Generally, before original ink purchased by a printing enterprise is printed on a printing machine, spot color ink needs to be prepared in advance according to the color design of a printed product, and the color gamut is expanded to print a spot color of a product manuscript design; or before gravure printing, flexo printing and other production, the original ink slurry is diluted and stirred uniformly so as to meet the printability requirement of a computer.

Generally, the blending of spot color ink and the dilution and uniform stirring of original ink slurry are completed by certain stirring equipment. In order to quickly detect whether the printing ink is uniformly mixed and stirred or not, the current printing enterprises often directly observe whether the color of the printing ink in the stirring barrel is consistent, whether transition exists or not or whether the printing ink is provided with a flower material or not through visual observation of human eyes; or randomly selecting a small amount of mixed ink, rubbing and spreading the mixed ink by using two paper patterns or performing sample printing and color spreading by using a color spreader, and then visually observing by human eyes to judge whether the ink is uniformly stirred or not.
