In the field of printing, how to arrange the color overprinting order reasonably is an important subject studied by process technicians. The same printing job and printing process, if there is a slight difference in the arrangement of printing color sequence, the effect of the printed matter is completely different. This requires our printing operators and process arranging personnel to draw practical experience in print production, and combine it with the theoretical knowledge of ink color, in order to finally explore a more systematic and widely used color sequence Arrangement.
There are three reasons why the color sequence needs to be arranged: the effect of ink overprinting and the shortcomings of the ink color itself, the quality of the paper, and the human's ability to recognize colors. The most fundamental reason is the incomplete transparency of the printing ink itself, that is, the hiding power of the ink itself. The post-printing ink has a certain covering effect on the first-printed ink layer, so that the color displayed by the printed matter always focuses on the latter color, or on the mixed color of the back color and the front color. The starting point for choosing the color sequence is to flexibly arrange the color sequence according to the specific conditions of the original and the current process conditions, taking care of the main aspects (such as tone reproduction, color reproduction, graphic clarity, printing uniformity and printing repetition rate, etc.) .
Today, multi-color printing has occupied a dominant position in the printing industry. When we use a four-color printing press for production, how should we arrange the printing color sequence? First of all, the four-color machine generally adopts the printing color sequence with the increasing thickness of the ink film; secondly, there are many types of color printing and each has its own characteristics. Therefore, we must arrange the printing color sequence according to the characteristics of the product itself; again, the paper is in the printing process Through the roller rolling and dampening fluid, a certain degree of deformation and extension will occur, which will inevitably affect the accuracy of overprinting of printed products. From the analysis of overprint accuracy, how to choose the printing color sequence is the top priority to better ensure the registration of the printed products; the color sequence arrangement of four-color printing should be analyzed in specific situations and adjusted according to the actual situation. To achieve the best combination of printing quality, printing costs and printing operations. [Extended reading]: How to arrange the printing color sequence of the four-color machine?
Carton
packaging is to promote the beautification of goods and improve the
competitiveness of the products with its beautiful shape and decoration. Since
the shape and structural design of the carton are often determined by
the shape characteristics of the packaged goods, there are many types, such as rectangular, square, polygonal, shaped carton,
cylindrical, etc., but the manufacturing process is basically The same, that is, the selection of materials - design icons - manufacturing templates - stamping - joined into boxes.
The
raw materials are coated paper, special paper, powdered ash, kraft
paper, corrugated paper, which are used to hold items and can be
recycled.
Paper product packaging is the most widely used type in packaging industrial products. Carton
is the most important form of transport packaging, and carton is widely
used as a sales package for various products such as food, medicine,
and electronics. With
the change of transportation mode and the change of sales methods, the
styles of carton and carton are becoming more and more diversified.
Almost every new type of non-standard carton is accompanied by a set of
automatic equipment, and the carton itself is also becoming novel. With
the means of merchandising promotion, we believe that the future carton
packaging will develop in the direction of environmental protection
economy, and there will be a new form to show us.
