CMYK is the industry standard for printing because of the science behind the color space and the substrate. Ink on paper must use the CMYK color space to ach As we mentioned in your other posts there is no document color space with InDesign. You could only create and use RGB colors and place RGB images. If you are setting black text in a document that will be printed via offset, you will want the fill to be black only CMYK 0|0|0|100—RGB black will convert to 4-color CMYK at output. You need to go File > Export. Then select PDF. In the PDF export settings you'll have to select the 'Output' tab. Here it becomes important what you select (depending on the colors you want in your resulting PDF). For CMYK only, select 'Convert to Destination (Preserve Numbers)'. There can be problems with converting InDesign native colors, that you have to consider. Any black or gray colors built with black only will convert to 3- or 4-color (with the exception of the default [Black]). Pure primary colors like 100% cyan or 100% yellow might get "contaminated" with other colors. And yes once you do that you will not be The PDF’s CMYK color is DeviceCMYK (no embedded profiles). The Output Intent Profile lets the printer know what the expected CMYK output space is, but the color itself is not profiled. Spot colors are left unchanged. PDF/X-3 flattens live transparency, but allows a mix of CMYK, RGB and Lab process color—all RGB objects get an embedded profile. It might not be the end of the world to leave them RGB and have the printer convert to CMYK. The color won't be identical but it might not be a huge deal depending on what you're using it for. People say to convert RGB to CMYK before printing but that's only to ensure you get 100% accurate colors. gmUNeWw. 1 Answer. The CMYK gamut fits entirely into the RGB gamut. So, every color possible with CMYK is also possible with RGB. You won't get "clipped" colors moving from CMYK -> RGB. Vice versa is not true. RGB -> CMYK will possibly "clip" colors due to the smaller CMYK gamut. In general, this comes down to how finicky you are about color. Using Transparency forces the display to use “accurate colors” for your current Document Color space. Since not every color can be converted accurately from RGB to CMYK (InDesign's default color space), ID converts them to the nearest possible value. You are not printing the document — which does need it to be in CMYK space –, so you If it is going to converted to CMYK, why would I not want to work in that profile rather than RGB if there are color changes when converted? Hi , InDesign allows you to mix objects with different color spaces and profiles on the same page—if you check the document’s assigned profiles (Edit>Assign When added to a pure white image, these colors mask others: cyan absorbs red, magenta absorbs green, yellow absorbs blue, and black absorbs everything. This color absorption is why the CMYK color model is known as a subtractive process. Graphic designers set the intensity of each CMYK channel to produce their desired colors. CMYK and RGB are color models, which are meaningless without a color space to define those colors. Examples of common color spaces are Adobe RGB, sRGB, FOGRA27/FOGRA39 (CMYK), SWAP 2 (CMYK) etc. You need to make sure your InDesign document, placed images, transparancy blend space and export destination color spaces all match. The export to PDF/X in InDesign will auto-convert RGB to CMYK based upon profiles. I, personally, always convert PSD files to CMYK for print projects. I do not want to rely on any automatic color conversion. I'd rather see the CMYK and adjust if needed. But this is more my personal preference. There are many users that just use RGB and let
