Why are you doing the QR codes in Photoshop or any other program?
Use InDesign >Object > Generate QR code…
No other program is needed.
Wow, didn't know that feature, thank you very much.
I'll try right away, if that solves my problem, i imagine it will, but still, does anyone have an idea what could have gone wrong before?
It just drives me mad, when software does things, i don't tell it to do and i don't know how to fix it...
The problem was caused by downsampling. The resolution was higher and you down sampled it with the wrong method, also you used a greyscale or cmyk or rgb image, in this case a 1-bit image would be the choice. But better is to use ID's QR functionality.
Thank you Willi, one more question,
You are saying, i down sampled with the wrong method. So what would be the right method? I just drag and dropped the file and placed using the placegun thingy.
Just asking for future projects, this particular problem will be solved by the internal QR-editor, i'm sure.
Boy that whole print-stuff is a whole new area for me, there's much to learn, so i am very grateful for people like you, who take their time to help a poor autodidact...
i may have used the scale tool as well, im not so sure...
When an image is resampled because it is scaled there are several methods in Photoshop. For images re the methods bicubic and bicubic sharper the best methods. But for similar thing like a QR code repeat pixel would be better.
Problem is, in InDesign, when you export PDFs and do the downsampling there, you have to select one method for all kind of images. But things like QR are not so often and with using a vector image (like the internal QR generator) you have solved that problem.
Danke nochmal für die Hilfe...
