CMYK JPG

Hi all

I use the DCT filter

I tried to implement with CMYK JPG in my PS application using the image with the Dictionary command.

Here is the correct parameterers

/ ImageType 1

/ Width www

/ Height hhh

/ ImageMatrix [[width 0 0 0 height]]

/ DataSource currentfile /DCTDecode filter

/ BitsPerComponent 8

/ Decode [0 1 0 1 0 1 0 1]

He did not - it displays the JPG as inverse balack

When I use the same way with different light settings to display RGB JPG and grayscale JPG IT WORKS very WELL.

Is not only CMYK.

Adobe supported this filter DCTDecode support JPG format, but perhaps in CMYK format, there was some development! and the DCT filter is not to support the last JPG with CMYK?

Here is the image of the sample and the result output

2.23 Harley 12x18-CMYK-In.jpg

2.23 Harley-CMYK_JPG.jpg

Concerning

Adam.

The values of the ink of the image are reversed, so you must specify

/ Decode [1 0 1 0 1 0 1 0]

to get the real picture.

  • Integrated PDF (CMYK) JPEG file

    Hello

    As I understand it the PDF specifications it is possible to directly include a JPEG file in a PDF.

    It must be encapsulated in an XObject object and its filter must be set to DCTDecode.

    (Even the JPEG header and others stored in the final PDF file)

    So I wrote a litte program PDFL Adobe that create these files by, basically, it reads all of the JPEG file using an ASStm [ASFileStmRdOpen()] which is called by the [PDEImageCreate()].

    I put in the call to Create() that the stream is encoded.

    Of course, it creates the appropriate PDEColorSpace in parallel.

    In the end it all works in RGB, I get the expected result.

    But when I use the CMYK JPEG file, the PDF I get is the negative of the image (as if I have applied time-> invert in Photoshop). I missed something for CMYK files?

    Below are the links to download the test files and the result:

    -CMYK (JPG) http://dl.free.fr/h2jecWBpj (PDF) http://dl.free.fr/gv5zecOEp

    -RGB (JPG) http://dl.free.fr/nccbrL1mg (PDF) http://dl.free.fr/ho5kqmkD4

    Thanks for the help.

  • Extract metadata from jpeg to PS CC 2015.5 file

    Hello

    Is there a way where we can extract the dimensions (width x height, in picas), color data (RGB, CMYK or grayscale) and the resolution of the image (in pixels per inch dpi). for a jpeg file, which was created in PS CC 2015.5

    Maybe a script or plugin.

    FYI - we want to make a batch to process more maybe 300 to 400 files to extract the metadata.

    Concerning

    Ray

    OK, here's the code ExifTool :

    ExifTool - r - line: ImageWidth - leader: ImageHeight - File: ColorComponents - JFIF: XResolution - JFIF: YResolution - IFD0:XResolution - IFD0:YResolution - IFD0:ResolutionUnit - csv "/ users/loggedinusername/Desktop/test ' > ' / Users/loggedinusername/Desktop/exiftool-metadata-dump.csv'ext - .jpg

    The output looks like this (reformatted for display of .csv):

    = /Users/loggedinusername/Desktop/test/IMG-CMYK.jpg

    Image width: 2448

    Image height: 3264

    Color components: 4

    = /Users/loggedinusername/Desktop/test/IMG-RGB-SFWL.jpg

    Image width: 2448

    Image height: 3264

    Color components: 3

    The first two images were recorded via file > save as, so that they have more information in them to be extracted. The third has been saved save for Web (inheritance), excluding all the metadata, so there is less info available.

    You may need to do a find/replace in a spreadsheet to replace the column component color, change 1 in grayscale, RGB 3 and 4 in CMYK.

    I can explain the CLI code more in detail if necessary (I applied to false syntax highlighting to help break the elements). This code is formatted for Mac OS, MS Windows would use all right double quotation marks ' and the------expected file path of formatting. "

    I hope this helps.

  • 600 dpi to 72 dpi

    Downloaded from this site today: http://www.newmeadowcamp.com . Everything seems fine on my imac and iphone. On the ipad, however, 4 photos on this page appear solarized: http://www.newmeadowcamp.com/who.html. They were initially wiped out of prints for the reproduction printed at 600 dpi. I tried different options in the menu of image resizing and, for example, with a picture although the menu resize says the photo has been saved to 172 x 248 to 72 dpi for a total of 166px, the photo appears in the folder to 766px.

    Someone could walk me through the image resize the process in a way that will allow them to appear correctly? Working alone here and would really appreciate the help.

    The images are CMYK jpg. Make it RGB and they'll look good on the iPad. Resize images once, not twice.

    The problem with pictures of the young leader is that they are CMYK jpg.

    CMYK is a print of the image mode. Web images should be RGB.

    Internet Explorer does not have the CMYK images (and there is no more need of)-However, most of the other browsers seem to.

    The solution is to open photos in Photoshop (or whatever image editor you use) and then convert them to CMYK in RGB

    In Photoshop: Image > Mode > RGB color

  • Is there a trick to convert JPG of RGB to CMYK without re compression with loss of?

