Abstract An image deletion fluid for printing plates which use a silver image as an ink-receptive area. The deletion fluid comprises iodine and an effective excess of iodide ion, which form a triiodide complex, and a hydrophilic- matrix-forming agent. In a preferred embodiment, the deletion fluid further comprises an organic, preferably polar, solvent. The deletion fluid is applied to the surface of the plate, rubbed briefly and allowed to dry there, with no removal or rinsing away of the deletion fluid or by-products required.
