Look for the Arches 88 watermark on the sheet you bought to verify you have the correct paper. Some people are sold Arches 88 but the sales clerks don’t really know the product and are selling people watercolor paper. Watercolor paper will not work. It will bloom. Use the new DASS Premium Transfer Film.The receiving paper MUST be well soaked with Purell on both sides. If it is not fully worked into the paper it will bloom with the white dust. If your hands touch the Purell it will liquefy and cause the bloom. Print at 1440 dpi (600 dpi on the HP) using a watercolor paper profile. This will cause the printer to use the matte black. Heat causes the Purell to liquefy which results in the white bloom. After the transfer is done leave the paper on the surface you used to do the transfer. Do not move it to drying rack. Heat of any kind is the enemy of this process. Also try storing the Purell in a refrigerator. The ideal room temperature to work in is 75 degrees. Also try applying the Purell to both sides of the paper then letting it dry. After it is dry reapply the Purell. The buffers in some paper can cause the white spots so the second application of Purell may solve the problem.
