What are the factors that affect the choice of raw materials for hand stamping machine? The original ink material of hand stamping machine becomes thinner with the stirring action when it is stirred by external force, and returns to the original consistency when the stirring action stops. Due to the thixotropy of the raw ink material of the hand stamping machine, the raw ink material of the hand stamping machine will increase the fluidity and ductility after being rotated by the printing press on the ink roller, so that the raw ink material of the hand stamping machine is easy to transfer; When the original ink material of the hand pressing bronzing machine is transferred to the paper by printing, due to the loss of the action of external force, the original ink material of the hand pressing bronzing machine is thickened from thin and does not flow around, forming a good imprint.

If the thixotropy of the raw ink material of the hand stamping machine is too large, the raw ink material of the hand stamping machine in the printer is not easy to rotate, which will affect the ink transfer function of the ink roller. Its influence factors mainly have the following two kinds:

I. Liquidity

It means that the raw ink material of the hand pressing bronzing machine will flow like a liquid under its own gravity, which is determined by the viscosity, yield value and thixotropy of the raw ink material of the hand pressing bronzing machine, and is also closely related to temperature. The fluidity of the raw ink material of the hand pressing bronzing machine can be poured out of the container, transported from the ink storage tank to the printer's printer, transferred smoothly from the printer, distributed well on the printing press, transferred to the layout and transferred to the substrate, but also affects the printing effect.

Two, the length of ink

It refers to the degree to which the raw ink material of the hand pressing bronzing machine is initially stretched into a filamentous shape without breaking. Its length is related to the thixotropy, yield value and plastic viscosity of the raw ink material of the hand pressing bronzing machine. The raw ink material of hand pressing bronzing machine with short ink wire is the raw ink material of hand pressing bronzing machine with good printing performance in offset printing and relief printing. It will not cause flying ink phenomenon in the printing process. At the same time, the ink layer on the printed matter is uniform and thick. The length of ink wire is a commonly used method to measure the performance of the original ink material of hand stamping machine.
