The Illuminant C for a printed document conversion: D65 or D50?

I have a few old color data of the 1930s which is expressed in coordinates using Illuminant C. I need to reproduce it in the swatches in a document for offset printing, I'll prepare you using InDesign. I can convert the coordinates in the LABORATORY using software. However, this requires that I replace C Illuminant D50 or D65. D65 is the match more closely to obsolete Illuminant C. But this project is intended for production printing, where it will be considered in a light booth D50. I have also been informed that the Adobe color engine also assume D50 for everything.

Are there management settings of colors that I can use to preserve the appearance of the conversion of C to D65 somehow? Or should I accept the inevitable and convert directly from C D50?

Important is the concept, either A or b:

(A) a set of tokens is observed under illuminant C and the colors are represented by XYZ or xyY.

A set XYZ sets a color absolututely, there is no need of a white point.

In this case, the calculation is simple for reason x, y, y:

z = 1-x-y

X = xY/y

Z = zY/y

X 1 = X/Xn etc.

next page 4 here:

http://docs-Hoffmann.de/cielab03022003.PDF

Xn, Yn, Zn is the D50 white point. In CIELab, it is just a reference, of course

referring to expected conditions of the printed product vision.

(B) a set of tokens is observed under illuminant C and the colors are represented by XYZ.

How would the same chips look if they were read under D50? What are the new XYZ values?

It is a question of color appearance. At the present time, I think that this is not your actual task,

Therefore, it is not said.

The CIELab values for Munsell colors are for example here, if that is important:

  • Printer: Where can I get the latest driver for my printer

    Hey everybody,

    Just got a new PC and I need the latest version of the software for my printer printer, where can I get that?

    Thank you

    Hello

    If you have an HP LaserJet printer, go to http://www.123.hp.com/Laserjet and download your software.

    For most other printers HP, go to http://123.hp.com and enter the name of your printer. For example: "HP Deskjet 3752" or "HP OfficeJet Pro 8720".

    * Do not look on the Internet for the web site of HP 123! There are many other sites not HP here try to capitalize on the name of HP. HP provides your free software... Use the links above!

    If for any reason, the 123 links do not work, you can visit the HP support site and download the software:

    1. Go to hp.com/drivers and select your language / local if necessary.
    2. Enter the name of your printer in the box under enter my HP model number.
    3. If a page appears asking you to select your exact model of the printer, select the link for your printer.
    4. On the page of software results, change the operating system to match the one you need (number 1 below)... he could already be selected.
      If an operating system is not listed, HP doesn't have any software available for your printer.
    5. Select installation software label to expand the section, if it is not already expanded, and read the name of the software (number 2).
      For Windows, if you want the complete package for your printer, you will want to download the software "Full Feature". For LaserJet, it will be called drivers and software "full." The complete package is much bigger in file size and takes up more resources, but she understands as a window of easy-to-use do things such as sweeping or check the ink and toner levels.
    6. For Windows, HP provides often a base driver package (Figure 3).
      The basic package is much smaller and is often available for several versions of Windows as a full package of features. With it, you use Windows to print and scan directly from the software you use, such as Word, Paint, photoshop, etc...
    7. Click on the download button to start the download (number 4).
    8. Read and respond to the screens that pop up to install your software.

    I hope this helps

  • My 3-in-1 uses the color cartridge for copy/printing black a black paper on the glass top...

    My 3-in-1 uses the color cartridge to black for a black document on copy/printing tray, but use black cartridge to print in black from the computer itself.

    In other words:

    (1) if I have a document with a black print in Microsoft word on my hard drive and I want to print this document in black print, while the 3-in-1 works fine. In other words, is the black cartridge can print a document in black to a black document.

    (2) if I take this same document which has just been printed in black and put one on the glass and try to produce a black document thereof using the copier function, the 3-in-1 uses the color cartridge to produce the black document... .more is very slow (the same speed it would be if I were to produce one side of color of color documents.

    Of course, it cannot be the black cartridge.

    Through a long trial and error process, I got lucky and I resolved and the resolution is not what I was expecting and makes no sense to me.

    Use the settings of the printer itself, I just changed the setting from "automatic" to the "plain" paper and the setting in 'text' value 'None '.

