    Ralf_Maeder got a reaction from Hofnaar in AD 1.6.4.104 - CMYK color conversion problem   
    I checked two RGB to CMYK online converters, and both convert R234 G116 B36 to C0 M50 Y85 K8.

    The value that Affinity uses for the conversion apparently is different from the industry conversion!?
    I really hope that this will be investigated by Affinity staff.

    There is TLDR at the bottom.
    So here is my simple, yet not popular answer - I do not know.
    But I know the solution - and I repeat - it's "work with your printing company".
    Why?
    It's plain and simple. Choose the color/rous you have trouble with. 
    Use CMYK or Pantone deck to decide while viewing with your bare eyes in the light condition you/clients will be viewing final product.
    Else, if you don't have color deck :
           A) Decide if it's worth getting one
           B) Print yourself some Pantones from Affinity (the one you think will be ok)
                and examine them with bare eyes, same as in above statements.
    Now you should have some basic idea which of the colours are better or worse. 
    Exact precise value is not important in printing, just because there are so many variables in printing technology, that each factory has it's own protocol - 2-3-5% of colour change or inaccuracy is usually possible. This is due to many things, starting from type of the media chosen, inks used, air humidity, post processing ingriedients used (like water) etc.
     
    Now when you are satisfied with the result, and you have your printed sample, bring it here so I can use my own eyes and my experience, than we will talk, and I'll decide, or we will together, using my own printed palette from the same software. 
    You see I use mostly Corel. When I print a proof from someone who used Adobe - colours will be differently translated. This why many if not all printing studious take vector files and like them better, or should I say postscript. TIFF is a form of bitmap, that can use named colors., but usually we like vector files where we can easily change colours so they will look as intended. 
     
    As long as you export colors by name and not by cmyk values you are safe.
     
    There is a whole another topic about color matching. There are software that help with that, but eye is eye, and in the end eye will tell
    Also keep in mind that there are not-web safe colors and also - another completly diffrent topic - non printable colors. We could talk for hours about those and I like it
     
    TLDR:
    Print swatches, examine which you like most. Send those to print production ask for proof swatches with named colors. Pick a number. Get colors you like.

    Here is for example Pantone 200C as seen and interpreted by 3 different softwares. This is why in many proffesionally made brand books you will see with logos :
    Pantone, HKS, CMYK, RGB, RAL, hell even both uncoated and coated versions, as good desiger knows there are many media types logos will be used and printed onto.
     
    Someone has to decide, clients ussually want the RGB color pop and vividness, juicyness of reds and greens. People are now used to OLED displays, and are usually not pleased with washed out colours on prints.. It's hard to explain them why they have to accept it. Some of them don't want to. 
    So to end this conversation, I will repeat myself again, work with your priting guys. They will help you to decide. And foremost always use named colors. They are here to help us. Color accuracy and matching is hard work. And it's not just so simple as "tell me which one is correct value".
     
    Thank you for reading this. I will gladly answer more questions or share my knowledge. In the end we are all here to explore and learn.

    I just checked the export of JPG with Facebook and Whatsapp without any issues. I suppose you are messing with the export settings or with a wrong file format.

    Ralf_Maeder reacted to curio in Several issues with the commercial plugin Ultraflares   
    Any news on this?
     
    Edit: Never mind, retried things with the current beta. Seems to work better: transparency's gone, strange error message still pops up occasionally.  Also, it suffers from the same color profile issues as do the Nik collection plugins in that ones other than sRGB result in false colors being displayed in-plugin.

    Ralf_Maeder got a reaction from Paul Bravery in Spot color separation preview   
    I would wish for a way to preview color separation without the need to use Adobe software or other commercial third party software. Another solution could be a new application from Affinity for this purpose.

    Ralf_Maeder got a reaction from Sullyman in Spot colors and preview color separations   
    I am a former graphics designer and worked 15 years ago in PrePress.
    Nowerdays I still use Macromedia Freehand on Windows for occasional design work and recently purchased Affinity Photo and Designer. 
     
    I was looking at the options related to spot colors and noticed that once I created a random color, I can't change this color to be a spot color. In order to create a custom spot color, I have to mark the "spot" box in the color creation tab the moment I create the color. This makes it tedious if the decision to use spot colors is made later on in the design process.
     
    Another issue is how to check or preview correct color separation in respect to spot colors? The reason I chose Affinity as my main tools is because I want to avoid the use of Adobe applications at all cost. Freehand can print separations, which can be saved as PDF and previewed without any third party software. What do you recommend as a workflow for Affinity Designer user in order to check separations of spot colors, but without the need to use costly third party software?
