On doing a nice GREY with CMYK

Hi guys,
I know if I need a good solid and dark black i can always use an "enriched black" let´s say
C=50, M=0, Y=0, K=100
I am doing a design which i will need a strong GREY, let´s say 80% black. The problem with that something the grey does not cover that well. The client told me to use CMYK so no pantone ink will be available for that. The question is how to get a good and strong GREY with CMYK? If i put more Cyan as the enriched black the color will turn and it will not be straight grey, more of a bluish grey.
Any ideas? Thanks for the help,
Sebastiao

There is no set cmyk value for rich black, it is different for each output scenario. That is what colour management is for.
If you start with a neutral LAB value (as I understand it) then convert to a printer's profile, you should theoretically end up with a neutral on press.
From a printer's point of view, that is only a starting point and I would advise the pressman exactly what you are looking for as he will adjust press settings to balance the colour for current conditions which are unpredictable in all but the most specialised printeries. For a general commercial printer, you should make sure they understand what you are looking to achieve and start with numbers that will make that possible as mentioned at the top.
For the record, my personal preference would be a max colour of about 60/40/40/90 which would bias the grey to the cool side but give plenty of weight to work with....

Why does my Mac boot with a Grey screen and a globe?

Why does my Mac boot with a Grey screen and a globe?

Usually means you don't have a bootable system installed so the OS is looking for a bootable system on the network.
Does the computer eventually start up shortly after the globe appears? If so then open Startup Disk preferences, select your boot volume and click on the Restart button. If this is not the case then you need to reinstall Snow Leopard.
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

I restared my Iphone 4s and now my photos are just grey with JPG in it. How do i get my photos back?

I restared my Iphone 4s and now my photo's are gone. They are just grey with JPG in it.
How do i get my photo's back? And why are they grey?
Any help would be nice.
Thank you.

Restarting your phone doesn't cause it to grey out.
Were you restoring from an icloud backup? IF so, it does take awhile for pictures to download.

PLEASE HELP. my 2007 macbook will not accept the reinstall disc mac os x 10.4.9 after i erased everything. the screen is grey with a flashing folder with ? on it. what can i do to fix it?

i erased everything from my macbook and try to reinstall the MAC os x 10.4.9. but now when i restart my computer the screen is grey with a file folder marked with a "?" flashing. when the dics is already already inserted and i restart it, regardless if i hold down the "c" or "d" key with rebooting, the disc is automatically ejected and then it goes back to the grey screen with the flashing "? folder".
if i was to try and reinstall the "for mac computers" os x 10.5.4 the computer will load the disc and bring me to the language select menu but as soon as i click the "next" button it tells me that the software is not able to be installed on that computer.
i have no clue what to do. the computer was working COMPLETELY fine before i erased something.

Yikes, what happens or shows if you hold the Option or alt key on bootup?
The 10.5.4 Disc at least sounds like a Gray Machine specific Disk, or wrong Partition Scheme!???
Does that one allow Disk Utility to run?
Did you Erase to GUID?

Pantone Colors with CMYK Colors?

Dear all!
I am LUCK. I am wondering about Pantone Colors with CMYK Colors. It's that I got 1 Pantone Color from my customer and then I changed it to the equivalent CMYK Color. Will I get different colors when changing from Pantone to CMYK because I will print with CMYK Printing Process? Anyway, I am wondering whether the Pantone color is the fix and specific color or not. I mean when I print the Pantone Color, I will get the same result as I print before. Is it right?
Please help to explain to me whether Pantone Colors will keep their colors the same and stable or not. Or would you mind telling me what kind of colors that can produce the same color every time I print, especially for the Formal Uses?
Sorry for being unaware of my knowledge here. Thanks a lot and best wishes to all!
I am looking forward to hearing from you.
My best regards,
LUCK

