The anilox roll of few line number could meet the ink amount of trace, followed by according to the blotting amount of printable fabric, in the version chromatography of preliminary school
Cheng Zhong observes form and aspect, saturation degree etc. per color trace, selects suitable anilox roll；
（2）Select ink：Using color fixed on colour code, reach required printing knot with the printing of Essential colour and secondary colour
The ink of fruit, selection generally selects novel aqueous ink and purple with the adaptable ink viscosity of printable fabric and surface tension
Outer ink；
（3）The inspection of printable fabric surface tension：Using dyne value test pen and surface tension test liquid to the tension of material into
Row test, the surface tension of plastic film reach 3.8 × 10-2N/m, you can for printing；
（4）The selection and adjusting of doctor：In order to ensure ink supply effect and improve anilox roll, the service life of doctor, it is necessary to
The angle formed between doctor and anilox roll is adjusted, size determines the pressure of the height and doctor of screen density, angle
Control is at 30 ° -40 °, and the pressure adjusting of doctor is subject to the removing of anilox roll excess surface ink whole totally, and pressure should not mistake
Greatly, in order to avoid damaging anilox roll；
（5）The selection of double faced adhesive tape：Flexographic printing needs to be pasted onto plate cylinder surface by a kind of dedicated double faced adhesive tape,
Energy one complete printing cylinder of performance, the thickness for the double faced adhesive tape that flexographic plate uses is 0.38mm, 0.50mm；
（6）Determine printing color-sequential：According to the importance of color on printing machine type, printed matter, chromatography precision, paper property,
The property of ink, the mode of ink trapping, the depth of color, the size of picture and text area determines printing color-sequential on printing plate；
（7）Printing operation：Carry out successively coiled strip, paper feed, adjustment correction, dress anilox roll, upper roller, adjust three drum pressures,
With ink, coining, register, tension force, drying, cross cutting, cutting, winding.

Line/cm.
3. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（2）The ink of middle selection
Need that there is sufficiently high ink solid pigment content, and the rate of drying of ink is adapted with print speed printing speed.
4. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（4）In for having ground
The doctor blade of damage should be replaced in time, otherwise can not ensure ink transfer quality.
5. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（5）Middle cable version and thin
1115 type double faced adhesive tape of low-density in being selected when print lines, 1015 type double faced adhesive tape of density in selecting when word and print lines
Band selects high density 411DL type double faced adhesive tapes when field printing.
6. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（6）In for four color nets
Line version printing, the color-sequential used for YMCK or YKMC, for spot color version printing be it is first shallow after it is deep, fold color printing be it is first secondary after it is main.
7. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（7）The paper road of middle paper feed
By dancing roll, Deviation rectifier, jockey pulley, printed impression drum, drying box, die cutting roller, cutting roller etc., paper feed requires steady, conjunction
Suitable tension force neither occurs breaking paper nor curl phenomenon occurs, while also needing to carry out paper correction processing：It allows and holds
Print centre when object edge passes through probe sensor, when adjustment makes Deviation rectifier maintain it in the interposition to swing
It sets, to ensure that correction action is accurate.
8. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（7）Three rollers of middle adjusting
Pressure refers to that pressure is adjusted between the adjusting and plate cylinder and impression cylinder of pressure between ceramic anilox roller and plate cylinder, first
The pressure between plate cylinder and impression cylinder is mixed up, then anilox roll is close to plate cylinder, observation anilox roll is to plate cylinder figure
The ink transfer situation and trace on literary surface transfer situation, and the pressure at two ends fine tuning screw rod for adjusting corresponding roller carries out, from light to heavy into
Row, the three roller depth of parallelisms after adjusting are good, and roller pressure at two ends is equal.
9. a kind of adagio printing technology according to claim 1, it is characterised in that：The step（7）It is middle according to printing material
The factors such as thickness, quality, quality requirement, the print speed printing speed of material control tension.
