Atomic seal: it belongs to modern high-tech products. It stores the ink in the inner core of the seal, and then makes the inner core into the shape of the printing surface, so that the ink oozes from the inner core every time the seal is stamped, and it is not necessary to print the ink on the printing table every time the seal is stamped, which improves the efficiency of office production.
The difference between atomic seal and photosensitive seal;
1. Seal refueling:
Atomic seals need to be oiled repeatedly, and ink is easy to volatilize and spread. Invert the seal, invert 3-4 drops of special oil for photosensitive seal (depending on the seal size and printing oil program) 10 minutes or more, and then gently wipe off the excess printing oil on the surface with a paper towel.
2. Materials used:
Atomic seals are cheap and of average quality. The manufacturing method is to carve the permeable gasket on a laser engraving machine. The photosensitive seal adopts imported special pad for photosensitive seal, and the printing surface is black, keeping the horizontal depth of 0. 1-0.3MM with the text.
The special photosensitive material for photosensitive seal is a kind of ultrafine bubble material, and the pore size of its surface micropores is very small, with an average pore size of less than 30 microns. It has the characteristics of oil storage, oil seepage and light flash melting.
3. Service life:
The photosensitive seal can be used for 654.38+00000 times at a time, and can be used continuously for about 100000 times. The life of an atomic seal depends directly on its material, and good raw materials can prolong the service life of the seal. The atomic seal products made of imported raw materials have stable quality, simple operation and few maintenance times, and can be stamped more than 10000 times, which can directly reduce the procurement cost.
Extended data board
That is, the ink storage material of the seal, the ink storage performance of the pad and the density of the pad determine the clarity of the imprint and whether the ink seeps back and leaks. Generally, imported mats have better performance and higher price than domestic mats or composite mats. The imported pad can be used for 20,000 to 30,000 times before it is damaged. However, the imported pad can not be refueled after storing ink, or the effect is worse after refueling, and it will be scrapped after being stamped for about 10 thousand times.
stamp-pad ink
Printing ink should be judged from the color of printing color and silk adhesion. Generally, imported mimeographed products are bright in color, bright and oily, with dazzling marks, oil-proof, waterproof and colorfast. However, the domestic oil is dull in color, light in dispersion, dispersed in water, faded, and will soon leak traces.
Sealed shell
Whether the print box has the function of adjusting the printing depth (or protection file) depends on the balance between the handle spindle pressing and the control handle feel. These aspects play a great role in the life and use effect of seals. Generally, domestic printing cases do not have the above functions.
