Texture filter in Rgb mode to cmyk - safe for print job?

I want to apply the texture filter to a photo for a print job but the texture filter only works in rgb. Can the rgb file be SAFELY converted to cmyk for print?

In what way do you think a conversion from RGB to CMYK after the application of the filter will not be safe? What do you expect to go wrong?
...or if you have tried it, what has gone wrong?

  • CMYK Profile for Printing

    Hi
    I have just migrated from CS3 to CS4 Extended. And now when I convert my image from RGB to CYMK, I am asked to set up a profile. I use photoshop for press printing. Which default CYMK profile I should go for?
    Thanx
    Max

    OK. First, Rick McCleary's advice was good, best case scenario is to have a custom ICC profile describing your precise print conditions (your in-house press, the print standard, the inks, stock).
    If you don't have such a profile you can use others. The three Rick mentioned describe various print conditions on coated paper. Each has a specified total ink limit which is an important consideration. To check this, make a blank CMYK document. Assign the profile. Hit "D". Click on the foreground black color and add the CMYK numbers
    Japan newspaper has a TIL of 240. The profile describes an average newspaper print condition in Japan.
    US Web Coated SWOP has TIL of 300, with black ink limit of 90. It describes US Web Press printing to SWOP standard on a coated sheet. The two Web profiles Rick McCleary specified have TIL of 307 and 300, with black ink limits of 97 and 98.
    TIL needs to be less for uncoated stock. It can't accept as much ink. As the paper stacks up at the delivery end, if there is too much ink it can offset on the back side of the sheet. This is especially likely to happen with a large image with lots of shadow area.
    Since you mentioned US Web Coated SWOP and Japan Newspaper, perhaps you've been using them in CS3. If so, and your press runs have been consistent and reliable, you could also use the same profiles in CS4.

  • Question about preparing CMYK colours for print

    hey guys, Im preparing some artwork in CMYK to go on a CD cover
    on the printers site they say that if you have up to 400% colour (so 100% in C,M,Y, and K) it can get too thick and start cracking and falling off.
    "We recommend that you stick to a total of 230% wherever possible for any colour (i.e. the combined % of C, M, Y, and K add up to less than 230%)."
    now I notice in my image the black areas are indeed up to 400% ink, is there a way I can reduce the colours correctly so nothing goes over 230%, without losing my lighter colours or blacks? thankyou

    But black ink by it self should suffice.
    Mainly for text and cartain graphic elements, in my opinion, or in completely b&w compositions.
    Additionally it might cause registration issues when black objects overlap colored elements.
    Spaciousmind, please provide a screenshot or lores of your layout, so that we can provide relevant advice.
    And how did you arrive at 400% Total Area Coverage (TAC) in the first place?
    Basically I would recommend
    • to edit photographic and painterly images in their original RGB-spaces (which can be contained as Smart Objects in CMYK-files) and
    • create only graphical and text elements in the seprataed CMYK-file.
    230% TAC seems very low, as for example newspaper print requires that low a number (and probably some other processes that are not offset-print).
    Please ask your printer to specify their CMYK-space by way of an ICC-profile.
    Edit: By the way, even if the printer should provide an ICC-profile simply converting your CMYK-file to that will probably not be the best way to go.

  • Converting RGB PDF to CMYK PDF

    I'm looking for a way to convert RGB PDF's to CMYK PDF for printing purposes. The RGB PDF is created by an online Flash application and I'm hoping to convert the file using Acrobat via Command line. I have tried a couple of programs e.g. PStill and PDFcreator but these just don't do the job. It's important to use the command line due to the fact that the conversion must be done automatically on a dedicated server.
    Important to know is that the PDF consists of texts and images and gradients. This is a RGB example which I would like to convert. This is the CMYK output I have created manually.
    Other solutions next to Acrobat are also welcome as long as they do the job

    In your original message you say "the conversion must be done automatically on a dedicated server" - this implies that Acrobat is being used outside the EULA, which strictly forbids installation as a server process. Acrobat is licensed for individual interactive desktop use by one person, no other deployments are allowed.
    You cannot access Acrobat's editing and batch-processing functions from the commandline at all. Adobe has server-based solutions for PDF generation  (LiveCycle ES3) but they are extremely expensive and would need work to get them to do what you're looking for. Realistically, your Flash developer needs to recode his app to output in CMYK or you will need third-party software on the server to re-fry the files. I don't know of any off-the-shelf commandline tools which can perform color conversion on existing PDFs.

