Reliable fixer powder
The KY-338 fixer works perfectly in tandem with the developer. It clears the film rapidly and ensures archival quality. No issues with fading or incomplete fixing after several batches.

Consistent quality batch after batch
I have been using Keyi chemicals for my pre-press work for over a year. The consistency between different batches is remarkable. It makes troubleshooting much easier when the chemistry is reliable.

Perfect for rapid processing lines
Our lab runs a tight schedule, and this high-temperature formula saves us significant time. The results are sharp and clean. We have reordered this product three times already.

Good value, mixes easily
The powder dissolves quickly in water without leaving much residue. I use it for film processing in my darkroom. The only reason for 4 stars instead of 5 is that the packaging could be more resealable for long-term storage.

Solid performance for the price
Compared to other brands, Keyi offers great performance at a lower cost point. The developer activity remains stable over many cycles. Just ensure you monitor the temperature closely for best results.

Excellent for high-volume plate making
We switched to the Keyi KY1000 developer for our offset printing plates last month. The development speed is impressive even at higher temperatures, and the contrast is very consistent. Highly recommended for commercial shops.
Q: Does this product come with a measuring scoop?
A: Yes, each package includes a standardized measuring scoop to help you achieve the correct mixing ratio accurately.
Q: What is the recommended dilution ratio for the KY1000 developer?
A: The standard dilution ratio is 1 part powder to 4 parts water by weight, but please refer to the specific instruction sheet included in the package for your specific application type.
Q: How long does the working solution last once mixed?
A: Once mixed, the solution typically retains optimal activity for 7 to 10 days if stored in a sealed, light-proof container at room temperature. Capacity depends on the volume of film or plates processed.
Q: Is special safety equipment required when handling these powders?
A: Yes, we recommend wearing gloves, safety goggles, and a dust mask when mixing the powder to prevent irritation. Always work in a well-ventilated area.
Q: Can this be used for color film processing?
A: No, the Keyi KY1000 and KY-338 are formulated specifically for black and white film processing and plate making. They are not suitable for C-41 or E-6 color processes.
