A coating applicator apparatus applies coating upon a sheet substrate that is being transported by a sheet-carrying cylinder in a rotary sheet fed printing press. The coating applicator apparatus comprises an applicator roller that is being supplied with liquid coating, that is being engaged into contact with the sheet substrate, that is transferring coating to the sheet substrate, and that is being sequentially engaged and separated from the sheet substrate with an actuation apparatus operating in concert with the press rotation creating a clearance between the application roller and sheet substrate to allow protruding sheet grippers to pass without interference.