Pantone is a company, not a color. Pantone produces spot color inks, process color inks, and color references.
Understand first: Five color printing ("process plus one") is not uncommon, because six-color presses are not uncommon. When a project is printed on a 6-head press, it does not dramatically affect the costs, because the job can still be printed in one pass. Brochures and other marketing collateral are often printed in 5 inks when a company specifies a spot color as its identity color. When done right, the company's identity specifications also provide a CMYK mix to use in lieu of its spot color(s) when restricted to only CMYK (as in magazine placement ads).
So I'll assume your customer specified a Pantone spot color, and does not provide a preferred CMYK substitute, and your project is restricted to four color process (CMYK) printing.
CMYK mixes do not exactly match spot color inks; they can only approximate. How closely they can approximate depends upon which spot color you are dealing with.
Pantone provides its recommended CMYK values for approximating its spot color inks. That's why Illustrator provides a Pantone solid to process Swatch Library. But such lookups are recommendations; they are not absolute equivalents. There are many many colors in nature (and in spot ink pigment) which simply cannot be matched in CMYK. And any time you try to convert between color models (spot to CMYK, RGB to CMYK, etc.) you encounter ambiguities, because there are multiple algorithms that can be used to generate four values from fewer values.
I often find Pantone's spot-to-process recommendations to be unsatisfactory, and use my own CMYK approximations instead. This is not necessarily due to any failure or shortcoming of the Pantone libraries, but just differences that exist in specific printing houses and workflows. The printing process is full of variables.
Will I get different colors when changing from Pantone to CMYK
Yes, the colors will be different. But whether the difference is noticable depends upon the specific spot ink you are trying to match. It also depends upon the specific use of the color. Fact is, human color perception is very adaptive. Colors that are "mathematically" equivilant according to some colorimetric algorithm are not necessarily perceived as equivilant by human eyes, because much depends upon environment (adjacent colors, etc.)
You can refer to a printed process color reference against which you can compare a printed spot color swatch book and judge for yourself which CMYK values best approximate the spot color. Or, you can set up simple test sheet of your own, and have it printed to determine a "best match" in a particular printing environment.
All the above is just one reason why contract proofs are still important. If your customer is very picky about his spot color, then he needs to understand that converting it to CMYK is merely an approximation, and perfect matching is simply not possible. That's one reason why spot inks exist in the first place. If he is not willing to pay for five-color printing, then he will likely have to settle for a minor compromise.

Does Lightroom work well with hiDPI Windows 8.1 touchscreen ultrabooks?

Hi all,
My old laptop is on the fritz, shopping for a new one.
Apart from the Web, the application I use the most is Lightroom.
I've been interested in the nice new ultrabooks, but I'm wondering: does Lightroom work well with hiDPI Windows 8.1 touchscreen ultrabooks?
Is hiDPI advantageous, or actually annoying?
What can you actually use touch for in Lightroom, and does it improve your workflow?
Thanks kindly!

I am not 100% sure whether lightroom supports HiDPI on windows but on Mac OS X it is absolutely fantastic (I use a retina MBP). So I would see if you can try it out somewhere. My guess is that Lightroom supports it on Windows too and then I can highly recommend it.
No clue if touch works well or not for Lightroom. My guess is not as almost always using touch in applications that were not designed for it is very kludgey.

"Missing Profile - The doc does not have an embedded CMYK profile"

For the first time ever last Wednesday each time I open a file in AI - CS3 I get the same message: "Missing Profile - The doc does not have an embedded CMYK profile". I looked in library>colorsync>profiles and sure enough they were gone? I downloaded new profiles from Adobe, installed them in library>colorsync>profiles - and still the same thing with each file I open. I dragged AI to the trash, re-installed AI from my disc repeated the process with the same results - HELP!
I don't seem to be able to find any info on the Adobe forum, I realize I need to upgrade but for now what is the solution - Thanks in advance. Boatingislife!

Hi Larry, Thanks for your reply along with Muppet Mark, If I changed the color settings originally it was not my intension, I was simply just opening the next project to work on and viola’ “missing profiles”.
Attachment (picture) 7 was my last setting for color prior to your email, and yes I was messing around with this last night comparing it to one of our old G4’s, so I can’t remember where it started out before I got my hands on it.
Attachment (picture) 8 is my current settings based on your email recommendations.
Attachment (picture) 6 is the message I receive when I open any files created prior to these changes I just made. However after I open and resave the file I no longer receive this (picture 6) message.
My question is will my color be back to where it was before the problem started last week. In looking over one of the files I opened (I design/build transportation maps btw) most of the color is where I usually have it set however some colors were fractional as if they were converted from spot colors. SO I’m not sure what to do except go through all the known colors and make sure they are where I usually would set them, or do you have a better suggestion.
Oh by the way – for all you guys that are helping lunch is on me at McDonalds on Michigan St in Grand Rapids, MI!!

What does a white screen with a file folder and question mark indicate?

what does a white screen with a file folder and question mark indicate upon start up?

