Kentmere Centennial Gelatine Chloride Printing Out Paper

Printing Out Papers were originally manufactured in Europe by Johann Baptist Obernetter of Munich in 1884 and Raphael Eduard Julius Liesegang of Düsseldorf in 1886 making gelatine printing-out papers one of the longest-living photographic products, being marketed continuously for well over one hundred years.

In the mid-1890’s many manufacturers produced POP and it was for many decades the standard printing papers in the industry.

Kentmere Centennial POP is a silver chloride, gelatine emulsion coated onto a double weight fibre base paper. The surface finish is glossy with a very fine lustre. The emulsion contains an excess of silver nitrate and will print-out with great intensity. No developer is required; the image is formed directly by the action of light on the paper during exposure. The colour of the image may be variously described as aubergine, purple, blood-red, rust-red or plum red. The colour of the final processed image can range from orange-brown, gold through light-yellow for images which are merely fixed, to a range of chocolate brown, purple-brown and lighter golds depending upon the toning of the image.

Split-back printing frames are customarily used as the progress of the image can be seen without disturbing the registration of the negative and the POP, click HERE for more information.

Kentmere Centennial POP is sensitive only to blue and ultra-violet light and is very slow so its suitable only for contact printing and usually outdoors in daylight. Split-back printing frames are customarily used as the progress of the image can be seen without disturbing the registration of the negative and the POP. We usually have a few such frames in stock at reasonable prices, although they are not strictly necessary and a piece of heavy glass to hold the neg and POP flat will suffice to get you started. Wash the print and fix. Plain old Hypo (sodium thiosulphate) is used as the fixer, (today’s rapid fixers based on ammonium thiosulphate are not recommended as they bleach the image) so you’ll need to get some of this, its available in our webshop.
