The marked-up image below assists in identifying the stamp where a particular flaw is located on the printed sheet.
The diagram is divided into nine sections and the number of the stamp on the sheet (from 1 to 42) with a flaw in a particular location is marked.
The map below shows the location by stamp number of many of the printing flaws on the 1d (1/-) Consumptive Homes stamp.
The number can be used in the table below the map to view the identified flaws on that stampp and on other stamps in that row.
The stamp image with that number can be seen with its flaw(s) from the following:
The two recesses in the top frame are the source of many printing flaws.
The following table will assist the use of the pooled numbers shown in the map above for the recesses.
It does not address the flaws in areas other than the two top recesses.
Left corner:
Left recess: 6, 11, 20, 23, 30, 31, 36.
Right recess:1, 4, 5, 10, 11, 12, 13, 21, 23, 29, 32, 34, 38, 41.
Right corner:
Left recess: 2, 12, 14, 34.
Right recess: 9, 14, 33.
Horizontal base of recess:
Left recess: 5, 6.
Right recess:1, 2, 3, 4, 5, 6, 9, 12.
Colour marks in recess:
Left recess: 6, 10, 13, 17, 19, 20, 21, 23, 24, 26, 27.
Right recess: , 6, 9, 10, 19, 21, 26, 33.
Note that some flaws might appear on some stamps but not on others. There are two possible reasons for this:
1. the problem identified could be an emerging one and a stamp being analysed came from a plate used later in the printing process.
This could be the case when a plate became worn and the frames cracked.
2. the problem is not really a flaw but a temporary issue with some dirt on the plate during the printing of some sheets.
The problem was then probably removed by the Stamp Printer wiping the plate clean during the printing process.
Some "flaws" also appear when too much ink has been applied by the printer or the plate had been used too long before being reinked.
