Dark flaw in hair variety on booklet panes

Post by earsathome »

Hello All,
The scan attached shows the difference between this flaw on cylinder 17 and on cylinder 18 (UB25).

On cylinder 18 the flaw is much lighter and the dark spot behind the crown on
cylinder 17 has almost disappeared on cyl 18. This spot is not mentioned in my
(outdated) S.G. G.B. Spec cat vol 4 (sixth edition)

Can anyone explain this? Has it been retouched? I can find no mention of this in the catalogue.

The DFIH flaw is also listed under UB25b - unknown on one perforation type and unpriced on two perf types.
This (presumably) is on a non-cylinder pane. Does anyone have, or has anyone seen,
an example of this?

I have a fair number of panes with this variety on the ½p, 2½p and 3½p but they are
all on cylinder panes,

Any thoughts or help on this appreciated.
Regards to all
Ron.

This is not really an area I have delved in to any extent.

From my rummages at the BPMA (as Tony Walker puts it) I may have some information. See my article in the July /August newsletter.

In the 10p booklet with the 2p (cylinder B7) the negative was 155/0. In the 25p booklet with advert (cylinder b8) the negative was 181/0.

See attached.

Does this help?

Hi "Lennox"
Thanks for the swift response but I am afraid you have lost me completely

Being in Australia I will have to wait a while to get the July/August newsletter, but maybe that will clarify things for me a bit.

The negative figures 155/0 and 181/0 leave me confused, which shows how deeply I am not into printing methods etc.

Also the reference to the 10p booklet - can you expand on that as the DFIH was not there
(am I missing something)

Many thanks anyway and I await the newsletter with interest.
Regards
Ron
