PaulWilliamson Posted February 16, 2021 Share Posted February 16, 2021 Hi! Do I have to take each layer that is in RGB and find out what the corresponding CMYK colors are and convert them to them? I would like to keep the logo the same but in CMYK and have another version of it for print purposes. Thanks! -paulw Quote Link to comment Share on other sites More sharing options...
walt.farrell Posted February 17, 2021 Share Posted February 17, 2021 Make a copy of your document, and in that copy: File > Document Setup On the Color tab, change RGB to CMYK, and pick an appropriate profile. Click Convert if it's not selected. Then click OK Quote -- Walt Designer, Photo, and Publisher V1 and V2 at latest retail and beta releases PC: Desktop: Windows 11 Pro, version 23H2, 64GB memory, AMD Ryzen 9 5900 12-Core @ 3.00 GHz, NVIDIA GeForce RTX 3090 Laptop: Windows 11 Pro, version 23H2, 32GB memory, Intel Core i7-10750H @ 2.60GHz, Intel UHD Graphics Comet Lake GT2 and NVIDIA GeForce RTX 3070 Laptop GPU. iPad: iPad Pro M1, 12.9": iPadOS 17.4.1, Apple Pencil 2, Magic Keyboard Mac: 2023 M2 MacBook Air 15", 16GB memory, macOS Sonoma 14.4.1 Link to comment Share on other sites More sharing options...
PaulWilliamson Posted February 17, 2021 Author Share Posted February 17, 2021 Hi Walt! I do not see the convert option. Please see attached. Thanks again! -paul Quote Link to comment Share on other sites More sharing options...
BofG Posted February 17, 2021 Share Posted February 17, 2021 @PaulWilliamson when going from one colour space to another (like here where you are going from RGB > CMYK) there is no option to assign, you can only convert hence those options are disabled.

Fixx Posted February 17, 2021 Share Posted February 17, 2021 Mind you, this way it is easy to make black text and vectors go rich black (something like C89M78Y62K97). Usually this is not desired. I do not now how to convert RGB000 to K100, other that select objects and adjust values manually. Quote Link to comment Share on other sites More sharing options...

There should be a swatch that preserves black, or an option when converting to map 0,0,0 rgb to 100k. The best you can do now is define a spot colour of 100k and use that, it will survive conversion. It does then result in an extra channel on export to pdf, but any RIP/prepress should be able to handle that and shift it onto the K plate.

The Assign/Convert is only for changing profiles within a mode.

PaulWilliamson Posted February 17, 2021 Author Share Posted February 17, 2021 Thank you so much! But it looks like the individual colors were not saved as CMYK so I manually converted them. Simple logo so no biggie. -paulw Quote Link to comment Share on other sites More sharing options...

PaulWilliamson Posted February 19, 2021 Author Share Posted February 19, 2021 Hi, No matter what I tried, the document colors are not saved with CMYK colors. I tried the document setup suggestion, and I also clicked on the colors on the RHS tabs and on the fill color on the context menu. I think I saw a slight change in the colors when changing them to CMYK but when I exit Designer and reopen it and the document, the CMYK colors I set are gone. For instance, in the attached file, the green background underneath Exit333 should be Highway Green (CMYK 64,0,47,48) but it is now 81,25, 94,11 in the Fill CMYK Slider. It was not that when I was working on the document. Also, RGB for Highway Green is 48,132,70 but it is now 51, 132,69. I have not sent my logo off to a printer on a document but I think it would look fine. Just curious how to convert an Affinity Designer file colors to CMYK since it doesn't appear to work. What if I started an AD file in CMYK, if that is possible? I am sure I am doing something wrong! Thanks! -paulw exit333logo - CMYKConvertedAttempt2.afdesign Quote Link to comment Share on other sites More sharing options...

