Knowledge / Errors / Introduction

Error: philatelic term for a deviation caused by an error (e.g. print, separation, gum)

Colour Error: deviation from the intended colour caused by an error (e.g. paper colour)

Mixed Up Prints: postage stamp with a different print as intended caused by an error (e.g. overprint)

Typ Error: deviation in the text caused by an error (e.g. hand postmark)

Design Error: deviation in the design caused by an error (e.g. design print)

Print on Blank Field: print on a perforated empty field caused by an error (e.g. burelage)

Print on Printed Label: caused by an error printed label (e.g. overprint)

Print Plate With Error: print from a caused by an error damaged printing form (e.g. overprint)

Albino Print: colourless instead coloured print caused by an er-
ror; only the embossed outlines and / or the perforation ist visible (e.g. design print)

Print on Reverse: postage stamp caused by an error with print on reverse instead on front (e.g. design print)

Inverted Print on Reverse: postage stamp caused by an error with inverted print on reverse instead on front (e.g. overprint)

Print on Two Sides: postage stamp caused by an error with the same print on front and on reverse (e.g. design print)

Missing Print: postage stamp caused by an error without print (e.g. overprint)

Partly Missing Print: postage stamp caused by an error with partly missing print (e.g. burelage)

Missing Separation: postage stamp caused by an error without separation at all sides (e.g. perforation)

Partly Missing Separation: postage stamp caused by an error with missing separation at one or more, but not at all four, sides (e.g. perforation)

Pair With Missing Separation in Between: pair caused by an error with missing separation in between (e.g. perforation)

With Print: postage stamp caused by an error with print (e.g. overprint)

Pair With Print and With Missing Print: pair one stamp caused by an error without print (e.g. embossing)

Diagonal Instead of Horizon-
tal Print: postage stamp with caused by an error 45 degrees rotated horizontal print (e.g. overprint)

Vertical Instead of Horizontal Print: postage stamp with caused by an error 90 degrees rotated horizontal print (e.g. overprint)

Inverted Second Print: postage stamp caused by an error with 180 degrees rotated horizontal print (e.g. second overprint)

Partly Inverted Print: multicolour postage stamp caused by an error with partly 180 degrees rotated print (e.g. design print)

Pair One Stamp With Inverted Print: pair one stamp caused by an error with 180 degrees rotated print (e.g. overprint)

Pair With Inverted Print and With Missing Print: pair one stamp caused by an error with 180 degrees rotated print and the other without print (e.g. overprint)

Diagonal Inverted Print: postage stamp with caused by an error 180 degrees rotated diagonal print (e.g. overprint)

Double Print: postage stamp caused by an error with twice print (e.g. design print)

Double Separation: postage stamp caused by an error with twice separation at all sides (e.g. perforation)

Partly Double Print: postage stamp caused by an error printed twice one partly missing (e.g. overprint)

Partly Double Separation: postage stamp caused by an error with twice separation at one or more, but not at all four, sides (e.g. perforation)

Pair One Stamp With Partly Double Print: multicolour pair one stamp caused by an error with partly twice print (e.g. design print)

Pair With Double Print and With Missing Print: pair one stamp caused by an error printed twice and the other without print (e.g. overprint)

Double Print One Albino: postage stamp caused by an error printed twice one colourless (e.g. overprint)

Double Print One Diagonal: postage stamp caused by an error printed twice one 45 degrees rotated (e.g. overprint)

Double Print One Vertical: postage stamp caused by an error printed twice one 90 degrees rotated (e.g. overprint)

Double Print One Inverted: postage stamp caused by an error printed twice one 180 degrees rotated (e.g. overprint)

Pair One Stamp With Double Print One Inverted: pair one stamp caused by an error with simple print and the other twice printed one 180 degrees rotated (e.g. overprint)

Double Print Both Inverted: postage stamp caused by an error printed twice both 180 degrees rotated (e.g. overprint)

Double Print With 2 Different Prints: postage stamp caused by an error printed with two different prints (e.g. overprint)

Separation Size Error: postage stamp caused by an error with a different number of separation elements (e.g. rouletting)

Partly Separation Size Error: postage stamp caused by an error with a different number of separation elements at one or more, but not at all four, sides (e.g. perforation)

Print Space Error: deviation from the intended space between two parts of the print caused by an error (e.g. design print)

Print Space Error: deviation from the intended space between two prints caused by an error (e.g. design print)

Pseudo Error: during the printing of a postage stamp intentional produced supposed error (e.g. double overprint)

Size Difference: caused by an error deviation from the intended size (e.g. sheet)
