• Convert RGB to CMYK and RGB image

  Hey.

  I wonder if anyone has any experience with conversion of RGB to CMYK and RGB image?

  I had a TIF in RGB, then convert to CMYK, but I thought it would be best to keep in RGB, so I converted. I read that he meant to cause losses in the data, but I don't see anything in the image, it's always very huge and 2 RGB files has the same size as well. Is there a way to compare the resolution of 2 images somehow, or how I can see what I've lost through 2 conversions?

  
  

  Thanks for help

  Data loss, you refer relates to the compromise made when appearing in RGB colors fall outside the range of available colors printing inks. In such a case, substitutions are made in the conversion of RGB to CMYK based on your choice of the Conversion Option > intent found in Edit > color settings. The good news is that if you don't see a color change when you switch from RGB to CMYK and vice versa, this means that none of the colors in RGB mode are outside of the range of CMYK ink. I suggest that intention more appropriate for the mode switches such as the one you mentioned Relative Colorimetry is the choice more practical.

  When RGB, clicking Cmd + there will show a color change if the colors are outside the range of ink. Another signal is an exclamation point beside the CMYK numbers in the info panel. To see which areas of the image are affected by the limitation of printing ink, choose View > Gamut Warning.

• I can't found the way to convert to CMYK in Photoshop element 14

  Hello!

  I have Photoshop elements 14 and I would like to convert a CMYK image (to keep the colors of the coil in the printing industry).

  I have only the following modes

  I have photo /Mode/ and I found these choices:

  Bitmap or grayscale or indexed color or RGB colors and only in 8-bit levels.

  How could I do?

  Thanks for replying to me.

  You do not, because he was never present in the elements, only in Photoshop.

  And you're wrong, CMYK (CMYK) is only required for offset professional or similar, in this case, only the printer can provide an accurate conversion for its inks and papers.

  The CMYK mode is much more limited in color that the RGB mode used by your camera and display. Your printer at home and print more online services require RGB (sRGB or aRGVB) for very good reasons.

• Certified PDF with RGB image. Bug?

  Hello

  We have a problem with a certain document created in InDesign CS5 on some Snow Leopard machines. It is a brochure in color, with an RGB image placed by mistake. We then print to a .ps file we then place into a control on a Pitstop server folder. This server checks and returns a certified PDF file.

  The problem is that he actually approves images RGB for the CPC, worse still it converts them to CMYK without warning. When we create the .ps on some other Mac file, Pitstop control fails on the RGB image.

  So I think that we have ruled out a problem with Pitstop server. What can cause this? A setting in InDesign? A bug in the operating system?

  Anyone?

  InDesign doesn't convert not the RGB images, that may have mistakenly been flying over in a document, an output of. PS.

  I guess you set output > color to Composite leave unchanged?

  Export to PDF/X-4 produces a not flattened PDF to no color conversion and all embedded profiles.

• I noticed that some jpeg (RGB) images are not display in Internet Explorer 11, but they present very well in other browsers. In addition, the images used to display properly in Internet Explorer. No idea what is happening?

  I noticed that some jpeg images are not display in Internet Explorer 11, but they display well in other browsers. I checked they are RGB images, because apparently some people accidentally use the CMYK format. IE is configured to display the images - I checked that also. The images used to display properly in Internet Explorer, and the images have not been changed on the server. The content was created using Dreamweaver CS6 and Photoshop CS6.

  I tried to view the page on other computers running IE, and they also have this problem.

  Any idea of what could be causing this to happen?

  Thanks for looking in this people!

  I discovered that prevented a few images to display in IE 11, while other images show. The culprit was Adblock Plus for Internet Explorer. Once, I disabled the software Adblock Plus missing images showed once again. Interestingly, I discovered that I could cause the same effect in other browsers using Adblock software. There is either a bug in the software of Adblock, or fluid network of Adobe system, which caused some legitimate images should be blocked. Whatever it is, they do not play well together right now. All images are stored on the same domain, and none of them related off site, so it's pretty weird that they have been blocked...

  Anyway, the mystery is solved! I know people like to see a conclusion to these things as much as possible, so I'll mark this as resolved issue.

• Why I can't convert to CMYK?

  I have a logo that I try to convert to CMYK. I'll select all layers, go to Edition, change the colors, and all options are available but "Convert to CMYK" is grayed out. I did with the other selections of many times before, and I don't know why it doesn't work this time.

  I thought maybe it was something on my pattern fill, so I chose the type of single-color, but I got the same result.

  Can someone tell me no reason that this could happen?

  Because your document color mode is RGB.

  Law of Peter, you don't want to do another task of color, because now you have one additional color plate. The mixture should be paper, white or a shade of 0% of 526U:

• Value that is used when you apply a gradient to an RGB image map

  Hello:

  I'm doing a classification of the color in Photoshop using the map of gradient, so the colors of certain range in the initial image corresponds to a given color chosen Gradient of.

  The final product is somehow predictable if the original image is an image in grayscale. However, if the original scale is a RGB image, value that will be used to determine the color applied to each pixel of the slope?

