摘要： A computer-implemented method (100) for determining printing parameter values (1) of an inkjet printing device (2) for printing a pattern on a surface (3) of a spectacle lens substrate (4) comprising a curved surface, the inkjet printing device (2) including a printhead (5) as one single component with a plurality of printing nozzles (6, 6a, 6b, 6c) is provided. The method comprises: grouping the plurality of printing nozzles (6, 6a, 6b, 6c) into at least two printing nozzle groups (10a, 10b, 10c, 10d, 10e), and individually determining a printing parameter value (1) for at least one adjustable printing parameter (7, 7a, 7b, 7c, 7d, 7e, 7f) of each printing nozzle group (10a, 10b, 10c, 10d, 10e), wherein the printhead (5) and the spectacle lens substrate (4) are configured to be not tilted.
In addition, a data processing system (200), a computer program, a non-transitory computer-readable storage medium, a method for inkjet printing, and an inkjet printing device (2) are provided.

摘要： A print component includes at least one data pad to receive data segments. Each data segment comprises a number of segment bits, the number of segment bits including a fire pulse group comprising a number of fire pulse group bits, and the number of segment bits being at least equal to the number of fire pulse group bits. The print component includes at least one clock pad to receive an intermittent clock signal and a fluid actuator array corresponding to a liquid type and to the data pad. The fluidic actuator array has a corresponding array of memory elements to serially receive a data segment from the data pad each time the intermittent clock signal is present on the at least one clock pad and to store at least the fire pulse group bits.

摘要： The present invention relates to an enclosure system which enables a worker to maintain equipment inside an enclosure while keeping a gas atmosphere inside the enclosure. To this end, an enclosure system of the present invention comprises: a process unit moving chamber including a first maintenance opening hole through which one side portion of a process unit is exposed and a second maintenance opening hole through which the other side portion of the process unit is exposed, the process unit moving chamber moving integrally with the process unit; a management unit moving chamber including a management opening hole through which a management portion of a management unit is exposed, and moving integrally with the management unit; and a fixed chamber connected to a door installed at one side wall part of an enclosure to form a predetermined space, the fixed chamber including a docking opening hole extending toward the inside of the enclosure, wherein through movement of the process unit and the management unit, the process unit moving chamber and the management unit moving chamber come in close contact with each other to allow the first maintenance opening hole and the management opening hole to communicate with each other, the process unit moving chamber and the fixed chamber come in close contact to allow the second maintenance opening hole and the docking opening hole to communicate with each other, and thus the process unit moving chamber, the management unit moving chamber, and the fixed chamber form one sealed space.

摘要： The present invention addresses the technical problem of providing a method for quickly and accurately processing the volume and position of an ink drop.
In order to solve the above problem, a pad for measuring the volumes and positions of inkjet drops that are sprayed in a constant volume from nozzles of a head of an inkjet device and drop onto the pad is characterized in that: a pattern part is formed, the pattern part including a plurality of groove portions arranged at pitch intervals corresponding to the pitch intervals of a plurality of head nozzles, and wall portions formed between the groove portions; the groove portions are formed long enough to encompass all of the heads to be measured that are present on the same line; and the groove portions are uniformly formed so as to have the same cross-section throughout the entire length thereof.
Due to the above configuration, the present invention has the advantage that the volumes and positions of ink drops can be accurately measured using the pad to a precision of 1% or less much more simply and quickly in an inkjet printer device than with existing techniques that use a strobe.
