摘要:
The present invention provides an inkjet printer and an inkjet printing method, which enable an ink that overflowed to the outside from the edge of a printing medium to be fully absorbed by a platen. More specifically, the present invention provides an inkjet printer, including a platen, which absorbs a pigment ink that overflows to the outside of a printing medium when edgeless printing is carried out on the printing medium by using an ink that employs a pigment as a colorant, moving a printing head along a guide shaft, and ejecting the pigment ink from the printing head, and also an inkjet printing method, wherein the platen is impregnated with a humecant, a base, and the like.
摘要:
An ink composition includes at least a pigment, a humectant, and water in from 10 to 60% by weight to the total amount of ink. The humectant is a mixture of (A) at least one compound selected from glycerin, 1,2,6-hexanetriol, diethylene glycol, triethylene glycol, tetraethylene glycol, and dipropylene glycol; (B) either trimethylol propane or trimethylol ethane, or a mixture thereof; and (C) at least one compound selected from betaines, saccharides, and ureas and having a molecular weight in the range of from 100 to 200, at a content weight ratio of (A):(B):(C) of 1.0:0.1 to 1.0:1.0 to 3.5.
摘要:

摘要:
An electronic thermometer includes a hollow probe provided at its longitudinal tip with a temperature measuring unit having a temperature sensor for sensing a temperature, electrodes neighboring to the temperature sensor and arranged in the hollow of the probe, and a determining unit for determining whether temperature measuring unit is in appropriate contact with a measurement target portion of a user or not, based on a change in electrostatic capacity sensed using the electrodes.
