pdf image export BAD (Designer)

[Thomahawk]

Designer V2 mac monterey

Exporting a PDF that does include a qr code b/w image (see left sidein Designer), whatever I set in PDF export, even with PDF resolution set to 1200 dpi and no downsampling, the resulting PDF still includes the QR code in Low Res. (see image right side)

What else can be done?

Even when I export a PDF, set 1200 dpi, or even set to not render and no jpg compression, the result was always the same Low Res QR code. This should not happen! In that case it should stay sharp like the image on the Designer artboard.

In afPhoto it showed the qr code was 22x22 pixel in size. The only solution was I changed the resolution to 2200x2200. But this should not be necessary when no rendering and no compression is done for the pdf export!

Could you upload a sample document here?

Nothing wrong on my side with PDF Press-ready preset on Win 10. Could you post screenshots of your export dialogue?

QR codes are coming out blurred for me to on Catalina. Could it be a Mac v Windows bug?

What happens, when you rasterise the layer with the QR before export?

[markw]

Ah yes, that fixes it! But should that step really be necessary?

I would say No, so this thread could be worth a bug report in the Mac section.

Use vector QR codes instead!
Virtually every online QR code generator will make you one.
All. Problems. Gone.

Naja, ganz genau genommen ist es offenbar ein "RetourenDatamatrixCode (DmC)"…
Kannst du den nicht als Vektoren bei der Post exportieren?

So…
The quick and easy fix for good:

1. zoom in your placed QR code so that it's large enough on your display, the larger the better
2. take a screenshot of it (on Mac: cmd-shift-4 and drag the area)
3. upload the screenshot e.g. to vectorization.org
4. download the SVG and open it with Designer
5. merge all curves into one Curves object (having just one object is easier to handle)
6. copy the QR to your layout
7. apply K100 (because it will be rich black by default)
8. voilà, takes about a minute of work

Fair enough, the Scandit app reads it under "2D code".
