  1. The user Matej Junk explained his findings in above posts. I worked a couple of years in PrePress and know one or two things about these matters. But for the sake of the question of Matej, could you indicate us the correct conversion values of the color R234 G116 B36 and if Affinity Designer values are congruent? Color R234 G116 B36 Color format CMYK/8, Color profile U.S. Web Coated (SWOP) v2: Affinity Designer C4 M69 Y100 K0 Online converters C0 M50 Y85 K8 https://www.rapidtables.com/convert/color/rgb-to-cmyk.html Macromedia Freehand converts to C8 M55 Y88 K0 Especially the RGB to CMYK conversion of Affinity Designer is so important because of many artists who don't have the knowledge of professional color printing.
  2. In my case, I had two crashes with the latest official build of Designer. One happened when I didn't even had saved the file for the first time, so all the work was lost. Which reminded me of the old habit to save naming the file as soon as possible and after that just use Ctrl+S very often. Also doing sequential saves could prove beneficial with such new software like Designer and Photo which are updated very frequently with new builds and there is a slight chance that newer builds may cause problems with saved files or corrupt them. I suppose we will have to be patient with this new software packages and take care ourselves working intelligently in order to minimize the chance of lost workfiles. In my case I am more than willing to do so, because I decided to avoid Adobe and my work is just inhouse for my own business. I agree that for professionals unstable performance can be a big issue.
  3. Something that I learned the hard way from many years in PrePress and graphics design, save often and additional to that, make sequential saves. Software does crash and in the moment when they can cause most damage, Murphies Law.
  4. I checked two RGB to CMYK online converters, and both convert R234 G116 B36 to C0 M50 Y85 K8. https://www.rapidtables.com/convert/color/rgb-to-cmyk.html 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. Ralf Maeder
  5. I haven't tried to replicate your error and line of thought. Looking at the color settings of your document, it says color profile "convert". Can it be that the selection of "convert" messes up your color conversions? None of the less, your findings show incongruencies that Affinity should check out.
  6. The screen representation of black differs depending on the chosen color format in the document setup. This is just cosmetical if I may say so. See attached screen copy.
  7. I created a dummy business card with black color elements (c0 m0 y0 k100). Exported from Designer as "PDF (for print)". No pixelization occuring. Find attached Designer file and PDF. Greetings Ralf Maeder business card black white test.pdf business card black white test.afdesign
  8. Normally a black color as used in business cards etc. would be defined as c0 m0 m0 k100. Adding more color channels to the black color can add bleeding in PrintPress because each color is printed in sequence and therefore the machine has to be adjusted painstakenly exact in order to avoid bleeding. You will obtain better defined results if black is only achieved with black and nothing else. In respect to the pixelization of the background rectangle I would dive once again into the Designer file and make adjustments or create it from scrap. Maybe at some point you added an effect to this element or added layer effects to the overlying text and as a result, Designer had to rasterize the rectangle!? Greetings, Ralf Maeder
  9. Hello, I am also german and worked a couple of years in PrePress and graphics design. I don't know how much you know about printing and colors. I assume that you would define the black color as only black, no need to use a full color black. Black should contain only black in your case. The vertical artifacts are another issue and are indeed strange and only explainable as an export bug in my opinion. In order to correct the issues, you should first define the color as black color only or spot color and apply the changes to all elements that need this color. Then you should export the file from Affinity Designer as PDF. If you just print the PDF, the colors are changed due to the fact that all printer profiles work in RGB. Hopefully the vertical artifacts won't show up any more. Opening up the PDF in Acrobat Pro, I can see that the black box shows pixels, which means that it was pixelized, either by the export or by some previous user action. Ralf Maeder
  10. I can reproduce the issue. If I change to "WARP" renderer, the artifacts are a lot less.
  11. 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.
  12. The offset-press would prefer native files for Adobe Illustrator, I am pretty sure of it. Since current Illustrator versions can't handle any more Freehand files (and operators are pretty much unfit to open non-native files or correct mistakes), my only safe way is to deliver a Final PDF for printing, which would be used by the PrePress studio to do the separations. I just want to be able to preview separations in order to prevent mistakes being made with applying correct spot colors (if present). Hope that makes more sense now?
  13. On occasion I do design jobs which need to be send to the Press. Living in Guatemala, Central America, up to this moment I used Freehand for this purpose, saving a vectorized Freehand file and a PDF for control, not as a final print file. With Affinity Designer, the only filetype with predictable results is PDF. I wasn't aware of the difference to either export a PDF or print a PDF with Acrobat Professional. I assumed Acrobat Pro would be more than capable of generating a more than apt PDF file, more than Affinity I assumed. Well, seems I was wrong about that. Apart from that, I use Acrobat Professional in order to check correct spot color separation prior to pass the file to the Press.
  14. I posted my question in a Facebook group and got a useful explanation: I have to export the PDF file. Only then the CMYK colors stay intact. If I print a PDF with Affinity Designer, the CMYK colors are affected by the printer profile, which is always RGB. In my opinion, the printing panel of Affinity Designer should include some warning that the printed PDF is not suitable for PrePress.
  15. I have several issues with colors and spot colors in Affinity Designer. One problem was found when making a simple test in order to test process colors (4c). I created a new document with CMYK color format. I created a new global color with the CMYK slider, Cyan 100%, M 0%, Y 0%, K 0%. Just for testing if Designer makes a difference, I also created a second color with RGB sliders, R 0, G 176, B 240. Created two primitives. Each one is assigned one of the two global colors. Saved the document. Printed with Adobe Printer (Adobe Acrobat Pro XI) and opened in the same application. When I choose print and advanced options, I see the 4 plates Cyan, Magenta, Yellow and Black. Turns out that both Cyan colored primitives have 100% cyan and a percentage of magenta also. (For the sake of it, I also printed with Microsoft to PDF printer and the result is exactly the same.) Obviously this is a big issue. A color defined as 100 Cyan should never end up as 100 Cyan and a bit of Magenta or anything else. Ralf Maeder See attached files.
