The process flow of printing orders is:

    After reviewing the sample, making a small sample, confirming, placing the sample, confirming again, and officially producing

    The color difference of large and small samples mainly occurs in the process of placing middle samples. To solve this problem, the following methods can be used.

    (1) Improving the basic work: do a single-color increase rate test for various dyes, make a set of manual scratch printing and machine scratch printing in the laboratory, and make a sample; randomly select several kinds of dyes to make a large machine-printed steam box Steaming, machine-printing small steaming box steaming, hand-printing big steaming box steaming, hand-printing small steaming box steaming, and doing machine-printing machine washing, machine-printing hand washing, hand-printing machine washing, hand-printing hand-washing and other comparative tests, and making Into a sample. Analyzing these samples together, we can find out the ratio of handprints and machine-printed colors, as well as the difference between large steamer steaming and small steamer steaming, manual washing and machine washing.

    (2) Add a machine-scraping sample process: add a machine-scraping sample program between the two procedures of sample confirmation and placement.

    (3) Strictly control controllable factors: there are many controllable factors between the printing sample and mass production, such as the name, strength, and place of origin of dyes and auxiliaries; the original paste preparation method, the ratio of paste, and the type of original paste Wait.
         The simple control method for these factors is: After the sample is confirmed, according to the sample formula and the color ratio of the comprehensive handprint and machine printing, formulate the on-machine scraping formula, and prepare the color paste according to the width of 15-20cm for each color. Calculate the number of printed colors and paste the blank silk on the printing belt, make a lofting pattern, add slurry and start scraping, after scraping, drying, steaming, washing, ironing, adjust the formula and scrape the sample until all The color numbers are up to the sample. Generally, it is enough to use experience once, and individual color numbers need to be adjusted 1-2 times. On-machine scratch-printing of samples basically does not take up the formal machine-printing production time, but uses its production auxiliary time to carry out, thus achieving a scientific and economical effect. Strictly control various controllable factors between large-scale production and samples, which has achieved great results in actual production.
