laposte is offering a new beaujard series ... read the soco post production of new series began in april - several CDs show dates earlier than 2011.7.1 ...
the ecopli 20gm has been found /wo phosphor (date unknown) ... and phosphor stains on euro blue. also see the 50g var above ... bent pins

MXU : one can either illustrate phosphor anomolies or manually define coordinates from point (0,0)
to calculate the shifts in MXP / MXD - eZgrader metrics software determines the relative position to 100% centred.
I am always discovering new phosphor anomolies ... here is a useful link ... for onscreen measurement device 1mm = 3.6 pixels
this clear-vue pixel ruler , is useful for 100% or scaled images ... for larger than normal scans, use ratio method.
note : glass blocks UV longwave light ... so optical scales must be transferred to plastic, to allow photography, or image capture.

- MXV defines the value and shade
- MXP or MXD defines the perforation or die-cut matrix (a,ab,ac ... n)
- MXU defines the phosphor, and flour-phos shade

photographing phosphors : to right are a positive and negative image of beaujard 0.01 euro . I have been experimenting with setups ... and captured using proscope and 10x lense , and a black-box with large uv-lamp inside ...

the focus of philatelists in france is based on chronology and tradition ... or, the patterns reflected in dbase arrays is sequential-numerical. in studying the beaujard definitives, I assume an outlook shown and demonstrated in Douglas Myall's masterwork - HB4 : "The Deegam Handbook". Dallay V9.17 is my prime source dbase ....
1.1 information is grouped by value rather than a catalog sequenced number. new variety or reprint data : date of emission, source (cyl or "presse" ) and definitive type: sheet (S), adhesive (SA) - (CD), or booklet (CA) is appended to this set. to achieve these new arrays, StampCat v9* offers a more advanced analysis and control of phila-objects thru time ... since the beaujard series, is active - this is a key point. *(9 image fields per record) Dallay v 9.11 does allow for personal vars to be recorded, with 1 image field and notes. these are added to collection reports...
2.1 no realtime analysis of phosphors types has been reported by the french philatelic press ... so I am actively building a library of uv-reactions for the yellow and white phosphor varieties ... illustrated maquettes are drawn for each var forming the basis of profiles ... phosphor maquettes are tipped in to an image cell of a given phila-object ... dbase fields can be overprinted on each phosphor-maquette as a stamp tag ... the same size as the phila-object (scalable) a pdf report is generated. profiles can be frozen as jpg using screen capture, or remain fluid within an active dbase ... the maquettes are jpg.
3.1 StampCat v9 generates stock pages, albums, profiles ... easily ! profiles are movable and used in print form on stock cards or album pages. also, realtime pdf reports can be quickly designed and saved. my collection progresses digitally ... any field information can be appended to a profile ... paper, plate var, shade, perforation... etc.
4.1 a cross-reference to Dallay is part of the .mdb ... I maintain reference and collection .mdbs ... as well, special focus .mdb for misperfs, miscuts and errors ... eventually part of a master file: SBJ v1.0 as items are fully sourced. information and jpegs can easily be transferred between .mdb files ... a lot of work, but a rewarding specialisation ...

the SP240 briat distribution shown demonstrates MXP for 200 items ... N or finely centred definitives are quite scarce for most issues ... less than 15% on average.

to summarise : 2 yellow bars were applied 15mm apart, sometimes continuously or as short bars with various settings. 3mm broad bar exist with 2mm bar either left or right. otherwise 2mm bandwidth was doubled. short bands : can touch the top or bottom margins or be more central in the diecut. insets : left or right exist ... as does a 3-bar variety, due to diecut left-shift. interupted bars : top or bottom; with weaker variations degrading from 50% to no phosphor... end of ink run. my sample size was 545 units.
in some CA issues, it appears the phos-cyl was applied first to paper. and the design cyl was overprinted, leaving only marginal phosphor bar in either left or right position. this effect is seen under LW, but impossible to capture photographically. the design ink appears diffused over the flour-phosphor ink, and the bandwidth is marginalized...
yellow flour-phosphor makes it harder to sight , or align the print run. (why royalpost abandoned it in 1995) the resin pigment was changed to bright blue in 2003. both UK and France now use toshiba sorting machines. so both colours work ... flour-phosphor inks vary in composition depending on the print process (litho or gravure) royalpost moved from inorganic compounds to organic resins, as the harder inorganics damaged the perforators.
since POs started issuing these self-adhesive products (SAP), collectors have sought solutions. and, philatelic suppliers have had to adjust album page designs ... a methodology follows :
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 (10,12 or 20 position MXDs)... 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 ... 3M tape with gum 2-sided will work.

- a constant var is repeated on subsequent prints, due to damage or retouch to the plate
- infrequent plate var can be caused by debris on the paper or cyl itself ... dust, insect, etc sometimes called a dry print. wrinkled paper : "accordion"
- doctor blade flaw : vertical line across the sheet ... dust or debris caught under the blade designed to moderate ink flow
- air bubble flaw : shows as a random dot on face of stamp ... irregular