That the computer can't find a useable boot volume.
Boot from your grey installer DVD disc 1 (hold down the C key on startup or hold down Alt/option on start and choose the installer disc).
OK the language page (if present). From the installer screen, go to the menu bar and choose Disk Utility; depending on the OS version it may be in the Utilities menu or Tools menu.
In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.). Run Repair Disk (not Disk permissions). If problems are reported as repaired, run it again until you get a message in green "the volume seems to be OK".
If it says it can't repair the disc, you may need heavier guns such as DiskWarrior or TechTool to attempt a rescue.
Hope you have backups; retrieving data from adead drive can be expensive and tricky.

HP 10G "NC510F" NIC compatible with X2 10G tranceivers?

Specifically, does anyone know if the HP 10G NIC work with Cisci X2-10G-LRM or X2-10G-SR?
-Jim

Jim,
according to the datasheet for that NIC (http://h18004.www1.hp.com/products/servers/networking/nc510f/index.html), it says that it is "10GBASE-SR fiber optic".
The "SR" (short range) part here is the important part. The specifications for SR are standardized - so anything that is "SR" will interoperate.
so: the Cisco "SR" part will work fin, the "LRM" won't, as LRM is a different standard.
SR optics use multimode fiber - so you'll need that.
from memory, an Cisco X2 optical module has SC connectors, the HP NIC looks to be LC connectors, so you'll need a multimode patch cable that is LC-SC - again - something that is fairly standard.

Does Magic Mouse work with ipad air?

Does Magic Mouse work with IPad Air?

Yes, it is a Bluetooth device. However, my iPad will not connect to the mouse. Not sure why.
I use my iPad as my personal computer. Mainly for surfing the web, social media, paying bills online... I already have a Bluetooth keyboard that connects to the iPad, so thought it would be nice to have a mouse.

ZR65MC camcorder does not turn on with battery in position unless the power adapter is plugged in

Bought a ZR65MC camcorder in 2003. Enjoyed it so much, but a couple of yrs. ago, the tape compartment stopped opening. I just purchased another ZR65MC (used) on ebay in hopes that I could at least get the videos off & onto DVDs. Also, we are planning trip to Yellowstone soon, so camera/camcorder will be nice. Problem: The used one does not turn on with a fully charged battery unless the power adapter is plugged in. I assume battery is good because it turns on my older camera. I do need backup batteries in both, but have not done this yet. Please tell me I have not purchased a bad camera, maybe just doing something wrong? Would have never purchased a used camera online, but did this time. I have ordered a new battery BP-522 with wall charger. It should arrive next week. Any suggestions?

Hi Sharon72064,
If the new battery won't power the camcorder without the Compact Power Adapter, unfortunately, it's likely that an internal component has malfunctioned.

Iphone 5 screen turned dark grey with random lines, Help!

So I was playing a game on my Iphone 5 when all of the sudden I get to the boss. Then the Phone's screen starts turning dark grey with lines streacking across it in clusters and the lines moving randomly. Then after a few moments the phone was complety dark grey. If i pressed the lock button it would turn off and again turn on to the same screen. I could somtimes barley make out the power bar on the top. Lastly I tried restarting it by holding the lock button and the home button and then it just turned off and wont turn on.
Here is what I know that could connect with the issue:
- Recently my phone has constantly given me a error message about a uncertified thing being connected into it when nothing was connected to it! And trust me I havent been jail breacking or putting knock off stuff in it or anything like that.
- The Only thing That I have been charing with is a USB plug that I conenct into my computer to charge and it is slighty broken but manages to work.
- Lastly which is proably a main factor of the issue, water may have gone inside the phone.
Does anyone have advice on what causes the damage and if not what fees am I looking at?

Hi
The Nickys tip is not bad but I think you cannot be 100% sure about the fault if the notebook was not checked. Therefore the ASP should check the display and the FL inverter functionality and then you will get the proper answer about the fault.
But as mentioned it seems the graphic and the board are ok therefore it must be something like the FL inverter.
It would be very interesting to know what was wrong. Please post again if you have more news. Good luck

If a shortcut is used while Firefox is already open the error does not occur.

My first gen ipod mini does no longer sync with itunes 11.0. It says "cannot write or read". Ist this the end?

My first gen ipod mini (that I use in my car) does no longer sync with itunes 11.0. It basically says "cannot write or read". Is this the "end of life" of that ipod?

You mean you can't get to the Summary pane?
If you have iTunes 11 turn on the Sidebar. Go to iTunes>View and click on Show Sidebar. You can also do a Crtl+S to show the sidebar. The sidebar is where Devices appears. and Control+B to show the Menu bar
