REHOVOT, ISRAEL—  After filling for creditor protection in early July Landa Digital Printing is up for sale.  HP, Canon, Xerox among suitors as Landa struggles with mounting debt. The court has granted a 14-day freeze as buyers negotiate fire-sale prices. HP is believed to be the main party interested in acquiring Benny Landa’s digital printing company, Landa Digital Printing, which recently collapsed.   Landa Digital Printing has hired an investment bank to oversee the sale process. Companies who have  expressed interest in acquiring the company include Canon, Agfa, Fujifilm, Epson, Xerox, Brother, and Koenig & Bauer. Landa Digital developed, manufactured, and sold massive digital printers, each weighing about 30 tons. These printers use nano-pigment ink technology that injects tiny colour particles, enabling faster and higher-quality commercial printing. Each printer sells for $3–4 million, with installation adding several hundred thousand dollars more, along with significant ongoing costs for maintenance and for the special ink that Landa produces.
