Convert to Gray scale issue in spot color file

Hi,
I am having some problem in Acrobat X Pro on Convert to Gray Scale Preflight Fixup, but the same PDF file is working good in Acrobat 9.0 Pro for the same process.
Even I tried with the error report, but there was no error details in that report.
Please help me out to find the reason for that problem. The PDF file is having a spot color.
Please find the RGB and converted Gray image
Thanks in advance,
Veeramani.M

Kumararaja,
You can upload you file using any public/private FTP and then can embedd the link here.
Or when you click on Edit (in your message division), you get a browse option in the bottom left cornet. That allows upto 8.9MB. The way i attached!!!
BTW, what's the issue?

How convert a color PDF File to black & white (gray scale...no color)

How convert a color PDF File to black & white (gray scale...no color)??? creative cloud cs6... Acrobat etc

Hi, just wanted to add my 2¢
I've been in publishing over 25 years and live in Acrobat for making my final files. Currently with a newspaper.
This is what we do:
• Tool Panes > Print Production Window
• Select CONVERT COLORS
• Midway down under OUTPUT INTENT, check Convert Colors to Output Intent
• In the associated drop down menu, I choose (because I'm printing on newsprint) DOT GAIN 20% – If you're working on better stock, choose a lower dot gain percentage.
• Click OK – this will convert the file
• Save
Note: this affects the file you're working with. Make sure that you use this method on a COPY if you want to retain the original color version.
I think if you compare my method to the Preflight method, you'll see a tighter contrast and better blacks. I've always felt the Preflight method left continuous tones a little muddy.
Now if there was only a way to add that to ACTIONS...!

Can aperture 3 convert a gray scale photo into a line drawing?

can aperture 3 convert a gray scale photo into a line drawing?

I have a B.F.A. degree in painting which educated me in the "history of art" with appreciation of the old masters. I agree with your statement that, "anyone mistaking photos converted to "line drawings, watercolors,or paintings" is simply ignorant" and that, "line art is to drawing what clip art is to painting."
I appreciate your passion and love for keeping "visual creativity" true to its inherant nature. Expressing your views however, in regard to my question in this thread, is irrelevant to the question asked. I am not ignorant. My question has nothing to do with the philosophy of art. You have no idea what project I have in mind for asking my original question. I suggest that perhaps you have chosen the wrong forum to express your views. Sticking to the question asked, as the other participants have, has been most helpful to me and I appreciate their response.
Thanks for your attention.

How to Convert FLIR Gray Scale Image to a Temperature Map in NI VBAI

I have been working with a FLIR A315 Infra-Red camera and NI's VBAI software. I need to determine the presence and continuity of a hot mastic foam that has been injected into the hollow bulb of a rubber weatherstrip seal in 4 adjacent locations that flow together inside the weatherstrip bulb to form a continuous foamed mastic plug.
So far, I have been able to trigger image acquistions in VBAI from a FLIR IR camera by monitoring an Allen-Bradley PLC's status bit. The communication with the FLIR A315 camera is via the IMAQdx GigE driver. However, I haven't figured out how to detemine the temperatures from the gray scale images I receive from the FLIR camera. I wonder if someone could give me some pointers on how to do this.
I have attached some images below to illustrate what I am working with and how far I've gotten.
iPhone_Photo.jpg - shows a photograph of the weatherstrip section that the FLIR IR camera is "looking" at.
FLIR_IR_Monitor.jpg - a screen capture of a FLIR IR monitor utility that shows temperatures measured at a number of points and areas (showing it can be done)
NI_VBAI.jpg - part of my VBAI 2010 project which shows the image I've acquired from the FLIR A315 IR Camera
So, I am part of the way there, but so far have not found a way to map the gray scale image that VBAI is acquiring from the FLIR IR camera into a heat map from which I can determine temperatures - and would appreciate some help on how to do this.
Kind regards,
Nick

Hello,
Image provided by FLIR camera are unsigned 16bit.
Depending on the FLIR temperature scale you selected (10mK or 100mK), you will have to divide by a 10 or 100 factor to get K values. Don't select radiometric output.
So if your object is cold, the population of the histogram of your image will be on the left part of it and if the object is hot, the population of the histogram will be on the right part.
If you want your temperature values in Celcius, just add 273,15 to the Kelvin Value.
Then you can add a color palette in VBAI (FLIR iron is available)
Hope this helps

Convert PDF Document to PDF with Spot Color

I want to convert a regular PDF document with RGB/CMYK color profile to one with Spot color. Can this be done using Acrobat X Pro, if so How?

