Attention to detail
When the album is printed and designed, there is often a process of adding the background color, through which the album can be more personalized, although it is only a simple process, but it plays the finishing touch in the album, if it is used well, it can effectively enhance the artistic effect of the album, and the following is a detailed introduction to the relevant precautions when adding the background color to the album printing.
First of all, in order to make the background color of the batch of album prints consistent, envelope printing should be used, this process can make the ink layer more flat, and the printed layout will not be flowered and will not appear white spots, which can truly reflect the artistic effect of the original. In addition, spot colors can also be used for printing, which can highlight the characteristics of the picture and enhance the overall exquisiteness.
When printing design, the designer should try to use one or two spot colors as the background color of the album printing, not too complicated, there is no focus on a complex reading, the overall design effect should be as simple as possible, the selection of tones should be natural, and there should be harmony when it is excessive and changing, if the two tones are too different, it will also make people feel abrupt and uncomfortable, so the designer must skillfully use color to highlight the expression of the album when designing. Use visuals to motivate consumers to read.
In addition, in the selection of spot colors, it is necessary to follow the unity and conform to the connotation of the album. When printing, it is also necessary to ensure the consistency of the tone with the original manuscript as much as possible. In this way, the artistic effect of album printing can be effectively improved and the purpose of publicity can be achieved.
Influencing factors
(1) Blanket
There are two kinds of air cushion blanket and ordinary blanket commonly used in production, when it is in contact with the printing plate, due to the certain adsorption performance on the surface of the blanket, part of the dampening solution attached to the surface of the printing plate is transferred to the surface of the blanket. If part of the dampening solution is lost on the surface, it needs to be replenished in time, and the size of the replenishment amount will be balanced and unbalanced.
(2) Water roller
The water roller is the main part that is in direct contact with the printing plate and supplies the dampening solution at the same time, and the contact pressure between it and the printing plate is too heavy, which will damage the image part, and the dampening solution can not evenly coat the printing plate normally, and it is easy to appear "pattern plate". If the contact pressure is too light, the dampening solution on the surface of the printing plate is not applied normally, forming a situation similar to coating, and the phenomenon of "pattern plate" on the surface of the printing plate is obvious.
(3) The area of printing plates and texts
The amount of dampening solution required on the surface of the printing plate is directly related to the area of the graphic text. The area of graphics and texts is large, and the area of relative blank space is small; The area of the graphic and text is small, and the area of the relative blank space is large. In general, the amount of dampening solution required for printing plates with large graphic area is less, and the amount of dampening solution is more.
(4) Ink layer thickness
The thickness of the ink layer of the printed matter has a certain relationship with the amount of dampening solution on the surface of the printing plate. There are two ways to increase the thickness of the printing ink layer: one is to increase the amount of ink by changing the amount of dampening solution; First, the amount of ink remains unchanged, reducing the amount of dampening solution. The principle of these two ways is the same, they are under the condition of "water in oil" to increase the content of ink, reduce the content of fine water droplets in the ink on the layout, so as to achieve the purpose of increasing the thickness of the ink layer.
