Abstract: A digital inkjet transfer printing apparatus used for performing transfer printing on fabrics by virtue of digital inkjet printing is provided. The digital inkjet transfer printing apparatus includes: a blanket inkjet printing assembly, where the blanket inkjet printing assembly includes a digital inkjet machine for ejecting ink to a surface of a blanket to form an ink pattern; and a counterpressure transfer printing assembly, where the counterpressure transfer printing assembly includes a press roller and a back-up roller, the press roller generates a pressure towards the back-up roller when a fabric enters a transfer printing area between the press roller and the back-up roller to press a surface to be printed of the fabric against a surface of the blanket with the ink pattern, so as to transfer the ink pattern on the blanket to the surface to be printed of the fabric.

Abstract: A vertical double-sided rotary screen transfer printing apparatus includes a vertical rack and one or more pair of rotary screen transfer printing assemblies horizontally disposed opposite to each other. Each rotary screen transfer printing assembly includes a rotary screen plate roller and a transfer roller arranged parallel to each other. The rotary screen plate roller transfers a pattern onto the transfer roller serving as a temporary transfer carrier. The transfer roller transfers the pattern onto a fabric passing in a vertical direction between the rotary screen transfer printing assemblies opposite to each other.

Abstract: A color control method for four-color field jet dyeing is provided. The method includes: obtaining fabric parameters of a fabric to be dyed; obtaining a fabric sample color; ascertaining whether predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in a field jet dyeing database; if not, generating temporary pre-color-development color parameters based on the fabric parameters and the fabric sample color, taking the temporary pre-color-development color parameters as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric; and if yes, taking the predetermined pre-color-development color parameters in the field jet dyeing database as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric. A color control device and a color control system are further provided.

Abstract: A paperless transfer printing method includes the following steps: (a) printing, by a printing machine, aqueous ink onto a transfer printing temporary carrier in a set pattern, wherein a surface of the transfer printing temporary carrier is made of an elastic polymer material and a surface tension of the aqueous ink is less than the critical surface tension of the transfer printing temporary carrier; (b) drying the to-be-transferred pattern on the transfer printing temporary carrier; (c) wetting the transfer printing temporary carrier by using an aqueous surface tension increasing liquid; and (d) separating the aqueous solution or the aqueous dispersion liquid from the transfer printing temporary carrier at a tight-contact position between the transfer printing temporary carrier and the fabric, so that an aqueous ink dye is transferred onto the fiber of the fabric.