  • RGB Logo uses Overlay transparency... need in CMYK for print but color changes in overlay

    I am working with a logo someone else created in RGB using the Overlay transparency. When I convert it to CMYK just one area seems to "change color".
    I tried inserting both versions here - but it isn't working too well. Basically, in the image below the outline of the "scales" appears darker in the CMYK version for printing. Any ideas on how I can adjust it to print in the same vibrant color the RGB is showing?

    fill in info RGB is light (like on your screen) and adds more light when mixed, CMYK are pigments and adds more color or multiplies, when mixed

  • Illustrator CS6 color mode default CMYK opening CS5 files as RGB

    Hi.
    Having a bit of trouble as Illustrator CS6 (that I've set to a default color mode of CMYK) is opening CS5 CMYK files as RGB color profile. I don't get a choice. And so it is messing with my color palettes when I convert back to a CMYK color profile.
    Can anyone help? I can't find any answers when I search.
    Any assistance appreciated. It's potentially going to kill a lot of time if I can't fix this.
    Thanks

    Hi Rachel,
    You can not set a default color mode to make Illustrator open all files in a certain color mode. A file opens in the mode it was saved.
    What makes you think that the CS5 files that open as RGB were CMYK and not RGB?

  • RGB to CMYK to commercial printer

    We are using CS2 InDesign and Photoshop 7 on a PC. I am putting together two
    large books. One insert section of the first book has color photos. I have
    to prepare these color photos for a printer located in China. They want all
    images to be CMYK .tiff.
    I have an assortment of about 100 images from various sources around the
    world, there are .tif, .jpg. .bmp, and .psd. All of them appear to be RGB.
    There are images with: 1) no color profile, 2) sRGB IE60966-2.1, and Adobe
    RGB 1998. Do all images need to have the same RGB color profile before
    converting to CMYK?
    I have been converting all of these to .tif (and using a single dpi/pixel
    resolution for
    all images).
    Do I just select/save as color mode CMYK? Or are there special
    settings/profiles I need to know about. Is there anything special for China?
    The printer's English is not that clear . I was hoping that someone in this
    group would be familiar with RGB to CMYK conversion.
    Also, it appears that the final PDF pages (with embedded Tiff images) will
    be very large. The first complete book for this project (there are two
    books) looks like it will be about 20GB. The second book looks like it could
    be 12GB. Both books together equal about 1,000 pages and have about 1,000
    images. 90% of the images are grayscale. What are the current technologies
    for sending large projects like this to a printer?
    Thanks
    ps, the Photoshop group suggested that I write to this group.

