37¢ Flag Scott 3632A Question

I have two samples.

One has the uneven tagging and the other has solid appearance tagging.

The uneven tagged one under longwave has a lighter red than most of the 37¢ Flags. The red stripes usually are dark under UV. I believe this is the luminescent ink variety.

Scott makes the comment that yellow ink on plate S3333 causes it to glow orange and plat S4444 was printed with and without luminescent yellow. I do not know the plate but just confirming that what I call light red is the luminescent ink variety. Hans van Gils's guide calls it Lum. Red Ink. I am just puzzled about the orange but I admit I am not good at judging shades.

Hi Angore. First, I do not believe this stamp uses luminescent ink. PNC3 calls it phosphorescent, and as far as I can tell the only plate that does not shine orange is S2222.
Both plates S3333 and S4444 were tagged both ways, "uneven" tagging and "smooth" tagging. In other words on a single stamp one can not tell what plate it is from by looking at the tagging.

I was just quoting Scott on their statements regarding this issue but I need to recheck tonight when I get home. As I said, one appears "dead" (dark red) and other is brighter but not really orange to me. Orange (unlike something like pigeon blood red) is such an obviously color so maybe there is something else is going on.

I need to get my camera setup this weekend to take some decent pics.

This is a snap shot from Gil's guide. I wish someone had a picture of one with and without to see the difference visually.,



From PNC3:
S1111 is know only with Solid Tagging. S2222 was found in February, 2004. Plate S3333 was found with both Solid and Mottled Tagging in mid June, 2004. S4444 was reported in November, 2004 and has both Solid and Mottled Tagging. Both S3333 and S4444 with Mottled Tagging have Red Stripes on the Flag that glow either Orange or a Bright Orange under Longwave UV light. The stripes are dead on the solid tagged stamps when viewed under UV light. More reports are solicited on the tagging varieties. Plate # S1111 with Mottled Tagging apparently does not exist.

I wouldn't call it orange. Orange-ish red.




It is luminescent ink, not phosphorescent ink, and I have never heard of the S1111 giving the orange-ish glown only some examples of the S3333 and S4444.

Another issue that has some that give the orange-ish glow is the 3636c on some examples of the S4444, S5555 and S6666.

Trouble is, some glow more than others.

I have a complete booklet of 3636c S1111 but no orange glow. I am convinced mine are not luminescent variety after checking a number of stamps. From Hans guide, the red stripes can either be dead or appear light red but not the same as the orange glow.

He sent me this image. I need to find an actual stamp for reference.



I finished sorting all on 37¢ Flag stamps and now need to decide what spaces to put in album. This group has varieties not listed (meaning no minor numbers) for the variations in tagging (solid, solid grainy, mottled/uneven) and Scott does not list that 3636c booklet is serp 11.4 rather than 11.5. They round too much anyway (nearest quarter in many cases).

Durland was not much help either in this set.

He has many others. It has more than I ever wanted to know and more than PNC3.
