Support services and license agreement, description			On November 1, 2017 (“Effective Date”), we entered into a Support Services and License Agreement (“Agreement”) with Xeikon, N.V. (“Xeikon”), which is a division of the Flint Group headquartered in Luxembourg. Pursuant to the Agreement, we will provide Xeikon access to the Jetrion customer list. Access to the customer list will enable Xeikon to assume the relationship with the third-party outsourcing company that manufactures Jetrion printers for us and resell the printers to our current customer base. Xeikon will purchase Jetrion ink exclusively from us and resell to both our current customer base as well as new Xeikon inkjet customers. Also, we will cease sales of Jetrion products for four years after the Effective Date. We will receive cash consideration of $2 million in the first year followed by three annual volume-based payments that are tied to Xeikon’s ink purchases from us.
