Offset Printing High Technical Difficulty

- Aug 10, 2017-

Offsctdruckereien has been in China's printing industry accounted for the majority of the territory, Offset Printing many enterprises do not dry glue label business,Offset Printing it has been useful offsctdruckereien to print the experience of the packaging box. Therefore, there are still customers to take the label effect on the packaging box to require labels printing enterprises to print the same effect of the label, Offset Printing this is a typical case of offset printing.

The sample provided by the customer is printed by a combined flexo printing machine with a offsctdruckereien device, and without a similar printing press, Offset Printing the offset part of the product must be converted to Flexo printing.

Order hours, with offset printing proofing, but when the order volume increased, Offset Printing beyond the expectations, have to offset printing to flexo printing.

Control Offsctdruckereien Ink Balance technology difficult, Offset Printing color stability is far less than flexo printing, customers often complain about the range of color error, so to offset printing to flexo printing.

Offsctdruckereien Flexo Printing must have a full understanding of Offsctdruckereien and flexo printing, so that the bottom of the heart can be converted successfully. Offset Printing According to the author's experience, the following Offsctdruckereien printing method.

Offsctdruckereien is the only one of the four printing methods of indirect printing, Offset Printing without printing indentation. Flexo printing is a light kiss type, light pressure, so it seems that Offsctdruckereien flexo printing is not a big problem. But some offset printing presses long open flexo printing opportunity habitually to set the pressure is very big, need to prevent.

Offsctdruckereien due to the existence of ink balance, water and ink blends with each other, Edge emulsification, so the printing outlets are not complete, the edge of the virtual. Offset Printing Plus is indirect printing, resulting in low ink transfer rate, ink color saturation and other drawbacks, resulting in the label industry, most of the Offsctdruckereien label product shelf effect is not strong. Offset Printing Flexo printing is a letterpress, thick ink layer. From this point of view, Offsctdruckereien Flexo printing should be no problem. But Flexo printing ink layer is too thick to cause plugging version, need to print or print two times.

Offsctdruckereien version of the number of lines can be easily reached 200lpi, Offset Printing plates on the gradient to zero dot can also be washed out, so the gradient to the absolute net extremely soft. The number of soft Inca cable is generally 175lpi, rarely 200lpi. Flexo version of the dot is too small, Offset Printing easy to penetrate the mesh roller mesh point, resulting in plugging version; Therefore, at this stage flexo printing to use high-definition dot technology can be comparable to offset printing effect of the gradient.

Offset-printing outlets have two-dimensional properties that vary in size and thickness. So on a board, due to the local adjustment of the amount of ink, Offset Printing the field can be printed more deeply, the dot can be printed more well. and FLEXO printing plate dot size can change, local ink thickness can not change. But the field needs thick ink, dot need shallow ink can be printed clearly and beautifully. Therefore, Offsctdruckereien to flexo printing, usually need to be in the field and dot version to print, so it is more easy to chase samples. But for the $number of the gradual discoloration, Flexo printing can not be divided version. Offset Printing At this time, usually need to print two layers to follow the sample, a layer of gradual gradient, printing ink layer shallow, another layer of a shorter gradient, Offset Printing printing ink layer can be a little thicker than one points, two layers of flexo printing in the field color equivalent to a layer of offset printing color. In this way, Offsctdruckereien to Flexo printing is very promising.
