FAQ
Which developers does Ronsein supply?
Ronsein supplies dedicated developers for PS plates, thermal CTP plates and CTCP plates, plus fountain solution, protective gum and plate wash.
Do I have to use Ronsein chemistry with Ronsein plates?
It is recommended for predictable results, but Ronsein plates also run on major brands such as Kodak developers. Using matched chemistry reduces scumming and extends plate life.
How should plate chemistry be stored and dosed?
Store at 15–25°C, follow the dilution and replenishment rates in the bulletin, and keep developer tanks covered to slow oxidation.