    Tech....
    In the conversions, are you referring to conversions of B&W or color images? I'll assume color for the moment.
    Assuming your monitor is properly calibrated, and assuming you are viewing your color images on your monitor, your conversions should keep "in gamut" colors the same. You will, however, probably see some loss of dynamic range, color, and saturation as you enter CMYK. If the color and dynamic range of the original is all within the destination CMYK gamut, you should see very little, if any, shift. The sad fact is that CMYK on press has limited dynamic range and color, especially compared to a bright monitor. This is generally true, though CMYK can print some colors that lie outside the typical monitor's gamut.
    If you have a brightly colored original in RGB mode, then you should experiment with both perceptual and relative colorimetric rendering to see which one looks best. This is an image by image thing. Relative colorimetric will reproduce all "in gamut colors" as accurately as possible, then will take out of gamut colors and bring them to the closest printable color. This can cause loss of detail and 'piling up of colors' as you near the boundaries of the image's color gamut in the destination CMYK space. Perceptual scales ALL colors and preserves the relationships between colors, which sacrifices color accuracy and saturation, but sometimes looks more natural, especially if there are a LOT of out of gamut colors. Pick whichever ones looks best overall.
    Then, once in CMYK, make minor curves adjustments to tweak if for CMYK. Just be careful not to push it too far, especially in the deep shadows, since you may push beyond the ink limit of the press. For example, if you convert to US Web Coated SWOP v2, the ink limits are set at 300 total. If you drastically darken the shadow areas, you could end up with an ink limit of 320, 330, 350, etc. Knowing the ink limit of the press will help you stay within those limits. Final tweaking in CMYK is usually a good thing.
    How did you determine that the images were dull with too much magenta? Did you print a proof on a calibrated printer, or is this just your screen display? Or is this from a printed image off the press? I have a well calibrated monitor and accurate custom profiles for my inkjet. If I am sending a job to a press that supposedly prints to US Web Coated SWOP, I can proof that file on my inkjet and get a very good match. We need more information to know exactly what you are doing and how you are assessing your images.
    Normally, I do the conversion in Photoshop, using the rendering intent that looks best. Then I tweak the image in CMYK to get it looking its best. I usually have the press profile, but sometimes work with a standard profile if no custom profile is available. I leave the image tagged with my conversion profile. Then, I usually place these images into InDesign, with the profile intact (color management turned on in InDesign). I right click on the placed image to be sure that the profile and rendering intent are set to what I want. Then, I can either supply the InDesign file to the printer, or convert to PDF (leave color unchanged) and make sure that all profiles are included. InDesign should export each image to the PDF properly, along with profile and intent. I have never sent to job to press using Photoshop...only InDesign or Illustrator.
    BTW, rendering intent is only used when getting an image from one color space to another, such as a conversion from RGB to CMYK. You do that, choosing the one that looks the best. Once it is in the destination CMYK space, rendering intent is no longer needed, since all the colors and tones have already been remapped into the final space. Rendering intent is just used to help us handle those out of gamut colors.
    Hope this helps.

  • Weird bug?  Transparent background is black instead of checkerboard in RGB mode

    If I try to make a new RGB document with the Background Contents set to Transparent the canvas is filled with black instead of the checkboard pattern.  However over in the Layers window the little icon for the layer shows it as transparent with the checkerboard. In the Channels window it also appears transparent, and if I click on one of the channels which selects just one of them the canvas changes from black to the checkboard.  If I click on the RGB channel at the top the canvas changes to black again.
    Why is this happening and how do I fix it?
    If I open a new document in CMYK I get the checkerboard like I'm supposed to.
    I bought a new PC a few days ago and this is a fresh install of Adobe CS4 on Windows 7.  Photoshop is updated to version 11.0.2.
    I could swear this wasn't happening a couple of days ago when I first installed it, and it never happened on my old XP computer. 
    edit to add: all files show a black background in RGB mode instead of the checkerboard pattern, not just when creating a new document.

    What are the Photoshop > Preferences > Transparency & Gamut > Transparency Settings?
    Boilerplate-text:
    Does turning off OpenGL in the Performance Preferences and restarting Photoshop have any bearing on the issue?
    Other than that are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?

  • RGB vs. CMYK Colorspace - Which is best to work in?

    I'm designing a document for a client, within in InDesign. Up until my last save, I've been ignoring the notice about InDesign being set in the RGB colorspace. On my last save, I changed it to the CMYK colorspace and all my linked images got lighter (some not in a good way). I understand the difference, but my question is - for sending this to print, what is the standard colorspace that most printers use? Should I be designing in the CMYK colorspace or RGB?
    Also, when I edit my photos, I switch back and forth between modes to get the best results, but what is the best mode to save them in - RGB or CMYK? I've heard conflicting answers.
    I realize that printers print in CMYK and while it would make sense to save photos and InDesign docs in CMYK, I've heard people say it's best to save in RGB. Please help. If you could also please explain your answer, just so I can gain the knowledge on this subject and understand why I'm doing what I'm doing.
    I should also mention that I'm working in CS3, but I save to a PDF from CS5.