Hi Steve
I am still working on the process to automate the conversion of PDF file with RGB color profile to Spot.
I am nearly there, here is the method...
1. Have a prefight profile with the spot color fixes. For now I put in 10 colors.
2. Wrote a Javascript that will invoke the preflight profile
3. Cretated an application (AutoSpotFix) in VC++ and Acrobat SDK that will open the document and assign the javascript function to 'WillSave' document action. The AutoSpotFix will then trigger the save on the document.
Java script had to be involved because SDK cannot invoke the preflight profile.
Now my problem is the document can contain any spot color, I need to
a) Either put in the thousands of spot color into my preflight profile, which will take days to do. Or I can create a preflight profile file (*.kfp) and load it, which is an XML file.
b) Dynamically load the preflight profile file with the few current colors, for which I need to dynamically create the preflifgt profile.
Either way I have to create the *.kfp file, Is there a way to create the Preflight profile file?

Hp Officejet 8000 Set to print Gray scale but still using color

Hp Officejet 8000 Set to print Gray scale and use only Black ink, Draft Quality, but still using color ink. I'm replacing color ink cart more often the Black. I understand even when set to black only it will still use some color in cleaning and such. but not the amount of color it is using now. Printer has me pissed total waste of money. I'm ready to get my Xerox Phaser solid ink printer fixed. as it was super cheap on ink.

Hello Lynn,
Is your network router located near your desktop PC and L7590 officejet?
If so, I would suggest that you connect the L7590 to the router with an ethernet cable(you can also leave your usb cable connected to the desktop). Then you can connect more directly (still through the network) to the L7590 with your dv7 laptop instead of connecting through the desktop. Since your dv7 is wirelessly connected to the router, and the L7590 is also connected (wired) to the same router, the setup is much easier.
If you want to try this, first download the software from hp.com (click here for the download page). When you run the installation on your dv7 notebook you will be guided through the steps necessary for connecting to the printer via the network.
Dont forget to reply and let us know how it goes!

How can I rasterize a spot color file without creating "border" pixels between areas that are adjacent to each other but should not be overlapping?

We use Illustrator to create circuit layouts. For part of our process, we create an image of all of the layers using spot colors to show the printed layers overlapping each other. We then rasterize the file and send the image through a Matlab routine that performs some analysis of the circuits based on the colors of the pixels.
In some cases, I have created images with areas next to each other, but not overlapping. When rasterizing the image, the rasterizing process appears to treat the borders as overlapping and creates a single pixel wide border between the 2 areas when there is none. This is playing havoc with our Matlab routine.
I can manually go in and remove the rasterized border, however on some projects, this is a very lengthy process. Has anyone experienced anything like this, or have any ideas on how to prevent this?

PDF showing in gray scale when it is color in other readers

I have created a stack of PFD files from sets JPG or TIF images. An example can be seen at http://www.awm.gov.au/collection/records/awm78/1/awm78-1-6.pdf
When we open these with Acrobat Reader 10.0.0 the pages are in grey scale. When opened with any other non Adobe reader (eg FoxIt) they are in full color.
Please help! What is different.

Thanks Michael. I'm a bit confused. How doe the one file have different color spaces? And how can this be identified?

How to convert color image(24 bit) YUV 4:2:2 to gray scale 8 bit image

I am using sony DFW-X700 color camera for one of vision applications.Does NI Compact Vision System(CVS) support YUV 4:2:2 format(8 bit each).I want to do gray scale processing, so i need to convert the YUV color into gray scale (8-bit) in the software(like Labview). Please suggest us how to do this conversion for better gray scale image clarity from color.

