I've no idea what's the problem. PDF417 are bw images with G4 encoding.

Subject: [iText-questions] PDF417 has grey spots when printed

Hi,

 

I've got a problem printing PDF417 barcode on the label. It looks contrast black & white on the screen but has some grey spots when printed on laser or thermal printer. There are various shades of grey visible on about 20% of barcode placed sporadically, but the pattern is repeatable between printouts. I'm using  the code from examples-133, Adobe5, 6, similar results on different computers/printers.

What do I do wrong? is that anything to do with image transparency?

 

Any ideas would be greatly appreciated!

Thanks,

Alex
