If it is not for the seal industry, 99% of people have a vague concept about the atomic seal. In fact, many people regard the seals packed with the atomic seal as atomic prints, in fact, they automatically produce oil and use a uniform atomic seal. There are four kinds of seals on the outer casing, which are: Machine-engraved infiltration (also known as domestic atomic printing), characterized by low price and good quality. The effect is relatively poor in the four seals, but there is still a certain seal compared to the common material. Advantages, the production method is to put the penetrating stamp pad on the laser engraving machine for engraving, and then carry out the refueling shell. Open the lid to see the subtle laser engraving marks on the printing surface. It can be repeatedly oiled. Disadvantages: the ink is easy to volatilize, and the imprinting is more obvious. Photosensitive seal (seal feature: photosensitive seal with imported photosensitive seal special pad, the printed surface is black, and the letter surface maintains a horizontal depth of 0.1-0.3MM. Seal production process: typesetting - laser printing - printing pad exposure imaging - refueling - housing And other procedures. Seal features: the seal is clear and delicate.

 

 

 

Seal life: 3000-5000 times in a single use (depending on the size of the seal and the content), it can be used repeatedly, with a total life of more than 100,000 times. Refueling method: Invert the stamp, put 3-4 drops of special photosensitive oil droplets (specifically according to the size of the seal and the ink consumption program) for more than ten minutes, wait until the ink is slowly infiltrated, and then wipe the surface with excess ink on the paper towel. Just fine. Disadvantages: The stamping effect is not ideal when making a large seal. Penetration printing (characteristics are relatively low price, the effect is not bad, the printing surface is uneven, the printing surface is smooth, the molding is made, the oil can be repeatedly refueled, the shortcomings, the imprint has obvious penetration marks. Advantages, some relatively large seals are not suitable for photosensitive printing It is used for permeation printing, and it is better to cover.) Imported atomic printing is also the real atomic printing. It is the highest price among the four seals. The production method is more complicated. It is made by hot die casting method. Smooth and delicate, the print is clear and quick-drying. Disadvantages: The price is too high and cannot be used repeatedly.