  There are several ways to calculate the luminosity of an RGB image, such as (0.2126*R) + (0.7152*G) + (0.0722*B) . I tried to use some, but none of them can be used to predict the actual color used by Photoshop to generate gradient.

  Does anyone know the formula used by Photoshop to determine with a pixel RGB is the color?

  Thank you

• After the recent update, when I open a RGB file it does NOT appear in the window of PShop. I need to convert to CMYK to the image correctly despite not wanting the RGB files.

  Anyone who sees this same anomaly?

  OK, we're almost. I suspect a graphics problem, but would you try a preferences reset everything first.

  Also let me know your OS: Windows or Mac.

  

• Image will not convert to CMYK

  Hello. I work in Photoshop CS4 and I ran across something that I've never met before. I got a picture, a psd file with a transparent background, use in a brochure, I'm working on that. The image is RGB. I need to convert it to CMYK for printing, but when I go to convert I gives me only the possibility of grayscale, Lab, RGB or indexed. It seems no matter what I do, CMYK is not in the Mode menu option.

  Anyone encountered this before? I don't know how this image was created or why it's like that, but any idea is appreciated. Thank you!

  Go window > workspace.

  I think that CS4 had the choice of the workspace of"base" that wouldn't show it to CMYK as a Mode option. If Basic is enabled, just check the default workspace.

• How to convert my RGB image or 8-bit?

• Can I change the resolution of the image or convert to CMYK first?

  Hello.

  To post a picture, I create a book cover.  The original image is a JPG in iphoto.

  When I copy JPG file on the desktop and 'get info '.

  size; 1 547 827 bytes (1.5 MB on disk)

  When I open the JPG in photoshop and image size , that's what I see.

  

  The criteria of creating files requires:

  CMYK

  resolution 300

  image dimension 5.25 x 8 inches.

  I tried many, many things without reaching the result I want.

  The image looks too grainy.

  Question1.

  What is the logical order to these settings for the more strong final image.

  
  

  Question2.

  I decided to do it too.  I thought it would be more logical
  

  File > new and adjust the setting here: cmyk and resolution.

  BUT when I incorporated place image, it came out very strange; a bunch of different colored squares.
  

  
  

  Question2.

  I read that a .pdf file is a quality superior .jpg so when I finished my changes I'll drop the .pdf in the cover model.

  Who will give me the best quality?

  
  

  Question3.

  Why are the different sizes of files between office and within photoshop?

  
  

  Question4.

  The image is of the ocean in the early morning, so there a bit of your Brown.

  I would like to have a Blue tint and I put the rest of cyan to-22.

  What is the best way to get the effect?

  I don't think that a moderator can delete images from your posts. You can post a request here or in the forum comments Forum.

  Since you're familiar with Indesign, I recommend that you use who and not PS for your design.

  When you create a new document, make sure you choose print new document under the intention in the dialog box.

  And use the file > Place to insert the image - do not copy and paste.

• png image will not convert to CMYK

  Hello Forum.

  I had an icon of the internet which is png, I open it in ps and its rgb in colour mode ofcourse.but I change the cmyk color mode and save it

  When I imported into indesign, the link information, he denounces his rgb! why it is not appearing in the CMYK color space?

  Thank you

  You can not save CMYK in PNG in Photoshop because PNG supports only the color mode. Most likely, you have saved as .psd or another format that takes care of CMYK (you won't notice when you clikk save you really has a Save AS dialogue) without realizing account and you place the original, not your conversion.

• ImgBayerColorDecode of NOR-IMAQ to produce 64-bit RGB images?

  According to reference Help feature, imgBayerColorDecode can be called with a void * pointer source and destination, so in principle it should be able to handle Bayer encoded images to 16 bits per pixel, right?

  However, when I look at this old net, it seems that it is not possible, because only 32-bit RGB can be taken out. When I look at the "Bayer Color Decode.vi IMAQ" on our system, the dll call is one of:

  "int32_t imgBayerColorDecode (int32_t dst, int32_t CBC, lines uint32_t, CLO uint32_t, int32_t dstRowPixels, int32_t srcRowPixels, const uint32_t * redGain, const uint32_t * greenGain, const uint32_t * blueGain, uint8_t bayerPattern, int32_t bitDepth, uint32_t reserved);

  But settings can be changed apparently. So my guess is that imgBayerColorDecode can now convert 16 bit Bayer coded images in RGB (A) 48-bit or 64-bit images (+ alpha), but I can't find any mention of this in the page "What's new with NOR-IMAQ".

  Can someone from OR Please confirm that it is possible today or is the old NET still valid?

  Hi Oliver,.

  During the period of SP1 2012, new Bayer decoding support added to the Vision. Bayer functions exported from the DLL IMAQ are discouraged because they don't have any of the new features. The functions are now in the Vision, but I think they do not need a license of the Vision Development Module (they are part of the basic API).

  The new functions of Bayer are significantly faster, have many algorithms of quality varying and support the conversion of > 8 bit to RGB64.

  imaqBayerToRGB() is what you should look into nivision.h.
