1 design of the main exhibition area
Because of its relatively small size, while the image itself is a product designed to quickly screen products introduced to consumers, the use of text and close-up image of the direct expression of the way.
(2) the overall design
Partially due to the main exhibition area is not, should not be isolated, to consider the overall image of the packaging, through text, graphics and color consistency between, repeat, echo, and segmentation techniques, the formation of the overall composition.
Printed matter must know before
1 the rational application of color
Paper will make the color appear unexpected deviation. Designers should be aware of the same white paper, the degree of white between them warm or cool, it will affect the printing color changes, such as yellow printed on white paper will cool greenish yellow, printed on the side The white paper will warm reddish. Especially for the application of colored art paper, but be careful, be aware of. In addition, the loose texture of the paper will be more ink, the color will be printed after the bleak feeling. This means that different ink absorption of paper surfaces more or less, even in the same sheet of paper printed on different presses the actual network is also different. Air humidity also impact on the paper. A good designer should know how to use the paper to enhance the design characteristics of the effect, when the final paper in contact with the ink, creativity can truly reflected. Cross-box to change the color of the surface is very dangerous, especially for large size. Very high quality boxes. Even in the best case, the indentation will not fold up very precise degree.
Transfer printing bag printing and packaging printing machine plastic printing software, printing equipment, food packaging EPE EPE.
As the indentation even the slightest error, when the tray folds, there will be a face of color was folded into another plane. Do not exclaim the color of printed materials on the computer screen display very different colors, color printing is based on the chromatogram recorded by printing the sample, enter the correct data to the computer, the yardstick. For high-quality packaging boxes. Try not to take off more than make-up printing. Because offset printing is the printing units across the entire width of a single ink fountain will be sent to the rotation of the roller on each fountain is controlled independently and work, the increase of network is inevitable, especially for a large area at the end of color of the box, more difficult to control the entire layout on the left and right off the tray color uniformity.
For some by four-color overlay of color can not be printed, such as dark red, brilliant purple, and fluorescent colors, etc., should be considered with additional application-specific color printing. For large-scale version of the background field to take second printing in order to make the background uniform. On the ground do not grin, while taking some tips to make the picture even more engaging and rich, such as the site for the black version, can be taken to be the blue print of a 30% , and then print the black spot, which will enable a more solid black mystery. To know with the yellow ink on the printing press is almost transparent, and can not print high concentration of yellow, magenta must consider increasing the number, the resulting increase in trapping. Thick film can increase the sense of the screen, but the color of the screen will dim slightly.
(2) the rational application of paper
The most commonly used paper (the size of the entire open), there are two specifications: the standard paper size length 787mm, width 1092mm; special paper size length 880mm, width 1230mm; imported paper still long for the 889mm, width of their 94mm and other specifications. When printing machine according to the size of the car, generally the whole car, the car and four cars. Small sixteen open offset vehicles. To avoid waste, designers must consider when designing the size of the finished carton or as close to you in line to be used to open on the number of paper machine. Clever use of the roof and bottom tray into each other, and to borrow insert (tongue) parts of sets containing the full use of paper.
3 Indian workers and others note
Indian workers are often determined by the print run, generally to 50 sheets of paper turn on the machine once a printed work (less than 5000 count 5000) principle, four colors to 4 times for 4 Indian workers. The size of the paper machine is opened more than a few subject, not in boxes the size of the subject, the four drove off the machine and printing machine work on basically the same. Which can be printed according to the number of rational choice of four on or off the machine more economical. If the designer can some of the four-color overlay of color designed by the spot-color printing of a printed work, then it would reduce costs, cost savings. For large area of ??color and spot color spot color large area, due to the second printing, printing workers have considered two chromatic. Indian gold or silver print work is considered two chromatic. Gilt, silver, gold and rolled uneven color printing is generally considered three chromatic work, but also to calculate the area under the gilt. Therefore, when the designer in the design of the screen in order to save costs, so as not to gilt and other parts of the site designed to be too fragmented between.
Product packaging design color screen is just a draft blueprint on paper, not the finished product packaging, it must pass over a series of production processes can be achieved. Designers to achieve the desired results, we must understand the lithographic printing production process. Modern packaging molding process: design of a production printing draft a separation, a printing plate (including rolling embossing, hot stamping, foil) a rolling case a bond forming. Packaging design printing is the most basic, the most important processes. The so-called printing is to a variety of different ways, through a printed version of the text or graphics system, a large number of copies of salt. Different printing processes have different characteristics, the present paper, the printing process, there are two main methods: stereotype, copperplate printing, also known as letterpress printing, letterpress printing presses is a small semi-manual machines; other species is more advanced offset printing, also known as flat printing, offset printing presses with a small offset and large offset presses. With flat printing letterpress printing because the printing process is different from the results obtained are very different, the design requirements of the draft design is also different. Therefore, the design will be used before you have to consider what kind of printing method, in particular, must understand the use of letterpress or offset printing.
1 Toppan Printing
Toppan Printing draft design must be based on color addition and then draw the distinction between black and white colors of registering draft. Letterpress printing for packaging, the black and white draft is a very important part. It directly to photographic. Black and white draft drawn properly, or does not match with the original, will not affect the sub-version of the printed results. Pay attention to put the incision, the incision is printed after the printing of that part with the knife, the incision must generally stay 3mm. If the drawings of the color is not blank side through the side, painted black and white draft release of 2-3mm when the bleeding. This cut is finished after the printing will not reveal the white side, and draw out the net size line (product line), hair size wire. Finally, the manuscript must be drawn up and down about the middle of the crosshairs, so that when the make-up printing plate production.
(2) offset printing plate
Offset printing plate is made of plate design can draft draft draft of the plate on the color or color photographic images for network scanning via computer control. Either letterpress or offset printing, carton packaging has its particularity, it must also draw the knife grinding tray structure diagram, as required, to draw out the make-up map. Tray is used to map the structure row of knife blade grinding mill, paper mill after the printing needs of a knife to cut the finished product, and the rolling fold line. Therefore, tool wear and design plans must be consistent with the structure map, the location of the structure line can not have any errors. Otherwise, the structure of the line error box will appear after rolling to the top or bottom of the structure of partial to, and make the entire surface of the box errors, make-up chart is based on the characteristics of the printing machine to produce, if the plate is a draft of the gross size six to open the case, but the machine is on the four open car, then you need to open the plate is issued to sixteen quarto makes up the drawings, leaving the make-up tray and the tray between the cut edge 3mm. Must stay out of the paper machine, paper machine seams of about 10mm. Easy to burn out before the printing plate was made after the basis of use, finally leaving a paper throwing flash repair 10mm, generally grinding map and knife drawing into a make-up can be.