    InDesign by default is set in the CMYK colorspace which is what most people  who use InDesign would need. The only way to set InDesign into RGB is to declare your document intent as "web" which is a bad idea for any document that you might eventually print. If you know from the get-go you will be printing your document, set InDesign to the print intent. If you are designing for the web, set it up in RGB (web intent).
    As for your images, I used to convert them to my CMYK profile early on and work that way but changed my methods a few years back as Photoshop has less editing options for CMYK images. My advice would be to keep the photo's/images in RGB until you are ready to send the document to print, then convert to your CMYK profile - IF sending to a conventional 4 color print press. If you are sending to a digital printer (including desktops), it matters less about converting to CMYK.
    Of course you could keep the images in RGB anyway and let InDesign (or the PDF export) convert them all to the same CMYK profile but you might see color shifts, as you have been experiencing. By converting them yourself in Photoshop before you send to print, you see the changes and can adjust accordingly.

  • RGB swatches in CMYK document

    hi all
    here's a conondrum:
    I am working on a document that I have set up in CMYK but, after placing an image from the web which must have been an RGB and using eyedropper to copy a colour from it, all the swatches and colours turned to RGB. Even the bits I created before placing the image and using eyedropper... and the colour scheme of the entire doc still is CMYK.
    The document is intended for print, I therefore need to change it back somehow. How do I do that please?

    Keep the document in color mode CMYK.
    Open the RGB image in photoshop, and convert to CMYK.
    Sample in Photoshop the color you need and write that down.
    Go to Illustrator and create a swatch with the color you wrote down.
    You cannot accurately sample colors from placed photos in Illustrator . Illustrator takes what is sent to the screen in RGB, and then converts that to your color mode. Do NOT use SHIFT eyedropper, though the color looks good your color will not match the CMYK values in your photo.
    Illustrator will not change your cmyk document color mode colors to RGB because you sampled with eyedropper. You most likely changed the mode of the color panel to RGB. The color panel should always match the color mode of your document, the panel is misleading otherwise.

  • Convert 2 RGB colors to CMYK in AI CS5

    Hi,
    I created a logo in RGB and now I need to have business cards printed and the file has to be in CMYK.  If I change the color mode to CMYK, the colors fade of course and don't match the RGB colors.  I only have two colors in the logo:
    #CCFFFF
    R = 204
    G = 255
    B = 255
    #0000CC
    R = 0
    B = 0
    G = 204
    The printer told me to use a CMYK color pantone guide book.  I am using AI CS5 and was able to locate the Pantone guidebooks that come with the program.  However, I am unsure which Pantone guide I am supposed to use since there are several.  What would be the best way for me to recreate the logo in CMYK mode keeping in mind that I want the two colors to match the RGB colors listed above?  I just googled CCFFFF and discovered that in CMYK it is 20,0,0,0 and # 0000CC = CMYK 100,100, 0, 20).  The color doesn't match exactly in AI, but I am assuming that this is the exact match for the printers?  Please correct me if I am wrong.
    Any assistance is greatly appreciated.
    Thanks!

