Characteristics
Beautiful monochrome prints can be made simply from color and monochrome negatives using a printer that currently produces color prints. By changing the automatic printer setting to a channel setting, you can create beautiful neutral gray or sepia images in the same way as printing color negatives. This can be done using the color processing chemicals you are currently using.

Safety Light
Use in the dark as with color paper.Take care to avoid light that leaks from the enlarger and LED lights.
Developing and Processing Chemicals
Developing and processing can be done using chemicals for Kodak color papers, Agfa color papers, or Fuji color papers. Note that the colors will be slightly different for each processing chemical.
Processing can be implemented using a combination of this and color paper. However, where the color developer replenishment rate is 109 ml/m2 or less for a color processing chemical the processing amounts for the Hyper Seagull must be adjusted to 50% or below. Therefore, consult with the relevant manufacturers. Use processing chemicals in accordance with the users' manuals written by manufacturers for color paper processing chemicals.
Exposure
Prints can be made on the Hyper Seagull from both color and monochrome negatives. The Hyper Seagull is specified particularly for printing on minilab printers.
Standards when using minilab printers
(Printing is also possible on printers identical to those used in minilabs.)
When printing from color negatives
Set up a separate paper channel and adjust the sensitivity (approximately +2 using density key.) Note that a more natural red can be obtained using the portrait for example, by using the C+3 setting. (This may vary between machines, so test before use.)
When printing from monochrome negatives
Set up a separate paper channel and set the printer. Select a channel that has a high frequency of use for everyday prints, transfer the data from that channel and let it become the Hyper Seagull channel. Adjust the sensitivity of this channel (approximately +2 using density key.) There is no need to adjust the slope.
When using an enlarger (Sheet Printer)
(Use the following as a guideline since there will be differences in the kind of light source.)
When printing from color negatives
Test using a 20Y+20M CC filter.
The exposure time will vary between printers.
However, adjust after first using the time used for normal prints and increasing the density by approximately 20%.
When printing from monochrome negatives
There is no need to select a CC filter before printing. The exposure time will vary between printers. However, adjust after first using the time used for normal prints and increasing the density by approximately 20%.

Storage
Store any unopened packages of Hyper Seagull in a cool, dark place at 10 C (50 F) or less. If the paper is stored at high temperatures or humidities, its photographic characteristic may change. To avoid condensation forming when the paper is used, return it to room temperature by removing from the cool, dark place at least three hours before use.
When using the Hyper Seagull, avoid storing it in the magazine of the printer.
Latent Image Stability
When the time between printing and the development process is 12 hours or less, changes are within the allowable range. However, the more quickly latent images are processed the better.
Viewing Condition
Because dyes are used to create images on Hyper Seagull paper, note that the light used for inspecting will affect pure black images. When rendering or displaying prints, we recommend that you use a light source for daylight color rendering. (Note that ordinary fluorescent lights will increase the amount of red somewhat.)
