5 factors affecting the drying effect of workshop prints

1. Effect of printing press drying system exhaust

If the exhaust system is not smooth, the solvent that is volatilized cannot be eliminated in time. Excessive solvent concentration in the oven will hinder further evaporation of the solvent, thereby affecting the drying effect of the print.

2. The effect of ink on drying

(1) The drying effect of the aqueous ink is closely related to the pH of the ink. Under the same conditions, when the pH value is too low, the drying speed of the ink is accelerated; when the pH value is too high, the drying speed of the ink is slow, and the back surface of the printed product is liable to be dirty.

(2) The volatilization speed of the mixed solvent in the solvent type ink directly determines the drying performance of the ink, and the volatilization speed of the different components in the mixed solvent is different. By mixing different kinds and different proportions of solvents, the solvent evaporation rate of the ink can be conveniently adjusted to improve the drying performance.

3. The effect of printing speed on drying

Different printing speeds have different requirements on the performance of the drying system. In the case of relatively high speed requirements, the heating distance and drying efficiency of the drying oven have relatively high requirements. If the associated drying system does not allow the solvent to fully evaporate, it is easy to cause excess solvent to exceed the standard.

4. The effect of printing plates on drying

For gravure printing, the depth of the plate pocket has a great influence on the drying speed, for example, a cell having a depth of 33 μm and a cell of 18 μm, the ink drying time of the former is more than one time more than that of the latter.

5. Impact of environmental conditions

Generally, printing in a temperature environment below 20 ° C, the natural drying of the ink should be weakened. Printing in an environment of 30 ° C or higher, the natural drying of the ink has an increasing tendency.

The effect of excessive air humidity on drying: First, the moisture in the air enters the ink, causing the overall volatility of the solvent to deteriorate; second, the presence of a large amount of moisture in the air inhibits the volatilization of the solvent.

CONTUO Electric Height Adjustable Desk includes five different series: Single Motor Sit Stand Desk, One Leg Sit Stand Desk, Two Legs Sit Stand Desk, Three Legs Sit Stand Desk, Four Legs Sit Stand Desk. CTT-D02 is our single motor sit stand desk, while CTT-01-C3 is a one leg Height Adjustable Desk with moving wheels.
