1st flame forgery booklet ...

I acquired this diecut forgery in HOLLAND.  it may source to the Mcanea m12 forgery booklet.   
to date, it has not appeared for sale anywhere ...  

readers should verify diecut singles postmarked 2001 +

2001,  Questa and Walsall issued m12 booklets ...  both are known missing phosphor.


A3B flour-phosphor ... dull and bright phosphors

Douglas Myall in DGR118 has offered new classification for dull phosphors that are appearing on several values : 1p 2p 5p 10p 20p 1£ 1st and 2nd values

Q. printers are varying, the sequencing cylinder?
I have tried to rationalize dull and bright phosphors

(as PUI , phosphor under ink)

IUP ,   Iriodin® under phosphor

my survey of values has revealed a spectrum of flour-phosphors :
very brite / brite A2B / dull A3B / very dull / none MFP


counter sheet forgery reported ...

  • this forgery shows wrong code MTIL ... (norphil blog)

  • the iriodin layer is shared with the recent birmingham red reported by Gerard Small in MBPC 45-6  note : oblique Y under bust in forgeries
  • scan shows halo head - common with 2nd 12TF, 1st 14TF...
  • matrix unknown ... booklet of 12 possible

14T birmingham red forgery ...

Gerard Small authored 45-6 Bookmark Journal article recently, that described this new forgery. 

swuv  - lwuv

the iriodin layer matches  with 2nd Mt pleasant blue ... I compare the layer to genuine : see below bust.

Gerard Small has remarked : same iriodin layer used in birmingham red forgery...

handling machin kiloware ... reviewed

  1. SAP "self-adhesive" security machins must be extracted from bundles or kiloware lots ...   only heptane will remove them successfully from paper.   neither water immersion nor philatelic hinge and gum removers have proven effective with 2009+ security cut machins... … from the machin forum this removal solution. I include a chemical analysis ... a.k.a. rubber cement thinner. ... used by commercial artists - no paper wrinkles on album pages 
  2. removal from paper : methodology

    1. removal : the adhesives can be successfully removed from paper using heptane* ... depending on the quantity of objects, this process will take 5mins to 1 hour or more... so setup as follows.... a basin of size is filled with heptane, and the stamps are saturated. after 5 mins, start removal from paper - and place face down on a glass sheet. wait 5 mins for excess heptane to evaporate , soon the stamps will become tacky ...
    2. replacement of adhesives : the glue will adhere to clear acetate but not vinyl sheets. as stock pages, I use binder photo album pages... the boards are covered by acetate sheets on 2 sides... within, I place a prepared 5x8 printed grid formed with StampCat9 reports. this acts a guide for placement of objects. the benefit, is the inserts can be varied - black sheet for scanning. the grid margins allow for inspection notes... I group by value and phosphor type ...
    3. alternately, I have used stockcard covers (clear acetate). this allows reconstruction of the various booklets as the matrices are sourced (T12, S6...) adhesives peel from acetate easily. album samples can be placed within stamp mounts, or first on cut-to-size clear acetate sheeting. stamp hinges do not adhere to vinyl, or acetate ...  rubber cement is universal ...
    • buy the 500ml can

  3. Water-activated machins : separate no-cancel machins on piece first from the kiloware ... though scarce, these can be separated from paper using UHU PRINZ hinge remover solution, applied to reverse side ... the stamps can soon be lifted from paper and placed within a "magic drying book" with vinyl and blotter pages... this method preserves gum and full phosphor

  1. the remaining used state machins can be separated best in a running water bath, with a overfllow topscreen ... the outflow eliminates transfer of soluable gum ( pvc or self-adhesive) and possible phosphor transfer to other machins ... place to dry in a "magic drying book" .... then, sort by face-value, prior to phosphor examination ..
  2.  there has been some question aired about loss of phosphor level and transfer of glue and phosphor to other machins during paper separation ....most used state stocks in dealer or collector hands have gone thru some water-immersion process ... some of these may demonstrate stronger or weaker phosphor reaction under inspection... but relative to modern printing methods, variations occur in phosphor application or absence thereof ... so classification of variant machins requires a list of all known possibilities as well as judgemental analysis of state of a machin's phosphor level ... even unused machins go thru this inspection ...
  3. on average only 3-5 % of all postally used machins are collectable ... heavy cancel examples ... these I discard as uncollectable ... don't waste your time ... build a quality collection !


the Mt Pleasant forgery ... reviewed

this is current royal mail red  M14L forgery.  
I have had queries from collectors, who are puzzled by what they see ...

LWUV : flour purple /w white bands
cameo speckled

since  my 9/15/15 post, 2 new vars have been uncovered in the MBPC journal 45-5
var2 - fishscale head - manchester red
var3 - head lettering multiplied, diadem irregular , brite blue flour bands

white head, 14 offset, spot on cheek

the forgers are now producing varied printings of same codes


2nd class blue ... no code var

these are dry prints - Iriodin cylinder not inked
first  reprted in 2009, they can be sourced by comparing the value settings
genuine and forgeries exist ...

n.b. - images must be digital, scanners do not see iriodin layer

security inks ...

machins have been printed with many different inks, and papers.  special pigments : Iriodin and rhodamine are examples ...

UV Fluorescent
These inks are normally invisible as printed but fluoresce under UV light. There are two types; single long wavelength (360 nm) and dual which fluoresces one color under short wavelength UVa (250 nm) and a different color under log wavelength UVc (360 nm). Typical UV fluorescent color inks include yellow, green, blue, orange, and red. These inks are often used in banknote printing. This ink is available for wet or dry offset, flexographic and gravure printing.

UV Phosphorescent inks also are used in different colors as modern presses operate at higher speeds, quality control is moderated by UV-curing process.   machins are 3 cylinder process - value / phosphor / iriodin layers ...

modern machin presses are using a variety of pigments and flourescent or  phosphorescent inks ...  the counterfeit machins exhibit their own group of flourescent pigments and inks.

in exploring our collections, we reveal some unusual UVa or UVc reactions on genuine and forgery items ...

LuminoChem  shows many inks under 258/365/980 nm lite sources.   raman spectroscopy uses varied light colors in analysis.   interesting addition to collecting experience.

luminescence ...

Douglas Myall describes printer inks as flour-phosphor ... Royal Mail has a standard for value inks, but not for tagging inks.  Phosphor triggers the SWUV Royal Mail scanners - but no afterglow on forgeries...

"there is no fixed standard for fluorescence, `as it is used for security and quality assurance purposes only and does not have to follow strict operational facing requirements"  - Dr. A. R. Lane, the British Philatelic Bulletin,

multi-printings can show shades of value ink, and or shades of flour-phosphor inks.
