Sprint End Run Print Brightener Solution, for Increasing the Brilliance of a Black & White Print's Highlights

END RUN Print Brightener solution changes the invisible ultra-violet (UV) light reflected from a print surface into visible white light, increasing the total visible reflectance and brilliance of the print's whites without bleaching. The same brightening agent is manufactured into some printing papers, but can be lost during processing and washing. END RUN Print Brightening solution adds to or replaces these built-in brighteners after the final water wash. Print brightening can increase the archival permanence of prints by shielding them from UV light which might otherwise cause image and paper deterioration. Print brightening will make some warm-tone papers appear cooler in color.
