surge Posted July 28, 2019 Share Posted July 28, 2019 I have created an extensive document with many PNGs with transparency. I want to provide and compress them as PDF eBook. However, with normal printing of the compressed PDFs, the images are printed with a black background. This does not happen when printing uncompressed PDFs. Here the printout and the file: Quote Link to comment Share on other sites More sharing options...
thomaso Posted July 28, 2019 Share Posted July 28, 2019 What do you mean with "PDF eBook" and with "uncompressed PDF"? Can you upload your .afpub with 1 page with text & PNG example? And/or both of your PDFs? Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
surge Posted July 28, 2019 Author Share Posted July 28, 2019 Here come the export and print properties. I've tested the printout and it was again black for the transparent areas. Also attached are the test pdf and afpub. Drawtut eBook test.pdf Drawtut eBook für test.afpub Quote Link to comment Share on other sites More sharing options...
Staff Pauls Posted July 29, 2019 Staff Share Posted July 29, 2019 Can you send a screenshot of the more settings in the PDF export please Quote Link to comment Share on other sites More sharing options...
thomaso Posted July 29, 2019 Share Posted July 29, 2019 I assume the issue of black printed transparency is related to limited postscript capabilities of your printer. I can't find the reason in your files for the issue. Also your PDF prints without this issue for me. In your screenshot of export setting the relevant details of the "More" section are not shown, all I can see is that the PDF got rasterized at least partially though the PDF appears to be a 1.7 version. Again, what do you mean with "PDF eBook" and "uncompressed PDF"? If you want to get a printable PDF then I recommend to change some color settings before export (though they not necessarily influence the problem): – Switch the Document color space from sRGB to CMYK (... and export with an unchanged default preset, or as CMYK with CMYK profile) – Switch the text color of RGB black to K only There is a strange occurrence in the blue headline on the master page: In your PDF I do see a white stroke around it with a thin grey border. I also see this in your .afpub when zooming. Such a thin grey boarder also gets visible around the illustration when zooming, and gets exported, too.

surge Posted July 29, 2019 Author Share Posted July 29, 2019 Here comes the pdf export properties (German). eBook is for me a possibility to create my book as a PDF to deliver it digitally and people can print some pages out if they want. Uncompressed is if I leave the picture resolution on 300dpi. Quote Link to comment Share on other sites More sharing options...
Staff Pauls Posted July 30, 2019 Staff Share Posted July 30, 2019 I've not been able to recreate the issue either - Have you got the latest drivers for your printer. Can you let us know the make and model please Quote Link to comment Share on other sites More sharing options...

It his hard to understand for me because you use words in a different than the common meaning. Do I understand you correct, that you experience: – transparency prints black if you set the export resolution to 192 dpi – but it prints transparent with export resolution of 300 dpi Falls das Problem weiterhin besteht: Wenn es für dich leichter und evtl. weniger missverständlich ist, dann antworte auf Deutsch statt Englisch.

surge Posted July 30, 2019 Author Share Posted July 30, 2019 That is exactly what happens. Black at 192 and transparent at 300dpi. Update of the printer driver is not possible, because the Mac installs and updates it automatically. But I will try it on an other printer.

ClearWood Posted April 13, 2020 Share Posted April 13, 2020 Hello, I am having what appeards to be the same problem noted in the above chain of posts. I note that the post seems to be un resolved / problem unreproduced. The only reference that I have found that might address the issue is the following https://answers.acrobatusers.com/Why-are-my-pdf-files-printing-with-a-black-background-and-white-letters-like-a-photo-negative-q214562.aspx I will give the suggestion a try and report back if it works.

So I assume this PNG black background print issue is not limited to a specific print setting (as in your linked suggestion) and even not to a specific combination of app + printer + operating system but may rather be related to the fact that PNG isn't made for print but onscreen view. In this recent posts the issue could be avoided "simply" by the use of a different printing app (mac, Preview.app –> windows, Adobe Reader.app /// mac, Preview.app –> mac, Acrobat X Pro.app) (whereas in this sample the involved files aren't really clear due to a mixture of various imports and file formats): Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
ClearWood Posted April 13, 2020 Share Posted April 13, 2020 Hello Thomaso, You are correct, it is not the only reference to the problem. It was the only one that I had found that seemed to offer a possibly promising clue to the problem. That said, I was happy that in my particular instance, that the change to the color profile worked. Also in my instance, the problem was not specific to a particular printer. The transparent background of that particular layer in the exported PDF printed black on both a Canon Pixma and HP printer until I changed the color profile and re-exported the PDF. Wish I had more conclusive data. Best regards Quote Link to comment Share on other sites More sharing options...
CJ Cal Posted June 12, 2020 Share Posted June 12, 2020 I suddenly have a similar issue in June 2020. My husband's Mac has Catalina 10.15, recently updated. My Mac has El Capitan 10.11. Use the exact same printer, EPSON WF7720, my Mac prints our company logo image with a white / transparent background (desired). Suddenly my husband's Mac prints the same file with our logo appearing to have a black background. The only change is his Mac got updated. Rebooting, reinstalling the printer driver...nothing has solved the issue. Quote Link to comment Share on other sites More sharing options...
ClearWood Posted June 15, 2020 Share Posted June 15, 2020 Hello CJ Cal, Best of luck. As noted, in my last post on the subject, only the color profile change worked for me. Quote Link to comment Share on other sites More sharing options...
ajpearceUK Posted July 16, 2020 Share Posted July 16, 2020 (edited) Same problem here. I am able to work around it by losing the PDF export function of Designer and instead using the pdf print option built into OSX via the print dialogue. However, that loses all the functionality options built into Affinity Designer, such as being able to specify the type of PDF I want to make. Funnily enough, enabling 'Simulate Overprinting' in the Adobe Acrobat DC print preview dialogue doesn't help me to see the problem. I literally have to physically print it to see if it's going to be a problem. Not good. I hope my workaround helps. Clearwood, for the colour profile tweak, what exactly did you do? In my printer options for my Brother printer the the options are slightly different. edit: Another way is to use FLATTEN PDF Edited July 17, 2020 by ajpearceUK Quote Link to comment Share on other sites More sharing options...
Josep Posted October 9, 2020 Share Posted October 9, 2020 Had the same issue. Black square around the image in a PDF file. The problem was that I printed from "Vista Previa" The PDF viewer that comes with MacOS (Spanish name) When I printed from Acrobat Reader it automatically fixed the problem. Hope this helps!

tristdrum Posted February 4, 2021 Share Posted February 4, 2021 For others with a similar problem, without need for quality, simply screenshot the image (first try make is fill up the most pixels on your screen) & print the screenshot (with the quality side affects that come with it) for a quick fix solution.

Alternatively, to achieve resolution than a screenshot: Export the layout from Affinity as JPG / or Export from your PDF viewer app as JPG.

CP16 Posted October 28, 2021 Share Posted October 28, 2021 I’m having a similar problem, except my diagrams are copied and pasted from Designer into Publisher. I’m not saving the images. It only prints the black area if I print the PDF in color. It prints fine if I print in B&W. Quote Link to comment Share on other sites More sharing options...