    You're working backwards, typically colors would be chosen from the Pantone Spot Color guides and then converted to CMYK and finally RGB for web work.  It appears you've got a very light Blue ( 20% C ) and a very dark Purple ( 100%C, 100%M, 20%K ).  The closest Pantone to the light Blue is 628C ( 19C, 6Y ); and 662 ( 100C, 72M, 18K ) for the Purple ( these are older PMS numbers; not the "+" series ).  I'm showing you these numbers so that you'll have an idea of their relationship to Spot colors.  You have not mentioned what type of paper these cards will be printed on...coated or uncoated.  That makes a big difference, too.  Most of the time, stationery items are printed on uncoated paper using Pantone ( or other ) Spot Colors.  I often see coated, glossy business cards similar to those you would buy from VistaPrint online.  The danger is trying to match the coated paper color on a uncoated sheet in the future.  If you are planning for coated paper, the 20% and 100-100-20 combo will be OK ( although the 100C-100M-20K is a little on the dark side...almost Black ).  The dark Purple is a little troublesome because it may look good on the monitor, but you might not like the printed version ( too dark ).  If I were you I'd venture into a local print shop and ask to see their Spot Color guide for the paper you plan on using.  It's best to use your visual sense this way and then apply the CMYK equivalents in your file.  Good luck.

  • What can i do for change CMYK file for RGB file?

    what can i do for change CMYK file for RGB file, in Photoshop?
    I have to upload BEHANCE.. so please teach me, hurry.

    In Photoshop, you just change the image mode in the Image > Mode menu. Pretty basic stuff. You might want to spend some time reading some manuals to get the most of all the money you're paying.

  • Why do my custom swatches revert to RGB mode?

    Hi all,
    I'm a newbie to Illustrator. I have a few questions:
    When I create custom swatches, I choose the CYMK option in the drop down box. However, these swatches are appearing as "RGB" mode in my swatch palette. Why is that? How do I ensure my custom swatches stay in CMYK mode?
    When I later view the CMYK code for the swatches, I see that their numbers are skewed a little (for example, 34 may be 35 or 36, etc). Why is that?

    When you create a new document, make sure the color mode of the document matches with the swatch color mode. i.e if you're creating a new document in RGB and then using a CMYK swatch then the numbers will be converted to RGB. Make sure the document is also created in CMYK color mode by expanding the advaced options in new document creation dialog box.

  • Adjusting Black (K) while in RGB mode?

    Ok, so basically I'm wokring on an image in RGB mode, and I have my INFO box open, and I have the sample picker #1 and #2 set to display CMYK values.
    I'm not sure if many people realize that even if you're in RGB mode you can actually view other color information, including CMYK, within the INFO Box. If you click on the little Eye Dropper icons located within the INFO Box, it allows you to choose between different color info to be displayed, i.e. LAB, HSB, Grayscale, RGB, CMYK, etc, regardless of the color mode you're actually in.
    So I'm working on an RGB image, but I'm viewing the color info in CMYK, and my question is how do I directly adjust the K, or black, wihtin an RGB image, if I don't actually have the Black Channel available while I'm using Curves or Levels for example?
    I tried using the 'Brightness and Contrast' adjustment, but it affects everything else as well, not just the K/Black.

    I'm not really trying to affect the 'Black Channel,' I know it's confusing. In fact, technically, there is no Black Channel to speak of, because I am in fact in RGB mode.
    Basically I was just trying to increase K, Black, in the INFO Box, from 0 to 4, under the #2 sampler, without affecting CMY. Because my INFO Box, is set to read CMYK values, but I am still in RGB mode. So I'm not really trying to affect the Black Channel, I'm just trying to affect what's being read as Black, while I'm still in RGB mode.
    Right now, it's reading C=11, M=42, Y=51, K=0, and I wanted to change K to 4 without affecting the other colors, without affecting C, M and Y. 
    I just wanted to see if that was at all possible.
    I don't think using another color profile is the path I want to go down. Right now I'm just using the standard sRGB.
    I actually had to look up GCR, grey component replacement, and I don't think that's what I'm looking for either.
    I just want to make a move in Photoshop that would accomplish changing the Black readout from 0 to 4 with out affecting CMY, or at least minimally affecting CMY.
    But I guess it's not really possible at all, using the adjustments and/or the blend modes? I've tried a couple of things and nothing seems to work really.
