摘要:
A water base ink for ink-jet recording is provided, which makes it possible to secure a high recording quality with a sharp image area edge by avoiding any blurring even when recording is performed on regular paper and which has satisfactory purge restoration performance. Therefore, no bubble remains in an ink flow passage, and no discharge failure is caused. Further, the discharge operation never becomes unstable. In the water base ink for ink-jet recording, the surface tension is not less than 40 mN/m, and the amount of dissolved oxygen is not more than 4 mg/L.
摘要:
A water base ink for ink-jet recording contains an amine compound selected from the group consisting of N-n-butylethanolamine, 1,4-bis(3-aminopropyl)piperazine, benzylamine, and an amine compound represented by a specified structural formula, a surfactant having a specified structural formula, a coloring agent, and water. It is possible to obtain a satisfactory rub resistance and a high printing quality with a sharp outline without causing any feathering on a recorded image. Further, it is possible to obtain a long term nozzle discharge stability by suppressing any corrosion on a metal member of a discharge head unit of an ink-jet recording apparatus.
摘要:
An ink for ink-recording is provided, which makes it possible to reduce color bleed while suppressing even when recording is performed on regular paper. The ink for ink-jet recording contains water, a coloring agent, a water-soluble organic solvent, and a compound represented by the following general formula (1): wherein R represents a alkyl group having a number of carbons of 8 to 18, and x+y is not more than 10. A surface tension of the ink is controlled to 31 to 35 mN/m, which can reduce color bleed and feathering.
摘要:
A water-based ink for ink-jet recording and an ink-jet recording method allow the formation of sharp text and lines in high density black, and the formation of a high quality gradation image in which the graininess is reduced in a black image of a medium lightness to a high lightness (e.g., an achromatic image in dark gray to light gray) in ink-jet recording. The water-based ink combination for ink-jet recording comprises a black ink, and a color ink (A) and a color ink (B) that satisfy a color relationship of the following expression (I): about 120°≦|α-β|≦about 240° (I) wherein α is the hue angle of the color ink (A) and β is the hue angle of the color ink (B).
摘要:
A water-based ink set for ink-jet recording is provided which is capable of: reducing graininess in a low-density printed part without reducing the color reproduction range in red and magenta directions in a high-density printed part; extending the color reproduction range in the red direction; improving the vividness of the red color; and improving the light fastness and gas resistance. The water-based ink set for ink-jet recording includes a magenta dye ink and a red pigment ink. The magenta dye ink is a light magenta dye ink having a lightness (L*) of about 50 or more in the L*a*b* calorimetric system.
