Luis, Does everybody know how to tell an offset-litho version from the typography version??? In the case of the JSM series when the paper is coated [tizado] it is rather easy. But when only matt paper is around (mate Naciónal, mate importado) it is a lot more difficult. In the case of the 50c Puma the easy answer is in the face of the animal - white around the nose is typography, lot of lines is offset-litho. [color=#800000]Alguien sabe como distinguir la version offset de la version tipografica???? En el caso de las series de JSM cuando el papel es tizado es bastante simple. Pero cuando el en cuestion es mate ( Mate Naciónal o importado ) es muchisimo mas dicil. En el caso del puma 50c hay una manera sencilla de distinguirlos mirando atentamente la cara del animal. si hay blanco alrededor de la nariz es tipografiado, y cuando tiene muchas lineas es offset[/color] The 50c Puma in offset-litho:

Luis, At long last I have got a stamp very similar to the one you showed! Indeed the stamp has been printed in typography but the superfluous ink on the cylinder - it looks like this stamp has been printed on the reel-fed rotary and not the sheet-fed press - might have been wiped off by a brush and not a doctor's blade. In typography the to be printed parts of the design are sticking out so any doctor's blade can only be desctructive. But de Casa de Moneda has a long tradition of deforming the design of typographed stamps! How come the Post Office has accepted that for such a long time! The "normal" typographed Puma:
the "striped" [rayado] typographed Puma:
The discolouring of this stamp - it is rather orange than yellow-ochre - has probably been caused by chemical sources or overdisposure to sunlight??? |
