Substrates, printing ink and other materials match the printing conditions, suitable for printing work performance, is called a printing eligibility.

Ink, printing eligibility, refers to the ink match the printing conditions, suitable for printing work performance. Mainly include viscosity, viscosity, thixotropy, dry, etc.

Ink viscosity

Ink in the flow of internal friction characteristics, called ink viscosity, measure ink viscosity parameters, called the viscosity of the ink.

The viscosity of the ink viscosity meter can be used to measure, commonly used viscometer has parallel plate viscometer, rotational viscometer, raleigh viscometer, etc.

Printing presses, the faster you require ink liquidity is larger, the smaller the viscosity.

Ink viscosity, can be used to adjust the oil ink or ink thinner.

Ink viscosity of

Ink from the ink fountain to ink roller, plate, surface transfer (blanket) substrates, printing ink film first division, and then transfer, ink film shown in this dynamic process to prevent ink film rupture of ability, called ink viscosity. Quantity of measurement ink viscosity, called ink Tack value.

Ink Tack value can use the ink viscosity meter to measure.

Printing process, if the ink viscosity and the performance of the substrates, printing conditions don't match, the paper will happen off powder, wool, bad ink dieyin, print the dirt of printing failures.

Ink viscosity, can be used to adjust the adhesive or ZY ink additives.
