full turn. Does anyone know if the PA241W has a "shelf life” for lack of better terms? Is it advisable to upgrade displays at this time? If so, can anyone suggest displays that have comparable performance at the same price point? Thanks, Dean Dean Mackey Senior Graphic Designer Creative Services | Rice University | Allen Center, Suite 200 - MS 95 | 6100 S.

Hello Roger! Please can you share the PDF file to take a look on it, I'll try to search in my archive.

Color science primer
by Brian Aderer 28 Jan '16

Hello all I have been quietly following this group for some time. I'm a photographer and drum scanner operator, and I would like to improve my understanding of color theory. Currently, I loosely understand what to do from a workflow perspective, but the why of a lot of it eludes me, and most of the discussion on this board is over my head. I wonder if anyone could recommend to me a primer text on applied color theory. Best Brian Aderer

ESKO ECI2002 EyeOne iO

I have some press sheets printed with this target that uses a non-standard layout I'd like to read with my iO table but I don't have access to the ESKO software - we can't all be rich ;-) I have obtained an exported CGATS file and a PDF of the target in this layout but, alas, none of my pet tools are able to do their magic on this file. I'm faced with the prospect of manually reordering the 1280 patches in Excel . I finished the "first row", just 29 more to go :( Any suggestions? Or if you happen to have the corresponding Reference file, please contact me offlist. Best / Roger Breton

ColorAnt and Colorthink Pro. Or if you happen to have the EFI XF RIP, Color Tools has a nice tool for this. You need to set up your printer as an output device in the System Manager window first.

Hi Derek You can use ColorThink and import the whole list into a worksheet and get delta e reports. To get the Pantone colours you can export from i1Profiler software. regards Malcolm Today's Topics: > > 1. Pantone colors match (Derek) >

Re: Does MF color slides scanning in 24 bit still make sense
by Mike Strickler 23 Jan '16

Ernst, the article you link to requires a paid membership to read it, unfortunately. As for Callier effect with color negatives, well, it would have to be a problem with the surface, presumably on the emulsion side, as dyes to not scatter light as do silver grains in black and white film. These surface effects are dramatically reduced by liquid mounting. Aliasing of the grain image, on the other hand image can greatly increase its coarseness. This is a product of sampling frequency and grain pattern, and certain combinations of fim type and aperture size/sampling rate can aggravate the effect. Contrary to common belief using a smaller aperture may actually smooth out the grain by avoiding the frequency at which the aliasing is worst. Why negatives and not positives? They have a sharper grain pattern than positive transparencies, that's all. I've had little trouble matching the look of sharp optical enlargements in digital prints made from drum scans of the same color negatives. > Message: 5 > Date: Thu, 21 Jan 2016 17:15:19 +0100 > From: Ernst Dinkla <info(a)pigment-print.com> > To: MARK SEGAL <mgsegal(a)rogers.com> > Cc: "'colorsync-users?lists.apple.com' List" > <colorsync-users(a)lists.apple.com> > Subject: Re: Does MF color slides scanning in 24 bit still make sense > Message-ID: > <CAMzUcR1drLRTgv8ApbDiakEo5tC2SDxh=36zZmfD0oPTWxxAFg(a)mail.gmail.com> > Content-Type: text/plain; charset=UTF-8 > > You mean the Callier effect as mentioned earlier in one of the messages.
