Datasheet
New Seagull RC-M Premium Matte Paper
New Seagull RC-M is protected on both sides by thin polyethylene (Resin Protected). 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 and exceptional matte. It is a paper that can be used for both commercial-quality prints as well as news shots and will give you complete satisfaction. It is especially well-suited for highly enlarged exhibition prints.
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 RP-M is a highly sensitive paper and should not be exposed to light for long periods of time.Be careful with prints after they have been exposed to see that no further exposure takes place.
Exposure
To raise processing efficiency, the sensitivity of New Seagull RC-M 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 fall from grades #3 and #4 and in most cases cannot be raised much by increased exposure.

Developer
The use of a pre-formulated developer fluid is most convenient. Readily available developers for prints or dual-use developers of almost any type (D-72, etc. can be used.

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
Pre-formulated fixers are recommended for your convenience.
Fixers intended for use with widely available papers can be used. 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. When the fixing time is too long, there is a danger that tone gradation will deteriorate so it is necessary to be careful. Keep the total fixing time within 3 to 5 minutes. If you use a fast fixer, the fixing time drops to between 30 seconds and 3 minutes.
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
For drying, it is best to use a warm air dryer or dry the prints in a place where there is good air circulation, using natural drying. Ferro-type dryers should not be used.
Toning
New Seagull RC-M prints can be toned in a wide variety of ways. They are not easily damaged by contaminants and the intensity of the image is seldom lowered.
Use of selenium toners (Kodak F-24, etc.) are recommended.
Storage and Treatment
New Seagull RC-M has a very high level of photo-sensitivity. Therefore, it should be handled with care. Store the product at a low temperature in a proper place. Ideally, the container should contain a desiccant. 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 photo-sensitive gel come into contact with fingers. It is difficult to tell the front surface from the back surface of the paper so care should be taken when printing.