BofG Posted February 19, 2021 Share Posted February 19, 2021 RGB document profile = rgb colours CMYK document profile = cmyk colours Anything shown in the colour picker that is not the same colour mode as the document (e.g. cmyk sliders in an RGB document) are conversions based on the default profile that is set in your preferences. Setting a colour using the cmyk sliders in an RGB document does not give you a cmyk colour. To go from one to another you have to convert the document colour space as mentioned before. The other thing to bear in mind (which confuses a lot of people) is there's no such thing as an RGB colour or a cmyk colour - you need a profile for the values to mean anything. "Highway Green" will be different values in SWOP, ISO coated etc etc. Quote Link to comment Share on other sites More sharing options...
PaulWilliamson Posted February 19, 2021 Author Share Posted February 19, 2021 I think I get it now! 🙂 I created a new CMYK color document and copied and pasted from my original afdesign file. Then I changed every color to CMYK. The default sliders were in CMYK. I saved the document without converting then reloaded it just for test and everything was still in CMYK. Great learning exercise! Thank you so much, especially for "The other thing to bear in mind (which confuses a lot of people) is there's no such thing as an RGB colour or a cmyk colour - you need a profile for the values to mean anything.

Nearly got it As your destination document was CMYK, your pasted elements would have already been converted. All you need to do is "save as.." to get a copy, then go to the document setup, colour tab as show earlier in this thread, and select the cmyk profile you want and the colours are all converted for you.

PaulWilliamson Posted February 19, 2021 Author Share Posted February 19, 2021 Hah!! Well, I got it done and learned a lot from this post. There are so many nice and knowledgeable people here. I do have the AD book and tons of all Affinity courses at Udemy and other places and I am going to set aside as much time to go through them all. However, there is nothing like learning from the people here on the forum! Books and courses do not always cover all "real life" situations, IMO! I have attached the final CMYK file. Please let me know if I missed anything 🙂 Thanks so much! -paulw exit333logoCMYK.afdesign Quote Link to comment Share on other sites More sharing options...

lepr Posted February 20, 2021 Share Posted February 20, 2021 Warning: some of the following information contradicts statements seen earlier in this thread. Converting an Affinity document from one colour mode (e.g. RGB, CMYK, Grey, Lab) to another does convert the colour mode of Pixel objects, but it does not convert the colour mode of vector fills and strokes or the colour mode of swatch definitions. For example, say a document is RGB and contains a vector rectangle with fill specified as RGB(48,132,70). If the document is converted to CMYK, the specification of the rectangle's fill remains RGB. Again, say a document is RGB and contains a vector rectangle with fill specified as RGB(48,132,70). If the rectangle is copied and then pasted into a CMYK document, the specification of the pasted rectangle's fill remains RGB. To see the true specification of a colour, two things need to be done to the Colours panel before selecting an object for inspection: set controls mode to Sliders in the hamburger menu disable the colour mode lock (padlock button) Quote Link to comment Share on other sites More sharing options...
BofG Posted February 20, 2021 Share Posted February 20, 2021 1 hour ago, anon2 said: the specification of the pasted rectangle's fill remains RGB That may be "behind the scenes" but the displayed colour is converted, and if you export to a format that supports mixed colour models (e.g. pdf) you won't get a mixed output. To all intents and purposes, the colour model of the document is what you get. I understand what you are saying, technically the object's data isn't converted, my point was the result won't be an RGB "colour" in the display, or in any export. If the document pasted from and the target document are both in the profiles as the defaults then I believe the shown values will be correct, unless I'm missing something? You can place an image of a different colour model, and that is maintained on output to pdf if set that way, however as Affinity cannot display mixed colour modes it won't show correctly in the app. Quote Link to comment Share on other sites More sharing options...

PaulWilliamson Posted February 20, 2021 Author Share Posted February 20, 2021 So if there is a chance that an AD or AP document will be used in a brochure or business card or whatever print document, instead of just on a web page, what should the process be for that? What if it is a detailed Designer document? Start with CMYK instead of RGB? -paulw Quote Link to comment Share on other sites More sharing options...
