Illustrator :: How To Change Color To Rich Black By Manually Entering CMYK Values
Jan 18, 2014
I've had this problem before, and it randomly popped up again today.
This time restarting Ai fixed the issue the first time. I just don't know if this was human-error/setting on my end, or a minor bug to report.
So I create a CMYK Ai doc. Create some black text and/or shapes. Then decide to change color to rich black by manually entering CMYK values (in this case, 60, 40, 40, 90), select ok. However, the colors revert back to original percentages (75, 68, 67, 90).
In past versions, it's happened once or twice, and restarting Ai didn't solve the first time.
My problem is that I am converting RGB native images to CMYK and my Key (Black) comes out rich, contains equal levels of CMY and K, instead of true black, only k.
Currently my way around this is to do the standard convert to profile CMYK and with my path selected to the section I would like to be true black simply turn off all CM and Y channels and re-save the image but this is a little labor intensive.
Is there a way that I can go straight from RGB to CMYK and achieve true black without alteration?
I'm working in Photoshop CS 5.5 on a Mac, and I want to apply a specific CMYK color to a selection in an image. I create the color with the values C=0, M=100, Y=100, K=10 and add it to my color swatches. Then I select the section of the image where I want to apply the new color and fill it with the paint bucket. The color fills the section just fine and life is good. But then when I roll over the section with the eyedropper to double-check the CMYK values in the Info window, it shows that they've inexplicably shifted to C=9, M=100, Y=100, K=1.
I am having a bumper sticker printed in mass quantities. The sticker is black with with large white text. My problem started when I exported my ai file to a PDF and the black came out gray. I then exported as a jpeg and found the same grey result. After searching online I found that pure black is not 100K, and it seems to be a mixture of all the CMYK colors. Well I adjusted the colors to make a rich black blend and when I saved it as a jpeg the black displayed as intended. However when i exported the same ai file as a PDF the black still looks grey. Will the pdf print pure black even though it doesnt display that way on screen?
Art brushes are showing a grey version of what should be a Rich Black RGB 0, 0, 0,. Furthermore, expanding the art brush stroke and sampling the color shows the strokes "Black" is actually: 32,32,32, pre-expansion the RGB sample shows the stroke is 0,0,0.
Color Mode=RGB Print Proof=NO Document =RGB Display all Blacks, print all Blacks=Rich Black
Options for Art Brush show art brush swatch is Rich Black but using eyedropper (within brush options window) and sampling preview stroke CHANGES swatch preview from Rich Black to Grey.
When I make my text red (standard CMYK red) on a black background, it looks rasterized. (See image below)
I tried using different standard fonts, but result is the same. Aslo when I export it for high quality printing, the resulting pdf document also show the red text somewhat rasterized. (Does not appear smooth red).
I have a file from a client that has a table with the color values recorded as CMYK. (e.g. 50, 0, 10, 0)
I'd like to display the colors but I can only figure out how to do it if it's in the 256 color format. Is there a way for me to convert CMYK color values to a 256 color value. I realize the hues/colors won't be perfect, and I'll be happy with colors close to what the original data was using. Maybe there's a way to go from CMYK to RGB, and then to 246?
I have a photo of an object on a black background, and during the editing process the cmyk values of the black background are c=75 m=68 y=67 k=90. As this image is to be placed on a business card, if it is possible to change the values to 100% K or 40% C 100 %.
Is there a way to export a document @ a different resolution than 72DPI? I know I can set the horizontal/vertical scale to save it at a larger dimension at 72DPI, but I need the file to be actual size and 300DPI.
This is part of a larger process, and I'd prefer to do the entire process from Illustrator, and not have to open the files in Photoshop to change the size/resolution.
Also, is it possible to change the color mode to CMYK or Greyscale for the exported Jpeg?
Somehow I've turned off the color selection so that I don't have a color when I select a part of a drawing on a layer. The drawing area stays black whether I have selected it or not and I don't know how to turn back on the color.
how I can turn on the color again so that when I select a line it changes from black to red or magenta or whatever?
I want a script that can convert RGB value to CMYK values.
I've seen this thread which explains a script to round up and down:
[URL].....
but is there a script that i can actually define lets say the colour is yellow and in RGB it looks ok because its in RGB mode so you change it to CMYK and you have 6% - 9% cyan and you only want yellow
is there a script out there that i can say
if
cyan = 6% yellow = 80% magenta = 0% black = 0%
then change to
cyan = 0% yellow = 80& mangenta = 0% black = 0%
I don't mind writting the code for each colour that needs to be converted as it would only need defining once but how would i make this script?
When I use a Pantone color in CS5 and then convert to process, I get certain values for CMYK. However, when I use that same Pantone color in CS6 and convert to process, I get different values for CMYK.
