Abstract
A printing device is described. The printing device comprises a fluid flow generator to cause a heating fluid to flow towards a curing zone that is downstream of a print zone in terms of an advance direction of the print medium. The printing device comprises an impingement device arranged upstream of the curing zone in terms of the heating fluid flow. The impingement device is to modify a flow rate of the heating fluid towards the curing zone along the advance direction.
Claims18
A printing device, comprising:
- a fluid flow generator to cause a heating fluid to flow towards a curing zone that is downstream of a print zone in terms of an advance direction of the print medium;
- and
- an impingement device arranged upstream of the curing zone in terms of the heating fluid flow, wherein the impingement device comprises a plurality of openings, each opening forming a nozzle, each nozzle to focus the flow of the heating fluid towards the curing zone,
- wherein the nozzles of the impingement device vary in size along the advance direction so as to modify a flow rate of the heating fluid towards the curing zone along the advance direction, the impingement device delivering a different flow rate to the print medium at a beginning of the curing zone than at an exit of the curing zone because of the variation in nozzle size.
1 more element
A printing device, comprising:
- a printing system in which a print fluid is disposed on a print medium, wherein the print fluid comprises a polymer component to coalesce when exposed to a heating fluid at a curing temperature;
- a curing system in which the print medium is exposed to a flow of a heating fluid at the curing temperature, the flow of the heating flow generated by a fluid flow generator;
- a transport system to move the print medium from the printing system to the curing system;
- wherein the curing system comprises an impingement system to modify a flow rate of the heating fluid towards the print medium along the advance direction, the impingement system to generate more than two different flow rate zones of heating fluid as the print medium moves along the advance direction such that relatively less heating fluid flow is directed to a point on the print medium as that point advances through the different flow rate zones;
- and
- wherein the impingement device comprises a perforated plate with a blank portion having no openings, a second portion having openings of a first size and a third portion having openings of a second, larger size, the blank portion being arranged first in the advance direction, followed by the second portion and then the third portion, the blank portion being as large or larger than the second portion in the advance direction.