  • HP Start Menu and the desktop icons for HP printer Diagnostic tools

    Hello world

    I have a HP Desktop F4440 all-in-one printer and I use the Windows XP operating system. I have all the scanning software and others installed from the original HP installation disk or updates from the HP Web site for this printer. Everything works very well at the moment, but there is a small problem. The HP icon shortcuts for the Menu start-up and functions for the printer changed to a generic icon at a time given to these two places after the software installation CD was used by me to install the printer programs or desktop icon HP to utilities "Diagnostic Tools HP printer" original. It works fine otherwise, when I want to go check something on the Tools of diagnosis HP printer or HP Solution Center, but the HP icon changed to a generic at a time for a reason unknown, inexplicable. I don't have no changes to my system until the problem occurred to my knowledge other casual upgrade for the operating system or install a new windows update or HP software updates or restart the computer, but some schooner point after one of these upgrades, HP put to date or restart the HP start menu and desktop icons time replaced by a generic.

    Can someone tell me how I can recover the original HP icon and get her back Amendment? It was an icon on the web since the HP printer Diagnostics utility or function is based on the web. Is there a way I can save a copy of just the file on my computer icon so that if it goes back to that generic again once I can more easily change what it is supposed to be? I thank very you much for your help and advice.

    Hi there yoseph13,

    What has happened to me too, but after a windows update. Half the icons on my desktop have been affected. I hope that this fix works for you as well. Right-click on the icon. Go to properties. Click Change icon. Select the icon and click ok then apply and ok again. If the icon does not appear, you will need to navigate to the folder of the software and select the application.

    Good luck!

  • What is the best strategy for wireless printing?

    Hello

    I just got a HP 6500 a wireless all in one printer and have connected a cable ethernet to our wireless router. My desktop under Vista Home Premium is also connected to the router. Printing from the Desktop works fine. We also want to print wireless from a couple of Windows computer laptop, an iPhone and an iPad. I installed the driver of HP Mobile E-print on laptops and it works but I think limiting the size (5 MB) is a problem. I could not print a single page pdf, but a Word doc print very well.

    So, it looks as I could:

    R: Connect the printer to the computer by USB and share the printer on the network. Inconvenience - I think that I have to leave the office all the time and we did not have much success sharing our old HP printer.

    B: install the printer on the network via ethernet and use the built-in web server. So I guess I install the printer on every computer software?

    C: connect the printer wireless. Is this different from option B, other than do not use a cable? The printer is located near the router and the desktop computer for the cable is not a problem.

    I know it may just come down preferably individual, but I would be grateful for any advice as to what direction to go.

    Thank you.

    Dirt gardener

    A is not a good solution.  USB sharing printers printers have so many disadvantages, including some you described.  In addition, only print can be shared, not analysis or by fax.

    I like B the best.  Ethernet is superior wireless if you can connect this way - no password, without interference and is usually a faster interface.  Install the printer software on each computer (from the "Support & drivers" link at the top of this page, not a CD).

    C is OK, but only if you can not connect by Ethernet.

  • Set the zoom level for all open documents

    I work with 2,3,4,5 and 6 open documents in Photoshop CC 2015.1.1 at a time.

    What is the easiest way to create a script that gets the number of open documents and defines a specific zoom on all open documents level?

    Basic workflow

    1. select images in Bridge

    Images of BR 2 - open in Photoshop

    3 - Photoshop > > window > > mosaic all vertically

    4 - run script defined zoom level

    The script must treat all documents open that not only active in operating the scipt.

    If (! documents.length) alert (' there is no open documents.) ', ' No. 'Document');

    else {}

    var saveActiveDoc = app.activeDocument;

    for (var i = 0; i)

    app.activeDocument = documents [i];

  • What is the best way for possibly printed text?

    Hello

    I am a teacher and my exams in inDesign (because the formatting is much more reliable than Word!).

    In my reviews I leave a space for students to write by making a series of highlighted tabs the full width of the text box, then line break and repeat.

    I want to add the fixed in this sense the answer printed in OPTION. So in a single document, I can print the question on the examination, then print the answer key. I'm hoping not to have to duplicate questions in a second layer, as this then I would have to change in two places, if I need to change the question. The same would go for a layer of recovery with the answers in this document, that would depend on the same positioning two layers.

    Can anyone offer advice on how to design a document that allows the full width students to write nonprinting text AND lines on the lines that can be optionally printed.

    CS6 on OS X 10.9 using.

    Please ask if I did not provide enough detail.

    Thank you.

    I think you can do this by using conditional text. Select the responses, and then create a condition. And then you can choose to hide all text with this condition.
