How to use

Insert the KAISER 4431 format masks as a pair into the designated slot of the 4583 or 4493 compound negative carrier on your SYSTEM-V enlarger. Position the negative behind the mask, align edges as required for the desired framing, then secure the carrier in the enlarger. Proceed with normal focusing and exposure steps for enlarging or copying film. Handle the masks carefully to avoid scratches or fingerprints on the masking surfaces and negatives.

Usage recommendations

Use the masks on a clean, dust-free work surface and avoid excessive force when inserting or removing them from the carrier. For consistent results, verify alignment before each exposure and keep spare masks available if frequent format changes are required.
