Is This An Error On The Stamp ?

Hello and have a great day to all of you

I was wondering if any of these are an error
The white stripe on this one



And the white dotish thing on this one



I dont know if these are wortg something or not or if these things are giving or taking from its value . So if you can help me even a little bit it will be appreciated .

Nothing in Michel regarding the German stamp. It looks like the white line was applied while the letter and stamp were in the mail stream. The second "E" of DEUTSCHE is slightly faded and in line with the white line. Maybe you can provide a close up? In any case it would not be an error but a freak or an oddity.

I agree with Germania on the German stamp. White, usually, is not an ink colour used to print stamps. That leaves "foreign matter" as an explanation. This leaves part of the stamp unprinted. But the white line is interrupted. That is a strange shaped foreign object or two foreign objects in perfect alignment. Also, it looks like the white line is visible at the bottom of the stamp, being in a slightly different colour than the paper. As Germania writes, some white coding may have been applied for use by a sorting machines.

For the German stamp, Stampcoll did not provide us enough information, which would likely actually answer their own question. Specifically, is ink missing or covered up? Easily determined by holding the stamp to a strong light. Identification of EFOs on used stamp has an added level of complexity.

As far as I understood I need to provide close ups and one with a good light behind it. #305;f I understood it correctly I think these will do the job

Over the years many countries have printed routing marks on mail, often using reactive inks to enable machine processing. These "ink" spots are often seen on British stamps.

The closeup above reminds me of these marks.

It is clear from the back-lit image that the stamp inking is complete and the white lines are added. Being on a used stamp, I would agree these are processing marks of some sort.

Hi,

Six flaws are known for this particular stamp.

Here are two of them. Position 6 and 18 (Not all sheet).
