  1. Following your post, I tried all PDF-X versions that Affinity Designer offers with no luck. Also coverting the letter to curves did nothing to the overprinting. Seems I am out of options. Black overprinting should be pretty basic standard for a serious graphic design software.
  2. I am designing a simple flier in Affinity Designer and want to save a PDF for the PrePress. When I check the CMYK separations in Adobe Acrobat Professional, I am observing that Black text is not overprinting over a colored background, no matter if I use the default black color or a newly created global color C0 M0 Y0 K100 with Overprint activated. I suppose I have to trust Adobe Acrobat that the overprinting instruction is not translated into the PDF file. My document is correctly set up in CMYK. I suppose it's an issue with Affinity Designer. I would like to know beforehand if the software can handle black overprinting accordingly. My only tool to check this is Adobe Acrobat Professional, unfortunately. Opening the PDF in Affinity Photo and checking the CMYK channels, also shows that black is knocking out, though I suppose that AP is not capable of recognizing overprint in a PDF even though it was created by its brother Affinity Designer. Any idea guys? overprint issue.afdesign
  3. I would check once again the settings of your imported images. Maybe they include more channels than expected (multichannel, or 16bit, etc.) or CMYK color coding and things get messy once you print or export the artwork!?
  4. I am using my licenced versions of DOF PRO 5 and ULTRAFLARES by Richard Rosenman. http://richardrosenman.com/shop/dof-pro/ http://richardrosenman.com/shop/ultraflares/ Computer Xeon 2687W v4, 12 cores, 32 GB RAM, Windows 10 Pro. Issues with DOF PRO 5: 1. First of all, once I hit "OK", there is no progress bar. Depending on the settings, calculations with this plugin can take a couple of minutes, so it is no gimmick to count with a visible progress bar. Meanwhile the plugin calculates, Affinity Photo hides the display of the displayed image and shows no activity at all nor is it possible to interact with the software. It appears frozen until the calculations ultimately finish. Issues with DOF PRO 5 and ULTRFLARES: 2. Another issue is that settings made inside the plugin are not stored during the same session, making it necessary to reenter all values every time that I open the plugins during the same session. 3. A third issue is that after a second access to the plugins, Affinity Photo displays each time a warning message. This applies to both Plugins, DOF PRO 5 and ULTRAFLARES: Warning Aborting X86_call_fmf1 -- code not valid. OK CANCEL Entering OK opens the UI of both plugins once again, with no apparent malfunction. I am comparing these functionalities with Corel Paintshop Pro X9, where none of these issues is present. Ralf Maeder

    AD - CMYK color conversion problem

    Thanks a lot mrqasq for diving once again into this topic. Your comparison between Photoshop, Corel and Designer is pretty convincing: every software uses its own interpretation of color conversion between RGB and CMYK. I didn't expect so severe differences. But, like you said (in other words), we have to accept this and define our colors with professional means like color guides and with the help of PrePress professionals. Despite this, Affinity should at least make it's own algorithms coherent throughout the software. Ralf Maeder.

    AD - CMYK color conversion problem

    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.

    This is how AD crash and make me upset

    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.

    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.

    AD - CMYK color conversion problem

    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

    AD - CMYK color conversion problem

    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.

    CMYK - 0/0/0/100 is grey

    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.

    CMYK colour glitch

    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

    CMYK colour glitch

    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

    CMYK colour glitch

    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
