1, note the use of offset printing white watermark:

1. To use the new roller, rollers, blanket, water, such as the use of the old must be thoroughly cleaned, so as to avoid ink on the residual ink exudation, affect the ink roller and printing effect;

We must increase the wettability powder more than 3-4 times in the bucket;

The ink on the PS version of high corrosive, PS version must be baked version, to increase the printing, and printing process to minimize the downtime, so as to accelerate the corrosion of the PS version of the. Recommend the use of good quality PS Version (such as Fuji PS version);

The amount of ink as far as possible to the maximum, to increase the permeability of the ink on paper;

The printing ink can be used as not good, hairdryer blowing on version of roller on the water, reduce the ink dry faster;

We must prevent the ink roller ink drying too quickly, the drying time is too long, otherwise it is difficult to clean the ink roller;

Offset printing watermark diluent, can join the 10-15% in ink, in order to reduce the speed to dry ink, ink and increase the permeability of the paper;

⑧ because the ink viscosity, regular cleaning agent is difficult to clean, can be used as a cleaning agent, reducing agent;
