Are Errors Of This Type Common? I Can't Seem To Find Anything Similar To Maybe Get An Idea Of Value

Hi rAdelaide

You sure have the beginnings of a great and interesting collection. Your hunger for more stamp info is very refreshing. Thanks for posting your questions. It has been most interesting especially to see NSK's replies. We all benefit. Happy Days

Keep in mind that all printings on sheet margins printed from plates or cylinders that print the stamp will be found on each sheet. So, they tend to be common and will not add (much) value.

'Imprint,' most commonly, is used for the part of the marginal printing (sometimes tiny printing on the stamp itself) that identifies the printer. But each collecting area may have another definition. Such imprints often identify the position of the stamp. Again, specialists will be interested and may pay extra. But as a general rule, that extra value is limited.

Here is an example of an imprint of the year on a stamp, rather than on the sheet margin from the Isle of Man.



Sometimes, stamps are reprinted and the imprint changes. An example is where the reprint of above postage due labels had an 'A' added to the year of the issue.



Similarly, this can happen with imprints in the sheet margins. If the alternative print run is small, its imprint may become sought after, especially if it is the only manner in which to identify a reprint.

I shall leave it to the people with knowledge of Australian stamps to tell you what 'imprint' normally means and whether there are imprints to look out for.

Printers call both flat and cylinder printing devices plates.

As to these - poorly printed stamps won't be considered errors, I doubt these are anything.

In the UK, philatelically, the word cylinder is used for plates used for photogravure printings. Plate numbers are not known in GB philately when you talk about a photogravure stamp printed from cylindrical plates. They are called cylinder numbers. Plate is used for the flat photogravure plates.
