A color patch that was printed based on a plurality of test ink quantity sets prepared in advance is image inputted; a graininess index is calculated based on the inputted color patch image; the graininess index on a printing medium obtained when printing is performed according to an arbitrary ink quantity set is predicted based on a graininess profile produced based on the corresponding relationship between the test ink quantity set and the graininess index.

Apparatus and methods for delivering liquid color to a plastic resin processing machine include a scale for weighing a container of liquid color, a pump for removing liquid color from the container, controller for actuating pushers in the pump in a sequence whereby a first pusher is displaced to squeeze the delivery tube while a second and third pusher are not displaced thereby permitting liquid color to flow through the tube from the supply to a first position of tube squeezing, whereupon a second pusher is displaced to squeeze the tube and substantially trapped liquid color in the tube at the first and second position of tube squeezing, whereupon the first pusher permits liquid color to flow through the tube pass the first position of tube squeezing and the third pusher squeezes the tube and thereby forces at least a portion of the trapped liquid color material through the tube pass the first position of tube squeezing thereby supplying liquid color to the plastic resin processing machine at a predetermined rate according to a selected recipe to produce plastic parts having desired characteristics.

The invention relates to printing and dyeing ink for a direct inkjet textile and a preparation method thereof, the printing and dyeing ink comprises reactive dye, N-methyl-2-pyrrolidone, ethylene glycol monomethyl ether, isopropanol, propanetriol, triethanolamine and deionized water, the printing and dyeing ink for the direct inkjet textile comprises red printing and dyeing ink / yellow printing and dyeing ink / blue printing and dyeing ink / black printing and dyeing ink, and the preparation method of the printing and dyeing ink for the direct inkjet textile is as follows: weighing the reactive dye, the N-methyl-2-pyrrolidone, the ethylene glycol monomethyl ether, the isopropanol, the propanetriol, the triethanolamine and the deionized water respectively, placing in a stirring container, stirring uniformly, then standing, and filtering so as to get a finished product, namely the printing and dyeing ink for the direct inkjet textile. The printing and dyeing ink is excellent in quality, low in price, applicable to different models of inkjet printing machines, abundant and bright in color, strong in stability, strong in coloring power and small in undissolved substances, and can be used for automatically cleaning a spray head, ensuring no blockage and achieving good flowability and smooth jet; and furthermore, wrinkling and diffusion of an image of the direct inkjet textile can be avoided, the color fastness is high, the resistance to ultraviolet radiation is realized, the image can be preserved for 20 years without color fading, and the inkjet printing machine in a shutdown statecan not block the head within half a year.