In YUV color space, Y represents the gray scale; in RGB color space, R=G=B represents gray scale. You can simply set R=G=B=Y, to convert YUV to RGB. If the original color depth is 24 bit, then the result is 24 bit too.
You can create gray scale color table like this:
array size = 256;
[0] = 0x000000;
[1] = 0x010101;
[2] = 0x020202;
[255] = 0xFFFFFF;
To convert 24 bit gray scale to 8 bit, check every pixel in 24 bit image to find the array index according to the color table, and replace the pixel with array index.

Converting Gray Scale to RGB

Can anybody tell me how to convert a Gray Scale image to RGB image?
I have written a Code:
public BufferedImage convertToRGB(BufferedImage input){
ColorSpace RGBSpace = ColorSpace.getInstance (ColorSpace.CS_LINEAR_RGB);
ColorConvertOp rgbConvert = new ColorConvertOp (RGBSpace, null);
BufferedImage output = new BufferedImage (input.getWidth(), input.getHeight(), BufferedImage.TYPE_INT_ARGB);
return rgbConvert.filter (input, output);
But this doesn't seem to work.
please help me
thanx

Try this:
public BufferedImage convertToRGB(BufferedImage input)
ColorSpace RGBSpace = ColorSpace.getInstance(ColorSpace.CS_sRGB);
ColorConvertOp rgbConvert = new ColorConvertOp(RGBSpace, null);
output = rgbConvert.filter(input, null);
return output;
}

How to convert the graph to gray scale

Hi
I am using MS 1.1 version, I need to take the print of the graphs which is provided by NI. The problem here is that i need the GUI to show the graph in multicolor environment, but when i am going to print it on a paper, i should be able to convert into gray scale. Can you kindly suggest me what should be done to achieve this?
Is there any features which present in MS which can help an user to decide this conversion at run time.
Thanks & Regards
Sandy

Hi Sandy,
I hope you are doing well today! What is MS? You should be able to use the invoke nodes of the graph controls to export an image and do some manipulations to it. Can you be more specific as to what you want to do and what kind of programs you are going to use?

Help converting to 2 spot colors

Hello All,
I am ashamed to say I am a teacher in a vocational high school that doesn't know much about
computer programs. I am an old camera/stripper person. I have been teaching 24 years and am well
versed in PageMaker, In=Design and Photoshop.
What I am trying to do is the following.
I am trying to convert a vector image into 2 spot colors.
For example: I have a wreath and bow    I would like to print the wreath in a
PMS 348 and the bow in 185 Red.
I can of course do this with process colors, but often the job does not warrant
using process so I would like to be able to print using solid PMS colors.
I think that is it in a nutshell. I have tried to work in Photoshop but have had no luck.
My questions are:
1. - I am using a Vector image from an artbook CD. - Is this good?
2. - Can I convert a picture downloaded from the internet?
3. - How can i learn to do this? - I have looked for online help and the school will not pay
for me to take a course.
Lastly, I understand layers well but have little to no knowledge of Channels
I sure would like to be able to show the students how to do this. Does anyone know how to do this
or where I can view tutorial on this matter.
I sure would appreciate any help.   Thanks   Print Dad

You don’t say what version of Illustrator, but regardless if you already have vector art I’d stay away from converting a rasterized image to vector. There are relatively easy ways of doing what you want with a vector image with the merge swatch feature, but that depends on what sort of vector image you have. Presumably the vector wreath you are working with is made up of a number of rgb or cmyk values.
1         OK, so you are starting with a vector image, that’s a good start. Are you positive it is vector? In Illustrator can you see all the points when you select the object, and not just one big square?
2         You could convert a picture from the internet, but that would not work nearly as well.
3 See below:
Delete all the swatches from you pallet. Drag a 185 & 348 swatch from the pantone pallet to your swatch pallet.
Set the Magic Wand to a useful value (double click on the wand to bring up the dialog box). The lower the value the more work you’ll have to do, but you’ll wind up with more shades of red and green).
Click on the most saturated area of red with the Magic Wand Tool. Click on your 185 red swatch. Hide the newly minted resulting 185 red (Ctrl-3).
Click on the next most saturated area of red with the Magic Want Tool. Click on your 185 red swatch. On your color pallet, reduce the pantone 185 red to less than 100% to taste. Hide the result with the Ctrl-3 command again.
Keep going until there is no red remaining visible, and then do the same with the green.
When you can see no more remaining parts of the wreath, you should be almost there. Just to be sure, do Ctrl-A and make sure nothing gets selected (for instance white objects) when you do so. If nothing gets selected, you should have only the items you have colored. Use the command Ctrl-Alt-3 to reveal all the items you have hid. (The hide and unhide are under the OBJECT menu, but the shortcuts are a bit quicker). If you do have white objects, you can still use the pantone red/green and set the color percentage to 0%.
Select the print command and print to a postscript device. (A .pdf output will work if you are not hooked up to a postscript printer). In the resulting print dialog box click on the “Output” command in the upper left corner. Under the Mode select “Separations” Hopefully if all went well, under the Document Ink Colors only 185 Red and 348 Green will have a little printer icon next to them.
No need to concern yourself with channels.