    So I have around 750 images for multiple folders and categories. Each image has 6 variants - TIFF 16-bit photographer Beaver excessively eager, TIFF 16-bit, extracted from circles (performed by student workers, who are not English that we are not in the United States), then standard 3000 x 2000 (or other image format appropriate) PNG with answer keys for print edges Web and light, a JPG of 1800 x 1200 for the web and a few smaller also for web PNG standards.

    TIFF 16-bit with BG retrieved is the root files, and a series of actions draws the PNG. The PNG standard is then pumped through actions and image processor to create output files.

    So, I just found out that a seemingly random number of them are in CMYK mode. That was not a problem until now, because our Web site and our printed documents have no problem with CMYK and RGB files.

    But now we are starting to distribute these images to our customers - who are only interested in the JPG of 1800 x 1200 and perhaps 900 x 600 PNG, which are more easily drawn directly from our Web site files rather than by sending them all the 180 GB graphics directory.

    And some of them say that the photos are rejected. In particular, are not allowed the CMYK files.

    So limit the damage - rebuild our entire library of images of the 16 bit TIFF

    OR

    rebuild only a couple of different sizes and download from there, by replacing the images on the next major release (report to next year).

    I'm * NOT * anxious to preserve the color, since 99% of our products are black and shades of gray, with only a hint of color.

    I am concerned about the degradation of the mode change on 60-70% images compressed, and then re-register again with the JPG lossy compression.

    I'm about to start tearing into things with my actions and replaced nearly 1500 files online, so I would like to be sure I'm doing things in the most appropriate way.

    If there is a tool that can do this conversion without another passage of compression, this would be ideal.

    Whenever you register or book a JPEG, it is re-compression.  No exceptions, no work around.  No magic 'tool that can do this conversion without another passage from compression' If you want to end up with a JPEG re-recorded.

    JPEG is a lossy format.  Period.

  • Import jpg color problem

    I am importing jpg files in FCP7 and color moves (loss of cast red/green)

  • Does anyone know why EP 11 will not import Corel Photopaint (v.  (13) jpg?

    Earlier versions of the program had no problem doing this. There seems to be no problem in jpg created elsewhere, but since a large part of my work is done in PhotoPaint, it really becomes a burden. Many of these files are quite small, so I'm pretty certain size is not a problem.

    Thanks in advance for your suggestions

    Terry...

    Thanks for the suggestions. They led me to the solution: the default output for PhotoPaint is apparently CMYK. I changed RGB, and that solved the problem.

    BTW, PhotoPaint is not obsolete. The latest version was only offered with the latest CorelDraw Graphics Suite.

    See you soon.

  • 'Transparency' (not CMYK) not allowed, issue controls upstream

    Hello

    I'm having a problem with the option of preflight and transparency. I chose the CMYK for space, a little more merge transparency option and 'use transparency'.

    10 Psd have transparency applied in the Panel info links but they have no more than one layer and the color profile is CMYK Fogra39. Obviously, If I uncheck the 'use transparency' errors disappear.

    How can I remove this value from transparency of the PDS? (A single layer PSD, any applied effects, without channel alpha etc., JPG only imported to the PSD file to convert them to CMYK. I used the PSD to avoid the problem of the quality).

    Thank you to all will answer and help me with this problem.

    Yes it's true. It is not intuitive, but you can have a number any of transparent objects, il y a until a background layer ID does not see PSD as containing transparency. You can run background layer if you don't want to flatten.

    ID is the transparency in the top image, but not the version with a background

  • JPG color change

    Greetings.

    I have an image I created in adobe illustrator that I would use as a background for a Web of Muse site.

    When I drag the .jpeg file into muse since my finder window, the background appears, but it is quite the neon and bright compared to the file to open in other programs.

    It is quite possible that you use a JPG file that is CMYK (for printing) instead of RGB (for the web).

    If you "save for Web" (main file menu) in Illustrator, which could help.

  • How to register properly for CMYK/RGB without changing color?

    I have 350 - something icons that are in different color combinations. I tried earlier correct colors, like the colors of profile where I work have changed over the years (Ref: change the colors of the icons in different files). Lately, I noticed that the colors have changed when I save in Illustrator. If a color orange which is supposted to be CMYK: 0, 43, 90, 0 ends up being 0, 43, 89, 0 instead of this (or any other variant).

    Now I'm really hoping to get rid of the problem. I'm thinking of changing the orange color manually, and hopefully change the color icon in the manner described in the linked post to the. I also think about saving icons in another format and color mode. I did it earlier, but I lived to change color.

    My icons are now in .eps with CMYK document mode files.

    I'm looking through:

    CMYK:

    -eps

    -tiff

    RGB:

    -jpg

    -rgb

    -svg

    Does anyone have advice good savings on these format, without getting colorshifting?

    Check your color management settings.

    There should be no conversion on opening the file.

    When converting to RGB but you have to wait the color "changing." Numbers can not just stay the same.

  • 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?
