At the professional corner of the HP booth HP showed their solution for the professional photographer; the HP Designjet Z3100 photo printer. According to the spokesman of HP the company has listened to what professional photographers really want with these large format printers. The new HP Z3100 printer features a 12 ink solution, including 4 black inks for the highest possible quality. The 12 inks have been engineered to meet the needs of the most demanding professional photographers. Thanks to the HP Gloss Enhancer the HP Designjet Z3100 photo printer delivers excellent gloss uniformity across the whole tonal range, eliminating bronzing and enabling true black-and-white printing performed with 4 black inks to avoid metamerism.
