Bonsoir,

Le timbre vendu sur Delcampe est tr=C3=A8s probablement un trucage chimique=
, le rouge a =C3=A9t=C3=A9 "transform=C3=A9" en gris.=20

1) Un probl=C3=A8me d'essuyage aurait pu =C3=A9taler du bleu sur le rouge (=
mais on devrait avoir un m=C3=A9lange bleur/rouge), un papier bleut=C3=A9 e=
st plut=C3=B4t bon signe.=20
Exemple

=3D0


2) Sinon on peut avoir un probl=C3=A8me d'encrier o=C3=B9 le conducteur de =
presse met un peu de bleu dans le rouge comme l'encre est =C3=A9paisse =C3=
=A7a ne se m=C3=A9lange pas. C'est g=C3=A9n=C3=A9ralement assez rare.
Exemple tenant =C3=A0 normal

=3D0


3) Reste l'essai de couleur faussement dentel=C3=A9, il faut se m=C3=A9fier=
..

=C3=80 faire expertiser de pr=C3=A9f=C3=A9rence.

Bonne soir=C3=A9e.
