Analysis of common problems in textile printer machine:
 
(1) The oil leakage of thermosetting ink textile printer machine: the temperature is not up to the temperature, and it is not completely dried; the substrate does not meet the requirements of thermosetting ink printing (such as waterproof cloth, coated cloth, etc.), and there is no permeability Fabrics are prone to oil leakage on the surface; excessive addition of diluents or additives in the ink.
 
(2) The surface of the ink layer is blistering, the pattern is not smooth, and the appearance is ugly: the curing temperature is too high and the time is too long; the distance between the heating tube and the substrate is too close or the distance between the hot air and the printing pattern is too close, or the curing temperature is too high and the speed is too high Slow; add thinners or additives by mistake; poor printing environment, excessive dust, chipped or not straight, blocked screen or uneven printing table.
 
(3) Poor adhesion, easy to fade: the curing temperature is not enough, and the curing is not complete; although the curing temperature and time meet the requirements, the power cannot be reached, so that the surface of the ink layer melts and the bottom cannot reach the curing temperature, resulting in the ink cannot be completely cured (Especially three-dimensional and thick version printing); the selected printing materials cannot meet the requirements of thermosetting ink printing.
 
(4) Color migration and discoloration: The curing temperature is not enough, and the ink layer is not completely cured; the printing substrate uses disperse dyes, and the printed pieces are heated to a certain temperature during heat treatment, and the dyes in the fabric will sublime and cause color migration; Color inks with poor migration resistance are used for color printing, such as purple, peach and fluorescent colors; the curing temperature of the ink is too high, especially the fluorescent color or the ink with brighter colors. Generally, the heat resistance is relatively poor. The pigment is prone to discoloration during curing.
 
(5) The surface of the printed pattern is not clear, and the text and lines are not fine: the quality of the printed screen is poor (the pattern effect is not good, the tension of the two plates is not enough, or the printing equipment, the process is poor); the printing process is poor (scraping pressure during printing Uneven); Improper adjustment of ink viscosity; The printing substrate is too rough to meet the requirements of fine printing.
 
(6) The ink collapses during the three-dimensional effect: the film of the printing screen is too thick; the scraping pressure is too large or uneven during printing; the ink layer surface is not dried before overprinting; the temperature is too high during curing, or the curing time is too long .
