Exporting QR Codes

[Pbj]

I have a bit of trouble exporting my layout. The layout contains qr-codes.

I have imported them as png (Only 2 Colors, black&white into affinity publisher and when I zoom in affinity I get clear edges (black/white) no matter how far i zoom in.

 

However, as soon as I export them as png for example the edges are getting washed out and therefor contain more colors then the previous two (black&white).

Since this qr Codes are for a print product I see problems with the end result because of this.

Is there any way I can export these in two colors(black&white) and preserve the details on the edges?

Any help is very much appreciated!

Hi @Pbj

Which colour profile does the document have? And which colour profile do you use for export?

[Pbj]

I set the document colour profile to iso coated 300 V2 and also try to export it in this setting.

Change "resample" to "nearest neighbour" on the export settings.

On top of all this, check, if pixel alignment is active. Otherwise your QR code might be placed on a fraction of a pixel, which causes anti aliasing on export.

Thank you all for reaching in. With your help I managed to get clear edges.

However as soon as I try to export the layout in CMYK the black is getting a mixture of all colours and not CMYK(0,0,0,100). If I export it as RGB the black stays black. What could be the problem here?

Understand that I know 5/8 of not a lot about CMYK so if this is tripe I'm sorry
