NEW SEAGULL SELECT VC-RP
RP Paper

New Seagull Select VC-RP
By using filters, it is possible to control the tones of the finished New Seagull Select VC-RP prints with this variable-contrast paper. With one type of paper, it is possible to handle a broad range of tones (#0~#5). New Seagull Select VC-RP is protected top and bottom by thin polyethylene, processing agents do not penetrate into the paper and wash times are dramatically shortened, making it a high-efficiency product. Also fast drying and excellent flatness make it suitable as general-purpose printing paper.

Safelights
15W bulbs should be used and Kodak OC or a Ilford 5902 Safelight filter are recommended. The safelight should be at least 1 .2 meter from the bed of the enlarger or developer. After exposure, be careful not to expose the emulsion side of the print to light.

Light source
In the case of VC-RP, a tungsten or halogen light source can be used. VC-RP is designed to be usable with a dichroic color head. A magenta light source produces a high contrast and a yellow light source produces low contrast. When using your own dichroic color head, do some testing before making a final decision on level of contrast. (Table 1 )

Exposure
Correct exposure times depend on the type of the light source of an enlarger and the characteristics of the negatives being printed. To get good final prints, test prints at various exposure levels should be made first.
Exposure times depend on the type of filter being used. For filters ranging from #0 to 3 1/2, prints can be made at almost the same exposure times. For #4~#5 filters, exposure times should be 1 .5 times that used for the other filters. When using a cool light head, adjustment must be made for the light source and the photographic paper by using adding a Kodak CC Filter-40Y.

Standard processing conditions
Process Processing temperature Processing time
Development 20+_ 0.5 C 60~90 sec.
Stop bath 15~25 C 5~15 sec.
Fixing 15~25 C 3~5 min.
Washing 15~25 C 5~10 min.
Drying 60~70C 30~60 sec.

Developer
For VC-RP printing paper, it is possible to use almost all commercially available developing solutions (D-72, etc.). The developing conditions depend on the chemicals and dilution level of the developer. Care should be taken to avoid over-developing which raises the fog and lowers contrast. VC-RP is applicable to both dish development and automatic development using an auto processor. 

Stop bath
For the stop bath, a solution of 1 .5% of glacial acetic acid is used. Time: 15 to 30 seconds.
Water 1 liter
Glacial acetic acid 15 ml

Fixer
Prepared fixer is recommended but, if you are preparing your own fixer, either use an acid hardening fixer containing sodium thiosulfate (hypo) or a rapid fixer containing ammonium thiosulfate. To make sure the prints will develop uniformly and not be affected by contaminants in the developer, the prints should be shaken in the developer. Keep the total fixing time to ten minutes or less. If the fixing time is too long, there is a risk that the tone balance will degrade.
 
Washing
The washing process can be finished in about five minutes by washing in water while stirring. The stirring should not be to strong since the corners of the prints may be damaged. If the washing is continued for too long a time, the surface of the prints may become rough.

PR-F RP paper Medium Glossy, smooth White Jet black
 
Drying
Drying is carried out using a hair dryer. It is also possible to dry the prints naturally if they can be placed in a location where there is sufficient air circulation.
High-temperature processing conditions New Seagull VC-RP has the properties which make it well-suited for high-speed processing.

Storage and treatment
Always store photographic paper in a cool, dry place. It is also effective to put a desiccant in a package which has been opened to keep the paper dry.
The paper should be used quickly after the package has been opened. Be careful to avoid exposing the paper for long periods to a safelight, or letting the emulsion side come into contact with fingers.
