Proper darkroom setup is crucial for achieving optimal results with Ilford Multigrade FB Classic paper.

2.1 Safelight Conditions

This paper is suitable for use with most common darkroom safelights equipped with an ILFORD 902 safelight filter or a similar amber/orange filter. The recommended maximum lamp واټtage is 15W, and the safelight should be positioned at least 1 meter (3 feet) from the paper. Always perform a safelight test to ensure no fogging occurs, especially if using a new safelight or working in an unfamiliar darkroom.

• Handle paper by the edges to avoid fingerprints, creases, or scratches on the emulsion surface.
• Store unused paper in its original packaging, sealed, in a cool, dry place away from direct light and chemical fumes.
• Avoid exposing paper to high temperatures or humidity, as this can affect its photographic properties.

3. عملیاتي لارښوونې

This section outlines the general steps for exposing and processing Ilford Multigrade FB Classic paper.

3.1 افشا کول

Ilford Multigrade FB Classic is a variable contrast paper, meaning its contrast can be controlled by using ILFORD MULTIGRADE filters or a variable contrast enlarger head.

• د آزموینې پټې: Always make test strips to determine the correct exposure time for your negative and desired print density.
• فلټرونه: Use ILFORD MULTIGRADE filters (grades 00-5) to adjust contrast. Lower numbers (00-1) yield softer contrast, while higher numbers (4-5) yield harder contrast.
• Enlarger Settings: Ensure your enlarger is properly focused and aligned.

3.2 Processing Steps

Process the paper using standard black and white photographic chemicals. Maintain consistent temperatures for all solutions.

1. پرمخ وړونکی: Immerse the exposed paper completely in a suitable black and white paper developer (e.g., ILFORD MULTIGRADE Developer). Agitate continuously for the first 10-15 seconds, then intermittently. Recommended development time is typically 60-120 seconds at 20°C (68°F), but refer to your developer's instructions.
2. Stop Bath: Transfer the print to an acid stop bath (e.g., ILFORD ILFOSTOP) for 10-30 seconds with agitation. This halts development and prolongs the life of the fixer.
3. فکسر: Place the print in a rapid fixer (e.g., ILFORD RAPID FIXER). Fixation time is usually 30-60 seconds for fibre-based papers, but consult the fixer's instructions. Ensure complete fixation to prevent staining and fading.
4. مینځل: Wash prints thoroughly to remove residual chemicals. For fibre-based papers, this is a critical step. Use a dedicated print washer or multiple changes of fresh water. A typical wash time for fibre-based papers is 30-60 minutes in running water, or using a hypo-clearing agent (e.g., ILFORD WASHAID) can reduce wash times significantly.
5. وچول: Dry prints face up on screens, or use a print dryer. Fibre-based papers tend to curl when dry; this can be mitigated by flattening techniques after drying.

4. ساتنه او پالنه

Proper care of your prints and unused paper ensures longevity and consistent quality.

• Print Storage: Store finished, dried prints in archival sleeves or boxes to protect them from dust, light, and environmental pollutants.
• کیمیاوي مدیریت: Always use fresh, properly mixed chemicals. Exhausted or contaminated chemicals can lead to poor print quality and staining.
• Darkroom Cleanliness: Keep your darkroom clean and free of dust, which can settle on negatives or paper during exposure.
