New Seagull RC is protected on both top and bottom by thin polyethylene. It is a high-sensitivity, jet-black tone, general-use enlarging paper.
From brilliant highlights to deep blacks, it has a rich range of tones. Since processing agents do not penetrate into the paper, wash times are dramatically shortened, making it a highly efficient product.
The surface of the product has a high degree of smoothness and there is virtually no dimensional distortion, making it an easy-to-use paper.
The RC paper is available in glossy (F), Matte, and luster (R) finishes and the following sizes.
New Seagull RP-C will be available in the following sizes and quantities:

New Seagull RC-R (Resin-Coated Luster Paper)
New Seagull RC is protected top and bottom by thin polyethylene (Resin-Coated). It is a high-sensitivity, jet black tone, general-use enlarging paper. From brilliant highlights to deep blacks, it has a rich range of tones. Since processing agents do not penetrate into the paper, wash times are dramatically shortened, making it a high-efficiency product. The surface of the product has a high degree of smoothness and there is virtually no dimensional distortion, making it an easy-to-use paper.
Safelight
For general-use enlargers with yellow-green filters, 15W bulbs should be used and the safelight should be at least one meter from the enlarger. New Seagull RC is a very high-sensitive paper and should not be exposed more than 10 minutes.
Be careful with prints after they have been exposed.
Exposure
To raise processing efficiency, the sensitivity of New Seagull RC has been raised to a very high level. The maximum level of sensitivity gets lower as the grade number rises; #2, #3, and #4 have progressively lower maximum sensitivity levels. #3 is about 70% of #2 in sensitivity level. #4 is about 50% of #3 in sensitivity level.
For most printing paper, the density of the negative begins to raised much by increased exposure.

Developer
For New Seagull RC paper, it is possible to use almost all commercially available developers or use standard formulations (D-72, etc.) without changing the performance of the product.
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 white stirring. The stirring should not be too 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.
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.
Ferro-type dryers cannot be used.

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.