PSD Spot Color Channels in Illustrator CS4

Hi all.
Screenprinter here. Trying to migrate my way into CS4. No such
luck so far.
Way back in Illustrator CS2 I used to be able to place a PSD file with Spot Channels,
and have each channel show up as a separate object in Illustrator. This was incredibly
useful, nay, necessary for creating/laying out separations and adding vector work.
From what I've read and tried, this is no longer possible in CS4, which leaves me running two versions,
which is no fun.
I suppose my question is, has anyone come up with a workaround for this, or does the newest
release support this type of operation? From reading the boards, I've found that I'm not nearly
the only person who needs this feature, and so would hope that there is an alternative to
running CS2 still.
Us poor lowly screen printers get dumped on by nearly all Adobe products in terms of usability
(ever shoot the stock reg marks from photoshop?) give us this one feature!

In Illustrator CS2, the individual Spot Channels from Photoshop used to become Opacity masks when imported.
In Illustrator CS4, they are not converted to Opacity masks. Your spot colors are still there - look in the Swatches panel. There is a Spot channels image in the layers panel with 100% Multiply blend mode applied to it.
So it is not correct to say that it is no longer possible to bring spot channels from Photoshop into the Illustrator CS4. See the comparison snapshots below.
Hope this helps.

How to print a downloaded color document in black or gray scale

I have Adobe Reader 9; Windows Vista Home Premium; HP Officejet Pro 8000 Wireless printer. I have downloaded a document that is pre-set to print in color. I want to print it in black or gray scale. I click on the printer icon for the printing pop up. When I click on the Properties bar to make the request for black or gray scale, nothing happens. What steps can I take to convert the pre-set color download to be printed in black or gray scale? Thanks!

I have only had the experience when I have downloaded a link from within an email to my Hotmail account when the download has already been set up in color. To date, I have not had that problem with Word. There are specifically two situations regarding two different monthly emailed newsletters. This is through Internet Explorer 8; Windows Vista Home Premium. (I will not use Internet Explorer 9. It causes blocks for routine procedures, especially involving my Hotmail account--such as not being able initially to download a normal attachment or, if downloaded, not being able to print a normal download attachment.) However, after I sent out my request for help, I switched to Mozilla Firefox and was able to print the "color" download in black right away because the Preferences bar responded as it should. (Through Internet Explorer 8, regarding this particular link/download/attachment, the printing pop up had a Properties bar. However, I am aware that, in some other pop up formats, there are both a Properties bar and a Preferences bar to choose from.) I have Mozilla Firefox as a backup because, sometimes, I have to resort to it to download email attachments (whether black or color) coming from the east coast when they will not download through Internet Explorer 8. (I am near the geographic center of the US.) Thank you for your interest in my concern. I will gladly accept any advice regarding being able to print an email attachment/link color download in black when using Internet Explorer 8! Does it depend on how the link attachment is set up or what the link attachment is??

Converting CYMK to spot color?

