When the ribbon printing, should pay attention to?

A lot of ribbon printing plants in the mass production of screen printing products, ribbon printing, ribbon printing processing, we need to pay attention to the problem of printing, screen is the basis of screen printing, screen selection is an indispensable link. Due to the printing processing, screen printing is very wide range of application, so it is related to many factors. In the selection of screen, according to the specific situation and printing requirements, to choose different printing screen, usually in the selection of screen can be considered from the following different angles.

(1) according to the ribbon printing, printing price of ribbon substrate type selection screen. According to the fiber fabric, paper products, glass, ceramics, metal, plastic, wood products, electronic products and other categories of choice.

(2) according to the nature of printing ink paste selection screen different ink has different characteristics. So in the selection of screen to consider the ink drying time and color sharpness, substrate ink absorption ability and other factors.

(3) according to the printing screen material and performance selection screen selection to consider the screen itself material and physical properties, according to the different suitability to choose the appropriate screen to be used as a printing material.

(4) according to the printing ribbon to mark the selection of screen, the selection of the principle of printing speed, printing pressure, printing plate resistance, substrate absorption capacity.

The selection of screen has been described in the previous several ways. But because of the choice of ribbon printing, printing processing screen is not a simple problem. In addition to consider screen, but also consider the cost of ink, substrate and other related constraints. Enjoy the selection of methods and pay attention to the relevant issues, choose the appropriate screen to be handy. Screen selection should pay attention to the following aspects.

(1) first consider the ink through the screen of difficulty, generally choose to consider this aspect more. Middle color ink to use transparent ink, fibrillation is expected to pull more subtle, and the ratio of relative fibrillation material chromatophore, which causes the ink, the ink when using high mesh screen can also be a good pass, general plastic ink better through sex, special-purpose inks, ink material high concentration of, although is a thin child its through sex is relatively poor.

(2) if the ribbon printing, ribbon printing grid belt pattern, printing processing substrate surface rough, generally use a lower mesh mesh. Such as leather, canvas, foaming body sheet, wood and other materials printing. Due to the substrate surface roughness, strong ink absorption so to use a lower mesh number of screen, to ensure that enough ink through.

(3) according to the original picture line fine selection screen. In contrast to the above situation, in general, fine lines to choose a high mesh mesh screen.

(4) the selection of screen also consider the cost, in the premise of meeting the requirements of printing, try to choose a lower price screen.
