save your RGB file. convert it to CMYK and save it as a new file. open both the RGB and the CMYK files in photoshop. set them next to each other and compare the colors. now you have to adjust or saturate some colors in the CMYK file. there’s different ways but a good one is to do it with the adjustment layer „hue/saturation“ where you can I have four TIFF images each ~20Mb (around 75000px by 45000 px). I want to import all four in Illustrator, color them in CMYK (weird that Illustrator shows they are around 800px by 500px) then press on transparency, Multiply. However, the file size given by Illustrator is 1.7GB and I cannot print them because Illustrator keeps crashing. If the tab is displayed as (CMYK/8), then your artwork is already in CMYK and there is no need for conversion. Step 2. Access the color mode through “Mode” from the “Image” tab on the top corner of the software. You will notice that there is a tick on RGB color as shown below, so you can correct it by picking the CMYK Color option Yes, if both use the same settings, the result is the same. The Image > Mode command was around long before Convert to Profile. Image > Mode uses the “locked in” colour settings, while Convert to Profile can change settings “on the fly” with live preview. For most conversions Image > Mode has been depreciated and Convert to Profile is In the New Document window, simply change the color mode to CMYK (the Photoshop default is RGB). If you want to convert an image from RGB to CMYK, just open the image in Photoshop. Then navigate to Image > Mode > CMYK. Era89, flatten all layers before converting to CMYK. This will save a good number of the vividness and vibrance because RBG to CMYK and vice versa conversion works better with a single layer. Mulitple layers will result to off colors. After the conversion, use some adjustment filters to boost up certain range of color strength/vividness. Only a slight move is needed to give your image some color. 4. Convert to CMYK. Blurb’s plug-in for Adobe InDesign and Blurb’s PDF Uploader work best with CMYK images. If your images are already in CMYK and you're done editing them, you're all set. Put your CMYK images directly into InDesign or whatever program you'll use to create your PDF. I joined Maker Studios & so can you!Click here to see if your channel qualifies for RPM Network/Maker Studios: http://awe.sm/cECTzin this clip I will show yo Acrobat will usually use the Simulation Profile to display. So if your image is in a (large) RGB Space it may be displayed in a (smaller) CMYK Space, even though the pdf contains the RGB data. Please post screenshots from Photoshop (with the Status Bar set to »Document Profile«) and Acrobat (with the Output Panel visible). Upvote. If you are experiencing a color change or color shift after exporting and saving in Photoshop, then you need to adjust the color settings and color profile. Yv7LUp.