Alright, i just read the 'how to get help quickly', and will attempt to not let my panic show through too much:
I designed graphics to go into my college's literary magazine. I used only two colors: brown and green (8dc63f and 603913). However, last week he informed us (the magazine production people) that RGB wasn't acceptable, since he was going to print in something called 'spot color'. Never heard of it before, but after reasearching, I think I have a vague grasp on it: basically instead of CYMK printing process, he's just going to have two plates, one with each color, and stamp them on the pages (like screen printing). That's fine, but I don't understand how it relates to my files. So we sent the psd files to the printer's "photoshop specialist" and then yesterday I was informed that there was no way to seperate the colors into pantone plates, and that either the book was now going to be blank (thankfully the cover is going to be printed seperately in CYMK so that's fine), or we could use clipart (!!thanks for discrediting a semester of my work), or I could learn to use illustrator and redesign the whole book by monday.
I panic, obviuosly, because after downloading the trial version of illustrator I realized that it's actually nothing like working in photoshop (where's my tablet sensitivity? this is NOTHING like 'illustrating'), and at the end of last night's terror, this is all i could produce: http://img576.imageshack.us/img576/2993/illustrator.jpg
Now for reference, the image I originally made in photoshop looks like this (when placed on a brown background to simulate paper): http://img829.imageshack.us/img829/7015/photoshopf.jpg
I am very confused, because I don't understand why the printing company can seperate the illustrator file into two color plates, but not the photoshop file. Both use the same colors (Pantone 375 and Pantone 161 C, I've learned). I have no clue how to save ANYTHING in 'spot format', the only difference between photoshop and illustrator is that I can click on the pantone swatch in illustrator.
Obviously I'm ignorant and confused, and I appologise for that, since it only makes this situation worse (who knows if I'm using the right terminology).
tl;dr:
I have a whole bunch of psd files that need to be converted to something called 'spot color format'
the images are graphics to be placed in an indesign file, not to be printed on their own, so really, they have to be in the spot color format.
Is there any way in reality to maintain the quality of these images and convert them into 'spot color format'?
I'm still trying to understand illustrator (I'm really a painter, not a designer -- wtf is a vector), but would love to convert the psd files I already have into something usable. the printer people didn't know how, I don't know how (or even understand the issue), but maybe you will?

I tried this with the image you posted, so I can describe in detail the steps.
From the image menu choose Duplicate to keep the original for reference.
From the Image menu choose Mode > CMYK Color.
In the Channels palette, delete (by dragging to the trash there) all channels except the Yellow and Black channels.
Double click the icon of the Black channel and in the window that opens click on the color swatch, then in the next window that opens click the Color Libraries button, and when the next window opens type quickly on your keyboard 161, make sure the desired color is picked and press OK on this and previous window to apply.
Repeat the same for the Yellow channel but choose 375.
Select the 161 channel (former Black) and press Ctrl + L to open Levels. Drag the middle arrow of Input Levels referring to the original to get similar darkness (to me around 0.30 looks similar shade). Press OK to apply and close.
Hold Ctrl and click on the icon of the 375 (former Yellow) channel to load its shading as a selection, and press Ctrl + Shift + I to invert the selection.
Make sure the 161 (former Black) channel is selected and press Ctrl + L to open Levels again. Move the right (white) arrow of the Output Levels (at the bottom) until the background matches in brightness the background of the original (to me 150 looks similar).
That's basically it based on my quick try with your image. This example should help you understand the basic idea and from there if you like, you can further play with the image if you feel you can make it any better with these two colors.
Regarding Spot colors, the idea is that a printing press uses 4 color plates (in Photoshop represented as the four CMYK channels when the image is in CMYK color mode) to print all possible process colors by mixing these four colors (inks). Spot colors are pure inks in cans and each spot color (ink) requires its own plate. Sometimes people print 4 process color plus an additional spot color for achieving a special effect like gold ink or pure corporate color to ensure color consistency which may not be as good when using the four colors mix. But very often, spot colors are used for printing with less than 4 plates to save money and sometimes for artistic effect with special inks.
Following the above example converts the CMYK document to Multichannel Color mode and you have only a few file formats available for saving in the Save As options. From these, practical ones are DCS and PSD files. Both are OK for printing but you may want to confirm with your printer. However if you want to place Multichannel image in programs like Illustrator or inDesign you have to use DCS.