For example, Pantone 2685C converted to process in the both applications yields:
I am struggling to understand why Illustrator is changing the values inside the RGB and CMYK boxes. I am also not sure of the exact relationship between these vaues. Essentially, it appears that if you set the Document Color Mode to RGB, it leaves the RGB values that you type in alone. If you set the Document Color Mode to CMYK, it leaves the CMYK values alone.
But as soon as you change the Color Mode, it automatically modifies the values. So if you were in RGB mode and you set some RGB values, it changes those RGB values when you switch to CMYK mode. And vice versa.
I had thought that the CMYK palette was a subset of the RGB palette. It would make sense to me if it did this when I switched from RGB to CMYK mode, but it doesn't make sense to me why it does this when I switch from CMYK to RGB mode.
The other thing I am confused about is the relationship of the values in the RGB boxes to the values in the CMYK boxes. I would have thought that the relationship between them would be static. Actually, it is not. When I am in CMYK mode and I enter a CMYK value of 90 16 0 0, the RGB values become 0 158 222. But when I switch over to RGB mode, the RGB values of 0 158 222 result in CMYK values of 75 23 0 0.
I made a simple poster using photoshop to make the background and illustrator to make the fonts and some other stuff. In CMYK my black is just 100% K ( in photoshop)
When placing image in illustrator the 100% K (black) changes to different black with C M Y added. But then when I save it as PDF the preview shows black as a bit grey (which is something normal- in print it will be just black). So my question is .. should I change enything just to be able to see a 100% K in illustrator in order to match CMYK values of Photoshop? Or should I leave it this way? I guess if I am getting a "grey" in PDF preview is something good isn'it? because in photoshop when I set to 100%K in my screeen it looks like grey and not total black.
Alright, I have a grunge vector I'm using in an opacity mask over my shapes. I need to convert my .eps grunge vector to full black, if I dont then the end result looks fine in illustrator...but when brought into PS you can still see light pieces of the object that the grunge was supposed to mask out.
When I click the eps file and use %100 black: instead of filling the grunge bits to black, it fills the entire selection black so I end up with a big black box, and if I use the stroke, it outlines the box itself. I tried making a compound path and also expanding the grunge, then retrying but no dice. Does AI recognize this eps file as one big square selection?
How do I get my .eps grunge vector %100 black rather than the CMYK black?
win xp CS2 We have tif files of drawings placed in a ID publication. Our printer has informed me that the drawings, which are basic line drawing wtih a color panel behind, are constructed of 100% of all four colors and therefore too much ink for the press to handle. The printer wants the black converted to a rich blk (40, 20, 10, 100)Is there a easy clean way of doing this? I suspect it's something in the channel pallette. Your thoughts?
A client has asked a question that seems strange to me regarding rich blacks in images. They want to be able to change blacks in an image that might be 80 80 80 100 to 30 30 30 100. My thought would be that they would just change the ink limit to what the printer has recommended. They could also reduce the black value in curves, but to get their limits would look strange. Before I go back and state my opinion, I would love to hear from some printers to see if they have any other opinions. They are not trying to mix colours to put them into InDesign.
Is there anyway to convert 0/0/0/100 Black to PMS Black by replacing the cmyk swatch with the PMS swatch? I have a bunch of Illy packaging files that are using CMYK black that need to be changed to Pantone Black C and the only way it seems that I can do it is by selecting same fill and/or stroke. I tried using recolor artwork, but cant get that to work with cmyk black either.
I need to insert a table on one of my Inventor drawings, however, it will vary in size (Fixed colums, variable number of rows). I have searched the forum and found this snippet of code to add a 2x20 table.
Sub Main()Dim oDrawDoc As DrawingDocumentoDrawDoc = ThisApplication.ActiveDocumentDim oSheet As SheetoSheet = oDrawDoc.ActiveSheet' Set the column titlesDim oTitles() As String = {"Member","Pos. From Datum A"}Dim oPoint As Point2doPoint = ThisApplication.TransientGeometry.CreatePoint2d(1, 28.7)' Create the custom tableDim oCustomTable As CustomTableoCustomTable = oSheet.CustomTables.Add("Infill Spacing", oPoint, 2, 20, oTitles)End Sub
The Problem
I now need to be able to do two things:
1. Delete all custom tables that may be on the drawing ( I may have more than 1 custom table on the drawing)
2. Access the individual rows and colums in a specific table so I can write a variable into them.
I have searched high and low for the API commands, but cant seem to find them.
I have one problem in ilogic i developed the model using ilogic rules and dimension values updated through the User interface form.
problem is while entering the values in UI, model updates automatically, but I want to stop automatic update and after entering the all the parameters in the UI then click the done button only update the model.
I make a shape filled with an 80% black from the CMYK palette (0,0,0,80), and another shape filled with 80% black from the grayscale palette. Then i convert the color space from CMYK to RGB and the two grays that were identical in CMYK appear very different in RGB. Why is this?
