Here is a quote from a Linns Weekly article refering to Typography
Relief printing, like line-engraving, can cause distortions in the back of the stamp as the raised portions of the plate press into the paper.
The distortion in a relief stamp, however, results in a raised image on the back of the stamp rather than a depressed image on the back as in line engraving.
Another notable characteristic of relief-printed stamps is an excess of color around the edges of lines in the design.
This is caused as the ink is squeezed outward and over the vertical edge of the printing surface when pressure is applied by the ink roller.
When the paper is pressed against the relief, the excess ink at the edges of the design is transferred to the paper.
This halo effect is usually evident under strong magnification.
Relief-printed stamps usually do not have very fine lines because there is not enough material on the plate to support the fine lines,
and the rigor of the printing process would quickly degrade the plate.
Fine and intricate detail is virtually impossible with this method of printing.
