Used in domestic outfit and the male pack two main market color glass through the screen printing, the basic production elements to realize for: net edition + ink printing equipment, general + net edition and printing equipment can entrust the system, and variability in ink: key element control is divided into two kinds: here 1, printing ink; 2, spray, printing ink. The main operation technology elements have the following:
A, printing ink (refers to the glass screen printing special ink SG series) : 1: color, 12 special color + outlets four color palette 2 + + can measures: adhesion, more than four. Test (1) : 3 M two-side glue to stick attached stripping pressure, did not see the color marks. (2) the habitual resist scratching with no broken fingernail crack. 3: application: in the emulsion (or hair surface) glass, diluted 783 direct printing; In flat (or smooth) glass seal back when besmear after can be directly printing; In flat (or smooth) glass printing with no independent back can be added when 8 to 10% SG677 curing agent. 4: dry: under normal temperature table dry 20 to 30 minutes, 8 to 10 hours action (from dry), such as mandatory speed dry curing in India should be implemented after 80 ° constant temperature 10 or 15 minutes.
Second, printing control in the process of operation (attention) : 1, the nets from: when printed nets edition don't cling to in glass printing (content), should keep 1-2 cm. 2, by scraping ink: after printing ink to blow gently back, even in nets territory covered ink, avoid dry version of wen. 3, color mixing: before printing ink will adjust lewd facies additives, quiet place defoaming about 1 hour after use. 4, test: a sampling XiaoBan preset, will adjust the good ink small area after the test, ShiYin expected after passing, avoid uncertainty factors in the paper went to bed at fault. 5, nets version: appropriate chooses 180 mesh-300 mesh monofilament nets cloth, tension in the 20 + 2 Newton, oily photosensitive plastic or water oil compatibility photosensitive plastic made of sun, its net edition print resistance and corrosion rate was higher solvent (cleaning) good performance, in order to reduce the cost.
Three, diluted and cleaning: 1, printing ink diluted should choose matching additives, here for IP783 slow dry water, Germany, the original high purity, good stability, do not affect attached, dilute for 15-25%, than moderate viscosity, be helpful for printing operations. 2, the nets version cleansing, after the completion of the single printing wash to seal, elected SG833 open version water spray, or sheet of both the local pressure fully. 3: the implementation of printing machine, cleaning process, nets version or blow up in India reason clear or dirty imperfection on choose when the diffusion, cleaning type printing ink spray cleaning 807 after scrubbing dry.
Four, note: 1, the spray sex with SE series back to use should be constant temperature, 150 ° device configuration ~ 170 ° drying 10-20 minutes, oil and water dilute open than 2:1, 2 Kg is to add 1 Kg spray the color open oil and water. 2, article mirror type mirror silver ink film after spraying 2-3 isolation over into film is reasonable. Article 3, 70 ° scrape hardness choose-75 ° suitable.
