Stopclock Pro - The Basics

Easy to use if you’re beginning yet versatile and powerful enough for professional printers, the legendary StopClock Professional really will save you time and paper. Using our F-Stop exposure system in conjunction with a built-in automatic test strip generator and ten exposure memories per channel, you can set up a complete printing sequence quickly and easily, often with reference to just a single test strip! Once the paper’s on the easel and the lights are switched off, making the print becomes a simple matter of pressing the start button and shading the relevant areas of the print. No times to remember, no fiddling with timer settings in the dark. The two channels make split-grade printing a breeze, and there’s even a special mode which effectively allows the exposure and contrast of variable contrast paper to be controlled separately. And if the base exposure is changed, the Stopclock recalculates all the burn-in exposures to maintain the correct density relationships! A special compensation mode alters exposure times to allow for the effects of “dry-down”, the change in apparent print brightness as the paper dries. It can also be used to compensate for the effects of toning.
