How To Improve Printing Halo? Everyone Look!
Nov 25, 2016

Printed halo of classification and causes

1. print Halo around the entire print design:

Have a Halo around the entire printed pattern, usually because the printing rollers and in the film due to too much pressure, cause deformations in the printed version of the extrusion process, namely printing pressure caused.

2. mark the front edge printing Halo:

Imprinted front edge Halo is usually the result of printing rollers and film pressure roller is applied to the plate caused by excessive stress. Which is caused by pressure is too high, or in print is not hung tight cause Halo.

3. all printing pattern printed Halo:

Is generally level, wear plates, bending, printing caused by dirt on the surface is not level, causing uneven thickness of ink and the ink layer is too thick halos, witness the print edition will also cause a Halo phenomenon. Rubber version of the Halo is easier as a result of print high hardness.

Second, proposals to improve printing Halo classic 9:

Printing a Halo appeared how can improve? Starting from the following 9 points:

1. takes note of anilox rollers and printing cylinders to reduce the gap between the pressure.

2. takes note of printing rollers and impression cylinders to reduce the distance between the pressure.

3. use liner plates of thin material, so that it remains appropriate to the thickness.

4. reinstall the plates make it close in the roller.

5. adjustments and reduce the roller pressure, check the level and layout of plates.

6. level the plates, fill the pit, dirt, or replace the plates.

7. adjusting the scraping device, Board and pressure roller, rollers parallel to the replacement of the printing plate.

8. reduce the thickness of the ink in the following way.

9. reducing ink density and use more soft plates at 35 degrees.
