Wilding papers

Post by larry6mac »

During the curfew here in Canada I have been going over my Wilding 'castle's' and was wondering if the same principles apply to the cream paper s of the Waterlow issue that appear in the wilding definitives. Does the long wave ultraviolet lamp show the same results.

Hi there Larry 2259,
The first printings of the high-value castles was made by Waterlow in 1955 using the Edward crown watermarked paper and was also used by De La Rue up to 1959 when the watermark was changed to the multiple crown design, and according to the book all Edward crown watermarks should be on a cream paper, consequently the same principle applies when using a long wave ultraviolet lamp designed for stamp detection purposes.
Hoping this answers your query. WM.

Hiya LM, any chance of posting a scan of this £1 whiter variety of paper that you have discovered, alongside a cream one front & reverse for comparison ?
This is just an example of a frontal view showing the difference between cream and whiter papers under long wave UV, in this case it concerns the 4d Guernsey plain, as according to the SG specialised catalogue the cream paper does not exist.

With a view of the same stamps in the visible spectrum, even then the cream paper appears to have a more yellowish tint when comparing it to the whiter pair.

According to the experts the whiter paper was produced by means of filtering the water obtained from the local river, but in my opinion these cream papers had nothing to do with filtration and was created by the use of chemical oxidation whilst the paper was still in the pulp stage, in order to nullify fluorescent contaminants that had been discovered.

Mr. Frank Walton RDP FRPSL made mention to variations in some of the papers used to print Wilding stamps in my topic " The multiple crown Wilding stamp papers 2 " on the 6th of May 2020 and I made further comments at a later date on the 12th of November appertaining to the use of additives.
Both of which gives account of colour variations to be found, also at the time that the Edward crown watermarked papers were being produced at the Stowford papermill, Ivybridge, the water from the river Erme was not filtered, giving further colour variations to the papers produced at that time.

Is this particular stamp a white paper variety or a lighter cream paper ?

Is there any difference in the visible spectrum as opposed to the ultraviolet attachments ?

Another good comparison test would be to look at the Bradbury Wilkinson printings from 1963 - 1968 under ultraviolet, as they were printed on a whiter paper as against the original cream version.

Based on the above mentioned facts and the attachments that you have submitted Larry, it's quite possible that you have come across a lighter cream paper unlike the differences found between the 4d Guernsey stamps.

Perhaps other members may wish to make their comments on the observations relating to the differentials found !

Exit stage left. WM.
