QR code exports pixelated


Recommended Posts

Hi all,

All of a sudden my QR codes are exporting very pixelated when in the past, they have exported fine. 

I am wondering if this started happening after my update as usually I can export a final file as High Quality PDF with no issues. 

 

Export settings: PDF > For Export > Allow advanced features

I can’t be sure but the problem looks like it’s because the QR Code (layer name “bit.ly_boar-barra”, in various places) isn’t pixel-aligned.

Make sure that the X, Y, W and H in the Transform Panel are integer pixel values and it should work better.

Do you have an example where they exported better? I doubt that you could get better results with the current set of parameters like size, color usage (rich black) etc.

The QR code is a bitmap in CMYK color format scaled down to 20% and and not pixel-aligned. The bilinear resample will lead to blurriness.

You can regain some contrast by adding a threshold adjustment

Hi @Beck,

Is there any reason for not using a vector QR Code such as the attached...

This is also what I would have suggested, as raster images are often pixelated, which is not suitable for a Quick Response Code with a long URL.

6 cœurs, 12 processus - Windows 11 pro - 4K - DirectX 12 - Suite universelle Affinity (Affinity  Publisher, Affinity Designer, Affinity Photo).

Mais je vous le demande, peut-on imaginer une police sans sérifs ?

Hi all,

Thank you for all your comments and input! 

I had changed our QR code to SVG file and this helped a lot with exporting it crisp and clean! 

I handover these files to a printing team that prints the shirts so I need to provide files in High Quality and also editable so they can adjust things into their template. The team use Adobe Illustrator and prefer .ai file but I can only provide what Affinity exports. 

If anyone knows which is the best File & Export settings to use, I would appreciate your input!

I usually export to PDF with settings: For Export - No compression on images - Allow advanced features.

Just curious to see if there are better options out there to ensure my printer has the best file possible for the job!

Thank you!
