The invention discloses a printing method, device and equipment for any-fold ink quantity output and a storage medium, and relates to the technical field of ink-jet printing. The method comprises the steps that the reciprocating scanning frequency, initial stepping information and ink amount adjusting information of a to-be-printed task are obtained; actual printing stepping information is obtained according to the reciprocating scanning times and the ink amount adjusting information; processing the to-be-printed data corresponding to each type of to-be-adjusted ink according to the reciprocating scanning times and the ink amount adjustment multiple to obtain actual printing data; and controlling a printing nozzle and a printing medium to move relative to each other according to the actual printing stepping information, and performing ink jetting in the moving process according to the actual printing data. The technical problem that an existing printing method cannot conveniently and accurately output the doubled ink amount with any multiple can be solved.

This invention discloses a direct-to-garment printing method using organic plant dyes, relating to the field of digital printing technology. It addresses the technical problem of adjusting the printhead's dwell time at each printing point in real time based on the material and thickness of the object being printed and the temperature during printing. The method includes the following steps: importing the pattern file to be printed into an image processing module; scaling and rotating the pattern according to the printing area of ​​the object; positioning the printing area of ​​the object; inputting the fabric type of the printing area and assigning it to a direct-to-garment printing fabric category; and detecting the fabric thickness. Based on the thickness of different fabrics and the different characteristics of the printing area, the method adjusts the printhead's dwell time at each printing point in real time, improving the quality and accuracy of the printing.

The utility model relates to the technical field of seals, and provides an ink box and a rotary printer. The utility model provides an ink box which comprises an outer shell, an ink storage mechanism and a printing nozzle. The printing nozzle has a printing position and a dismounting position; the outer shell is connected with the printing nozzle, so that the printing nozzle can be switched between a printing position and a dismounting position; the printing nozzle is provided with an ink inlet hole; the ink storage mechanism is detachably arranged on the outer shell and provided with an ink storage cavity and an ink outlet hole capable of being communicated with the ink storage cavity. When the printing nozzle is located at the printing position, the ink outlet hole is communicated with the ink inlet hole; when the printing nozzle is located at the dismounting position, the ink outlet hole and the ink inlet hole are disconnected, and the ink storage mechanism can be dismounted from the outer shell. The technical problem of high ink box replacement cost caused by the fact that the ink storage mechanism cannot be replaced independently in the prior art is solved.

The utility model discloses a kind of constant temperature device of gravure press ink, it is related to printing technical field, including the cooling assembly for communicating ink groove and ink storage tank, cooling assembly is used to carry out cooling treatment to the ink conveyed between both;The cooling assembly includes the cylinder with built-in cooling pipeline, cooling pipeline is used to generate cooling environment atmosphere inside cylinder, cylinder is connected with ink groove, ink storage tank respectively, to make the ink by ink storage tank into cylinder is cooled and is discharged to ink groove with cooling.This utility model connects ink groove and ink storage tank by cooling assembly, realizes the active cooling treatment to ink, this design not only can replace original conveying pipeline to ink groove play the function of feeding, and it has the cooling function to ink, can effectively control ink temperature, prevent viscosity change or printing quality problem caused by ink overheating, to ensure the stability and consistency of printing process.

This utility model discloses an intelligent temperature-controlled printing device for printed materials, relating to the field of printing technology. It includes: a base with a support rod on top; a printing mechanism mounted on the base, comprising a printing box and a printing device, the printing box being fixedly connected to the top of the base, and the printing device installed inside the printing box; and a temperature-sensing mechanism located inside the printing box for temperature sensing during the printing process. This intelligent temperature-controlled printing device, through the use of the temperature-sensing mechanism, can monitor the temperature of the paper, thereby precisely controlling the temperature of the ink and printed materials, avoiding large temperature fluctuations that could affect usability, and improving overall production efficiency. Furthermore, through the use of the temperature control mechanism, it can control the temperature of the paper, and in conjunction with the temperature-sensing mechanism, avoid printing quality problems caused by temperature fluctuations. Moreover, it can adjust the temperature according to actual needs, avoiding unnecessary energy waste.
