DYE HARDIn response to a recent column on inkjet printers (Sept. 23), John H. Fletcher of Marblehead, Mass., warns that some inks are not water-resistant and can cause trouble if used, say, to address envelopes. He's right, regarding older printers and some low-end current models. Early inkjets used water-soluble dye-based inks that tended to run when wet. These have largely been replaced by more stable black pigment inks. Industry leader Hewlett-Packard says the black inks used in all current DeskJet models except the 400 series are water-resistant pigments, though colors are less reliable in the rain. No.2 Canon Computer Systems says all of its BubbleJet inks, black and color, are water-resistant.
