Be the first to review this product


Fotospeed SLT20 Selenium Toner is a liquid toner which is supplied in a single part concentrate.



It is specifically designed for the toning of Fibre and Resin Coated B&W papers to produce a wide range of subtle warm purple black tones or at higher dilutions for Archival Permanence techniques.



The shade of the tone is adjusted by dilution and the length of time the print is allowed to stay in the working solution. The longer it remains in the solution the more toned it becomes.



Resin coated papers can be slow to react with selenium, particularly the variable contrast papers. Papers with chlorobromide emulsions are the exception and will produce very effective results.

Fotospeed SLT20 Selenium Toner is a liquid toner which is supplied in a single part concentrate.

It is specifically designed for the toning of Fibre and Resin Coated B&W papers to produce a wide range of subtle warm purple black tones or at higher dilutions for Archival Permanence techniques.

The shade of the tone is adjusted by dilution and the length of time the print is allowed to stay in the working solution. The longer it remains in the solution the more toned it becomes.

Resin coated papers can be slow to react with selenium, particularly the variable contrast papers. Papers with chlorobromide emulsions are the exception and will produce very effective results.

 

MIXING INSTRUCTIONS: Dilute from 1+3 to 1+12 with water to make the volume of working solution required depending on the speed and depth of tone required and the type of paper to be toned. The whole procedure can be done under normal room or daylight conditions. Having selected the print to be toned ensure that it has been fully fixed and washed. In the case of dry prints first soak them in water to ensure that the emulsion is fully wet. This takes about one minute. Now put the print into the dish of toner working solution and agitate it gently. The toning time takes anything from 1 minute to 15 minutes depending on the shade of tone required. Now fully wash the print for 5 minutes for resin coated papers and for 15 minutes for fibre based papers. Dry in the normal manner. Resin coated papers can be slow to react with selenium toner. With this type of paper mix the working solution at the lower dilution (1+3) and use a temperature of 25C if necessary to assist the process.

ARCHIVAL PERMANENCE TECHNIQUE: Dilute 1+39 with water to make the volume of working solution required. Follow the instructions as above for toning in mixing instructions. Archival Permanence can be achieved with no appreciable change to the original tone of the print.

STORAGE: The working solution will keep for 2 months in a bottle and for at least a week in the open dish. Concentrates will keep for at least one year in the original bottle.
