UK Gold Horizon Label 1LG
 
Horizon Label is stamp/label that are oversized Machins measuring 59 x 64.5 mm and printed in pale ‘gold’ with full bleed (no white frame around design). It was introduced in June 2009.
 
The Queen’s Head was produced using a wavy line ROYAL MAIL pattern printed in micro text pale ‘gold’.
 
The complete label was overprinted with a repeating iridescent wavy line ROYAL MAIL pattern for the background while the head itself had a different pattern.
 
These labels were not printed with phosphor lines and they are self-adhesive paper.

The revised versions were introduced on 23 August 2010 to address problem with operational difficulties by clerk when feeding the second label after the first one has been removed.

Royal Mail Accounting Codes - September 2011

The Horizon software was changed in late September 2011 to classify the VAT rating of posted items. As a consequence the Machin Horizon labels were printed with two codes indicating the accounting classification and can be found at the end of the lines as follows :
 

Line on Label	Indicator Type
Royal Mail	Accounting Code
POSTAGE PAID UK	VAT rating code

‘Accounting codes' are solely for easy identification of the VAT rate or product combination for each label, where a subsequent refund has to be made, ensuring any VAT is accounted for correctly.
